Dr. Naqsh Thakur, Dr. Yogita Bhansali* and Dr. Aabha Sharma

ABSTRACT

Signet ring cell stromal tumor of the ovary is an exceptionally rare subtype of sex cord-stromal tumors characterized by signet ring-like morphology without mucin production. These tumors can pose diagnostic challenges due to their unusual histological appearance, which may mimic metastatic signet ring cell carcinomas, particularly from the gastrointestinal tract. We present a case of a 52-year-old postmenopausal woman with an incidental finding of an ovarian mass discovered during evaluation for nonspecific abdominal discomfort. Histopathological and immunohistochemical analysis confirmed the diagnosis of a signet ring cell stromal tumor. This case underscores the importance of accurate morphological evaluation and immunoprofiling in the diagnosis of this rare entity to avoid misclassification and inappropriate management. A comprehensive review of the literature is also included to contextualize this rare diagnosis.
