Fanconi anemia and hematopoietic stem cell transplant as risk factors for oral squamous cell carcinoma: A case report with a 12-year follow-up.

Fanconi anemia is a rare disorder resulting from defects in genes responsible for DNA damage responses. It is characterized by congenital anomalies, aplastic anemia, and a predisposition to cancer. Currently, hematopoietic stem cell transplant (HSCT) is the only curative treatment available for bone marrow failure; however, HSCT increases oral squamous cell carcinoma (OSCC) risk.
