Plasma cell orificial mucositis (PCOM) is a very rare, benign plasma cell proliferative condition with an unknown etiology. It is generally reported in adults and elderly patients, and it is typically characterized by erythematous mucosa with varying degrees of surface changes. The purpose of this case report is to present clinical findings for an 11-year-old male patient recently diagnosed with PCOM after biopsy. The patient reported bleeding upon brushing with no pain. He presented with erythematous tissue that had a strawberry-red appearance limited to the keratinized gingiva of the facial tissue. The patient’s medical history is also significant for Fanconi anemia with a history of bone marrow transplant. Less than 50 cases have previously been reported in the literature, and only two other cases have been reported in pediatric patients. This report represents the third known case to be reported for a pediatric patient.
