REPORT OF A CASE

A 22-year-old Arabian man presented with a 3- to 4-week history of a painful lesion on his left second finger. The nodule arose 2-weeks after the patient nicked his finger on a knife while slaughtering a lamb during Eid al-Adha, the annual Islamic Feast of Sacrifice.

Physical examination revealed a 1.5-cm, edematous, erythematous nodule on the dorsal distal interphalangeal joint of the left second finger (Figure 1). There was a central overlying yellow crust with associated black dots. There was no lymphangitis or lymphadenopathy, nor were there any additional cutaneous findings. A biopsy specimen was obtained (Figure 2 and Figure 3).
