Sarcomatoid carcinoma of the jejunum with gastric metastases: A case report and review of the literature

INTRODUCTION: Sarcomatoid carcinoma (SCA) of jejunum is an extremely rare condition. To our knowledge, only 17 cases have been reported in the literature. PRESENTATION: We introduced an additional case of the sarcomatoid carcinoma of jejunum in a 62-year-old Chinese male who presented with epigastric pain for 3 weeks. Multiple tumors originated in the jejunum and metastases to mesentery lymph nodes and distal stomach were found during the laparotomy. The patient underwent palliative resection of the tumors. He died 11 days after the operation. DISCUSSION: Sarcomatoid carcinoma (SCA) of jejunum is an extremely poor prognostic tumor in human being. The diagnosis of SCA was based on pathological observations and immunohistochemical staining. There is no official treatment guideline for SCA, but wide excision including the tumor is the main goal of treatment. CONCLUSION: This is the first case of sarcomatoid carcinoma of jejunum with gastric metastases being reported and also the shortest survival period after the operation. Surgery is the cornerstones of treatment but the ideal means is still unknown due to the short survival and inadequate reports.
