Diagnostic features of metastatic endometrioid carcinoma in a captive black-tufted marmoset (Callithrix penicillata)

J Med Primatol. 2024 Aug;53(4):e12727. doi: 10.1111/jmp.12727.

Abstract

A captive marmoset developed metastatic endometrioid carcinoma (EnC), a rare uterine tumor in non-human primates (NHPs). The neoplasm showed marked microscopical malignant and tubulopapillary aspects, immunopositivity for pan-cytokeratin, CK7, estrogen receptor, and a high mitotic index (Ki-67). These features may contribute to the diagnosis and therapeutics of EnC in NHPs.

Keywords: Callithrix; estrogen receptor; immunohistochemistry; neoplasm; non‐human primates; reproductive system; uterine tumor.
