Primary endometrial squamous cell carcinoma (PESCC) is an uncommon entity, with fewer than 100 cases reported in the English literature. Survival data for PESCC are not well reported and a precise five-year survival rate for PESCC has not been determined. This study focuses on the five-year survival of a 61-year-old patient with PESCC and adds information to an area which is not well documented. The patient was treated by hysterectomy with bilateral salpingo-oophorectomy and assigned to FIGO stage lb. No adjuvant therapy was given. During the 60-month follow-up period, the patient remained free of disease. This outcome suggests that in the early stage of PESCC, surgical treatment alone is adequate to arrest the disease.
