Fibroma of the urinary bladder: a light and ultrastructural study of a case with review of

the literature in Japan. ∗

Tsuyoshi Murao, Masaki Kamoi, and Keno Asano

Abstract

A hard fibroma of the urinary bladder was found in an autopsy case of a 69 year-old female.

The tumor, 10x9x6 cm, occurred in the superior wall of the bladder. Ultrastructurally, the principal cells of the tumor were myofibroblasts. Fibroblasts and fibrocytes were also present. Including our case, the number of reported cases of pure fibroma of the urinary bladder in Japan is 12. These are reviewed briefly.
