Abstrakt: Introduction: Close clinical inspection for intraoral lesions in patients with leukemia that develop chronic graft-versus-host disease (cGVHD) is critical. Additionally, neoplasias developing in bone marrow transplant patients after treatment for leukemia represent a significant obstacle for long-term patient survival, necessitating lifetime follow-up by health care providers. This case report describes the identification, diagnosis, and treatment of gingival squamous cell carcinoma (SCC) in a patient with leukemia who was treated previously with a stem cell transplant and referred for routine periodontal care.
Case Presentation: A 53-year-old male was referred to the Department of Periodontics for an assessment of tooth #10 with 2+ mobility and associated cross-bite occlusion. The patient was diagnosed with acute myeloid leukemia at age 39 years, received hematopoietic stem cell transplantation (HSCT), and later developed cGVHD followed by human papilloma virus (HPV) infections. During the periodontal evaluation, a large, non-painful, exophytic, alveolar gingival mass was identified and later diagnosed as SCC. It is unusual that oral SCC presents as an exophytic, gingival swelling. The patient received comprehensive periodontal management in coordination with his otolaryngology team before and during the diagnosis of SCC secondary to cGVHD and HPV infection.
Conclusions: Patients with a history of HSCT treatment for leukemia and subsequent cGVHD are at a high risk of developing second primary oral malignancies, including SCC. Exposure to oncogenic HPV infection may compound this risk. Therefore, it is important for dentists to be aware of special treatment concerns and to frequently screen these patients to achieve early diagnosis and treatment of these neoplasms.
