Overview

Objective: Case description of dissecting uterine leiomyoma with extrauterine extension and infiltration of right parametrium, ureter and bladder wall.

Design: Case report.

Setting: Department of Pathology, Znojmo Hospital.

Methods: A 64-year-old woman with chronic pelvalgia and loss of renal function of the right kidney due to urinary tract obstruction is presented. Ultrasound examination, magnetic resonance imaging and computer tomography scan revealed a pelvic tumour affecting the right edge of the uterine wall, the right parametrium, distal part of the right ureter, the right and partially the cranial bladder wall. Due to this finding, hysterectomy, unilateral parametrectomy, partial resection of the bladder wall and resection of the distal part of the ureter was performed. Histology revealed morphologically bland spindle-cell smooth-muscle tumour corresponding to conventional uterine leiomyoma. Tumour necrosis, cellular atypia, vascular invasion or hydropic degeneration were not observed. A final diagnosis of dissecting leiomyoma of the uterus was made.

Conclusion: The diagnosis of dissecting leiomyoma should be considered in all malignant tumours affecting the uterine corpus.
