The diameter can range from a few millimeters to more than 30 cm. Larger tumors usually cause symptoms in contrast to those found incidentally which tend to be smaller and have better prognosis. [ 4 ] [ 20 ] Large tumors tend to exhibit malignant behavior but small GISTs may also demonstrate clinically aggressive behavior.
Common norovirus symptoms. Many associate the stomach flu with gastrointestinal issues that can make everyday life (and even eating!) feel impossible, causing immense pain for days on end.
Lymphomas and mesenchymal tumors may also develop in the stomach. [2] Early symptoms may include heartburn, upper abdominal pain, nausea, and loss of appetite. [1] Later signs and symptoms may include weight loss, yellowing of the skin and whites of the eyes, vomiting, difficulty swallowing, and blood in the stool, among others. [1]
When present, symptoms usually relate to painless bleeding, with vomiting blood (hematemesis) and/or black stools . [3] Less often, Dieulafoy's lesions may cause rectal bleeding (hematochezia), or rarely, iron deficiency anemia. Usually, there are no gastrointestinal symptoms that precede the bleeding (abdominal pain, nausea, etc.).
Differential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. of the arm). Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkin's lymphoma.
AAH is a pre-malignant cause of nodular GGO and is more commonly associated with lower attenuation on CT and smaller nodule size (<10 mm) compared to adenocarcinoma. [10] In addition, AAH often lacks the solid features and spiculated appearance that are often associated with malignant growths. [9]
Primary gastric lymphoma (lymphoma that originates in the stomach itself) [1] is an uncommon condition, accounting for less than 15% of gastric malignancies and about 2% of all lymphomas. However, the stomach is a very common extranodal site for lymphomas (lymphomas originate elsewhere and metastasise to the stomach). [2]
Gastrinoma in the early stages will have signs and symptoms of indigestion [3] or similar to irritable bowel disease (IBD) such as: Hypergastrinemia [3] Refractory or recurrent peptic ulcers involving duodenum [3] Chronic diarrhea [7] [2] [3] Generalized cancer symptoms; Abdominal pain [3] Gastrointestinal bleeding [3] Obstruction of intestine [8]
