A unique case was recently encountered involving the synchronous presentation of five primary malignancies of different histology. Malignant neoplasms of the colon, kidney, prostate and bladder were treated surgically. Bladder was affected by two separate tumours: a transitional cell carcinoma and a malignant fibrous histiocytoma. The latter constitutes an extremely rare malignant lesion of the organ. The pathologic characteristics, histogenesis, differential diagnosis and treatment considerations of this soft tissue sarcoma, and the incidence, terminology and incriminating factors of multiple primary malignant neoplasms, as well as their association with the genitourinary system are reviewed.
