Calcifying uterine leiomyoma invading the urinary bladder

Leiomyomas are common benign tumors of the female genital tract and can be the leading cause of dysfunctional uterine bleeding, recurrent miscarriage or abdominal discomfort. Degeneration of fibroids occurs in menopause and is associated with fatty, hyaline, cystic, or myxoid degeneration or dystrophic calcification. However, based on their benign nature, these tumors are not known to invade other tissues. We here describe a rare case of an extensively calcified myoma invading the urinary bladder in an elderly patient who presented with hematuria and moderate abdominal discomfort.
