Toxic epidermal necrolysis in a monkey (Macaca fascicularis).

An adult male Macaca fascicularis monkey developed toxic epidermal necrolysis after ingestion of methylmercury. The clinical picture was characterized by the development of large cutaneous bullae with subsequent full-thickness epidermal exfoliation. Areas of sparse pelage were most affected, with the most severe exfoliation occurring on the palms, soles, face and ears. Erosions also developed within the oral mucosa and conjunctivae.
