血腫を伴った精巣白膜コレステリン肉芽腫の1例

Abstract

A case of cholesterol granuloma with hematoma of the tunica albuginea is reported. A 52-year-old man complained of a painless mass in the left scrotum. The mass was 50 x 25 x 30 mm in size. An operation was performed. Macroscopically the mass originated from the tunica albuginea and was a cystic lesion with a thick fibrous capsule. The cystic lesion was filled with an old hematoma. An extirpation was performed. Microscopically, the sections showed fibrogranulomatous tissue containing innumerable cholesterol clefts and numerous foreign body giant cells. The histological diagnosis was cholesterol granuloma with hematoma. This is the sixth case of cholesterol granuloma of the external genitalia, and is the first case of cholesterol granuloma with hematoma of the tunica albuginea in the literature.
