Insect Bite with Lymphangitis

David L. Kaplan, MD

A 70-year-old woman was bothered by a pruritic, reddened site on her left shoulder. The lesion progressed with a linear, erythematous eruption leading to her axilla and caused tender adenopathy.

A 70-year-old woman was bothered by a pruritic, reddened site on her left shoulder. The lesion progressed with a linear, erythematous eruption leading to her axilla and caused tender adenopathy.

The patient could not recall being bitten. However, a biopsy of tissue from the lesion confirmed the suspected diagnosis of a reaction to an insect bite with secondary lymphangitis.

A short course of prednisone completely resolved the signs and symptoms of the bite in this patient.
