A 22^nd case report of extrauterine adenomyoma of the abdominal wall

Abstract

An adenomyoma of the uterus is a nodular tumor-like mass of benign endometrial glands, endometrioid stroma and smooth muscle tissue. Extra-uterine adenomyoma is an extremely rare tumor. The majority of the cases described was from ovary and located in the pelvis. We present a case of a 70 years old woman with clinical and radiological suspicious of disseminated malignancy. In the abdominal wall, a 5-cm nodule of larger dimension detected by computed tomography-scan was biopsied for accessibility reasons. The morphological and immunohistochemical features of the biopsy led us to propose the diagnosis of an extrauterine adenomyoma. This article reports the 22^nd case of extrauterine adenomyoma, a rare and poorly understood tumor that could be imagiologically and clinically indistinguishable from a metastasis.
