A Shih tzu with Toxic Epidermal Necrolysis Suspected Histologically Showed the Classic Clinical Course of Erythema Multiforme Minor

Abstract

A 10-year-old, male Shih tzu presented with erythema, erosion, ulcer, crust on the abdomen, axillae, dorsal neck, scrotum, lips, and tongue. Histopathologic examination revealed thick epidermal coagulation necrosis and liquefaction at the hair follicles. All skin lesions of this dog were improved 45 days later without any specific treatments. This dog showed the classic clinical course of Erythema Multiforme Minor, although skin lesions were histologically compatible with those of Toxic Epidermal Necrolysis.
