COIMBRA, Daniel Dal'Asta et al. Eruptive collagenoma in an HIV-positive patient. An. Bras. Dermatol. [online]. 2008, vol.83, n.2, pp.141-145. ISSN 0365-0596.

Collagenomas are connective tissue nevi predominantly composed of excessive dense and coarse collagen in the dermis. Eruptive collagenoma is a rare disorder occurring in young adults as asymptomatic dermal nodules, with no previous history of injury or inflammation and usually localized on the back. We describe the case of a 28-year-old male patient who was examined for numerous asymptomatic little nodules on the trunk and upper arms, which appeared ten years ago with no previous inflammation or injury. Three years ago the patient was diagnosed HIV-positive. Differential diagnoses, classification of the disease as an autonomous entity, its casual association with HIV, as well as the real need for picrosirius red staining to confirm diagnosis of collagenoma are discussed.
