[Keratosis lichenoides chronica following trauma. A case report and update of the last literature review].

Since the original description by M. Kaposi in 1895, 40 cases of keratosis lichenoides chronica have been published. Most have been reports of single cases. The clinical appearance is characterized by lichen planus-like papules, linear keratoses, and psoriasis-like plaques. While the etiology is still unknown, an association with a variety of diseases including hepatitis, tuberculosis, glomerulonephritis, and lymphoproliferative diseases has been reported. We present a new case which may have been triggered by trauma or carbamazepine.
