Multiple Epidermal Inclusion Cysts of the Female Breast Coexisting With Fibroadenoma: A Case Report of an Incidental Finding.

This report discusses a case of a 27-year-old female with histopathological examination results of multiple epidermal inclusion cysts (EICs) coexisting with fibroadenoma without any involvement of breast skin. EIC should be considered as one of the differential diagnoses for benign breast lesions. Radiological evaluation, with surgical excision and histopathologic examination, remains the gold standard for the management of EIC. This report aims to increase the level of awareness on the existence of EIC in the breast parenchyma and the possibility of it coexisting with or arising from other benign breast lesions like fibroadenoma.

Usual breast lump with unusual features.

The co-existence of granulomatous mastitis and collagenous spherulosis in a breast lump is an uncommon finding. The awareness of cytomorphological features can help corroborate a cytological diagnosis. A palpable breast lump in an elderly female warrants urgent attention and fine needle aspiration is a rapid, reliable method of evaluation. An elderly female with a firm breast lump mimicking malignancy was subjected to fine needle aspiration cytology (FNAC). Smears showed ill-formed granulomas, inflammatory cells and homogeneous hyaline stromal globular elements intermingled with the benign ductal epithelial and myoepithelial cells.

An Interesting Case of Isolated Cysticercosis of Breast Masquerading as a Breast Lump in a Young Female.

Human cysticercosis can affect any tissue or organ in the body and may be asymptomatic or manifest clinical signs and symptoms depending on the area of the body where cysticerci are found. However, at the same time, the involvement of the breast by cysticercosis is an extremely rare phenomenon, with very few case reports published before. In this report, we present the case of a 26-year-old married woman who came with a history of painless swelling in the left breast.

Isolated cysticercosis of breast mimicking a mass lesion: A case report.

INTRODUCTION AND IMPORTANCE: Cysticercosis is a zoonotic disease caused by the larval form of Taenia solium. Its occurrence as a breast lump is rarely observed and therefore presents significant diagnostic challenges, especially in non-endemic regions. CASE PRESENTATION: A 25-year-old female patient presented with a lump in her left breast. The lesion was initially non-diagnostic on ultrasound and fine needle aspiration cytology. Excision biopsy of the cystic lesion was done, and histopathological examination confirmed it to be cysticercosis. Post surgery patient was given Albendazole, and she was asymptomatic during the 3 month follow up. CLINICAL DISCUSSION: This case highlights the disease's ability to present in atypical forms, such as a breast lump, and the importance of considering cysticercosis in differential diagnosis, especially in endemic regions. Ultrasonography remains the preferred initial diagnostic modality, and the role of FNAC and histopathology is crucial for confirmation. The case also emphasizes the need for heightened clinical suspicion, even when traditional risk factors like pork consumption are absent. CONCLUSION: This case emphasizes the importance of considering cysticercosis as a differential diagnosis for breast lumps, even with atypical presentation or in a non-endemic region. It highlights the need for greater awareness of this disease, stringent public health measures, and improved personal hygiene to combat its spread.

Infiltrating duct cell carcinoma in lactating adenoma: A rare case in pair.

Lactating adenomas, though considered being benign, sometimes turn out to be malignant. We are hereby presenting two cases of lactating adenomas which turned out to be harboring infiltrating duct cell carcinoma (DCC). Two lactating women with mass in the breast were referred from surgery for fine-needle aspiration cytology and biopsy. On histopathology, it was found that both had infiltrating DCC (either as collision tumor or as a malignant transformation of lactating adenoma). These cases point toward some association between lactating adenoma and DCC, however, small it may be. Therefore, any mass lesion in the breast should be followed up under strict vigilance for an early diagnosis and management of this deadly disease. A large sample size and elaborate study are required to frame its prognostic relevance. Like estrogen receptor and progesterone receptor, prolactin and prolactin receptor expression can be exploited for developing newer receptor-targeted therapy.

The Implementation of Diagnostic Assessment in Breast Lump Cases: A Cross-Sectional Study in Sragen, Indonesia.

