Gastric trichobezoar and Rapunzel syndrome: case report of a very rare condition.

Background: Rapunzel syndrome is a rare trichobezoar variant extending from the gastric cavity into the small bowel. Case description: We report the case of a 22-year-old woman who presented with epigastric pain, nausea, and loss of appetite within the preceding five weeks. She had a palpable mass in the epigastric area with mild localized tenderness. Her abdominal computed tomography scan showed a distended stomach and duodenum, with a heterogeneous solid material, suspicious for a bezoar. Upper gastrointestinal endoscopy revealed a large, densely packed trichobezoar occupying the gastric cavity and extending through the pylorus. Endoscopic removal of the bezoar was unsuccessful. The patient underwent a 6cm-long gastrotomy, and the 150cm-long bezoar, extending from the stomach to the jejunum, was uneventfully removed. The patient was referred postoperatively to a dietitian and psychiatrist for management of her trichotillomania and trichophagia. Conclusion: Trichobezoars are commonly found in young females with a history of trichotillomania and trichophagia and are associated with psychiatric disorders. HIPPOKRATIA 2023, 27 (1):25-27.

Seasonal variation in breast cancer incidence. Circumstantial or default event?

UNLABELLED: It has been previously suggested that seasonality in the detection of breast cancer is mostly seen in countries with distinct climatic variations. Patient characteristics and delays have been implicated in the etiology of peak presentation. Seasonality has been more marked in premenopausal women, while delays have been attributed to both patients and health care systems. PATIENTS: A total of 1,411 women who presented with breast cancer to our department were analyzed according to their age, menopausal status, site, stage, grade, ER and PR status, c-erb-2 and Ki-67 (412) during the year. RESULTS: The seasonal variation was statistically significant, but no statistically significant differences were established between corresponding subgroups. CONCLUSION: The seasonal variation most probably reflects temporal, psychosocial and behavioral patterns in the Greek female population. Since we do not have the ability to recognize the actual onset of any cancer and then correlate it with various different independent factors we can not correlate its influence on survival or biological marker manifestations.

Retroperitoneal sarcomas: from diagnosis to treatment. Case series and review of the literature.

BACKGROUND: Retroperitoneal sarcoma is a rare malignancy arising from mesenchymal cells, most commonly presented as an abdominal mass and is associated with poor prognosis. The most effective treatment modality for retroperitoneal sarcomas is complete surgical resection, including sometimes adjacent organs infiltrated by the tumor. Radiotherapy is frequently applied and has shown some benefit, while the role of chemotherapy and molecular-targeted agents is still not clear. Local recurrence is common for retroperitoneal sarcomas and still remains the main cause of death. The major factors associated with the overall survival are tumor grade, histological subtype, complete macroscopic excision and multifocality. AIM: To report our experience via the presentation of patients with retroperitoneal sarcomas managed in our department during the period 2014-18; and to review the current literature. PATIENTS AND METHODS: Eight patients appeared with chronic non-specific complaints including abdominal distension and changes in bowel or bladder habit, while one patient presented with acute abdominal pain due to mass rupture. All of the patients underwent surgical resection of the tumor. RESULTS: Among the patients, seven were operated for primary disease and one only for recurrent. The most common histologic type was liposarcoma (well-differentiated, dedifferentiated), found in five patients; followed by leiomyosarcoma found in two cases. Fibrous histiocytoma was found in only one case. The masses were removed with macroscopically clear margins (R0 and R1 resections) in four cases. In five patient cases adjuvant therapy was required. Three patients are still alive and free of disease. CONCLUSIONS: Retroperitoneal sarcomas present to be a therapeutic challenge based on their location, their extent at the time of diagnosis and the high risk of local recurrence or distant metastasis. Their management requires a multidisciplinary approach, with the surgical resection remaining the mainstay of curative treatment, combined with surveillance for early detection of recurrence or metastases.

Impact of breast cancer surgery on the self-esteem and sexual life of female patients.

Patient satisfaction with cosmetic outcome and the psychological impact of breast cancer surgery were evaluated. A total of 207 patients with primary breast cancer, treated with either breast-conserving surgery (n = 83), modified radical mastectomy without reconstruction (n = 108), or mastectomy with delayed breast reconstruction (n = 16) rated their cosmetic outcome and satisfaction following surgery, and the impact of surgery on their self-esteem and sexual life, by questionnaire. Patients undergoing breast-conserving surgery were most satisfied with their surgery and body image, followed by those treated with mastectomy with delayed reconstruction. Although diagnosis of breast cancer had a negative impact on the psychology of all patients, those undergoing breast-conserving surgery or mastectomy with delayed reconstruction were more satisfied and reported a lower impact on their self-esteem and sexual life versus those who only had mastectomy. Diagnosis of breast cancer has a negative psychological impact on the patient, but the type of surgery has a significant role in post-operative self-esteem and sexual life.

