AbstractA 10‐year‐old Guatemalan girl with past medical history of Epstein‐Barr virus‐associated smooth muscle tumors (EBV‐SMT) and combined immunodeficiency presented for evaluation of painful intraoral lesions. On examination, she was noted to have multiple, white to flesh‐colored, soft, flat‐topped papules, and plaques on the buccal and labial mucosa. Human papillomavirus type 13 was detected on PCR with PGMY primers of previously biopsied buccal tissue, confirming a diagnosis of Heck's disease (multifocal epithelial hyperplasia). We present an immunosuppressed, pediatric patient with two rare, virus‐associated neoplastic disorders that have not been previously reported to occur in the same individual.
