RESUMEN
Background: Mammography, used for breast cancer (BC) screening, has limitations such as decreased sensitivity in dense breasts. Currently used tumor markers are insufficient in diagnosing breast cancer. In this study, we aimed to investigate the relationship between serum levels of synaptophysin-like protein 1 (SYPL1) and BC and compare SYPL1 with other blood tumor markers. Methods: The study group consisted of 80 female patients with a histopathological diagnosis of invasive BC who received no radiotherapy/chemotherapy. The control group was 72 women with no previous history of breast disease and evaluated as Breast Imaging Reporting and Data Systems (BI-RADS 1-2) on imaging. Serum SYPL1, cancer antigen 15-3 (CA 15-3), and carcinoembryonic antigen (CEA) were measured in both groups.
RESUMEN
BACKGROUND: Laparoscopic splenectomy (LS) is considered the gold standard treatment in adults with idiopathic thrombocytopenic purpura (ITP) refractory to medical therapy. However, the retrieval of the spleen in LS is still a technical challenge, despite the use of various commercial retrieval bags. This study reports the feasibility and reliability of using a saline bag for spleen retrieval in a reduced port splenectomy. METHODS: Between 2007 and 2020, 55 consecutive patients underwent LS for ITP. Data were collected retrospectively. To retrieve the spleen, a 1 liter sterile saline bag was used. RESULTS: Fifty-five patients underwent LS. There was only one complication related to the saline bag: an iatrogenic ileal injury during the morselization process. CONCLUSION: One-liter saline bag is feasible, and widely available. No additional instruments or cost is required and there is no need to extend the wound for spleen retrieval during LS. KEY WORDS: Idiopathic thrombocytopenic purpura, Laparoscopic surgery, Splenectomy, Techniques.

ABSTRACT: This study aims to evaluate the role of shearwave elastography (SWE) and superb microvascular imaging (SMI) for preoperative prediction of axillary lymph node metastasis (ALNM) in patients with breast cancer. In a cohort of 214 women with breast cancer, B-Mode ultrasonography (US), SMIvascular-index (SMIvi), and SWE (E-mean, E-ratio) values were recorded before tru-cut biopsy. Axillary fine-needle aspiration biopsy (FNAB) and sentinel lymph node sampling results were collected. Imaging findings and histopathological data were statistically compared. Receiver operating characteristic curve analysis was used to evaluate diagnostic performance. Reverse stepwise logistical regression analysis was conducted. Although ALNM was negative in 111 cases, it was positive in 103 patients. Axillary lymph node metastasis (+) group had larger size (P < 0.001), higher vascularization (SMIvi: 8.0 ± 6.0 versus 5.0 ± 4.3, P < 0.001), and higher elasticity value (E-mean: 129 ± 31 kPa versus 117.3 ± 40 kPa, P = 0.014). Axillary lymph node metastasis was observed statistically more frequently in Her-2 positive cases (P = 0.005). There was no significant difference between other B-mode US findings (P > 0.05), SMI Adler (P = 0.878), and E-ratio (P = 0.212). The most appropriate cutoff value for the prediction of ALNM was 23.5 mm for size, 3.8 for SMIvi, and 138.5 kPa for E-mean. The most sensitive (77%) method was the SMIvi measurement, while the most specific (86%) finding was Her-2 positivity. The combined model (being Her-2 positive, >23.5 cm, and >3.8 SMIvi) increased the specificity (78%), PPV (71%), and accuracy (68%). Although the increased size is a previously studied parameter in predicting the risk of ALNM, Her-2 and data obtained by SWE, and SMI can be used to assist conventional US.
RESUMEN
OBJECTIVES: The aim of this study was to investigate the role of superb microvascular imaging (SMI) and shear wave elastography (SWE) in the prediction of malignancy and invasiveness of isolated microcalcifications (MC) that can be visualized by ultrasonography (US). MATERIAL AND METHODS: Sixty-seven women with MC, who were considered suspicious on mammography were evaluated. Only those lesions that could be visualized by US and presented as non-mass lesion were included. They were evaluated by B-mode US, SMI, and SWE before US-guided core-needle biopsy. B-mode US, SMI (vascular index (SMIvi)), and SWE (E-mean, E-ratio) findings were compared with histopathologic features. RESULTS: Pathology confirmed 45 malignant (21 invasive and 24 in situ carcinomas) and 22 benign lesions. There was a statistically significant difference between malignant and benign groups in terms of size (P = .015), distortion (P = .028), cystic component (P < .001), E-mean (P < .001), E-ratio (P < .001), and SMIvi (P = .006). For differentiation of invasiveness E-mean (P = .002), E-ratio (P = .002), and SMIvi (P = .030) were statistically significant. According to ROC analysis E-mean (cut-off point at 38 kPa) was the most sensitive (78%) and the most specific (95%) value among four numeric parameters (size, SMI, E-mean, and E-ratio) with AUC = 0.895, PPV = 97%, and NPV = 68% in detecting malignancy. In the evaluation of invasiveness, the most sensitive (71.4%) method was SMI (cut-off point at 3.4) and the most specific (72%) method was E-mean (cut-off point at 91.5 kPa). CONCLUSION: Our study shows that adding SWE and SMI to the sonographic evaluation of MC would be an advantage for US-guided biopsy. Including suspicious areas according to SMI and SWE in the sampling area can help target the invasive part of the lesion and avoid underestimation of core biopsy.

