BACKGROUND
Extracranial metastases of pineal germinomas are rare.
METHODS
The case of a metastasis of a primary intracranial germ cell tumor via a temporary-ventriculo-peritoneal shunt as a cause of acute abdominal pain is reported. The germ cell tumor markers were useful in establishing the
Testicular tumors are the most common solid tumors in young adult males. Patients with testicular tumor often present with painless scrotal mass. Rarely, symptoms are related to metastases. We describe the case of a patient presenting with abdominal pain due to retroperitoneal lymphadenopathy. We
Inflammatory myofibroblastic tumor is a reactive proliferation of myofibroblasts that rarely involves the urinary bladder. The cause of inflammatory myofibroblastic tumor is unknown but may represent an initial reactive process to an infectious agent or trauma that transforms into neoplastic growth.
Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is characterized by periodic fever, cutaneous rash, conjunctivitis, lymphadenopathy, abdominal pain, myalgia, and arthralgia. It is a rare autosomal dominant disease and strongly associated with heterozygous mutations in the tumor
BACKGROUND
Tumors of the minor papilla of the duodenum are extremely rare, and they are mostly neuroendocrine tumors, such as somatostatinomas and carcinoid tumors. However, true incidence of carcinoid tumors in minor papilla might be much higher, because patients with minor papillary tumors usually
Solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor that accounts for less than one percent of pancreatic tumors. The diagnosis could be challenging as SPN tend to manifest with nonspecific abdominal symptoms, variable radiological features, and inconsistent morphology. The cellular
BACKGROUND
An inflammatory myofibroblastic tumor (IMT) of the small bowel mesentery with diffuse immunohistochemical staining for the anaplastic lymphoma kinase 1 gene is reported in a patient who presented with abdominal pain and uveitis.
CONCLUSIONS
To our knowledge, only seven cases of IMT
Mesenteric tumor emboli have been rarely reported in the literature. Tumors associated with this phenomenon include aortic angiosarcomas, pulmonary neoplasms, Hodgkin's lymphoma, and renal cell carcinoma. In most cases, presentation is dramatic and death is rapid. We present a case of mesenteric
OBJECTIVE
To assess the clinical yield of colonoscoping in patients who present with rectal bleeding, persistent abdominal pain, or change in bowel habits in the absence of bleeding.
METHODS
A prospective study of colonoscopy patients.
METHODS
Three colonoscopy practices in New York City between
Although the adrenal glands are a common site of cancer metastases, they are often asymptomatic and discovered incidentally on CT scan or autopsy. Spontaneous adrenal hemorrhage associated with metastatic lung cancer is an exceedingly rare phenomenon, and diagnosis can be difficult due to its
OBJECTIVE
To analyze the incidence and causes of emergency admission for abdominal pain in patients submitted to radical cystectomy for bladder cancer.
METHODS
A retrospective study was conducted on 176 patients who had undergone radical cystectomy for bladder cancer. The preoperative treatment,
Inflammatory myofibroblastic tumor is a reactive proliferative lesion that occurs extremely rarely in the renal pelvis, especially during childhood. We report 1 such case that occurred in a child who presented with prolonged fever and abdominal pain. Ultrasonography and abdominal computed tomography
Gastrointestinal autonomic nerve tumor (GANT) is extremely rare and considered a variant of gastrointestinal stromal tumors (GISTs). GANT originates from the intestinal autonomic nervous system mostly of small intestine or the stomach. We report a colonic GANT diagnosed in a 5-year-old child who
BACKGROUND
There are a lot of different causes of abdominal pain; in this case, a young woman suffers from three diseases with similar symptoms. Adult intestinal mal-rotation is a rare condition of deviation from the normal 270° counter clockwise rotation of the midgut resulting in, not only
Chronic, refractory abdominal pain without a metabolic or structural gastroenterological etiology can be challenging for diagnosis and management. Even though it is rare, it has been reported that such a recurrent abdominal pain associated with radicular pattern can be derived from structural
