A 16-year-old girl was referred with a presumed muco-epidermoid carcinoma of the distal trachea, which was diagnosed by bronchoscopic biopsy. She underwent tracheal resection and end-to-end anastomosis. Final pathologic examination of the resected specimen revealed a benign oncocytic adenoma. This neoplasm is composed predominantly of oncocytes and is extremely rare in this location.

Oncocytoma: a rare neoplasm of the caruncle.
BMJ Case Rep

Ophthalmology, Madigan Army Medical Center, Tacoma, Washington, USA.
Oncocytoma is a rare benign neoplasm of the glandular tissue, most commonly found in the caruncle of the eye. These lesions have an excellent prognosis and have not been reported to recur after resection from the caruncle. Given the wide range of differentials and potential for malignancy, excision and histopathological examination are recommended to establish the diagnosis and guide proper treatment.

Renal cell carcinoma is an aggressive form of kidney cancer, contributing to an estimated 138,000 deaths globally in 2017. Traditional treatments like chemotherapy and radiation are generally considered ineffective. Additionally, CD47 has been identified as a crucial tumor antigen involved in the development and progression of various cancers, including renal cell carcinoma.

Oncocytic carcinoma is a rare malignant neoplasm of oncocytic cells, such cells being characterized by abundant granular eosinophilic cytoplasm, invasive growth, and pronounced cellular pleomorphism. It may arise de novo, or through malignant transformation of a pre-existing benign oncocytoma. Oncocytic carcinoma most commonly occurs in the salivary glands, with rare involvement of the ocular adnexa where it mainly affects caruncle, conjunctiva, and lacrimal sac, and only very arises in the lacrimal gland.

Introduction: In this study we aim to analyze the TRPS1 immunostaining of salivary gland tumors (SGT) on cytology cell blocks and compare the staining pattern on subsequent surgical resections.
Methods: Malignant SGTs, oncocytomas and basal cell adenomas diagnosed on fine needle aspiration were retrieved from 2019 to 2021 database. Cases with surgical follow-up were selected.

Objective: Renal oncocytoma is a benign renal tumour whose management remains heterogeneous and poorly codified. The aim of this study was to describe the management strategies and evolution of a cohort of biopsied renal oncocytomas.
Materials And Methods: We retrospectively reviewed renal oncocytomas biopsied in 2 French academic centres between 2009 and 2016.
