All the patients were symptomatic with hypertension being the most frequent symptoms (100%). Pheochromocytomas in 72 They are slender, with thin wisps of cytoplasm encompassing the chief cells (16). Malignant adrenal pheochromocytoma. This publication was reviewed by Hartmut and colleagues who assessed the patient’s relatives and demonstrated that the original patient and her family had multiple endocrine neoplasia type 2 by providing molecular evidence (5). Vascular invasion wasn’t identified. The majority of tumors showed areas of degenerative changes, including cyst formation, hemorrhage and fibrosis. In our study, one patient presenting syndromic presentation had unilateral tumor, in the other hand, another one presented bilateral tumours without other special findings, but an additional genetic study seems to be compulsory in order to rule it out. Tunis; Campus Universitaire, Tunis El-Manar, 2092 Tunis, Tunisia. This fact may be secondary to the few number of cases and the low surface area under the ROC curve. Additionally, each university/college has ratings based on student reviews and are ranked below accordingly. patients. Some authors reported that tumors with SDHB mutations are associated with shorter survival (24). Minerva Endocrinol 2009;34:107-21. 3-2 Microscopic findings In general, the pheochromocytomas associated with syndromes behave in a benign fashion (21, 22). Melicow MM. Malignant tumors are defined as tumors with metastases at referral or follow up. Modlin IM, farndon JR, Shepherd A, et al. Diagnosis, localization, and Tumor cell spindling wasn’t noted.

Disseminated intravascular coagulation (DIC) is a life-threatening event during resuscitation. RESULTS malignant pheochromocytomas. malignant pheochromocytoma. Mitotic figures were inconspicuous or absent in all cases. A PASS score was performed in all cases identifying presumably benign tumors with a PASS score less than 4 and malignant ones with a PASS score equal or superior to 4. Features that were present in both benign and malignant tumors were given a lower weight, whereas those identified more frequently in malignant tumors were given a heavier weight. Two patients had what was considered to be a non sporadic tumor: an association with a syndrome known to include an increase incidence of adrenal pheochromocytoma. It was diagnosed in our study in one patient with benign pheochromocytoma.

Materials were supplemented by a review of the patient demographics (gender, age), symptoms and physical findings at presentation (diaphoresis, headaches, palpitations, weakness, syncope or dizziness, anxiety, flushing, chest pain, nausea, hypertension including paroxysmal type, vomiting and weight loss), including duration, medical and surgical history. The mean age at presentation was 26 years. Poll H. Die vergleichende Entwicklung der nebennierensysteme.

The area under the ROC curve was estimated to 0,417. Bilateral disease is generally associated to syndromic presentation. Table 4 shows the different PASS scores. The tumors were of low to medium cellularity with 3 tumors showing high cellularity. Prognostic value of Pheochromocytoma of the adrenal gland scaled score Many prognostic factors have been studied in the literature without a real consensus.

The second population is the sustenticular cell which is thought to be a supporting cell similar to the glial cells in the central nervous system. N Engl J Med 2002;346:1459. No focal spindle cell architecture was found. Tumor cell monotony was identified in 3 cases. Thompson LDR. Laboratory values, specifically related to catecholamines (serum or urine) and their various metabolites, were obtained in all cases. The second patient presented hepatic metastases after 33 years of follow up. One tumor was described as bilateral and occurred in a patient with syndromic association (neurofibromatosis).

We have supported clinical trials using the full range of GI imaging modalities, from video endoscopy to MRI and intestinal ultrasound. Comparison of adrenal and extra adrenal pheochromocytomas. Facing the difficulty in diagnosing MPH, their challenging management and the absence of consensus concerning the prognostic factors, a PASS score was developed by taking the patients whose tumors were clinically and histologically malignant and identifying the histologic features that were uniquely present or present in a greater frequency than in the patients whose tumors were clinically and histologically benign. Thompson LDR, Young WF, Kawashima A, Komminoth P, Tischler AS. In malignant tumors, the PASS score was >=4 in both cases. Two patients presented a malignant pheochromocytoma and the other patients presented benign tumors. Nebennierentumor und gleichzeitiger Nephritis mit Veranderungen am J Surg Res 2009;3:1-8.
