Goblet cell carcinoid of the appendix. Review of the literature a propos of a rare case of endometrial metastases.

BACKGROUND: Carcinoid tumors are rare tumors most commonly found in the gastrointestinal tract. They represent the most common malignancies of the appendix. As a distinct entity from both adenocarcinomas and carcinoids, Goblet cell carcinoid (GCC) was initially described in the literature in 1969. The GCC is almost exclusive to the appendix, but rarely can be found in rectum, ileum and colon. More than 50% of the patients at the time of diagnosis already have advancedstage disease. The most common metastatic sites are the peritoneal surfaces of the pelvis and abdominal cavity, and ovaries in women. Surgery is the main form of treatment in patients with GCC.

CASE PRESENTATION: A 49-year-old woman was treated at the Institute of Oncology and Radiology of Serbia with histopathological findings of GCC. In a 8-year period the patient was treated with initial appendectomy and three more operations because of locoregional disease progression. The last operation was performed in March 2016 because of endometrial metastases. Since then the patient is on regular follow up without disease progression.

CONCLUSION: GCC is a very rare entity. Multidisciplinary approach is necessary for adequate patient treatment.
