Clinicopathological correlation in 50 cases of erythroderma.

Fifty cases of erythroderma were studied clinically and histopathologically. Clinically 11 were of eczemas, 12 of psoriasis, 14 were drug-induced, 11 of idiopathic group and 1 each of pemphigus foliaceus (PF) and cogenital bullous ichthyosiform erythroderma (CBIE). Histopathologically 10 cases of psoriasis, 1 of PF and 1 of CBIE showed specific histopathology and therefore clinical histopathological correlation was possible only in 12 (24%) cases. Exact differentiation in erythroderma due to eczemas, drugs or idiopathic was not possible histopathologically.
