The standard treatment option for patients with inherited pheochromocytoma is surgery.. The surgical management of pheochromocytoma in patients with the hereditary syndromes multiple endocrine neoplasia type 2 (MEN2) and von Hippel-Lindau (VHL) disease has been controversial. In both of these syndromes, pheochromocytoma is bilateral in at least 50% of patients; however, malignancy is very uncommon. Bilateral total adrenalectomy commits all patients to lifelong steroid dependence, and up to 25% of patients will experience Addisonian crisis (acute adrenal insufficiency). [3] [4]. Current recommendations generally favor preservation of adrenal cortical tissue in patients with MEN2 and VHL syndromes when possible. Patients who initially present with unilateral pheochromocytoma should undergo unilateral adrenalectomy, and patients who present with bilateral pheochromocytomas or who develop pheochromocytoma in their remaining adrenal gland should undergo cortical-sparing adrenalectomy, when ...

The authors report a case of the safe performance of radiofrequency (RF) ablations and biopsies in a patient with metastatic pheochromocytoma. The patient had previously undergone RF ablation at another institution for a tumor in her liver; that procedure was complicated by a hypertensive crisis and cardiac arrest. Our experience emphasizes that, despite a prior life-threatening complication, careful pre-, intra-, and postprocedural care to avoid a hypertensive crisis allowed safe RF ablations and biopsies in a patient with pheochromocytoma.

Embolization therapy. Embolization therapy is a treatment to block the artery leading to the adrenal gland. Blocking the flow of blood to the adrenal glands helps kill cancer cells growing there.. Targeted therapy. Targeted therapy is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Targeted therapies are used to treat metastatic and recurrent pheochromocytoma. Sunitinib (a type of tyrosine kinase inhibitor) is a new treatment being studied for metastatic pheochromocytoma. Tyrosine kinase inhibitor therapy is a type of targeted therapy that blocks signals needed for tumors to grow. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website.. Treatment for pheochromocytoma and paraganglioma may cause side effects.. For information about side effects caused by treatment for cancer, see our Side Effects page.. Patients may want to think about taking part in ...
Bilateral pheochromocytomas, the leading diagnosis in our cohort, are known to have familial and/or syndromic association. In a study of 314 patients, Amar and coworkers reported significantly greater familial and/or syndromic association (31/41, 75.6%) in patients with bilateral pheochromocytomas, compared with those with unilateral pheochromocytomas (49/223, 21.9%) (13). Similarly, two-thirds (14/21) of our index patients with bilateral pheochromocytomas had familial/syndromic association. Diagnosis of pheochromocytoma could be made biochemically as all, except two, had evidence of catecholamine excess. These two patients with histopathologically proven diagnosis had normal urinary VMA. This exemplifies the well-described lower sensitivity of urinary VMA compared with that of PFMN and PFNMN (64% vs 100%) (14).. Adrenal tuberculosis was the second leading diagnosis in our cohort. The mean adrenal size in our cohort was 2.1±0.7cm (range 1.0-4.0cm) and 10 patients (52.6%) had evidence of adrenal ...
Pheochromocytoma is a rare tumor of the adrenal gland. It often presents with the classic triad of headache, palpitations and generalized sweating. Although not described as a typical symptom of pheochromocytoma, anxiety is the fourth most common symptom reported by patients suffering of pheochromocytoma. We report the case of a 64 year old man who had severe anxiety and panic disorder as presenting symptoms of pheochromocytoma. After 13 years of psychiatric follow-up, the patient was diagnosed with malignant pheochromocytoma. After surgical resection of his pheochromocytoma and his hepatic metastases, the major panic attacks completely disappeared, the anxiety symptoms improved significantly and the psychiatric medications were stopped except for a very low maintenance dose of venlafaxine. We found in our cohort of 160 patients with pheochromocytoma 2 others cases of apparently benign tumors with severe anxiety that resolved after pheochromocytoma resection. These cases highlight that ...
ONE of the known causes of hypertensioll is a pheochromocytoma, a tumor of the medullary portion of the adrenal gland that secretes epinephrine or norepinephrine in varied but increased amounts. It produces either sustained hypertension or paroxysmal hypertension frequently associated with bizarre symptoms during the attack, together with hypermetabolism and high blood sugar in some instances. Although pheochromocytoma is rare, it is being diagnosed oftener and will beconle inereasingly important with safe surgical renmoval. Thus the correct preoperative diagnosis becomes imperative and can sometimes be lifesaving. An estimated 90 per cent of pheochromocytomas arise from the adrenal medulla, but they may occur wherever chromaffin tissue is found along the sympathetic nervous systein. Of pheochromocytomas found outside the adrenal glands, 6 have been found in the thorax, 4 in the urinary bladder, and 18 in the organ of Zuekerkandl. Multiple tumors may occur in both adrenal glands or along the aorta in
A 32-year-old woman, primigravida, who was 12 weeks pregnant, initially consulted a practitioner with awareness of right abdominal discomfort. She was pointed out bilateral adrenal tumor by abdominal ultrasonography. She was diagnosed with pheochromocytoma by blood examination and consulted our hospital. There were no signs of preeclampsia. Her other past history were unremarkable. A physical examination showed a temperature of 35.7°C and a respiratory rate of 16 breaths/min. Her blood pressure was 129/90 mmHg and pulse rate was 86 beats/min. Her heart and breath sounds were normal. The size of her uterus was consistent with 12 weeks of gestation and fetal heart rate was 148 beats/min. There were no palpable masses in the thyroid, no uterine contractions, and no edema was detected. Major laboratory findings included a hematocrit of 38.8% and white blood cell count of 8,100/mm3, with 72.0% neutrophils and the platelet count was 391,000/mm3. The blood sugar level in the fasting was 87mg/dl. ...

