An unusual clinical course of a hormone-secreting gastrointestinal tumor: a case presentation from clinical practice.
The gastrinoma was first described in 1955 by the surgeons Zollinger and Ellison. The basic characteristic of this disease is an endocrine tumor of the gastrointestinal tract, which secretes gastrin. There is a hypersecretion of gastric juice and recurrent gastric, duodenal and jejunal ulcers. Herein, the case of a 49 year-old female is presented. In 1982, two liver tumors, sized 10 and 6 cm, were discovered in the right and left lobes of the liver, respectively. A duodenal ulcer was also found. During explorative laparotomy, a liver biopsy specimen was obtained and defined pathohistologically as a metastatic, small cell epithelial tumor with an organoid endocrine pattern, morphologically corresponding to tumors of the APUD (Amine Precursor Uptake and Decarboxylation) series. The gastrinoma was verified by immunohistochemical staining. Serum gastrin values exceeded normal values by 10 times. The patient refused further treatment at that time. In the following years, she was treated conservatively several times for sequelae of ulcer disease. For the past three years, she has been treated as an outpatient, mostly for chronic diarrhea.
