Abstract:
A 42-year-old woman presented with multiple, discrete, symmetric hyperkeratotic papules and comedo-like lesions over the cheek and upper part of the back. These lesions first began to appear at the age of 20 years. Since then, new lesions have periodically appeared with spontaneous regression. Keratinous material could be extruded, leaving behind pock-like scars. The scalp, palms, soles, and mucous membranes were spared. Because the lesions were asymptomatic, the patient did not seek any treatment (Figure 1 and 2). (SKINmed. 2022;20:152-153).

The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