When undetected, pheochromocytoma can maim or kill. Therefore, infrequent as the disease may be, accurate, safe, and feasible screening to find these tumors remains an important goal for the primary care physician, the clinical researcher, and the subspecialist alike. This crucial need is addressed by Lenders and colleagues in this issue [1]. Excess catecholamines released into the circulation by a pheochromocytoma cause the clinical manifestations of the disease. Increased plasma concentrations of norepinephrines or epinephrines or both are found in most but not all patients with these neoplasms. However, high plasma concentrations of catecholamines may be found in other disorders, and the limited sensitivity and specificity of measurement of plasma catecholamines for diagnosis of pheochromocytoma has been well established [2, 3 ...

Three previous case reports have described hemodynamic abnormalities precipitated or triggered by imipramine therapy and leading to recognition of pheochromocytoma (1-3). It has been uncertain whether therapy with other tricyclic antidepressants may unmask pheochromocytoma. We describe the unmasking of pheochromocytoma by desipramine therapy in a patient who showed no adverse effect while receiving amitriptyline intermittently over 9 years.. A 56-year-old woman presented with a history of severe headache and nausea with vomiting for 2 days. Her symptoms had begun after two doses of desipramine (Norpramin, Merrell-National Laboratories, Cincinnati, Ohio), 25 mg, and ketoprofen (Orudis, Poulenc, Ltd., Montreal, Quebec, Canada). She ...

Phaeochromocytoma are a rare clinical entity in children. Contrary to traditional teaching which suggested that 10% of phaeochromocytomas are familial, advances in molecular genetics have revealed an identifiable germ line mutation in up to 59% (27/48) of apparently sporadic phaeochromocytomas presenting at 18 years or younger and in 70% of those presenting before 10 years of age. The inherited predisposition may be attributable to a germ line mutation in the Von Hippel Lindau (VHL) gene; the genes encoding for the subunits B and D of succinate dehydrogenase (SDHB and SDHD); the RET proto-oncogene predisposing to Multiple Endocrine Neoplasia Type 2 (MEN2) or the Neurofibromatosis Type 1 (NF1) gene.1 Of these, the Von Hipplel Lindau gene is the most commonly mutated gene in children presenting with a phaeochromocytoma. Referral to Clinical Genetics is recommended for genetic counselling prior to gene testing and investigation of the wider family. This review provides guidance on the aetiology, ...

We have presented a case of pheochromocytoma in a patient with the V804M mutation. To our knowledge, this is only the third case in the literature. It may be prudent to screen patients with this mutation for pheochromocytoma. Current endocrine society guidelines suggest that in low risk mutations screening may be started at an older age and done less frequently with biochemical testing. However, patients may have an indolent period where the biochemical markers may initially be normal. Hence, if a patient with this mutation is known to have an adrenal mass, vigilant monitoring of the mass with imaging as well as biochemical markers may be necessary to ensure there is no progression requiring intervention.. 1.

he intracellular distribution of 125I-labeled nerve growth factor (NGF) in rat pheochromocytoma PC12 cells was studied by quantitative electron microscopic (EM) autoradiography and by subcellular fractionation. PC12 cells were grown as monolayer cultures in medium supplemented with serum in the presence of 125I-NGF. EM autoradiography showed that 125I-NGF was localized at the plasma membrane and cytoplasmic compartments but did not accumulate in the nuclear chromatin or in the nuclear membrane compartment of cells analyzed after 1 hr and 1, 2, and 8 d of incubation with 125I-NGF. 125I-NGF also was not detected in nuclear subcellular fractions prepared from cells grown in serum-supplemented medium either in suspension for 1 d or in monolayer cultures for 1 to 8 d. In contrast, and in confirmation of the results of Yankner and Shooter (Yankner, B. A., and E. M. Shooter (1979) Pro. Natl. Acad. Sci. U. S.
