Multiple Eruptive Dermatofibromas in a Patient with HIV infection
Miroux Catarino, Alexandre; Soares-de-Almeida, Luís; Borges-Costa, JoãoMultiple eruptive dermatofibromas is a rare event characterized by the appearance multiple dermatofibromas in few months. It is usually associated with immunodysregulation/immunosuppression. An appropriate work-up of underlying diseases must be done after this diagnosis, including search for HIV infection and lupus erythematosus.

Vitamin D deficit has been associated with an increased risk for various diseases, including autoimmune, neoplastic, cardiovascular and neurological disorders. However, areas of controversy remain: a direct cause-effec...
