A 48-year-old man presented with a 10-year history of asymptomatic, hypopigmented lesions on the face which were initially small and gradually increased in number and size. Physical examination revealed approximately twenty, similarly sized, round to angulated, hypopigmented macules on the beard area and neck [Figure - 1]a and [Figure - 1]b. The clinical differential diagnoses included pityriasis versicolor, pityriasis alba, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and epidermodysplasia verruciformis. Skin biopsy from one of the lesions revealed dilated follicular infundibula connected to each other and the overlying epidermis by a broad plate-like proliferation of cells that resembled isthmic epithelium with pale pink cytoplasm [Figure - 2] and [Figure - 3].