Introduction Triple assessment, consisting of clinical breast examination, breast imaging, and fine-needle aspiration biopsy (FNAB), is the gold standard for breast lump diagnosis to avoid diagnostic errors. However, current diagnostic practices for breast lump cases in Indonesia are widely variable and evidence for triple assessment implementation is lacking. We aimed to explore the implementation of diagnostic assessments in breast lump cases, its influencing factors, and its association with diagnostic error. Methods This cross-sectional study consecutively recruited 364 females with breast lumps who underwent surgery in Soehadi Prijonegoro Public Hospital, Sragen, Indonesia. Data were retrospectively collected from patient's medical records. Diagnostic assessments were classified as single assessment with clinical breast examination, double assessment with clinical breast examination and breast ultrasonography (USG) or fine-needle aspiration biopsy (FNAB), and triple assessment. Diagnostic error was defined as a discrepancy between pre- and post-surgery diagnosis or repeated surgery without neoadjuvant chemotherapy. Factors associated with diagnostic assessment implementation, diagnostic error, and repeated surgery were analyzed using the chi-square test. Results The choice of diagnostic assessment was influenced by patients' age and health insurance (p<0.001). Triple assessment was only implemented in 21 (5.8%) breast lump cases. It was more frequently applied in patients ≥40 years (57.1%) and patients with contributory health insurance (76.2%). Diagnostic errors were observed in 84 cases (23.1%) and 47 patients out of them (47%) experienced repeated surgery. The implementation of diagnostic assessments was not associated with diagnostic error (p=0.257) but was significantly associated with repeated surgery in breast cancer (p<0.001). Repeated surgery rates were significantly lowered in cases receiving double assessment with FNAB (p<0.001). Conclusions The implementation of triple assessment in the local setting was very low. The choice of diagnostic assessment was influenced by patients' age and health insurance. Further, double assessment applying clinical breast examination and FNAB significantly decreased repeated surgery rates and thus may serve as an alternative to triple assessment in the limited resource setting.

Challenging Management of a Breast Mass: Case Report and Literature Review.

Idiopathic granulomatous mastitis (IGM) is a rare benign pathology of inflammation in the breast that commonly affects parous women of reproductive age and men although it is extremely rare. It has an unusual predilection for Hispanic women born outside of the United States, most notably in Mexico. Recently, this entity has been described more. However, the approach to management is still very controversial, and the approaches vary widely, although surgical approaches, including excision or mastectomy, have been less favored recently as a primary approach. Here, we present a case of a young female of reproductive age who presented initially with a suspicious breast lump diagnosed initially in the breast clinic as IGM and was referred to the rheumatology clinic for management with medical therapy.

Comparison of Wire and Non-Wire Localisation Techniques in Breast Cancer Surgery: A Review of the Literature with Pooled Analysis.

Background and Objectives: Wide local excision is a common procedure in the treatment of breast cancer. Wire-guided localisation (WGL) has been the gold standard for many years; however, several issues have been identified with this technique, and therefore, wire-free techniques have been developed. This scoping review synthesises the available literature comparing wire-guided localisation with the wire-free techniques used in breast-conserving cancer surgery. Materials and Methods: Multiple databases including Pubmed and MEDLINE were used to search articles between 1 January 2000 and 31 December 2022. Terms included "breast neoplasms", "margins of excision", and "reoperation". In total, 34/256 papers were selected for review. Comparisons were made between positive margins and re-excision rates of WGL with wire-free techniques including SAVI SCOUT, Magseed, ROLL, and RSL. Pooled p-values were calculated using chi-square testing to determine statistical significance. Results: Pooled analysis demonstrated statistically significant reductions in positive margins and re-excision rates when SAVI SCOUT, RSL, and ROLL were compared with WGL. When SAVI SCOUT was compared to WGL, there were fewer re-excisions {(8.6% vs. 18.8%; p = 0.0001) and positive margins (10.6% vs. 15.0%; p = 0.0105)}, respectively. This was also the case in the ROLL and RSL groups. When compared to WGL; lower re-excision rates and positive margins were noted {(12.6% vs. 20.8%; p = 0.0007), (17.0% vs. 22.9%; p = 0.0268)} for ROLL and for RSL, respectively {(6.8% vs. 14.9%),(12.36% vs. 21.4%) (p = 0.0001)}. Magseed localisation demonstrated lower rates of re-excision than WGL (13.44% vs. 15.42%; p = 0.0534), but the results were not statistically significant. Conclusions: SAVI SCOUT, Magseed, ROLL, and RSL techniques were reviewed. Pooled analysis indicates wire-free techniques, specifically SAVI SCOUT, ROLL, and RSL, provide statistically significant reductions in re-excision rates and positive margin rates compared to WGL. However, additional studies and systematic analysis are required to ascertain superiority between techniques.

