“…Pelvic paraganglioma may present primarily to the gynecologist and may be treated initially as preeclampsia or other pelvic tumors [4][5][6]. The patient might present with vague pelvic symptoms and may not be forthcoming with the classical symptoms [5], and the unsuspecting gynecologist might miss these important clues leading to a potentially dangerous unplanned exploration.…”

“…The patient might present with vague pelvic symptoms and may not be forthcoming with the classical symptoms [5], and the unsuspecting gynecologist might miss these important clues leading to a potentially dangerous unplanned exploration. Suboptimal Imaging may reveal the mass to be related to the uterus and adnexa, and careful thin-section imaging with 3D reconstruction might reveal the exact anatomy of the mass.…”

“…To the best of our knowledge, only three cases of asymptomatic extra-adrenal retroperitoneal paraganglioma, showing precise clinical and radiologic findings, were previously reported in the English-language literature [2][3][4]. Imaging characteristics and preoperative diagnosis are summarized in Table 1.…”

“…The lack of clinical symptoms related to the excessive secretion of catecholamines obscures the diagnosis. Only a few cases of asymptomatic extra-adrenal paraganglioma have been reported in the English-language literature [2][3][4], and such cases are not fully understood. We report herein a rare case of asymptomatic extra-adrenal paraganglioma with malignant potential and review the literature.…”

A 41-year-old man without clinical symptoms was referred for treatment of an enlarging retroperitoneal tumor. Enhanced computed tomography showed a well-defined and heterogeneously enhanced tumor, 4 cm in size, in the dorsal portion of the pancreas. A low-density nodule was detected in the left adrenal gland, 10 mm in diameter. Retroperitoneal sarcoma and nonfunctional left adrenal tumor were suspected, and surgical treatment was performed. During excision of the retroperitoneal tumor, blood pressure was extremely elevated when the tumor was compressed. Blood pressure normalized after excision of the tumor; thus, a diagnosis of paraganglioma was favored over that of retroperitoneal sarcoma. The left adrenal gland was resected together with the adrenal tumor. Microscopically, the tumor cells of the retroperitoneum had round to oval nuclei, and abundant granular amphophilic cytoplasm proliferated in nest-like fashion. Extra-adrenal retroperitoneal paraganglioma was considered, and the adrenal tumor was diagnosed as cortical adenoma. In patients with retroperitoneal tumor, even in the absence of clinical symptoms, we should keep in mind the possibility of extra-adrenal paraganglioma.

“…The prevalence is higher in males and the average age upon diagnosis is 30 years [1]. Rarely, paragangliomas are located in other unusual sites, such as the gallbladder, mesentery, kidney, prostate, ovary and the esophagus [4,[7][8][9][10][11][12].…”

Malignant abdominal paraganglioma with lymph node metastasis: report of a case

View full text Add to dashboard Cite

Zusammenfassung. Grundlagen: Paragangliome sind seltene Tumore und treten meistens entlang der abdominellen Aorta bis zur Aortenbifurkation auf. Die Diagnose wird oft zufällig bei der radiologischen Abklärung wegen Bauchschmerzes gestellt. Gut-und bösartige Tumore haben ein identisches klinisches, radiologisches und histologisches Erscheinen, nur das Auftreten von lokaler Invasion oder Fernmetastasen bestätigt die Malignität.Methodik: Wir berichten über einen 49-jährigen Patienten mit einem 6,5 cm in der größten Ausdehnung über der Bauchaorta liegenden Tumor, welcher mittels CT diagnostiziert wurde. Eine Resektion des Tumors mit aortocavaler Lymphadenektomie wurde durchgeführt.Ergebnisse: Die histopathologische Aufarbeitung des Operationspräparates ergab ein malignes Paragangliom mit Lymphknotenmetastasen. Der operative und postoperative Verlauf war komplikationslos.Schlussfolgerungen: Maligne abdominelle Paragangliome sind seltene Tumore und aufgrund des mit der gutartigen Form identischen klinischen, radiologischen und histologischen Auftretens bestätigt nur die Präsenz von lokaler Invasion oder von Fernmetastasen die Malignität. Die Therapie der Wahl ist die komplette chirurgische Resektion. Nur ein multidisziplinäres Vorgehen erlaubt eine optimale Behandlung dieser ausgewählten Patienten.Schlüsselwörter: Bösartig, abdominelles Paragangliom, Lymphknoten, Metastasen.Summary. Background: Paragangliomas are rare tumors that generally occur in the abdominal paraaortic area down to the aortic bifurcation. Diagnosis is often made incidentally during radiologic work-up for abdominal pain. As benign and malignant lesions have identical clinical, radiologic and histologic features, the malignant potential is determined by local invasion and distant metastases.Methods: We report a 49-year-old male who underwent lymphadenectomy for a retroperitoneal tumor with a largest dimension of 6.5 cm above the abdominal aorta, which was diagnosed by CT.Results: Histopathologic resection of the specimen showed malignant paraganglioma with lymph node metastasis. The operative and postoperative course was uneventful.Conclusions: Malignant abdominal paragangliomas are rare tumors whose clinical, radiologic and histologic presentations are identical to the benign form; only the presence of local invasion or distant metastases confirms malignancy. The treatment of choice is complete surgical resection. Only a multidisciplinary approach will allow optimal treatment for this selected group of patients.
