title: Oral precancerous and malignant lesions associated with graft-versus-host disease: report of 2 cases.
abstract: The development of secondary malignancies has been recognized as a potential iatrogenic complication in patients who have graft-versus-host disease secondary to bone marrow transplantation. Lymphohematopoietic cancer is most frequent, although solid malignancies have also been reported. We describe 2 patients with graft-versus-host disease who developed oral precancerous and malignant lesions. The first patient, a 24-year-old white man, had erythroplakia of the buccal mucosa that proved to be carcinoma in situ histopathologically. The second patient, a 14-year-old Hispanic boy, developed synchronous cutaneous and lingual squamous cell carcinomas. The current cases and similar sporadic case reports found in the literature highlight the susceptibility of patients with graft-versus-host disease to the development of oral cancer. Therefore, it is recommended that thorough evaluation of the oral mucosa and close follow-up be offered to all patients treated with bone marrow transplantation and particularly to those who develop graft-versus-host disease.
