Adenomyoepithelioma of the breast is an uncommon tumor characterized by the presence of both epithelial and myoepithelial cells; its first full description was published in 1970 by Hamperl. A 45-year-old woman presented a left breast lump that had been palpable for 4 weeks. There was no family history of breast cancer. Neither axillary nor supraclavicular lymph nodes were palpable. Craniocaudal mammography showed a 1.6 cm, well-defined nodule with several punctate intranodular calcifications in the subareolar region of the left breast. Color Doppler sonogram showed an ovoid, well-defined, homogeneous hypoechoic subareolar nodule with prominent peripheral vessels in the 6 o'clock position of the left breast. Operation was arranged and intraoperative frozen section examination revealed proliferation of round, oval or tubular glandular elements with intervening islands and bands of polygonal myoepithelial cells. Adenomyoepithelioma of the breast was the impression. Wide excision with adequate removal of the tumor and preservation of the left breast contour was successfully achieved. The diagnosis of adenomyoepithelioma of the breast was confirmed by immunohistochemical studies.

Adenomyoepithelioma of breast is a rare, benign proliferative tumor formed of proliferationof myoepithelial cells surrounding small epithelium lined spaces. We present two cases ofadenomyoepithelioma of the breast. The irst case was of a 23-years-old female with right breast lump and the second of a 41-year-old female with left breast lump. No patient had prior, coexistent carcinoma of either breast. None had any family history of breast cancer either. Excisional biopsy, Hematoxylin and Eosin staining and immunohistochemistry with S100 were performed. The pathological diagnosis was adenomyoepithelioma.

Abstract Background Breast cancer is the leading cause of cancer death in women, and most breast cancer related deaths are due to metastasis. Urinary bladder metastasis from breast cancer is rarely reported in the literature. Case presentation We report a case of a 77-year-old female with history of left breast cancer, who presented a thickening of the bladder wall at pelvic ultrasound. Biopsy confirmed that the origin was lobular carcinoma of breast origin. The patient received chemotherapy, but the clinical course of the patient was very aggressive and she died one year later. Conclusion Bladder metastasis from breast cancer is rare, but the literature reveals an increase in such occurrence over the last few years. Pathologic diagnosis relies on immunohistochemical studies. Chemotherapy and hormonal treatment represent the standard therapy, with radiotherapy being used only to control bladder bleeding. The prognosis is usually poor.

Primary neuroendocrine carcinomas of the breast are rare of all breast carcinomas. They may be welldifferentiated, poorly differentiated, or invasive breast cancers with neuroendocrine differentiation. They are staged and treated similarly to conventional breast cancer. Herein, we report a case of invasive ductal carcinoma with neuroendocrine differentiation of the breast in a 73 years female with a history of breast lump initially in the lower inner quadrant of left breast and a month later, similar lump at the same site in right breast. Patient underwent Modified Radical Mastectomy bilaterally followed by adjuvant chemotherapy based on Carboplatin and Etoposide regimen.

Abstract Objectives Adenomyoepithelioma of the breast is an uncommon biphasic breast lesion characterized by a cytologically bland epithelial and myoepithelial proliferation. It is often considered benign and thought to represent a variant of intraductal papilloma. However, rare cases of adenomyoepitheliomas have been reported to show malignant transformation. Features that favor malignancy include increased mitoses, necrosis, atypia, cellular pleomorphism, and infiltrative borders. Most reported cases of malignant adenomyoepithelioma demonstrate carcinomas arising in a benign adenomyoepithelioma. Methods A 74-year-old woman presented to the hospital with an 8-month history of a palpable right breast mass. Mammogram demonstrated an irregular marginated mass, and a needle core biopsy of the mass showed atypical sclerosing adenosis. A lumpectomy revealed a firm, tan-white, ill-defined 2.7-cm mass abutting the anterior and posterior margins. Results Histologic examination showed an infiltrative proliferation of epithelial-lined tubules surrounded by myoepithelial cells with clear cytoplasm. There were focal areas of hypercellularity with marked cytologic atypia in both the epithelial and myoepithelial components. Focal necrosis and increased mitoses (12/10 HPF) were also identified. On immunohistochemical studies, the epithelial cells were positive for CK7 while the myoepithelial cells were highlighted by p63, SMMHC, SMA, and CK5/6. Ki-67 showed an increased proliferative index (35%). ER, PR, and HER-2 immunostains were negative. The overall histologic and immunohistochemical findings support a diagnosis of malignant biphasic adenomyoepithelioma. No in situ carcinoma was identified. After the diagnosis was reported, a follow-up reexcision with axillary sentinel lymph node excision was performed. Both specimens were negative for malignancy. Conclusion Malignant adenomyoepithelioma of the breast is an uncommon entity and it is strongly associated with local recurrence and distant metastases. Awareness of its distinctive histologic and immunohistochemical features will be helpful in initiating the appropriate medical management for patients with this entity, which is crucial for improving prognosis and overall survival.