A rare extrapulmonary presentation of tuberculosis: Breast tuberculosis.

Key Clinical Message: Breast abscess of long duration can be tubercular origin in both developing and developed countries despite its rarity. Abstract: A 34-year-old lady presented with painful lump on her breast for 2 months, which was diagnosed with mammary tuberculosis on basis of aspiration cytology and successfully treated with antitubercular drugs. Breast abscess of long duration may be tubercular etiology in both developing and developed nations.

Bilateral hydatid cyst of the breast: a case report and review of the literature.

Hydatid cyst disease is a parasitic infestation caused by the tapeworm Echinococcus granulosus. The incidence of the disease is 1-200 cases per 100 000. The usual presentation is the formation of fluid-filled cysts in the liver or lungs and, less commonly, in the brain. The breast is a rare site of presentation for this disease. An isolated hydatid cyst in the breast is very rare, even in endemic regions, occurring in only 0.27% of all hydatid cases. Although these cases are very rare, they should be considered severe. A hydatid breast cyst may mimic a fibroadenoma, phyllodes tumor, chronic abscess, or even carcinoma. Therefore, a high incidence of misdiagnosis may occur. Preoperative diagnosis can be made using needle aspiration and imaging facilities such as breast ultrasonography, mammograms, and computerized topographic images. Nevertheless, in most cases, the final diagnosis cannot be made until the pathological report is obtained postsurgery. This paper reports the first case of a bilateral hydatid cyst of the breast that was diagnosed preoperatively by radiological facilities. We present the patient history, physical examination, and investigations, discuss the risk factors, and present our treatment plan.

Comparative Accuracy and Complications of Palpation-Guided Versus Ultrasound-Guided Core Needle Biopsy of Palpable Breast Lumps in Ahmadu Bello University Teaching Hospital, Zaria.

Background: Breast lumps are a common complaint by women. Palpable breast lumps are accessible to core needle biopsy (CNB) with the aim of obtaining tissue for histologic diagnosis. CNB is achievable either by palpation guidance or image guidance. The superiority of either technique in returning an accurate diagnosis has not been demonstrated in our centre. Aim: This study aimed to compare the diagnostic accuracy and complications of palpation-guided versus ultrasound-guided CNB techniques in palpable breast lumps. Materials and Methods: This was a randomised, controlled, comparative study. Consenting patients were randomised into either a palpation-guided or an ultrasound-guided group. All patients subsequently had open surgical biopsy, which represented the control group. Data analysis was done using SPSS, version 21. Results: Each CNB group had 40 patients. In the palpation-guided group, 24 (54.55%) lumps were benign and 13 (29.55%) were malignant, whilst seven (15.90%) were inconclusive. In the ultrasound-guided group, 31 (65.96%) lumps were benign and 15 (31.91%) were malignant, whilst one (2.13%) was inconclusive. The sensitivity and specificity for palpation-guided CNB were 92.9% and 100%, respectively. The sensitivity and specificity for ultrasound-guided CNB were 100% each. There was no statistically significant difference in sensitivity between the two groups (P value of 0.4828). One patient (2.5%) in the ultrasound-guided CNB group had a hematoma. Conclusions: This study has shown that CNB has high diagnostic accuracy and low complications in the management of breast lumps, either by palpation-guided or ultrasound-guided techniques. There was no significant difference in accuracy or complications of CNB using either technique.

Assessing the accuracy of the International Academy of Cytology Yokohama System for reporting breast fine needle aspiration biopsy cytology at a Vietnamese oncology centre.

BACKGROUND: Fine needle aspiration biopsy (FNAB), accompanied by classification systems for cytology, can offer a cheap and convenient option for the diagnosis of breast cancer in women with suspicious breast lumps. In this study, we aimed to assess the accuracy of the International Academy of Cytology (IAC) Yokohama system in a Vietnamese oncology centre. METHODS: A retrospective cross-sectional study was conducted from November 2021 to April 2022 at Vietnam National Cancer Hospital. We included patients with full hospital records regarding breast lesions for which FNAB was indicated. A total of 803 patients' FNAB specimens were assessed according to the IAC Yokohama system. The basic characteristics were summarised using the appropriate summary measurements. The risk of malignancy (ROM) was calculated for each classification category. RESULTS: The median age was 42.7 years (range: 14-85). The mean size of the lesions was 17.9 mm (range: 4-123 mm). We had 215 histopathological reports. The most common benign and malignant diagnoses were fibroadenoma and invasive carcinoma, respectively. The ROM for categories II, III, IV, and V was calculated as 3.4%, 37.5%, 95%, and 99.2% respectively. The sensitivity, specificity, positive predictive value, and negative predictive value were 96.4%, 97.2%, 98.5%, and 93.2%, respectively. CONCLUSION: The IAC Yokohama system offers a good option with which to predict underlying breast pathology using a simple and cheap procedure. However, pathologists require continuous training to ensure accurate interpretation of the slides.

