[Inflammatory pseudotumor the bladder wall after abdominal hysterectomy for uterine myoma]

We report on a 49-year-old woman who underwent an abdominal hysterectomy for uterine myoma. Six months after the primary surgery a 2 x 2 cm tumor was detected in the posterior wall of the urinary bladder. This tumor was associated with pain, dyspareunie and voiding disturbances. A repeat-laparotomy and partial resection of the urinary bladder were carried out. The histological and immunohistochemical examinations revealed an inflammatory pseudotumor of the urinary bladder. Similar lesions after surgery on the genito-urinary system were previously reported mainly in the urinary bladder. Difficulty may arise in differentiation of these lesions from low-grade leiomyosarcomas.
