Purpura annularis telangiectodes of Majocchi.
A case is presented of a man with a 3-year history of ulcers in the setting of pigmented, annular and purpuric lesions of the lower extremities. A skin biopsy suggested a diagnosis of purpura annularis telangiectodes of Majocchi. First described in 1896 by Majocchi [1], purpura annularis telangiectodes is an uncommon pigmented purpuric eruption, which is characterized by symmetrical, purpuric, telangiectatic, and atrophic patches with a predilection for the lower extremities and buttocks. Histopathology and immunopathogenesis of this disease are similar to the other subtypes of pigmented purpuric dermatoses.
