[Ulcerative colitis and sclerosing cholangitis associated with elastosis perforans. A case review].

Transepidermal elimination is a mechanism by which altered dermal extracellular material is discharged through the epidermis. Perforating elastosis is a rare disease characterized by the transepidermal elimination of abnormal elastic fibers. Clinically it manifests as skin-colored keratotic papules that may coalesce and form arcuate or serpiginous plaques. It affects mostly males, predominantly younger than 30-years-old. We present a case of a male patient with inflammatory bowel disease and sclerosing cholangitis associated with perforating elastosis. To our knowledge, this is the first description of inflammatory bowel disease associated with perforating elastosis.