AIM: Our aim is to identify the subgroups of women undergoing breast conserving surgery (BCS) who are at high risk for positive surgical margins and who require a re-excision procedure and understand the characteristics of tumor and hormone receptors that will allow surgeons to remove larger margins. MATERIAL AND METHODS: One hundred twenty-nine patients with invasive carcinoma in breast who underwent BCS were included in the study. Women with a positive surgical margin (n = 61) required re-excision procedure. RESULTS: Patients with high grade breast cancer, negative hormone receptor status, high Ki-67 status, upper outer quadrant tumor, and associated ductal carcinoma were more likely to undergo tumor removal and re-excision. CONCLUSION: The pathological and clinical predictors described above that meet these criteria require the removal of larger margins for safety in order to minimize the rate of positive surgical margins. KEY WORDS: Estrogen Receptor, Hormone receptor status, Positive surgical margin.

BACKGROUNDS: Optimal and tailored surgical treatment of phyllodes tumour(PT) of the breast is controversial. This study aims to determine the appropriate surgical margin in the treatment of PT. METHODOLOGY: The data of 132 patients who underwent breast surgery with the diagnosis of PT at the Breast Unit of Istanbul Faculty of Medicine from 2000 to 2022 were retrospectively reviewed. RESULTS: Median age was 38 and patients with benign PT were younger than others(median age was 34, 44, and 43 for benign, borderline, and malignant, respectively) (P = 0.001). Local recurrence was observed in 7 (5.3%) patients, systemic recurrence was observed in 3 (2.3%) patients, and disease-related death was observed in 2 (1.5%) patients. Local recurrence occurred in 1.4% (n = 1) of benign tumours, 8.3% (n = 2) of borderline tumours, and 10.3% (n = 4) of malignant tumours. All of the systemic recurrences and deaths were seen in the malignant group. The local recurrence rate was found to be higher in borderline and malignant tumours with surgical margins less than 10 mm (44.4% versus 3.7%, P = 0.003), and tumours larger than 5 cm (11.8% versus 1.3%, P = 0.015). In comparison, there was no correlation between the surgical margin proximity, tumour diameter, and local recurrence rates in benign PT (P > 0.05). CONCLUSION: According to our findings, negative surgical margins seem to be sufficient in the treatment of benign phyllodes tumours. Furthermore at least 1 cm negative surgical margins must be achieved for malignant and borderline phyllodes tumours to avoid local recurrence.

