AIMS One of the limitations of fine needle aspiration biopsy (FNAB) of the breast is in distinguishing invasive carcinoma (IDC) from ductal carcinoma in situ (DCIS). It has been proposed that the presence of myoepithelial cells overlying epithelial malignant cell clusters suggests DCIS. However, the recognition of myoepithelial cells in aspirates may be difficult. The aim of this study was to i...

Hybrid carcinoma of the salivary gland is a very rare entity that has been described only in the parotid and palate. The occurrence of a hybrid carcinoma of maxillary sinus has not been reported. The diagnosis of hybrid carcinoma is important particularly when the components of tumor have different biologic behaviors. Diagnosis and treatment require a high index of suspicion, especially when th...

To describe our experience with a case of epithelial myoepithelial carcinoma that was reported as two different entities and thus proved to be challenging case. : Retrospective review histo-pathological reports detailed work up final findings treatment. Four year follow the patient shows successful treatment no recurrence. High index suspicion evaluation IHC testing is needed in tumours present...

Background and Aim: Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the salivary glands with complex histopathologic features and clinical behavior. The aim of this study was to evaluate the clinicopathologic significance of p63, Maspin and matrix metalloproteinase (MMP)-2 expression in MEC. Materials and Methods: In this retrospective study, immunohistochemical stain...

We present what is believed to be the first report of heterogeneous carcinoma arising from breast ductal adenoma. A 57-year-old woman presented with a nodule in her right breast. Histological examination of a vacuum-assisted biopsy specimen revealed epithelial tubular proliferation and papillary apocrine epithelium. The myoepithelial cells lining the tubules were confirmed by immunohistochemist...

This paper reports a case of low-grade adenosquamous carcinoma (LGASC) arising in a 69-year-old woman, who presented with a 1-cm palpable mass on her right breast. Core needle biopsy diagnosed the mass as a fibroadenoma. After six months, the mass increased in size, and the patient received subsequent mammotome excision. On microscopic examination, bland-looking small glands were infiltrating i...

Here we present a series of infiltrative ductal carcinoma breast cases (infiltrative ductal carcinoma with central necrosis) so closely mimicking 'DCIS with central comedo necrosis' that on initial morphological analysis these foci of tumors were labeled as DCIS (high grade, comedo). However on further histological work up and by using immunohistochemistry (IHC) for myoepithelial markers it was...

Breast glands and salivary glands are tubulo-acinar exocrine glands that can manifest as tumours with similar morphological features, but that differ in incidence and clinical behaviour depending on whether they are primary in breast or salivary glands. Salivary gland-like tumours of the breast are of two types: tumours with myoepithelial differentiation and those devoid of myoepithelial differ...
