Large ovarian leiomyoma in young woman
A 22-year-old woman was referred to our hospital for abdominal pain and palpable mass at lower abdominal region. Biochemistry laboratory results were not contributory. On computed tomography scan a large mass was revealed close to uterine. The patient was undergone surgical treatment and the large well circumscribed ovarian mass was excited. The left ovary was occupied by this mass without any attachment to other organs.\nOn gross examination, the mass was grayish white and measured about 14.5 × 11.5 × 10 cm. the mass had whorling pattern in cut surface. There was no any hemorrhage or necrosis [].\nOn microscopic examination, the tumor show interlacing bundles of spindle cells with some area of hyalinization. There were no mitosis, necrosis, and atypia [].\nFor confirming the initial diagnosis of ovarian leiomyoma and rule out other ovarian sex cord-stromal tumor, immunohistochemical staining for actin, desmin, and inhibin was performed. The cells showed positive staining for actin and desmin but not for inhibin, so the diagnosis of ovarian leiomyoma was confirmed.