RATIONALE AND OBJECTIVES: To investigate the efficacy of the advanced imaging methods, superb microvascular imaging (SMI) and shear wave elastography (SWE) in predicting molecular subtypes in invasive breast carcinomas. MATERIALS AND METHODS: A total of 210 biopsy-proven breast carcinomas in 200 patients who underwent ultrasound (US) imaging with SMI and SWE were included in this study. Quantitative analyses were performed using mean elasticity (Emean) score by SWE and vascular index (VI) by SMI. For qualitative assessment of microvascularity, first, lesions were graded according to Adler's classification in four types. Then, a new morphological model was used to classify the microvascular architecture into six patterns: type one, no signal; type two, penetrant; type three, rim-like; type four, dot-like/linear/regional; type five, wheel-like and type six, irregular signals. The correlation between these variables and molecular subtypes, nuclear grade, the Ki-67 levels and axillary status was investigated. RESULTS: The average VI and Emean values were relatively higher in non-luminal subtypes (VI, p = 0.002; Emean, p > 0.05). The two microvascularisation models were significantly able to differentiate the molecular subtypes according to the Kruskal Wallis test (p < 0.05). Rim-like, penetrant and regional patterns were primarily observed in luminal subtypes. The dominant pattern in non-luminal subtypes was wheel-like pattern. VI, Emean, Adler's classification and morphological vascularisation model were not significantly correlated with the nuclear grade, Ki-67 index or axillary status. CONCLUSION: The proposed microvascular categorization model may be more valuable in predicting molecular subtypes of breast carcinomas compared to VI and Emean and may contribute to the management of breast carcinomas as a non-invasive variable.

ABSTRACT: The aim was to evaluate the effectiveness of superb microvascular imaging (SMI) in axillary lymph nodes (LNs).Benign and malignant LNs diagnosed via histopathological examination constituted the study subgroups. In addition to grayscale findings for morphological evaluation, vascular patterns and appearance of internal vessels were analyzed by both power Doppler ultrasound (PDUS) and SMI. The number of vascular branches was counted, and a vascularity index (VI) was calculated by SMI.Fifty-two LNs with suspicious findings in terms of metastasis (33 malignant and 19 benign) were evaluated. Diagnostic accuracy according to vascular patterns was 82% for PDUS and 92% for SMI. In the presence of asymmetric cortical thickening, there was a significant difference between benign and malignant LNs in the number of vascular branches of both thin and thick cortical sides ( P < 0.01). Mean VI was significantly higher in the malignant group ( P < 0.05). In differentiating malignancy, when a cutoff VI value was set to 9%, sensitivity was 69.7%, and specificity was 63.2%.Evaluating the vascularity of axillary LNs by SMI is a useful tool in determining the potential of axillary metastasis, especially in the absence of typical sonographic findings. Superb microvascular imaging can beneficially be used to select the most suspicious LN and suspicious area of the LN to sample.

PURPOSE: To investigate the relationship between sonographic findings and the axillary status, especially the side of thickening in the presence of cortical asymmetry. METHODS: Patients with biopsy-proven axillary lymph node (ALN) metastasis were included in this study. The lymph nodes were divided into three groups depending on the type of cortical thickening as diffuse, closer (eccentric cortical thickening on the side near the tumor and/or breast) and distant (thickening on the further side) asymmetry. Longitudinal to transverse axis (L/T) ratio, the largest cortical thickness, cortex to hilum ratio (C/H), hilar status (normal/displaced/absent), orientation (parallel/vertical), capsular integrity (sharp/indistinct), vascularisation pattern (hilar/peripheral/penetrant/anarchic/avascular) on superb microvascular imaging (SMI) and presence of conglomeration were recorded for each lymph node. Axillary nodal status on 18F-FDG PET-CT/MRI scans was recorded, if available. Features of the breast lesions like size, laterality, nuclear grade, hormone receptor status and the level of Ki-67 expression have been added. RESULTS: A total of 219 metastatic ALNs [diffuse (n = 122), closer asymmetry (n = 71), distant asymmetry (n = 26)] were evaluated. By the univariate analysis, ALN metastasis was significantly associated with the presence of closer asymmetrical cortical thickening (p < 0,0001), C/H ratio (p = 0.001), cortical thickness (p = 0.001), hilar status (p < 0.005) and vascular pattern (p < 0.005). L/T ratio was only a statistically significant parameter for lymph nodes with diffuse cortical enlargement in predicting metastasis, and conglomeration was also observed only in this group (p < 0.05). By multivariate analysis, nodal metastasis was significantly associated with asymmetrical cortical thickening (p = 0.001), C/H ratio (p = 0.005) and vascular pattern (p < 0.0001). CONCLUSION: Asymmetrical cortical enlargement on the side closer to the breast, C/H ratio and abnormal microvascular pattern are the independent predictors of axillary nodal involvement. Closer asymmetry is an eligible, easy-to-detect grayscale US finding to decide sampling that highly predicts ALN metastasis.

