Atypical Cutaneous Mucinosis Treated with Intravenous Immunoglobulin and Corticosteroid.

ABSTRACT

FA 25-year-old man presented with a 12-month history of progressive skin lesions involving the face, upper areas of the trunk, arms, and natal cleft. There was moderate pruritus, disfiguring lesions of the face, and mild arthralgia. No therapy had been applied before the referral to our clinic. On physical examination, there were skin-colored nodules on the face (Figure 1A), along with multiple firm subcutaneous nodules and tumors with a fairly symmetrical distribution on the extensor surface of the hands and forearms (Figure 2A). Dense papular lesions were found on the upper part of the back (Figure 3A). There was also a waxy infiltrated plaque in the natal cleft area (Figure 4A).
