Erythrokeratodermia variabilis et progressiva 2

Erythrokeratodermia variabilis et progressiva-2 (EKVP2) is a genodermatosis characterized by persistent plaque-like or generalized hyperkeratosis and transient red patches of variable size, shape, and location. The severity and dominating features of the disease vary strikingly within families and also during an individual's course of disease. The erythematous component usually prevails in young children, whereas hyperkeratosis is the dominant or sole feature in adults. Some patients with EKVP2 display lesions resembling erythema gyratum repens (summary by Richard et al., 2003). EKVP was previously thought to be separate disorders: erythrokeratodermia variabilis (EKV) and progressive symmetric erythrokeratodermia (PSEK) (van Steensel et al., 2009). For a discussion of genetic heterogeneity of EKVP, see EKVP1 (133200). [from OMIM]
