Clinical findings
A 28‐year‐old man presented with a 6‐month history of acute‐on‐chronic paronychia of his right middle finger. The lesion was mildly tender but not itchy. The proximal and lateral nail folds were grossly swollen, with tiny areas of superficial ulceration. There was slight exudation of yellowish fluid (Fig. 1). The adjacent fingers were normal with intact cuticles. The patient did not have skin lesions elsewhere on his body, and was otherwise in good general health. He worked for the civil defence forces and had visited Bannu, a small city bordering Afghanistan, about 2 months prior to the onset of the finger problem. The lesion had not responded to multiple courses of oral antibiotics including cloxacillin, ampicillin with clavulinic acid, metronidazole, ciprofloxacillin and cephalosporins. Full blood count, baseline liver function tests, urea creatinine, serum calcium and chest X‐ray revealed no abnormality. An X‐ray of the affected finger did not show any bone lesion, and multiple samples for microbial culture did not grow any pathogenic organism.
