A Case of Primary Upper Esophageal Small Cell Cancer with Cervical Lymph Node Metastasis / 대한소화기내시경학회지

ABSTRACT

Esophageal small cell carcinoma is a very rare disease. Primary extra-pulmonary small cell carcinoma was reported to account for 4% of primary small cell carcinoma and only 2% of all esophageal malignancy. Because the rate of early distant metastasis is very high, the prognosis is very poor. In Korea, 20 cases were reported. Seventeen cases were located at the mid or lower esophagus and 3 cases were located at the upper esophagus. We have experienced a case of primary upper esophageal small cell cancer, a 65-year-old female with cervical lymph node metastasis, which were diagnosed by endoscopy, open surgical lymph node biopsy and immunohistochemical analysis.
