Abstract

Objective: To report a case with cutaneous metastasis of bladder squamous cell carcinoma. Very few cases of skin metastases from the urinary bladder are reported in the literature.
Case report: Cutaneous metastasis of bladder squamous cell carcinoma is an extremely rare clinic entity associated with poor prognosis. Cutaneous metastasis is accepted as a late manifestation of systemic spread. A 58-year-old man had undergone radical cystoprostatectomy with pelvic lymph node dissection in November 2013. The pathology report showed a moderately differentiated squamous cell bladder carcinoma with a staging of T3N0M0. Then, a large regional cutaneous lesion measuring 4x3.5 cm with an ulcerated and necrotic appearance located in the suprapubic area was detected in February 2014, and the lesion was removed with a 2 cm safety margin. The pathologic examination revealed squamous cell carcinoma. This report describes an interesting and rare case of cutaneous metastasis of bladder squamous cell carcinoma as the primary presentation of metastatic disease with a generally dismal prognosis.
Conclusion: The skin metastasis of bladder squamous cell carcinoma is a rare clinical entity with a poor prognosis. Clinicians should be aware of this rare entity.

Key words: bladder cancer, squamous cell carcinoma, metastasis
