Abstract

Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient's history of pencil tip injury and histological examination findings.
