RESUMO
Mucormycosis is a rare, fulminating, opportunistic fungal infection that occurs almost exclusively in immunocompromised hosts such as patients with diabetes, leukemia, lymphoma. These fungi are ubiquitous in nature, and can be found on decaying vegetation and in the soil. So they are relatively frequent contaminants in the clinical microbiology laboratory. Recently the incidence of mucormycosis is rising associated with the increasing use of immunosuppressive agents, antibiotics. Though mucormycosis is frequently fatal, there has been a significant improvement in the outcome by early diagnosis and aggressive treatment. Mucormycosis can be categorized as rhinocerebral, pulmonary, gastrointestinal, cutaneous, widely disseminated and miscellaneous; gastro-intestinal involvement is extremely rare. We report a patient with gastric mucormycosis who had diabetes mellitus and alcoholic hepatitis. His chief complaint was an epigastric pain, and the gastroscopy showed huge multiple ulcers, coated with exudates. The histologic examination revealed multiple broad, nonseptate hyphae with right angle branchings, diagnosed as mucormycosis.

Somatostatin analogue octreotide is commonly used for the treatment of carcinoid syndrome. Octreotide also has an antiproliferative effect in neuroendocrine tumors and has demonstrated tumor reduction in patients having advanced carcinoid tumor. This is a case report of a patient who had metastatic liver carcinoid tumor and showed marked regression of liver metastasis after octreotide therapy.

Gastritis cystica profunda (GCP) is a rare disease which is mainly observed at the site of gastroenterostomy. However, it may occur in the stomach without a previous history of surgery. Under histologic examination GCP shows hyperplastic and cystic dilatation of the pseudopyloric glands with submucosal invasion. GCP with sessile polypoid pro-trusion is most commonly found but, submucosal tumors, giant gastric mucosal folds and pedunculated forms are occasionally found. We present the case of GCP showing a large sized polyp (3 2.5 2.5 cm) with a long pendulous pedicle that had developed in the fundus of the stomach without previous surgical history. Endoscopic polypectomy was performed for confirmation.

Gastric leiomyoblastoma is an uncommon intramural tumor, Its been regarded as a tumor of smooth muscle origin by its histological and electronmicroscopic characteristics. However, recent immunohistochemical staining techniques have shown that tumors diagnosed as leiomyoblastoma may have different tumor origins. We report a case of multiple leiomyoblastoma of the stomach thought to be of unknown derivation by Immunohistochemical study.

Multiple primary cancer is defined as the case of primary malignant tumors of different histologic origins each other in one person, The incidence of multiple primary cancer has been increasing recently due to more developed diagnostie procedure and long survival of cancer patients. In esophageal cancer patients, comibined prevalence of other malignancy is rela tively high. We have experienced three cases of gastric adenocarcinoma with esophageal squamous cell carcinoma and report these cases with a review of literatures.

The double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb. Some investigators postulate that the doubling of the pyloric channel is a congenital phenornenon, but others believe that it is an acquired lesion. A 72 year-old-man was admitted to this hospital because of epigastric pain for 1 month. Upper G-I series revealed thickened rnucosal folds of pylorus and duodenal bulb and dilated, deformed duodenal bulb filled with barium materials. Endoscopic findings also showed two ovoid large openings of the pyloric channel divided by smooth thickened septum and multiple gastroduodenal ulcers. We thought that this case was an acquired lesion. The relevant literatures on the subject were reviewed.