Paraffinomas of the breast or oleogranulomatous mastitis-a rare entity.

Breast augmentation with the injection of a high-viscosity fluid has been practiced in the past, especially in Asia, resulting in most cases in different varieties of paraffinoma, alternatively known as oleogranulomatous mastitis, a complication of a 'foreign body' reaction type. We report our series of four consecutive cases of destructive paraffinomas that occurred in female patients who had had paraffin injection for cosmetic reasons. Complications due to paraffinoma reactions of breast tissue and skin, as well as progression of the disease and treatment of our patients, are presented here, together with a review of the relevant literature.

Surgical management of nipple discharge.

PURPOSE: Nipple discharge is reported in 2.5-3% of women with breast carcinoma. Breast carcinoma is found in approximately 8% of surgically treated patients presenting with bloody nipple discharge (ND). METHODS: In the present study 110 women with ND as a presenting symptom were examined. The discharge was spontaneous in 76 and elicited in 11 patients. RESULTS: After surgical intervention benign breast disease was found in 85% of patients. Thirteen women (15%) were found to have malignancy and underwent additional surgery. Cytology of the discharge was positive or suspicious for malignancy in only seven out of 13 patients found to have in situ or invasive carcinoma. CONCLUSION: Women with spontaneous, single duct ND, especially when it is darkish or bloody, should have cytological examination of the fluid and mammography according to their age or additional clinical findings. Most of them will require a microdochectomy, as the possibility of finding a carcinoma among those women is between 10-15%. However, single duct papilloma is the most common cause of bloody discharge.

Wire localisation biopsy of non-palpable breast lesions: reasons for unsuccessful excision.

Surgical excision following needle-wire localization of nonpalpable, mammographically detected breast lesions is a very valuable diagnostic and therapeutic procedure. No further treatment is usually required after establishing an accurate histological benign diagnosis of indeterminate lesions on preoperative assessment. On the other hand, ductal carcinoma in-situ (DCIS) and early invasive cancer, properly excised, may sometimes require further management depending on specific histologic findings. An uncommon problem of this procedure is the failure to identify, localize or excise the breast lesion. In this review article, factors that contribute to the failed needle localization procedure are presented.

Open surgical biopsy for nonpalpable breast lesions detected on screening mammography.

The aim of this retrospective clinical study was the analysis of histologic findings of nonpalpable breast lesions managed by open surgical biopsy. A series of 630 women underwent 664 preoperative localizations of nonpalpable, mammographically detected breast lesions during the last 10-year period. Indications for biopsy were (1) clustered microcalcifications, (2) solid mass, and (3) radiologic parenchymal distortion. The lesions were localized preoperatively using hook-wire methods, and all biopsies were performed under general anesthesia. Histopathology revealed carcinoma in 172 (25.9%) cases; noninvasive in 114 (66.3%) cases and infiltrating in 58 (33.7%) cases. The highest malignancy rate was found in cases with microcalcifications (112 carcinomas out of 323 cases, 34.7%). Lymph node invasion was present in 25% of patients with invasive cancers. The hook-wire localization of nonpalpable breast lesions is a simple, accurate and safe method for detection of early breast cancers. Frozen section is feasible and accurate in the majority of these lesions, and therefore, diagnostic and therapeutic one-step surgical procedures could be performed.

Mondor's disease of the breast: is there any relation to breast cancer?

Ten cases of Mondor's disease of the breast (9 females, 1 male) are described. The diagnosis was based mainly on clinical examination, while breast imaging, used in five cases, was complementary. Most of our cases (9) had complete restoration of the thrombosed subcutaneous breast vein, either spontaneously (4), or after anti-inflammatory medication (5). Only one of our patients had surgical management (vein excision) due to delayed remission. None of our cases was related to breast cancer.

Development of early malignant bilateral breast disease in relation to antidepressant treatment.

The aim of this study is to present two rare cases of young female patients who were under antidepressant medication and developed bilateral breast disease; histology confirmed the noninvasive, malignant nature. The role of that type of agents in the breast pathology is briefly discussed, based on the data of the current literature.

Metastatic intramammary lymph nodes as the primary presenting sign of breast cancer.

