Squamous cell carcinoma of the lip after allogeneic hemopoietic stem cell transplantation

ABSTRACT

Allogeneic hemopoietic stem cell transplantation [HSCT] has been considered a curative treatment option for many hematological and non-hematological disorders. Despite the use of advanced methods of tissue typing and new therapies, graft versus host disease [GVHD] remains a major obstacle. Secondary malignancies are also among the most serious long-term complications after HSCT including leukemia, lymphomas, and to a lesser extent, solid tumors. The most commonly observed solid tumor is squamous cell carcinoma [SCC]. We report two cases of SCC of the lower lip diagnosed several years after HSCT. Both cases were complicated with GVHD prior to the development of SCC and had a successful outcome with minimal surgical intervention