Objectives: Biliary cysts are biliary duct dilatations, with 20% of the cysts being diagnosed in adulthood. Abdominal pain, jaundice and palpable abdominal mass are defined as the classical triad. However, nausea, vomiting, fever, itching and weight loss are frequent complaints. There are several treatment options depending on the type of the cyst. This study aimed to share our experience with biliary cysts and contribute to the literature on this subject. Material and Methods: Thirty patients, who received treatment for biliary cyst from January 1981 to December 2018 at our clinic, were studied retrospectively. The patients were analyzed based on age, sex, type of the cyst, diagnosis and treatment methods, post-op follow up and complications. Results: Twenty-seven of the patients were females, and three were males. The patients were aged between 16 and 76 years, and the median age was 41.9 years. All patients presented with abdominal pain, which was accompanied by cholangitis in nine patients, nausea and vomiting in four patients, dyspepsia in three patients and palpable mass in one patient. According to the Todani classification, biliary cyst findings were consistent with Type I in 23 patients, Type V in three patients, Type IV in two patients, Type II in one patient and Type III in one patient. Conclusion: Diagnosis and treatment are complex in biliary cysts due to anatomical proximity and variations. Therefore, it would be beneficial to refer them to referral centers. Choice of treatment should be based on the type of the cyst.
RESUMEN
Objectives: The aim of this study was to determine the DNA and genotypes of Echinococcus granulosus in liver cyst hydatids isolated in humans. Material and Methods: This study was conducted prospectively at the Department of General Surgery of the Cerrahpasa School of Medicine, University of Istanbul-Cerrahpasa, between January 2015 and June 2016 in 30 patients who were operated on for cystic Echinococcosis. E. granulosus DNA was analyzed using the Polymerase Chain Reaction (PCR) method in the cyst samples (protoscolex and/or germinative membrane) obtained during the operation, and genotype was determined in the PCR positive samples by sequence analysis. At the same time, indirect hemagglutination (IHA) was used to test for the presence of antibodies in the patients' blood. Results: E. granulosus DNA was found in 29 out of 30 cystic Echinococcosis of the liver samples. All of the 29 cystic Echinococcosis samples were found to be G1 (sheep) species. Also, IHA was positive in 22 patients and negative in eight patients. Conclusion: In the present study, G1 species was the most commonly seen liver cystic Echinococcosis species. We suggest that a vaccine, which could be developed against prevalent regional genotypes, would be efficacious in the prevention of the disease with a cause of mortality and morbidity.
RESUMEN
BACKGROUND: Gallbladder and biliary tract infections are diseases with high mortality rates if they are not treated properly. Microbiological evaluation of perioperatively collected samples both ensures proper treatment of patients and guides empirical treatment due to the determination of microorganism susceptibility. AIMS: This study aimed to isolate the microorganisms in bile cultures from patients who underwent cholecystectomy and to determine sensitivity results of these microorganisms. METHODS: This study was a multi-center and prospective design, included 360 patients, and was performed between 2019 and 2020. Culture results of bile taken during cholecystectomy were evaluated. RESULTS: Bacterial growth was found in the bile cultures of 84 out of 360 (23.3%) patients. Patients were divided into two groups according to whether they had risk factors for resistant microorganisms or not. While Escherichia coli (n = 11, 13%), Enterococcus spp. (n = 8, 9.5%), and Enterobacter spp. (n = 4, 4.7%) were detected most frequently in patients without risk. Staphylococcus spp. (n = 17, 20.2%), Enterococcus spp. (n = 16, 19%), and E. coli (n = 8, 9.5%) were the most frequently found microorganism at-risk patients. In multivariate analysis, bile culture positivity was found higher in patients who had history of biliary disease (p = 0.004), operation performed concurrently with a cholecystectomy (p = 0.035), and high rate of polymorphonuclear leukocytes (PNL) in total leukocyte count (p = 0.001). CONCLUSIONS: Our study shows that when starting empirical antibiotic treatment for bile ducts, whether patients are at risk for the development of resistant bacterial infection should be evaluated after which antibiotic selection should be made accordingly.

