Case study of appendiceal carcinoid during pregnancy

The carcinoid tumor of the appendix is one of the most common tumors of the appendix, but one of the rarest anatomic locations of carcinoids. The prognosis is very good, as most tumors are incidentally discovered during surgery for acute or sub-acute appendicitis. The diagnosis is exceptional when combined with pregnancy. We present such a case of a 27-year-old female patient. An emergency appendectomy was performed, and soon after, pregnancy was confirmed. The patient had a tumor smaller than 1 cm in diameter, at the tip of the appendix. The immunochemistry revealed the neuroendocrine profile by positive reaction for chromogranin A and synaptophysin, with a ki-67 profile at an undetectable level. After surgery, the neuroendocrine markers and the octreoscan were negative, consequently indicating a favorable prognosis. Further follow-up is necessary, even though not all the authors recommend it (considering the low index to the associated metastases, especially for small appendiceal tumors). A short review of the literature is presented, starting with this case report.
