A healthy 81-year-old woman presented for further evaluation of a nodule on her right cheek, where she had been stung by a wasp approximately 3 months earlier. The erythema and edema surrounding the sting did not resolve, but persisted and intensified over the following months. The patient's local physician obtained a biopsy specimen, which revealed a dermal infiltrate of atypical mononuclear cells and was initially interpreted as lymphoma. The findings of radiography of the chest, computed tomography of the abdomen and pelvis, and blood studies were unremarkable.
