Keratolysis exfoliativa (also known as "lamellar dyshidrosis", "recurrent focal palmar peeling", "recurrent palmar peeling"  ) is a sometimes harmless, sometimes painful skin condition that can affect the focal surface of the fingers and/or the palm or soles of the feet. It is often misdiagnosed as chronic contact dermatitis or psoriasis. It is characterized by dry skin and superficial, air-filled blisters. These blisters can be peeled off very easily and will leave reddish, tender areas. The loss of this horny layer of the skin, which protects the underlying layers, leaves the skin more vulnerable to dryness and cracking.
Ceratopyxis is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, viz. Ceratopyxis verbenaceae, which is endemic to Cuba. It is a resinous small tree or bush with 4.5-8 centimeter oblong leaves. The fruit it produces is 4-5 millimeters in diameter, and with small hairs attached to the skin.
Pitted keratolysis (also known as Keratolysis plantare sulcatum, Keratoma plantare sulcatum, and Ringed keratolysis ) is a bacterial skin infection of the foot. The infection is characterized by craterlike pits on the sole of the feet and toes, particularly weight bearing areas.
