ObjectiveTo explore the clinical features and treatment of nasal basaloid squamous cell carcinoma(BSCC),so as to improve the diagnosis and treatment of this disease.MethodsIt was retrospectively analyzed for the clinical data of one case of BSCC treated by surgery in February 2017. The patient(female, 69 years old) was admitted to hospital because of the progressive enlarged mass of the paranasal on the right side for 4 months,which was confirmed by preoperative biopsy as BSCC.On February 15,2017, the patient underwent tracheotomy,cervical lymph node selective clearance (Zones I、Ⅱ、III) and resection of parnassal malignant tumor on the right side.And also the patient was performed partial maxillary resection and forearm flap transplantation and repair.The family members refused the radiotherapy of the patient after the surgery.ResultsAfter close followup of 32 months,the wound healed well without recurrence or metastasis.ConclusionsBSCC is a rare and highly malignant tumor with unique pathological morphology and poor prognosis. Surgical treatment is the first choice for BSCC, which is supplemented by radiotherapy after operation with close followup.
