ANNULAR ELASTOLYTIC GIANT-CELL GRANULOMA

A 49-year-old woman had large annular lesions with raised erythematous borders and atrophic, hypopigmented central regions on her neck, trun k, and proximal upper extremities. Examination of a biopsy specimen de monstrated a granulomatous infiltrate in the upper dermis that surroun ded areas lacking elastic fibers; elastic fibers were present within t he multinucleated giant cells. The clinical presentation and pathologi c findings were consistent with a diagnosis of annular elastolytic gia nt cell granuloma (AEGCG). The clinical description and pathologic dif ferential diagnosis of AEGCG are reviewed.
