RESUMO
Hydroa vacciniforme (HV)-like lymphoma is a rare, usually fatal Epstein-Barr virus-driven lymphoproliferative disease affecting children from Asia, Mexico, and South America. Cutaneous manifestations imitate HV, a benign photodermatosis in which systemic symptoms are not observed, and spontaneous regression occurs later in adolescence or young adulthood. We report a case of HV-like lymphoma in a 12-year-old girl, descendent from an ancient Amazon indigenous tribe that, as far as we know, represents the second Brazilian case ever reported in the medical literature.

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.
