From: Surgical treatment of primary cardiac valve tumor: early and late results in eight patients
(Case 4, Mitral valve rhabdomyoma) a: A light-red elliptical neoplasm with smooth surface, shaved completely from the mitral anterior leaflet, 1 × 0.8 × 0.4 cm3. b: Histologically, the tumor was highly cellular and composed of somewhat pleomorphic, polygonal muscle cells admixed with spindle-shaped cells. There was “spider web” appearance in some tumor cells which has been known as the classic microscopic finding for rhabdomyoma. The tumor showed widely myxoid degeneration. (Hematoxylin and eosin)
