ORAL SQUAMOUS CELL CARCINOMAS IN PATIENT WITH GRAFT VERSUS-HOST DISEASE FOLLOWING ALLOGENIC BONE MARROW TRANSPLANTATION. A CASE REPORT DURING MUTANT COVID-19 PANDEMIC

Aplastic anaemia is a severe haematological disorder characterized by an inadequate number of hematopoietic stemcells, resulting in pancytopenia, formed by a hypocellular bone marrow. Disorders of this nature are widely treatedwith haematopoietic stem cell transplantation (HSCT). A potential chronic complication following (HSCT) is thegrowth of secondary malignancies. Notably, patients suffering from chronic graft versus host disease (cGvHD) secondary to HSCT have been shown to be more susceptible to oral squamous cell carcinoma (OSCC). Here, we present a rare case of a 30-year-oldLibyan woman treated with HSCT for aplastic anaemia, with subsequent complications of cGvHD and OSCC after few months of HSCT. These carcinomatous lesions were detected in the buccalgingiva and retromolar pad area at age of 31. The present case report emphasizes on the connection between oralcGvHD and OSCC, and the potential appearance of OSCC after HSCT at any time of patient life. Thus, closer follow-up is mandatory for all patients treated with HSCT who developed cGvHD, and efficient cGvHD preventionand therapeutic approaches are needed
