A healthy 66-year-old Brazilian man presented with a 10-year history of an asymptomatic mass of nodules affecting his left arm. The lesion had initially appeared as a papule and had been slowly enlarging since then. The patient reported pulling a tick out of the initial lesion. For many years he had been a rubber worker in the Amazon region.
Physical examination revealed 4 ill-defined, smooth, shiny, elastic nodules on the medial aspect of the right arm (Figure 1). A skin biopsy specimen was obtained and stained with hematoxylin-eosin (Figure 2) and Grocott methenamine–silver (GMS) (Figure 3).
