A diagnostic dilemma: A rare case of an ovarian carcinoma with signet ring cells hidden behind a substantial dermatomyositis

: Dermatomyositis (DM) is a malignancy-associated inflammatory connective tissue disease which involves muscles and skin. It accompanies many cancer types. Herein, we aimed to present a 42-year-old patient with primary signet ring cell ovarian carcinoma which has not been seen hitherto. Presentation with DM induces rapid and aggressive progression and emphasizes the importance of more comprehensive malignancy screening in these patients.