Radiological Evaluation of a Malignant Gastrointestinal Stromal Tumor in a Female Patient With the Coincidental Detection of Primary Breast Cancer: A Case Report.

Gastrointestinal stromal tumors (GIST) are a rare and unique group of mesenchymal tumors arising from the gastrointestinal tract, omentum, mesentery, and retroperitoneum. Though they have certain typical radiological features that can differentiate them from epithelial tumors, it is often difficult to differentiate them from other non-epithelial tumors. Their features also vary depending on their size, site of origin, etc. When differentiation from other mesenchymal tumors on histopathology is difficult, receptor tyrosine kinase (C-KIT proto-oncogene/CD117) and gastrointestinal stromal tumor (GIST-1) discovered on GIST1 (DOG-1) expression are confirmatory. The concurrent presence of other primary cancers with GISTs has been described in the literature, among which most have been of gastrointestinal origin. Few cases of primary breast cancer in GIST have been described. Lymph nodal metastasis is rarely encountered in GIST, and metastasis to the breast is even rarer. We present a case of a 39-year-old female with non-specific symptoms who was referred for ultrasonography (USG) and computed tomography (CT) that showed a small intestinal GIST along with a breast lump and axillary lymphadenopathy that were labeled as metastases from the GIST on frozen sections; however, they were later diagnosed as primary breast cancer with axillary metastases on the histopathology and immunohistochemistry of the excision biopsy specimens post-surgery. The patient underwent surgical resection and chemotherapy.

Clinically guided core biopsy and cutaneous punch biopsy in the evaluation of breast lesions: a necessary test or an obsolete skill?

OBJECTIVE: The vast majority of breast cancers are diagnosed via image-guided procedures yet despite significant advances, imaging does not identify all breast malignancies. Clinically suspicious breast lesions with normal breast imaging remain a cause for concern. The aim of this study is to determine the diagnostic value of clinical core and cutaneous punch biopsies in the diagnosis of breast malignancy in clinically suspicious lesions with normal breast imaging. METHODS: All patients with suspicious clinical breast findings and normal imaging who underwent a clinical core and/or cutaneous punch biopsy from 2012 to 2019 were reviewed retrospectively. Patients with subsequent breast malignant diagnosis were analysed. RESULTS: A total of 283 biopsies (166 clinical core, 117 cutaneous punch) performed over the 7-year period were included in the analysis. A total of 263/283 (93%) yielded a benign outcome. A total of 2/283 (0.7%) yielded B3 lesions (probably benign). These lesions were benign on final surgical excision. A total of 18/283 (6.3%) yielded a malignant histopathology. Sixteen out of 18 were cutaneous punch biopsies, and 2/18 were clinical core biopsies. A total of 14/18 patients presented with nipple changes, while 4/18 had a palpable area of concern. Histopathological analysis demonstrated Paget's disease of the nipple in 8/18, invasive carcinoma in 9/18 out of which two represented a recurrence of breast malignancy. Cutaneous squamous cell carcinoma was diagnosed in 1/18. CONCLUSION: Clinical core and cutaneous punch biopsies remain a valuable tool in the diagnosis of breast cancer particularly in the management of clinically suspicious radiographically occult malignancies.

Granulomatous mastitis (GM) in a young woman with a previous history of prolactin-secreting PitNET and actual normal prolactinemia.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory condition of the breast. IGM is a benign condition, and is more typical in women of child-bearing age, with a recent history of pregnancy and breast feeding. Its clinical presentation can mimic inflammatory breast cancer or breast abscess. The etiology of IGM is not well defined, but proposed to be a localized immune reaction to the breast tissue without the presence of an underlying infectious condition. Here we report a case of a healthy 35-year-old female, with no story of pregnancy and lactation, who presented with sudden left breast lump, swelling and pain. She underwent first diagnostic ultrasound of the affected breast, then breast MR imaging was performed. A biopsy of the lesion was obtained, which revealed chronic granulomatous inflammation, confirming the diagnosis of GM. Furthermore, the patient was found to have had hyperprolactinemia secondary to a prolactinoma of the pituitary gland (PitNET) many years before, during her 20s, for which she had been treated with surgery.

