Annular elastolytic giant cell granuloma occurring in covered areas.
A 72-year-old male had 7 erythematous infiltrated areas of 3-7 cm in diameter on the sun-unexposed areas, i.e., the chest, abdomen and inguinal region. While the centers of the lesions were flat and slightly reddish or normal skin-colored, the margins were flesh-colored and elevated, and the lesions were generally annular or of letter C form. An old lesion on the nucha was depigmented, slightly depressed and soft on palpation. Histological sections revealed giant cell granuloma with loss of elastic fibers.
