Picture of Tick Bite Granuloma

This picture shows an inflamed lump (papulonodular lesion) that has developed on the scalp after a tick bite. The lesion is itchy and scaly. Scratching may result in a secondary bacterial infection. Corticosteroids may be applied topically or injected into the area to decrease itching, pain, and inflammation. A lump like this may persist for several months after a tick bite. Biopsy may be necessary to properly diagnose and treat the lesion.
