Abstract
Perforating Granuloma annulare (GA) of palmar surfaces of both index fingers was observed in a 41 years female. Duration was 1½ years and papules were asymptomatic, yellow, firm, discrete, with central pits. FBS was 81 mg/dl. Histopathology revealed transepidermal elimination of altered collagen, foci of degenerated collagen surrounded by groups of mononuclears admixed with occassional eosinophil and giant cell in irregular palisade arrangement.
