Die erste Antwort kam heute: "unbekannt".
In der Antwort war ein hinweis enthalten: "Schleimdrüsen". Das hat mich auf das gebracht, was ich vermutet hatte: "muzinöse Neoplasie" ist ein völlig verqueres, verquastes Sprachmischmasch. Mit sowas kann kein normaler Mensch etwas anfangen.
Suche mit Google nach
mucosa neoplasie
also dem Wort für Schleimhaut und neoplasie liefert diese Treffer:

"Appendix" ist Blinddarm. Wenn das stimmt, was Sie schreiben, wurde der Blinddarm entfernt. Okay, der Blinddarm sitzt am Darm. Aber wie paßt der Rest der Beschreibung dazu?

Neoplasms of the Small Intestine, Vermiform Appendix, and Peritoneum
Erik Barquist, MD and Michael Zinner, MD.
Tumors of the Small IntestineIntroduction
The small intestine is the site for almost 90% of the alimentary tract’s mucosal surface area, but it is the site of only a small percentage of intestinal neoplasms, and only rarely is a malignancy found.1 The reasons for this may include the rapid transit of content through the small bowel, local protective mechanisms, or the relative lack of carcinogens in contact with the mucosal surface.2,3 Nonetheless, the tumors of the small bowel are among the most interesting and well studied of those in the gastrointestinal (GI) tract. Recent figures4 show that less than 3% of all alimentary tract tumors and less than 1% of all malignancies arise in the small bowel. Despite this relative rarity, 4,800 new small bowel malignancies were predicted for 1999. In comparison with colorectal cancer (139,400 new cases), it appears that small bowel tumors are 30 times less frequent. If mortalities are compared, then colorectal tumors account for 50 times as much loss of life. Because of this rarity, the clinician must become familiar with the signs and symptoms of small bowel cancers.
Neoplasms of the small bowel have been reported for 250 years5,6 and successful resections for 115 years.7–9
Most small bowel tumors are benign. These tumors include leiomyoma, adenoma, and lipoma, with rare tumors including fibromas, fibromyxomas, neurofibromas, ganglioneuromas, hemangiomas, and lymphangiomas. The malignant tumors include adenocarcinoma, carcinoids, lymphomas, sarcomas and their subtypes, and other rare tumor types, such as Kaposi’s sarcoma, seen primarily in patients with end-stage human immunodeficiency virus (HIV) infection.
Many small bowel tumors are asymptomatic until late in their course due to their relatively slow growth and the ease with which the contents of the small bowel can pass even a partially obstructing lesion. Half of small bowel cancers are found only at autopsy. The remainder are usually found as a result of the symptoms of partial obstruction: nausea and vomiting if the lesion is proximal; crampy abdominal pain; or other nonspecific findings such as weight loss. Hemorrhage is frequently found in those tumors that penetrate beyond the submucosa but almost always is occult, presenting as stool that is positive on guaiac testing and microcytic anemia. Eventually, malignant tumors cause enough symptoms for the ensuing medical work-up to reveal the tumor. Unfortunately, some time may pass between the first symptom and diagnosis. In one series, almost one-third of the patients had had symptoms for 5 years or more prior to definitive diagnosis.10 A more recent study demonstrated a median duration of symptoms of 8 months prior to diagnosis.11 Many patients eventually diagnosed with small bowel tumors present as an emergency with either bowel obstruction or perforation.
The diagnosis of these lesions is usually accomplished with the aid of radiographic studies. Only 25% of patients present with a palpable mass; another 25% have the symptom of abdominal distention, secondary to obstruction. Plain films of the abdomen are unlikely to be of use, except to demonstrate the presence of obstruction or perhaps displacement of the bowel by a mass. Contrast studies show about one half of these tumors, although, with retrospective readings, up to 75% of small bowel tumors can be found. Some studies have reported even higher rates of diagnosis by barium study.12 More recently, duodenal tumors have been diagnosed using endoscopy, and the advent of computed tomographic (CT) scanning with oral contrast has led to nearly 100% recognition of small bowel tumors in some series.13 Others disagree with this view and hold that a small bowel series is the best radiographic study.14 Angiography and nuclear scanning may be useful in the case of a bleeding tumor or a suspected hemangioma.
The treatment of small bowel tumors is usually surgical, with simple resection for benign lesions and an aggressive approach for malignant lesions. Overall, the survival for adenocarcinomas, carcinoids, lymphomas, and sarcomas was better in 328 cases from a population-based registry than that for all other organs, except the breast, colon, prostate, and uterus.15 In most cases, the surgical resection must include wide margins, resection of lymph nodes, and removal of the supporting mesentery. Lymphadenectomy is usually not performed for leiomyosarcoma due to its lack of lymphatic metastases. In rare cases, radiation or chemotherapy may precede surgery. Duodenal tumors may require pancreaticoduodenectomy if malignant, whereas tumors of the terminal ileum may require right hemicolectomy to ensure complete resection and adequate margins.
Endocrine tumors of the gut, also known as carcinoid tumors of the gut, may present with their own set of classic symptoms, such as flushing, diarrhea, cyanosis, and intermittent respiratory distress. Only a small proportion of patients with carcinoid tumors have these symptoms, the vast majority being asymptomatic or having symptoms secondary to mass lesion effects.

Bitte unbedingt das Original ansehen. Der Text ist SEHR lang!!!
Das Alter des Textes darf man aber auf gar keinen Fall übersehen: mehr als 10 Jahre. Die Frage ist nämlich, was es inzwischen an neuem Wissen gibt.
