Aspergillosis is an infection caused by saprophytic fungi of the genus Aspergillus, which typically occurs in immunosuppressed individuals, but has also been reported in immunocompetent patients. The main routes of entry are the respiratory tract, skin, cornea, and ear, and the infection may be localized or disseminated by contiguity or vascular invasion. We report a severe case of rhinosinusitis with cutaneous involvement, caused by invasive aspergillosis, in an immunocompetent user of inhaled cocaine. Invasive aspergillosis related to cocaine abuse has not yet been reported in the literature. After itraconazole treatment and surgical debridement, complete clinical remission was achieved. Nasal reconstruction with a skin graft over a silicone prosthesis resulted in a satisfactory esthetic outcome.

Colagenomas são hamartomas do tecido conjuntivo gerados por aumento anormal do colágeno dérmico. O colagenoma eruptivo caracteriza-se por pequenos nódulos duros, assintomáticos, sem relato de trauma ou processo inflamatório prévios. Descreve-se caso de paciente do sexo masculino, de 28 anos, que há 10 anos notou surgimento espontâneo de lesões papulosas no tronco, nos membros superiores e abdômen, e há três anos descobriu ser soropositivo para HIV. O diagnóstico diferencial, a classificação da doença como entidade própria e a associação casual com o HIV são discutidos, bem como a necessidade da realização da coloração vermelho Picrosirius/luz polarizada para confirmação diagnóstica dos colagenomas.

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.
