[Discolouration of Upper Lid Skin - Prurigo nodularis]. / Hautverfärbung am Oberlid ­ Prurigo nodularis.

ABSTRACT

An abnormal change in skin colour is designated as discolouration of the skin. A 73-year-old male patient with circumscribed discolouration of the upper lid margin near the lacrimal pathway is presented. Slit lamp biomicroscopy showed no other signs of pathomorphological change. An excisional biopsy was performed. The whole abnormal area was removed. The oculoplastic procedure was the surest way to establish a definite diagnosis of Prurigo nodularis.
