Abstract
We present three cases of a rare eruptive variant of tumor of follicular infundibulum.
Two patients presented with hypopigmented macules. The clinical differential diagnoses
considered in these two cases were vitiligo, lichen sclerosus et atrophicus, and idiopathic
guttate hypomelanosis. In the third case, the lesions were hypopigmented fl at topped
maculo-papules diagnosed clinically as verruca plana. In all three cases, the histopathological
features of plate like growth of pale keratinocytes connected to the epidermis and peritumoral
condensation of elastic fi bers were diagnostic. Although no satisfactory treatment is available,
the exclusion of other clinical differential diagnosis particularly vitiligo with its psychosocial
implications underscores the importance of skin biopsy.
