Carcinoid of the Ovary: Diagnostic Challenge on Fine-Needle Aspiration Cytology

Carcinoid of the ovary is an uncommon tumor. In the present article we have described the cytological features of carcinoid of the ovary in a 53-year old post-menopausal female. The patient presented with abdominal discomfort and loose stools. Ultrasound-guided fine-needle aspiration cytology (FNAC) of the left adnexal mass showed clusters and also scattered, relatively monomorphic population of tumor cells with vague rosette-like structures. Cytological diagnosis of malignant ovarian tumor possibly sex cord stromal tumor or carcinoid of ovary was offered and subsequent histopathology and immunohistochemistry confirmed the diagnosis of carcinoid.