Intramammary lymph nodes (IMLNs) are not uncommon, and are likely to be more frequently identified with the wider use of mammography and breast ultrasound. IMLNs could be invaded by breast cancer influencing the prognosis and the management of patients. The aim of this study is to present the very rare phenomenon of metastatic involvement of these nodes from an occult breast cancer.

Autoimmune thyroid disease in women with breast carcinoma.

AIMS: Estimation of prevalence of autoimmune thyroid disorders in Greek breast cancer patients (prospective study). METHODS: The prevalence of autoimmune thyroiditis was estimated in 310 Greek breast cancer patients, in 100 women with benign breast disease and in 190 women without any breast disease, by submitting them to clinical examination, ultrasound thyroid evaluation, serum thyroid antibody determination and fine needle aspiration (FNA) of the thyroid gland. RESULTS: Autoimmune thyroiditis was found in 136/310 (43.9%) breast cancer women: 95 were diagnosed by positive autoantibodies, 19 had positive FNA findings and 22 had both positive autoantibodies and positive FNA findings. In 117 cases, thyroid autoantibodies were positive (37.7% whereas the control groups had respective rates of 19% and 18.4% autoantibody positivity). CONCLUSIONS: There is evidence of high incidence of autoimmune thyroiditis in Greek breast cancer patients, increasing in relation to cancer stage.

Use of artificial neural networks (computer analysis) in the diagnosis of microcalcifications on mammography.

INTRODUCTION/OBJECTIVE: The purpose of this study was to evaluate a computer based method for differentiating malignant from benign clustered microcalcifications, comparing it with the performance of three physicians. METHODS AND MATERIAL: Materials for the study are 240 suspicious microcalcifications on mammograms from 220 female patients who underwent breast biopsy, following hook wire localization under mammographic guidance. The histologic findings were malignant in 108 cases (45%) and benign in 132 cases (55%). Those clusters were analyzed by a computer program and eight features of the calcifications (density, number, area, brightness, diameter average, distance average, proximity average, perimeter compacity average) were quantitatively estimated by a specific artificial neural network. Human input was limited to initial identification of the calcifications. Three physicians-observers were also evaluated for the malignant or benign nature of the clustered microcalcifications. RESULTS: The performance of the artificial network was evaluated by receiver operating characteristics (ROC) curves. ROC curves were also generated for the performance of each observer and for the three observers as a group. The ROC curves for the computer and for the physicians were compared and the results are:area under the curve (AUC) value for computer is 0.937, for physician-1 is 0.746, for physician-2 is 0.785, for physician-3 is 0.835 and for physicians as a group is 0.810. The results of the Student's t-test for paired data showed statistically significant difference between the artificial neural network and the physicians' performance, independently and as a group. DISCUSSION AND CONCLUSION: Our study showed that computer analysis achieves statistically significantly better performance than that of physicians in the classification of malignant and benign calcifications. This method, after further evaluation and improvement, may help radiologists and breast surgeons in better predictive estimation of suspicious clustered microcalcifications and reduce the number of biopsies for non-palpable benign lesions.

Factors affecting axillary lymph node metastases in patients with T1 breast carcinoma.

The purpose of this study was to determine factors associated with the incidence of axillary lymph node metastases (ALNM) in T1 tumors and cases in which axillary dissection could be omitted. Data from 195 patients with T1 primary invasive breast cancer (size < or = 2 cm) who underwent either mastectomy or wide local excision of the tumor and axillary dissection were reviewed. ALNM was found in 59 of 195 patients with T1 tumors (30.3%). Tumor size was found to be the only independent predictor of ALNM, having a directly analogous relationship with the probability of invaded nodes: T1a (< or = 5 mm) tumors had 0 per cent ALNM, whereas T1b (5 mm < T1b < or = 10 mm) and T1c (10 mm < T1c < or = 20 mm) tumors had 25.7 per cent and 33.8 per cent ALNM respectively. Among the other factors studied (patient age, tumor site, hormone receptor status, histologic type, and grade of the tumor) only the histologic grade of the tumor cells appeared to correlate with the incidence of lymph node involvement, but this was not statistically significant. In conclusion only tumor size has statistically significant correlation with the incidence of ALNM. Routine axillary dissection could be omitted only in patients at minimal risk of ALNM (ductal carcinoma in situ and T1a) and when treatment decisions were not influenced by lymph node status (e.g., elderly patients with clinically negative axilla). Axillary dissection (at least levels I and II) should be performed in all cases with primary invasive breast cancer with tumor size > 5 mm.

