Abstract

A middle-aged man develops sudden progressive hyperpigmentation of his axillae and groins associated with a rugose surface. What is the diagnosis?

Key Points

A 54-year-old man suddenly developed progressive hyperpigmentation of his axillae (Figure 1) and groins associated with a rugose surface. Skin biopsy showed a papillomatosis epidermis with a mildly pigmented basal layer and a loose, laminated stratum corneum (Figure 2).
