Goblet Cell Carcinoid

Adenocarcinoma ex goblet cell carcinoid is a rare tumor incidentally found in specimens of appendicitis. Most patients present with acute abdomen, similar to acute appendicitis. Here we present two cases, which were found incidentally after operation. We give a brief summary about clinical and biological behavior of this entity.

Abstract Acute appendicitis is the most common surgical pathology worldwide, frequently, the patient history and clinical examination are so similar to other appendicular pathologies that preoperative diagnosis is almost impossible for the medical team. Neuroma of the appendix is a rare tumor of neural origin that usually resembles the symptoms of acute appendicitis. Pathology along with close follow-ups are key, as the diagnosis is based on the presence of nerve neuronal cells in the appendicular lumen. Surgical treatment is recommended due to the possibility of malignancy. We present a case of a 32-year-old male patient who presented with symptoms of acute abdomen, surgery was performed and appendectomy was completed. Neuroma of the appendix was the final diagnosis.

In Pregnancy

Acute appendicitis is the most common acute surgical infection during pregnancy. Although usually pyogenic in origin, parasitic infections account for a small percentage of cases. Despite the relatively high prevalence of acute appendicitis in our environment, it is not commonly associated with schistosomiasis. We report here the association of pregnancy and appendicitis caused by Schistosoma haematobium. Schistosomiasis is very common complication of pregnancy in hyperendemic areas. Schistosome egg masses can lodge throughout the body and cause acute inflammation of the appendix, liver and spleen. Congestion of pelvic vessels during pregnancy facilitates passage of eggs into the villi and intervillous spaces, causing an inflammatory reaction. Tourism and immigration make this disease a potential challenge for practitioners everywhere.

Summary Aim: Even with careful observation, the overall false-positive rate of laparotomy remains 10-15% when acute appendicitis was suspected. Therefore, the clinical efficacy of Tc-99m HMPAO labeled leukocyte (TC-WBC) scan for the diagnosis of acute appendicitis in patients presenting with atypical clinical findings is assessed. Patients and Methods: Eighty patients presenting with acute abdominal pain and possible acute appendicitis but atypical findings were included in this study. After intravenous injection of TC-WBC, serial anterior abdominal/pelvic images at 30, 60, 120 and 240 min with 800k counts were obtained with a gamma camera. Any abnormal localization of radioactivity in the right lower quadrant of the abdomen, equal to or greater than bone marrow activity, was considered as a positive scan. Results: 36 out of 49 patients showing positive TC-WBC scans received appendectomy. They all proved to have positive pathological findings. Five positive TC-WBC were not related to acute appendicitis, because of other pathological lesions. Eight patients were not operated and clinical follow-up after one month revealed no acute abdominal condition. Three of 31 patients with negative TC-WBC scans received appendectomy. They also presented positive pathological findings. The remaining 28 patients did not receive operations and revealed no evidence of appendicitis after at least one month of follow-up. The overall sensitivity, specificity, accuracy, positive and negative predictive values for TC-WBC scan to diagnose acute appendicitis were 92, 78, 86, 82, and 90%, respectively. Conclusion: TC-WBC scan provides a rapid and highly accurate method for the diagnosis of acute appendicitis in patients with equivocal clinical examination. It proved useful in reducing the false-positive rate of laparotomy and shortens the time necessary for clinical observation.

SummaryMedullary carcinoma of the thyroid gland is a rare tumor. Its prognosis is mainly linked to surgery, because there is no valid alternative therapy to improve patients outcome. In this report, we discuss the recurrence of such a tumor in a 64-year-old female, focusing on magnetic resonance imaging and positron emission tomography evaluation of this tumor.
