A case of goblet cell carcinoid of the appendix]

A rare case of goblet cell carcinoid of the vermiform appendix is presented. A 71-year-old man was seen at the hospital because of right lower abdominal pain. Appendectomy was performed with a preoperative diagnosis of acute appendicitis. However, histological examination revealed a goblet cell carcinoid tumor of the appendix (ss, ly1, v0). A subsequent right hemicolectomy with lymph node dissection was carried out. No residual lesion or lymph node metastasis was identified in the specimen. At his 1-year postoperative evaluation, the patient was asymptomatic. Goblet cell carcinoid of the appendix has been histologically classified as a variant of carcinoid tumor, however, it is potentially malignant and it should be recognized as a variant of adenocarcinoma. Therefore, aggressive surgical treatment is necessary.
