Case report: Giantadenomatoidtumour of uterus mimicking like large leiomyoma

Abstract

INTRODUCTION: Adenomatoidtumours of uterus are rare benign neoplastic disorder of the female genital tract. Even though reported incidence is around 1-2% true incidence is probably more than that as they are not usually symptomatic. Most cases are under 3 cm in diameter, but giant variants up to 15 cm in diameter are also described. Here, we describe a case of giant adenomatoid tumor of the uterus that was managed surgically. CASE HISTORY: A 24-year-old nulliparous woman presented with abdominal distension, regurgitation and early satiety of five months duration. She did not have any menstrual disorders. Abdominal examination revealed a large pelvic tumourcorresponding to 20 weeks gravid uterus. Ultrasonography revealed a large uterus with multiple fibroid. She underwent a laparotomy,a subserosal mass arising from the posterior uterine wall near the fundus and extending to the left uterine cornuwas found. It was not a welldefined mass and consistency was firm in nature. Tumour was easily enucleated and sent for histology. Uterus was repaired into two layers.Post-operative recovery was uneventful.The histology report revealed as adenomatoid tumor of the uterus. DISCUSSION: Adenomatoidtumour arises from the germinal epithelium of abdomen and thorax. It is a variant of mesothelioma. They can beassociated with fibroids and tend to mimic them clinically, making pre-operative diagnosis difficult. Macroscopically, most appear as nodular formations with ill- defined margins and can occur in ovary, mesentery, adrenal glands, and omentum. Rarely do they recur even after conservative surgery and so far no malignant transformation has been reported. Therefore, the recommended treatment is simple excision of the tumor, if possible.