BACKGROUND AND STUDY AIMS: This study aimed to determine whether the use of i-scan endoscopy provides additional benefits to conventional endoscopy in the diagnosis of gastric precancerous lesions. PATIENTS AND METHODS: A total of 120 patients with histologically-verified intestinal metaplasia (IM) or atrophic gastritis (AG) were prospectively evaluated by esophagogastroduodenoscopy. Endoscopic examinations were performed using i-scan and high-definition white-light endoscopy (HD-WLE). The diagnostic yields of both techniques and the number of targeted biopsies per patient were compared. RESULTS: A total of 318 suspicious lesions were detected in 108 patients with i-scan (n = 186) and 81 patients with HD-WLE (n = 132). The diagnostic yields of i-scan and HD-WLE were 81.6% (98/120) versus 77.5% (93/120), respectively (p > 0.05). When only targeted biopsies were taken into account, the diagnostic yields of i-scan and HD-WLE were 89.8% versus 65.4%, respectively (p < 0.05). The mean number of biopsies per patient for i-scan and HD-WLE were 3.27 (393/120) and 7.3 (882/120), respectively (p < 0.05). The mean endoscopic procedure times were 16 and 17 min for i-scan and HD-WLE, respectively (p > 0.05). CONCLUSIONS: Although targeted biopsies with i-scan were not found to be significantly superior to either targeted or random biopsies with HD-WLE, the number of biopsies required to confirm these lesions was much lower.

PURPOSE: The aim of this study wasto investigate whole-breast imaging findings (mammography, ultrasonography (US), magnetic resonance imaging (MRI),clinical, and histopathological findings of primary neuroendocrine carcinomas of the breast (NEC) and neuroendocrine differentiated breast cancers (NEBC). METHODS: Patients withadiagnosis of breast cancer with histopathological neuroendocrine features between the years 2010 and 2021 were retrospectively screened.The lesions were divided into two main groups depending on staining with neuroendocrine markers (synaptophysin and chromogranin A). Those showing focal staining were categorized as NEBC while those with diffuse staining as NEC.The mammography, US, and MRI of the lesionswere reviewed in consensus by two breast radiologists in order to assess imaging featuresretrospectively according to the Breast Imaging Reporting and Data System (BI-RADS) 5th lexicon.The findings were compared with breast cancers without neuroendocrine features (BC-WNE) which were randomly selected from the same database. RESULTS: A total of 105 lesions [NEBC (n = 44), NEC(n = 11), BC-WNE (n = 50)] were evaluated.Patients with neuroendocrine tumors were older (p < 0.001) than those with BC-WNE. Compared with BC-WNE tumors, radiological findings typical of malignancy such as irregular shape [NEBC (7/20); NEC(3/7) vs BC-WNE (35/43); p < 0.001], spiculation [NEBC (2/20); NEC(0/7) vs BC-WNE (21/43); p < 0.001], architectural distortion [(NEBC (3/24); NEC(0/9) vs BC-WNE (31/50); p < 0.001)], calcification [(NEBC (6/24), NEC(0/9) vs BC-WNE (n = 27/50); p = 0.001)] on mamography, non-parallel orientation to skin [(NEBC (n = 17/29), NEC(n = 4/9), BC-WNE (n = 35/42); p = 0.008)], acoustic shadowing [(NEBC (n = 12/29), NEC(1/9), BC-WNE (n = 29/42); p = 0.009)], axillary lymphadenopathy [(NEBC(n = 3/30), NEC(n = 1/9), BC-WNE (21/50); p < 0.001)]on US were less common features of the neuroendocrine carcinomas of breast. Aside from shape features, there was no significant difference in contrast pattern (p = 0.866), kinetic curve (p = 0.454) and diffusion restriction (p = 0.242) on MRI. CONCLUSION: Characteristic malignant imaging features, including irregular shape, spiculated margins, suspicious calcifications, and posterior acoustic shadowing, are uncommon in neuroendocrine carcinomas of breast. These carcinomas tend to show more benign imaging features when compared with BC-WNE.

