A cohort of nine patients, mostly young adults, presented with a new sign/symptom of pheochromocytoma/paraganglioma: exercise-induced nausea and vomiting. The aims of this article are to introduce this sign/symptom and offer a possible hypothesis for the observation. Following a 2000 report from a
A case of nonfunctional benign preaortic paraganglioma is reported. The patient, a woman aged 50, complained of vague mesogastric pain irradiated posteriorly, occasional nausea and vomiting, related to a tender pulsatile mesogastric mass fixed to the posterior wall of the abdomen. Preoperative
Vaginal paraganglioma is a rare and unusual tumor occurring in the vaginal wall. It is a solitary primary paraganglioma, especially in atypical sites. Herein, we report an unusual case of a 17-year-old woman who had not experienced vomiting, or hypertension. She was found to have an immobile solid
Objective: Functional paragangliomas in pregnancy are rare; however, if not recognized and treated early, they can be life-threatening. New treatment approaches with robotic resection are promising.
Gangliocytic paraganglioma (GPG) with local lymph node metastasis was found in the pancreas of a 74-yr-old female who presented with diarrhea, steatorrhea, vomiting, nausea, and abdominal pain. A Whipple procedure led to a complete resolution of these symptoms and a return of an elevated
A 7-year-old male intact Rottweiler was presented with a 1-week history of lethargy, anorexia, vomiting and multiple syncopal events. The results of the clinical examination and electrocardiography were consistent with a third degree atrioventricular block and an intermittent accelerated
A 60-year-old female was evaluated for significant weight loss, nausea, vomiting, and dysphagia. A computed tomography (CT) of the chest showed a 3 cm mass in the middle mediastinum. CT scan of the abdomen and pelvis revealed no abnormality. Positron emission tomography (PET) of the whole body
Our experience with [131I]metaiodobenzylguanidine (131I-MIBG) therapy in a 10 year old boy is reported. At disease onset, in May 1988, this boy presented a large mass in the upper left abdominal quadrant, which was resected with a histopathological diagnosis of extra-adrenal malignant
A 9-year-old sterilised female domestic short-hair cat was referred with a history of vomiting and anorexia of 3 months' duration. Biochemistry, full-blood counts, thoracic radiographs, feline pancreatic-specific lipase, abdominal ultrasonography and feline immunodeficiency virus/feline leukaemia
1p36 deletion syndrome is the most common terminal deletion syndrome, and the genomic regions that contribute to specific 1p36 deletion syndrome-related phenotypes were recently identified. Deletions in the 1p36 region have been documented in various tumor tissues, which indicates correlation
Several studies have shown that patients with succinate dehydrogenase subunit B (SDHB) mutations have a very high risk for developing malignant paragangliomas. However, there is no consensus of what age screening for paragangliomas should start. We report a case of an 8-year-old white girl with a
A 20-year-old woman died suddenly in a hospital emergency room after presenting with nausea, vomiting, back pain, and hypertension. At autopsy, an extra-adrenal pheochromocytoma (paraganglioma) of the organs of Zuckerkandl was found, with microscopic focal myocardial necrosis similar to that
CONCLUSIONS
We report a case of a duodenal gangliocytic paraganglioma that had an unusual clinical presentation and atypical immunohistochemical features.
BACKGROUND
Duodenal gangliocytic paragangliomas are rare tumors of the gastrointestinal tract with approx 70 cases reported in the literature.
Mesenteric paraganglioma is a solitary primary paraganglioma that occurs in the mesentery. It is a rare and unusual tumor, especially in non-typical sites such as the inferior mesenteric artery. We incidentally diagnosed a pelvic mass in a 22-year-old woman, who had not experienced vomiting,
Paragangliomas are very rare tumors derived from neuroendocrine cells of autonomic nervous system. Extra-adrenal paragangliomas account for only 10 to 15% of all paragangliomas and may present incidentally as a mass. Typical triad of fluctuating hypertension, headache, and sweating is not always
