Abstract
We report a case of Hailey-Hailey disease characterized by a granular appearance. A 70-year-old man had erythema and erosion in the groin. He was diagnosed as Hailey-Hailey disease based on clinical and histopathological findings. About five years after the first examination, the numerous papules appeared bilaterally in the groins, leading to the granular appearance. Histological findings of the swelling portion of a papule revealed irregular epidermal thickening without acantholysis. Two-months’ treatment with maxacalcitol ointment cleared the skin lesion.
