Fibrosarcoma of the corpus cavernosum: case report and literature review
1Department of Urology, Zhuzhou Hospital Affiliated to Xiangya School of Medicine, Central South University, ZhuZhou, China.
Background:
Fibrosarcoma is a very rare tumor that arises from fibrous tissue. Less than 5% of fibrosarcoma originate from the urogenital tract. Penile fibrosarcoma, even more rare, is characterized by pain, enlargement, penile erection and urinary tract obstruction. To our knowledge, this is the second reported case named "fibrosarcoma of the corpus cavernosum".
Case Presentation:
A 51-year-old male presented with a 1-month history of penis pain during erection. CT scan showed a soft tissue mass arising from the proximal part of the penis. We diagnosed it as penile sarcoma, performing local excision. The postoperative pathological result was moderately differentiated fibrosarcoma. 3 months later, CT scan showed the recurrence of the tumor, and multiple metastases. Although he received chemotherapy, he died 10 months after surgery.
Conclusions:
Fibrosarcoma of the corpus cavernosum is rare and have poor prognosis. Total penile amputation may be the best treatment. The effects of chemotherapy are limited. No more effective treatment has been found for a disseminated disease to date.
