An 86-year-old woman presented with marked blistering of her left index fingertip and ulceration of the left middle fingertip, with a 2-year history of recurrent blistering and ulceration of her fingers bilaterally. She denied any preceding finger trauma, although she reported frequent gardening. She denied systemic symptoms. Her medical history was significant for a 2-year history of atrial fibrillation on carvedilol, amiodarone and apixaban, and she was a lifetime non-smoker. On admission, she had elevated inflammatory markers but unremarkable autoantibodies. Radiograph of the hand revealed diffuse soft tissue fullness and subtle irregularities at the tuft of the index finger, but all other investigations were unremarkable. The lesion was incised and drained, revealing blood-tinged purulent fluid. Wound biopsy revealed spongiosis with neutrophils, consistent with a diagnosis of blistering distal dactylitis.
