title: Granuloma annulare: radiographic demonstration of progressive mutilating arthropathy with vanishing bones.
abstract: Granuloma annulare, a relatively common cutaneous disorder of unknown origin, is named for its predominantly papular lesions, which tend to group and coalesce in an annular fashion. Clinically distinct subtypes are divided into localized, generalized, perforating, and subcutaneous forms. Only the superficial granulomata of the extremities in subcutaneous granuloma annulare have been radiographically depicted in the literature. We describe and illustrate what we believe is the first radiographic presentation of bone and joint involvement with advanced, generalized granuloma annulare.
