ABSTRACT
Erythoderma first described by Hebra in 1868 is a reaction pattern, characterised by generalised and confluent erythema with desquamation affecting more than 90% of body surface and is usually accompanied by systemic manifestation including some metabolic changes. Tile study was envisaged to assess their profile of aetiology, clinical features and to correlate with histopathological findings. Twenty-four patients (18 males and 6 females) with erythroderma were considered for the study. All patients were hospitalised, detailed history was taken and were subjected to relevant investigations--haemogram, serum proteins, liver and renal function tests, routine and microscopic urine tests, HIV screening, x-ray chest, ultrasound abdomen, FNAC of enlarged lymph nodes and skin biopsy. The age group affected ranged between 7 and 70 years, peak incidence between 50 and 60 years. The male to female ratio was 3:1. Scaling, erythema and pruritus were predominant clinical manifestations. In 12 clinically suspected psoriatic erythroderma, only in 6 cases the histopathological features were correlated to psoriasis and remaining showed non-specific chronic dermatitis. Two patients were found to be HIV-positive. There is good clinicopathological correlation in erythroderma caused by lichen planus, atopic dermatitis, seborroeic dermatitis, non-bullous congenital ichthyosiform erythroderma. Drugs were found to be aetiological factor in 3 cases. The study was conducted to assess variations in clinical, aetiological and histopathological profile of erythroderma. The present series had high percentage of erythroderma secondary to preexisting dermatoses. The onset of disease was insidious except in drug-induced erythroderma where it was acute.
