Metastatic hypopharyngeal carcinoma mimicking necrotizing vasculitis of the skin.

Clinical features of cutaneous necrotizing vasculitis were the presenting signs of a hypopharyngeal carcinoma in a forty-three-year-old man. A definite diagnosis was established by examination of fine-needle aspiration biopsy and scalpel biopsy specimens. Among the dermatoses simulated by metastatic pharyngeal carcinoma, necrotizing vasculitis has not, to our knowledge, been reported previously.
