Basaloid cell carcinoma originating in the esophagus is a rare disease classified as an epithelial malignancy. Compared ith squamous cell carcinoma, basaloid cell carcinoma of the esophagus is generally associated with poor prognosis, involvng extensive vascular invasion and causing extensive lymph node and hematogenous metastases. A 69-year-old male patient ad no chief complaint. An elevated lesion was found in the esophagus in the upper gastrointestinal contrast examination erformed as part of the health checkup. A 10-mm-diameter nodular, elevated lesion slightly dented at the center was found t 34 cm from the incisor in esophageal endoscopy. The histological examination of a biopsy specimen revealed cancer cells esembling poorly-differentiated squamous cell carcinoma. cStage I esophageal cancer (Lt 0-IIa, T1bN0M0) was diagnosed nd surgically removed. The patient underwent a subtotal esophagectomy with two regional lymph nodes (thoracic lymph des and abdominal lymph nodes) dissection via a right thoraco-laparotominal approach and reconstruction of the esophaogastric tube anastomosis at the upper mediastrium area. The histopathology of the removed sample showed squamous ell carcinoma in the superficial epithelium and non-invaded part. The tumor cells had invaded the upper submucosal layer nvolving basaloid cell carcinoma. Based on the findings, superficial basaloid cell carcinoma of the esophagus was diagsed (pT1b pN0 pM0 ly0 v0 pStage I). The patient had a good postoperative course and was discharged at about 3 weeks fter surgery. No adjuvant chemotherapy has been performed. Currently at about 4 years postoperation, the patient is being ollowed up on an outpatient basis without recurrence.
