Cancer in buccal mucosa in patients with Fanconi anemia: Report of six cases

Abstract

IntroductionFanconi anemia (FA) is a recessive hereditary disease characterized by bone marrow failure, and the treatment is hematopoietic stem cell transplantation (HSCT). Patients diagnosed with FA are more predisposed to develop oral squamous cell carcinoma (SCC), and this risk increases in transplant patients. The clinical characteristics of the oral manifestations of SCC in this group of patients do not differ from the lesions present in patients without the disease; however, they can be diagnosed in young patients and less common locations, such as, for example, in the buccal mucosa.ObjectiveTo report a case series of patients diagnosed with FA with oral SCC.MethodIncluded in this case series are six patients diagnosed with SCC in the buccal mucosa with similar clinical characteristics.Final considerationsThere are still difficulties in establishing the natural history of oral lesions in patients with FA. Thus, disclosing a series of cases with similar changes may be relevant to improving and refining the multidisciplinary team's clinical view of suspected SCC or oral potentially malignant disorders (OPMD), providing surveillance and timely management.
