Cutaneous calciphylaxis of the glans penis presenting as a gangrenous ulceration

摘要

Cutaneous metastasis are uncommon and account for only 2% of all skin cancers, but are extremely rare in hypopharyngeal carcinomas. Although often associated with advanced cancer, cutaneous metastasis can be the first indication of relapse or treatment failure. Additionally, the clinical presentation is widely variable, which can make an early diagnosis difficult. New skin lesions should be evaluated in cancer patients to rule out metastases. Herein, we present a patient with an unusual cutaneous metastasis as the first sign of recurrence of a hypopharyngeal carcinoma.
