Swan-neck deformity and paresthesia following giant orf.

Orf is a zoonotic infection caused by a parapoxvirus that primarily infects sheep and goats. Human orf infection can take place when abraded skin comes into contact with infected animals. It occurs most commonly on the index finger. The characteristic lesion resembles a tumor and resolves spontaneously, usually without any complications. However, rare complications such as lymphangitis, adenitis, erythema multiforme, erysipelas, papulovesicular eruption, Pseudomonas aeruginosa infection, and bullous pemphigoid have been reported. Herein, we report a case of giant orf causing swan-neck deformity and paresthesia. These complications have not been previously reported in the literature.