Missed cancers on mammograms: causes and measures of prevention.

Mammographically missed breast cancers remain a major medical and legal issue. In order to clarify causes and methods of the limitations, we present the experience of our Unit on this field. During the years 1999 and 2000, 319 breast cancer patients were admitted for surgical treatment to our Unit. Their files were reviewed in order to identify cases with mammography-related delayed diagnosis. Thirty-three cases of mammographically missed cancers were found (10.3%). The usual reasons for the delayed diagnoses were: retrospectively visible cancers, in benign looking lesions no further action was taken, and lesions with a rather malignant appearance were reported as benign. Missed cancers could be reduced by simple measures such as the full assessment of breast patients with clinical, radiologic, and cytologic-histologic evaluation, the double screening of mammograms, and improvement of the mammographic equipment and technique.

Fibroadenomas of the breast: is there any association with breast cancer?

PURPOSE: The experience of our Breast Unit in the diagnosis and treatment of fibroadenomas is presented in this retrospective study, focusing specifically in cancer development within these common benign tumors of young age. MATERIAL-METHODS: 310 women with histologically verified breast fibroadenomas who had surgical management in our Unit over the last 14 years were included in the study. RESULTS: Most of them (n: 255) presented with palpable lesions and had triple assessment preoperatively, while the remaining 55 had nonpalpable lesions and underwent needle-wire localization biopsies. Nine cases had cancer development, usually in situ, within the fibroadenomas (2.9%). CONCLUSION: Coexistence of fibroadenomas and breast cancer is relatively rare, but it should not be ignored by breast surgeons, and patients should be properly informed.

Carcinosarcoma of the breast: report of two cases.

Carcinosarcoma is a rare, malignant tumor of the breast, consisting of intraductal or infiltrating carcinoma contiguous or subtly merged with a highly cellular, mitotically active pleomorphic spindle cell stroma (sarcoma). It is a form of the metaplastic mammary carcinomas and it is probably derived of myoepithelial cells. We report two cases of breast carcinosarcoma in two white women. The patients, following a frozen section positive for malignancy, had had a modified radical mastectomy. Paraffin sections and positive immunohistochemical cell staining (in our first case) confirmed the diagnosis of carcinosarcoma. This tumor should be distinguished from other forms of metaplastic carcinomas because it is very aggressive and has an ominous prognosis.

Granular cell tumor of the breast: a rare lesion resembling breast cancer.

Granular cell tumor (GCT) is an uncommon, usually benign tumor that occasionally involves the breast. It is possibly of neural origin (Schwann cells) and usually occurs in premenopausal black women. Physical examination, mammographic, ultrasonographic findings and pathologic examination may suggest breast malignancy. Positive immunohistochemical staining of the cells for S-100 protein, NSE, and CEA is indicative of GCT. Surgical treatment of choice is wide local excision. We report a case of granular cell tumor of a female breast. A 52-yr-old white woman had a palpable mass close to her right axilla. Computer tomography (CT) showed a 3.74 cm mass in the mammary tail of Spencer. The findings were suspicious for malignancy and the lesion was widely resected. Pathologic examination showed granular cell tumor.

Breast cancer in ectopic breast tissue.

Ectopic breasts usually develop along the mammary ridges. Their incidence has been reported as up to 5-6%. Development of malignancy is rare. We report three cases of postmenopausal female patients with breast cancer which developed in the axillary accessory breast. They were all successfully treated by surgery and adjuvant therapy. A review of the literature on the incidence and pathology of ectopic mammary tissue is also presented.

Gastrointestinal carcinoid tumors: 10-year experience of a general surgical department.

Gastrointestinal (GI) carcinoids are rare neuroendocrine tumors of great interest because of the multitude of the peptide hormones they produce, their clinical manifestations, the carcinoid syndrome they cause, their biologic behavior, and the methods of their surgical and adjuvant treatment. In this retrospective study, 25 patients with carcinoid tumors admitted and surgically treated in our department during the last 10 years are presented. Most of the cases were located in the ileum (n = 8) and appendix (n = 12). The remaining cases were located in the rectum (n = 2), stomach (n = 1), duodenum (n = 1), and ileocecal valve (n = 1). After tumor resection and postoperative treatment, mainly with somatostatin analogs, our patients had a good recovery, and only five deaths were reported during follow-up. Carcinoids, despite the fact that they are usually silent and diagnosed with advanced stage, have good prognosis and offer, after effective treatment, long survival.
