Parauterine leiomyomas in women: a clinicopathologic study of 22 cases.

During a systematic pathologic study of surgically excised parauterine connective tissues 22 parauterine leiomyomas were found, of which 10 were paracornual, 6 parametrial and 6 perisalpingeal. Their prevalence was 2.4% (22/928) among patients requiring hysterectomy for common gynecologic conditions. There tumors were often concurrent with intrauterine leiomyomas. Their etiology and clinical relevance are discussed.