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a disease of unknown etiology, involving a chronic inflammatory process, characterized by noncaseating granuloma formation. IGM can mimic a tumor clinically and radiologically. Since we are a tertiary referral center, most of our patients (n = 56, 87.5%) are secondary admissions who have previously had antibiotics and steroid treatments; therefore, we accept these patients as resistant cases. Here, we aim to present our single-center series of 64 patients with resistant IGM who underwent methotrexate monotherapy. To the best of our knowledge, our study includes the highest number of patients described in the literature with IGM who have undergone this treatment. METHODS: This study included 64 patients, 56 of which were resistant cases, diagnosed with IGM between January 2013 and January 2020 at Istanbul University Cerrahpasa, Cerrahpasa Medical Faculty, General Surgery Breast Outpatient Clinic that were followed-up at least once. These patients were administered oral methotrexate monotherapy 15 mg/week for 24 weeks, and in relapsed cases, the treatment was up to 20 mg/week for 1 year. Folic acid 10 mg/week was given as a supplement to all patients. RESULTS: Complete recovery was observed in 52 (81.25%) of the 64 patients. Follow-up was discontinued by 4 patients. The dose was increased and the duration of treatment was extended up to 1 year when relapse was observed in 8 patients and complete response was then obtained in these cases. Only 3 patients (4.69%) experienced side effects and were switched to subcutaneous treatment due to nausea. CONCLUSION: Considering the high patient compliance, low recurrence, minimal side effects, and overall success of the treatment, we believe that methotrexate monotherapy may be used in treatment-resistant IGM patients and may also be the first choice for first-line treatment in the future.

OBJECTIVES: The aim of this study was to investigate the role of quantitative values obtained by superb microvascular imaging (SMI) and shearwave elastography (SWE) in the prediction of malignancy in intraductal papilloma-like lesions (IDPL). METHODS: In the study, 61 patients between the ages of 14 to 73 years (mean age 44) diagnosed with IDPL on ultrasound (US) examination between the years 2020 and 2021 were included. The B-Mode US findings (shape, margins, size, echo pattern, and accompanying ductal dilatation), SMI vascular index (SMIvi), E-mean, and SWE-ratio values were recorded. RESULTS: There was a statistically significant difference between malignant (n = 14) and benign (n = 47) groups in terms of symptoms (P = .005), size (P = .042), shape (P = .002), margins (P = .001), echogenicity (P = .023), microcalcifications (P = .009), SMIvi (P = .031), E-mean (P < .005), and SWE-ratio (P = .007). According to receiver operating characteristic (ROC) curve analysis, sensitivity, specificity, accuracy, area under the curve (AUC), positive predictive values (PPV), and negative predictive values (NPV) were 57.1%, 87.2%, 80%, 0.722, 57.1%, 87.2% for US; 71.4%, 49%, 55.7%, 0.692, 30.3%, 85.7% for SMIvi; 85.7%, 71%, 74%, 0.864, 46%, 94.3% for E-mean, and 50%, 75.4%, 83%, 0.707, 91.5%, and 50% for SWE-ratio, respectively. Best results were obtained when SMI and SWE values were used together, achieving a sensitivity, specificity, accuracy, AUC, PPD, NPD of 78.6%, 93.6%, 93.4%, 0.872, 91.7%, and 93.9%, respectively. CONCLUSIONS: The SMI and SWE examinations are successful in the differentiation of benign and malignant intraductal lesions. They complement each other and contribute to B-mode US in managing IDPLs especially when used together. Our study is the first to compare the quantitative data of SWE and SMI in the differentiation of IDPLs.

