Based on clinical manifestations, porokeratosis can be classified as porokeratosis of mibelli, disseminated superficial porokeratosis, disseminated superficial actinic porokeratosis, linear porokeratosis (LP), porokeratosis palmaris et plantaris disseminata, porokeratosis punctata, popular PK, hyperkeratosis PK, inflammatory PK, verrucous PK, and mixed types. We report a case of LP in a child and describe its dermoscopic findings.
CASE SUMMARY
Linear porokeratosis is a rare PK. The patient presented with unilateral keratinizing maculopapular rash of the foot in childhood. The patient underwent skin pathology and dermoscopy, and was treated with liquid nitrogen freezing and topical drugs.
CONCLUSION
From this case we take-away that LP is a rare disease, by the dermoscopic we can identify it.
Core Tip: We report a case of unilateral linear porokeratosis. Porokeratosis is a common autosomal dominant chronic progressive dyskeratosis with a variety ofvarious clinical manifestations. Dermatoscopy plays an important role in the differential diagnosis of a various diseases and has been widely used in clinical practice because it is noninvasive, simple, and quick.
