Abstract

Spiny keratoderma is a rare entity characterized by the presence of multiple millimetric hyperkeratotic lesions, with a filiform appearance, distributed on the palms and soles. Although hereditary cases with autosomal dominant pattern have been described, most of them are acquired and have been associated with different metabolic, infectious and neoplastic conditions. We present the clinical case of a 38-year-old female patient who consulted with a ten-month-old dermatosis on her palms of ten months of evolution, clinically and histologically compatible with spiny keratoderma.
