Em pacientes com hipertricose lanuginosa adquirida crescem pelos do tipo lanugo (ou seja, fetais) perto das sobrancelhas e em fronte, orelhas e nariz. Alguns pacientes têm envolvimento extenso que inclui as extremidades, as axilas e o tronco, mas as palmas, as plantas e o períneo são poupados. O pelo, referido como penugem maligna, é delgado, fino e não pigmentado, diferente dos pelos terminais pigmentados robustos característicos do hirsutismo. Embora a hipertricose adquirida possa ser provocada por outras doenças ou drogas, a presença de hipertricose lanuginosa adquirida inexplicável deve levar a uma extensa pesquisa por malignidade oculta. | |||

The hair, referred to as malignant down, is fine, thin, and unpigmented, unlike the robust pigmented terminal hairs characteristic of hirsutism.
