Ovarian leiomyoma ? case reports and literature review

Introduction. Ovarian leiomyoma is a rare benign ovarian tumor accounting for 0.5–1.0% of all benign ovarian tumors. The paper presents four cases of ovarian leiomyoma detected post-operatively by histopathological examination in patients treated at the Gynecology and Obstetrics Ward of the Specialist Hospital in Radom, Poland, in the period of 1998– 2017. Material and methods. A retrospective analysis involved surgical and histopathological reports. A 51-year-old patient underwent hysterectomy with bilateral removal of the adnexa. Three patients had the uterine body amputated: in a 49- year-old patient, the adnexa were preserved and a myoma of the right ovary was excised; in a 59-year-old patient, the adnexa were removed bilaterally and a myoma of the rectouterine pouch was excised; in a 54-year-old patient, the adnexa were removed bilaterally. Final diagnoses were made on the basis of post-operative microscopic examination of the specimens. Moreover, the article reviews accessible literature on ovarian leiomyoma. Results. Leiomyomas were located on the right side in all cases. Concomitant occurrence of endometriosis and ovarian leiomyoma was detected in two cases, and in one of them uterine myomas were accompanied by a myoma in the rectouterine pouch. Conclusions. A diagnosis of ovarian leiomyoma is made on the basis of a histopathological examination. Surgical treatment depends on patient’s age, her intention to remain fertile, the extent of the lesion and concomitant problems affecting her genital organs.