PURPOSE: The goals of this study were to report our clinical experience in a single center at a high-volume tertiary university hospital in Istanbul and to introduce a diagnostic algorithm based on a 5-year follow-up of 152 women with biopsy-proven idiopathic granulomatous mastitis (IGM). IGM is an uncommon, non-malignant, chronic inflammatory disease of the mammary gland with an unknown etiology. The symptoms, clinical presentation, and radiologic findings of IGM may resemble carcinomas. To our knowledge, this study comprises the largest series of IGM, especially with a 5-year follow-up, yet reported in the English literature. METHODS: The present study reported our single-center clinical experience at a tertiary university hospital in Istanbul, Turkey, and introduced a diagnostic algorithm using our treatment protocol based on a 5-year follow-up of 152 women with biopsy-proven IGM. Our database of 10 years' experience containing over 700 patients with IGM was evaluated. However, to assess recurrence and resistance to treatment, only the 152 patients with a long follow-up period of 5 years were included in the study group. The analysis included 152 women with biopsy-proven IGM who were treated between January 2009 and March 2014. The clinical data of the presentation, histopathology, and treatment modalities were analyzed by reviewing the medical records. RESULTS: Of the 152 patients diagnosed with granulomatous mastitis, 32 (21%) recovered by expectant management, while 14 (9%) responded to antibiotics, 65 (43%) received corticosteroids, 20 (13%) had antituberculosis medication, 16 (11%) underwent excision, and 5 (3%) responded to non-steroidal anti-inflammatory drugs. Fifty-one patients (33%) had recurrence; of these, 30 achieved a cure with second-line treatment, 16 underwent excision, and 5 achieved a cure with observation. CONCLUSION: IGM is a rare benign breast disorder, and clinicians need a high index of suspicion to diagnose it, as IGM can be mistaken for breast cancer. Unlike periductal mastitis, IGM does not evolve secondary to nicotine addiction and is typically seen in women of childbearing age with a recent history of pregnancy and lactation. The diagnosis can be challenging, and an evaluation with a multidisciplinary team is necessary. There is no consensus concerning the definitive treatment approach. We suggested a diagnostic algorithm in the present study, using our treatment protocol based on the 5 years' follow-up of 152 women.

INTRODUCTION: Extranodal lymphomas are commonly encountered in the gastrointestinal tract but lymphomas of colon and rectum are rare. Non-Hodgkin lymphoma is the most common type of colonic lymphoma and represents less than 0.5% of colorectal neoplasms. Chemotherapeutical agents are gateway to disease remission and sometimes cure in most patients but surgery may be necessary in emergent situations. CASE PRESENTATION: A 77-year-old male patient presented with abdominal discomfort, constipation, and obstructive defecation symptoms. Radiological imaging revealed a mass in the sigmoid colon extending towards the rectum. Colonoscopy was performed and biopsy of a nearly 10 cm ulcerovegetative lesion was obtained. Histological examination following biopsy revealed it to be a diffuse large B-cell lymphoma of the sigmoid colon. There was no indication for surgery and the patient was referred to medical oncology clinic for chemotherapy treatment. DISCUSSION: Non-Hodgkin lymphoma is a lymphoproliferative disorder with the diffuse large B cell lymphoma (DLBCL) being the most common subtype. The DLBCL subtype is rarely observed in the colon and rectum. Chromosomal abnormalities are involved in the pathophysiology and gene rearrangements lead to adjustments in lymphocyte function and differentiation. CONCLUSION: In this case report, we present a rare presentation of a Non-Hodgkin lymphoma presenting in the sigmoid colon. The disease can present with nonspecific symptoms and various imaging modalities along with histopathological evaluation is necessary for the correct subtyping of lymphoma. Chemoradiotherapy is key for treatment, and surgery is usually reserved for cases of obstruction, perforation, or bleeding.
RESUMEN
INTRODUCTION: Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory breast disease of unknown etiology, and erythema nodosum (EN) is a rare extramammary manifestation of this entity characterized by reddish, tender nodules of the lower legs. We aimed to investigate whether the association of IGM with EN has a role as a prognostic indicator. There are few case reports, and only 1 original article including 12 IGM patients with EN has been reported. METHODS: We present 43 women with IGM coexisting with EN and 43 with a diagnosis of IGM only, who were randomly selected from 610 patients for a control group. To the best of our knowledge, this paper comprises the first comparative study of the coexistence of IGM and EN to be reported in the literature. RESULTS: Our findings show that the association of IGM with EN indicates a more aggressive disease course. White blood cells, erythrocyte sedimentation rate, and C-reactive protein were significantly higher in the EN-positive group (P < .05). Arthralgia, breast feeding, fistula distribution and recurrence distributions were significantly higher in the EN-positive group (P < .05). CONCLUSION: Since fistula distribution and recurrence rates were higher in EN-positive group, association of IGM with EN may be an indictor of a worse prognosis. The present study highlights the importance of dermatological care. All physicians should not neglect questioning breast complaints in patients with EN since EN may be caused by IGM.
