A case of tuberculous lymphadenitis with erythema nodosum

Abstract

Sir, Erythema nodosum (EN), a painful disorder of the subcutaneous fat, is the most common type of panniculitis. Generally, it is idiopathic, although the most common identifiable cause is streptococcal pharyngitis. EN may be the first sign of a systemic disease such as tuberculosis (TB), bacterial or deep fungal infection, sarcoidosis, inflammatory bowel disease, or cancer. Certain drugs, including oral contraceptives and some antibiotics, also may be etiologic. We present a case of tubercular lymphadenitis with EN.
