Orf on the ear', in a patient with Guillain-Barré Syndrome.

Autor(es): Singh Daram; Kumarasinghe Sujith Prasad

Resumo: We report a case of orf on an ear in a patient admitted to hospital following the onset of Guillain-Barré syndrome. While the underlying causes of Guillain-Barré syndrome are not completely understood, immune stimulation appears to play a key role in pathogenesis. Any association between orf infection and Guillain-Barré syndrome has not been documented. A 22-year-old male sheep farmer, who was previously fit and well, presented to his local hospital with a 2-day history of distal upper and lower limb paraesthesia and weakness. He was transferred to a tertiary hospital where the diagnosis of Guillain-Barré syndrome was confirmed. History revealed that he had experienced a mild respiratory illness 3 weeks prior to presentation and an inflamed nodular lesion over his left ear, which had appeared 2 weeks prior to admission. Differential diagnoses of orf, atypical mycobacterial infection, subcutaneous mycosis and a squamous cell carcinoma were considered. Histopathology from a biopsy of the lesion was consistent with orf, which was confirmed by polymerase chain reaction testing. This case is of interest for two reasons: orf has not been described in association with Guillain-Barré syndrome, and orf on the ear is uncommon.