A 42-year-old woman, with no history of autoimmune diseases or risk factors for cancer, sought a private medical clinic for undergoing breast imaging tests, noticing the presence of a solid nodule with indistinct margins — BI-RADS 4 — in the left breast. An ultrasound-guided core biopsy was performed and complemented by histopathological and immunohistochemical studies, confirming the diagnosis of primary small B-cell MALT lymphoma. After treatment with radiotherapy, the patient evolved with remission, maintaining annual follow-up with a specialist physician. The importance of routine screening for pathologies that affect the breasts is highlighted, aiming at their early diagnosis. In addition, radiotherapy has good prognostic results at the expense of surgical treatment.

We report the disease characteristics, diagnosis, and treatment of granulomatous orchitis. A 38-year-old man presented with a history of intermittent swelling, pain, and discomfort in the right testicle of 3 days’ duration. Unenhanced magnetic resonance imaging (MRI) of the testis and scrotum revealed an oval mass in the right testis measuring approximately 17 mm in diameter, with clear borders and a target ring-like appearance from periphery to center. T1-weighted imaging (T1WI) showed uniform low-intensity signals, and T2WI showed mixed high- and low-intensity signals. Diffusion-weighted imaging (DWI) signals were iso-intense, and the outer ring on enhanced scans showed progressive enhancement. We performed radical resection of the right testis under combined spinal–epidural anesthesia. The pathological diagnosis was granulomatous right orchitis. Two months postoperatively, ultrasonography showed no testis and epididymal echo signals in the right scrotum, and no obvious abnormalities; color Doppler blood flow imaging (CDFI) findings were normal. Granulomatous orchitis is rare in clinical practice, and the cause is unknown. The disease involves non-specific inflammation; however, it is currently believed that antibiotics and steroids are ineffective for conservative treatment, and orchiectomy should be actively performed.

An 11-year-old female miniature Dachshund dog presented with a solid, soft, gray mass on the hepatic lateral left lobe. Histologically, the mass consisted of neoplastic proliferation of cells with round nuclei and eosinophilic and vacuolated cytoplasm arranged in alveolar, trabecular, and solid patterns. Immunohistochemically, the neoplastic cells were positive for pancytokeratin (CK AE1/AE3), CK5, CK14, vimentin, Sox9, and myoepithelial markers (α–smooth muscle actin, p63, and calponin). The morphological and immunohistochemical findings indicated a diagnosis of myoepithelial carcinoma. We conducted immunohistochemical studies on other representative canine hepatic tumors. Although the myoepithelial phenotype was not observed in the hepatocellular carcinoma, some tumor cells in cholangiocarcinoma showed immunohistochemical features of myoepithelium, suggesting that some neoplastic cells in cholangiocarcinoma may have the potential to differentiate into myoepithelial cells. To our knowledge, this is the first report in veterinary medicine of a hepatic carcinoma with a myoepithelial phenotype.

Background: Progressive mucinous histiocytosis (PMH) is a benign, non-Langerhans cell histiocytosis with characteristic ultrastructural features that can be used for diagnosis. Once an important tool in dermatologic diagnosis, electron microscopy has been largely replaced by immunohistochemistry and immunofluorescence techniques today. However, electron microscopy occasionally still plays a crucial role in the diagnosis of dermatologic conditions. We report a case of PMH as an example of a dermatologic disorder that requires electron microscopy for its diagnosis. Methods: A 60-year-old woman presented to our clinic with a history of small, sharply demarcated, skin-colored papules ranging from 2 to 5 mm in diameter distributed over the arms, forearms, and dorsal hands. The results of light microscopy, immunohistochemical studies, and clinical examination were inconclusive. Another biopsy for electron microscopy showed the characteristic features of PMH. Conclusion: This case demonstrates that a dermatopathology service still needs to have access to electron microscopy for diagnostic purposes to successfully diagnose a small number of rare conditions.

Metaplastic Breast Carcinoma

Introduction: Metaplastic breast carcinoma is an uncommon malignancy that constitutes < 5% of all breast cancers. There are 5 subtypes which are spindle cell, squamous cell, carcinosarcoma, matrix-producing and metaplastic with osteoclastic giant cells. Spindle cell carcinoma represents approximately <0.3% of invasive breast carcinomas. It is typically a triple-negative cancer with distinct pathological characteristics, but relatively a non-conclusive imaging findings. Case report: An elderly lady presented with an enlarging painful left breast lump for 1 year. Palpable left breast lump noted on clinical examination. Mammography demonstrated a high density, oval lesion with a partially indistinct margin. Corresponding ultrasound showed a large irregular heterogeneous lesion with solid-cystic areas. Histopathology showed atypical spindle-shaped cells which stained positive for cytokeratins and negative for hormone and human epidermal growth factor receptors, which favours spindle cell metaplastic carcinoma. Left mastectomy and axillary dissection were performed, and the final diagnosis was consistent with metaplastic spindle cell carcinoma. Conclusion: Spindle cell carcinoma of the breast is a rare aggressive histological type of carcinoma which may present with benign features on imaging. Tissue diagnosis is essential for prompt diagnosis with multidisciplinary team discussion to guide management and improve patient’s outcome.
