RESUMO
Mucormycosis is a life-threatening fungal infection mostly involving the ocular region, sinuses and brain. It is mostly seen in the immunocompromised host. Gastrointestinal (GI) mucormycosis is rare and mostly present as hematemesis, abdominal pain and melena. Here, we present a case of intestinal mucormycosis who presented as cecal perforation. Surgical resection was done, and the diagnosis was made by histopathology. Our case is unique in the way that GI mucormycosis is itself a rare entity and even rarer in an immunocompetent host.

Pulmonary ossification is also known as metaplastic bone formation. It is a rare and incidental post-mortem finding. Dendriform and nodular pulmonary ossification are the two forms which are recognized, and they are usually associated with systemic or primary lung pathology. Its awareness is necessary to correctly diagnose and differentiate them from other lung pathologies. Histopathology aids in the accurate diagnosis of this dormant entity. Herein, we present an autopsy case of a 37-year-old male with pulmonary ossification discovered incidentally during an autopsy.
RESUMO
Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland carcinoma that resembles the secretory carcinoma of the breast and is characterised by t(12;15) (q13;q25) translocation, which results in an ETV6-NTRK3 gene fusion product. On cytomorphology, it is characterised by papillary fragments, clusters, and singly dispersed tumour cells. These tumour cells are large and have abundant vacuolated cytoplasm. Acinic cell carcinoma of the salivary gland is the most common differential diagnosis of MASC. Other differentials include mucoepidermoid carcinoma, salivary duct carcinoma, pleomorphic adenoma, and oncocytic salivary gland neoplasms. Immunohistochemistry and morphology are critical in establishing the correct diagnosis. We present a case of a 46-year-old male patient diagnosed as MASC of the parotid gland on fine needle aspiration cytology and cell block.
