Sir, erythrokeratoderma is a heterogeneous group of inherited cornification disorders which presents with erythematous hyperkeratotic plaques which are either migratory or stationary. Progressive symmetric erythrokeratoderma (PSEK) is a rare subtype characterized by nonmigratory, hyperpigmented, symmetric plaques that are usually distributed on the extremities, buttocks and sometimes the face. Very few cases of PSEK are reported from India.
