Palmar and Plantar Pits, More than Just Viral Warts.

A 40-year-old woman with a family history of gastric, pulmonary, and endometrial cancers (parents and grandparents) was referred to our institution with a 3-year history of progressive pruritus with palmar and plantar papules. On physical examination, there were keratotic yellowish pinpoint papules on the hands (Figure 1) and yellowish keratotic plaques and papules on the plantar pressure points (Figure 2). The diagnosis of punctate palmoplantar keratoderma was confirmed histopathologically (Figure 3), and treatment was initiated with 30% urea cream, which proved helpful.

Water-induced dermatosis: Aquagenic keratoderma. A case report.

Aquagenic keratoderma is a benign entity that is characterized by producing whitish or translucent papules a few seconds after contact with water. We present the case of a 16-year-old patient with multiple asymptomatic confluent papules that appeared on both hand palms after contact with water and which disappeared after drying. The histopathological findings in a skin biopsy after water exposure showed changes in the superficial layers of the stratum corneum and dilatation of sweat gland ducts.
