Two patients with histopathological diagnosis of cutaneous vasculitis of atypical clinical course are presented. The first patient was a 13-year-old boy with bullous lesions and generalized phlyctenules measuring 2-3 cm with no superinfection, which began in the oral cavity and extended to the anterior chest and extremities, associated with ventilation-respiratory community acquired pneumonia (CAP), which required antibiotic therapy and systemic corticoids, with complete resolution at 17 days and definitive diagnosis of hypersensitivity vasculitis. The other patient corresponds to a 58-year-old man with purpuric macular lesions in upper and lower extremities of 18 months duration. Some of them were confluent purpuric plaques not greater than 5 cm. Patient had associated diabetes, retinopathy and hypertension. Biopsy showed leukocytoclastic vasculitis with the presence of “promontory sign” suggestive of Kaposi´s sarcoma which was ruled out. The definitive diagnosis was lymphocytic vasculitis in a patient with pytriasis lichenoids chronica (PLC).
