PHEOCHROMOCYTOMA REVEALED BY DIGITAL NECR OSIS

Background. Cutaneous manifestations of pheochromocytoma other than sw earing, and facial pallor during paroxysmal episodes of hypertension a re exceptional. Case report. We observed partial necrosis of the fourt h toes which revealed pheochromocytoma. Discussions Signs of periphera l vascular disease are uncommon during the course of pheochromocytoma. Only four cases have been reported in the literature. Occurrence of d istal necrosis in combination with hypertension and palpable pulses is suggestive of pheochromocytoma requiring assay of urinary catecholami nes. The pathogenic mechanisms of necrosis would be vasospasm of cutan eous vessels due to excessive plasmatic catecholamine levels and throm bocytosis as an aggravating factor.
