Leiomyomatosis in the pelvic lymph node and peritoneum

摘要

This paper is concerned with a rare clinical entity, i.e. leiomyomatosis of pelvic promontory lymph node in a 50−year‐old Japanese woman and leiomyomatosis peritonealis disseminata in a 41−year‐old one. Despite such daughter nodules, all of the leiomyomas showed benign histological features. Morphogenesis of the discontinuous leiomyomas was discussed in relation to pelvic endometriosis. Because of a favorable prognosis in the leiomyomatosis, no more aggressive therapy than that necessary to extirpate the tumor is recommended. Acta pathol. jpn. 34: 813∼
