Mammary analogue secretory carcinoma (MASC) is a salivary gland tumour with low-grade potential and specific FTV6 derangement having translocation of chromosomes t (12;15) (p13;q25). It shares a similar morphological as well as an immunohistochemical profile with secretory carcinoma (SC) of the breast making it a diagnostic enigma.
In this report, we discuss the case of a 65-year-old male patient, who presented with a complaint of right-sided facial swelling. To rule out the differential, he underwent various diagnostic modalities, including magnetic resonance imaging, fine-needle aspiration and it’s the tumour’s microscopic and immunohistochemical properties were also reviewed. Parotidectomy along with concurrent chemo-radiotherapy was performed to eradicate the growing mass.

A giant cell tumor of the bone is among the most common bone tumors encountered by orthopedic surgeons. These benign and aggressive tumors are most commonly present around the knee joint; however, rare cases may involve the distal fibula. An 18-year-old man presented with a painless swelling of the lateral aspect of the left ankle. Clinical examination, radiologic evaluation, and biopsy confirmed the diagnosis of a giant cell tumor of the distal fibula. The patient was treated with resection of the distal fibula followed by reconstruction using an ipsilateral proximal fibula graft. The post-operative recovery was uneventful, and the patient was doing well on the last visit, one month after the intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
