Abstract
-
Transepidermal elimination is a mechanism whereby foreign or altered constituents can be
removed from the dermis. The phenomenon of transepidermal elimination may occur as a primary
process characterizing disorders such as elastosis perforans serpiginosa, reactive perforating
collagenosis and chondrodermatitis nodularis chronica helicis; as well as a secondary process
characterizing disorders such as granuloma annulare, necrobiosis lipoidica diabeticorum,
calcinosis cutis, pseudoxanthoma elasticum, spitz nevi, pimented nevi, porokeratosis plantaris
discreta and metastatic tumors. A 17-year-old man presented with a 2X2 cm sized
well-circumscribed slightly erythematous plaque with some black colored papules on the left
dorsum of his hand. The histopathology of the lesion indicated angiokeratoma circumscriptum
with transepidermal elimination.
