Although the exact mechanism explaining the clinical manifestations of autoimmune pancreatitis remain for an important part obscure, most professionals would agree that the development of IgG4 antibodies, recognizing an epitiope on the membrane of pancreatic ancinar cells is an important factor in the pathophysiology of the disease.
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
Krukenberg tumors often come to the attention when they cause abdominal or pelvic pain, bloating, ascites, or pain during sexual intercourse.Krukenberg tumors can occasionally provoke a reaction of the ovarian stroma which leads to hormone production, that results in vaginal bleeding, a change in menstrual habits, or hirsutism, [3] or occasionally virilization [4] as a main symptom.
A number of types of pancreatic cancer are known. [10] The most common, pancreatic adenocarcinoma, accounts for about 90% of cases, [11] and the term "pancreatic cancer" is sometimes used to refer only to that type. [10] These adenocarcinomas start within the part of the pancreas that makes digestive enzymes. [10]
Enterochromaffin cells, which give rise to carcinoid tumors, were identified in 1897 by Nikolai Kulchitsky and their secretion of serotonin was established in 1953 [105] when the "flushing" effect of serotonin had become clinically recognized. Carcinoid heart disease was identified in 1952, and carcinoid fibrosis in 1961. [105]
Gestational choriocarcinoma is a form of gestational trophoblastic neoplasia, which is a type of gestational trophoblastic disease (GTD), that can occur during pregnancy. It is a rare disease where the trophoblast , a layer of cells surrounding the blastocyst , undergoes abnormal developments, leading to trophoblastic tumors .
It is a disease process characterized by irreversible damage to the pancreas as distinct from reversible changes in acute pancreatitis. [ 5 ] [ 6 ] Tobacco smoke and alcohol misuse are two of the most frequently implicated causes, and the two risk factors are thought to have a synergistic effect with regards to the development of chronic ...
Causes such as bacterial and fungal infections are associated with diffuse abdominal pain, intraperitoneal fluid accumulation, weight loss, fevers, and night sweats. The most common radiographic feature among patients with suspected tuberculous peritonitis was septated compartments of ascitic fluid on ultrasound and abnormal chest X-ray ...