Hidden Intruder: A Rare Encounter of Dirofilaria Masquerading as a Breast Lump.

Dirofilaria, commonly known as heartworm, is a parasitic nematode that primarily infects canines. However, human infections have been reported and can present as subcutaneous nodules in different parts of the body. We present a case of a 43-year-old female who presented with a breast lump that was ultimately diagnosed as a Dirofilaria infection, a rare occurrence in humans. This case report shows that considering parasites in unusual presentations is of utmost importance, especially in regions known to have a high prevalence of such infections.

Fibroadenoma of the breast; incidence of malignancy and indicators for surgical intervention: An analysis of 1392 patients.

BACKGROUND: Fibroadenomas are common among young females. The size of the lesion used to be an indication for further assessment or excision. With arising of the watch and see proponents, criteria for selecting patients are important to establish. METHODS: This is a retrospective study of a prospectively maintained database where all patients having the clinical/radiological provisional diagnosis of fibroadenoma and attending our center - from January 2008 to March 2020 - were enrolled. The primary outcome was the incidence of malignancy and the secondary outcomes were the correlation of malignancy-risk with epidemiologic and radiologic criteria. RESULTS: The study enrolled 1392 patients. The mean age of the patients was 35.7 + ∕- 13.1 years. The median of the longest diameter of the detected breast lesions was 25 mm. The incidence of malignancy was 188 (13.5%). The size of the lesion measured by largest diameter was insignificant (p = 0.99), while the patients' age, marital status, and imaging criteria as measured by BIRADS score were significant (<0.001). CONCLUSION: Approaching patients with the age above 35 or with BIRADS 4 provisionally diagnosed with fibroadenomas should be cautious with biopsy and short-term follow-ups The size of the tumor alone should not be used as an indication for surgical intervention.

Fibroadenoma: a guide for junior clinicians.

Fibroadenoma is the most common cause of benign breast lumps and is typically seen in women under the age of 40 years. Fibroadenomas are classified as simple, complex, giant, myxoid or juvenile. They present as smooth, rubbery, mobile masses on palpation. Ultrasonographic and mammographic features typical of fibroadenomas include solid, round, well-circumscribed masses, with or without lobulated features. They are predominantly treated conservatively although clinical pathways recommend referral for triple assessment. Surgical intervention is indicated by the presence of one or more of the following features: the presence of symptoms, a diameter greater than 2 cm, rapid growth rate, complex features, disease recurrence or patient anxiety.

A Case of a Female Patient Presenting With Idiopathic Granulomatous Mastitis With Superimposed Enterococcus Avium Infection.

Idiopathic granulomatous mastitis (IGM) is defined as an uncommon, benign, chronic inflammatory disease of unknown etiology that affects the breast and can mimic breast cancer. It usually manifests as a solid, ill-defined breast lump in postpartum women of reproductive age. Furthermore, because it lacks a particular radiographic finding, core biopsy and histology are the only ways to make a conclusive diagnosis. There is no agreement on the best way to treat IGM. Ideally, a multidisciplinary approach should be used to weigh the benefits and drawbacks of each treatment option, with options such as observation, antibiotics, surgery, and medication therapy being examined (steroids and immunosuppressants). In this report, we review a case of a patient who had IGM with superimposed Enterococcus avium infection. To our knowledge, such a report is considered unprecedented in the Middle East. A literature review on IGM will be presented, as well as the clinical presentation, association with bacterial infection, treatment, and pathological and radiographic findings.

Palpable breast lumps: An age-based approach to evaluation and diagnosis.

A palpable breast lump is a common presentation of breast disease to a general practitioner. Fortunately, investigation of most of these lumps will lead to a benign diagnosis. It is essential to have a clear and systematic approach when investigating a palpable breast lump to avoid over investigation with the resultant increase in healthcare cost and anxiety. This article will discuss an approach to evaluating and diagnosing a palpable breast lump in the primary care setting.
