Acroceratose neoplásica é uma dermatose psoriasiforme acral rara associada a malignidade interna, mais frequentemente carcinoma de células escamosas do trato aerodigestivo superior. Comumente se apresenta antes que a malignidade se torne aparente. Caracteriza-se por placas simétricas, escamosas e violáceas que acometem a pele das mãos e dos pés, com proeminente distrofia ungueal associada. Em casos graves, bolhas podem se formar e as unhas podem cair. Alterações na pele podem se espalhar para as hélices dos pavilhões auriculares, ponta nasal e o couro cabeludo, onde a alopecia pode se desenvolver. | |||
