We present a case of unusual cardiac paraganglioma (PG) initially misdiagnosed as atypical carcinoid tumor of the lung and discuss key clinical and pathologic characteristics that guide surgical management of these rare chromaffin cell tumors. A 64-year-old female with persistent cough and back pain was found to have a 4 cm × 3 cm mass abutting multiple cardiopulmonary structures. A biopsy was performed at an outside institution and pathology reported "atypical neuroendocrine carcinoma, consistent with carcinoid"...

There has been no attempt to clarify the status of patients with carotid body tumor (CBT) in Japan. This multi-institutional survey analyzed patients with CBT throughout Japan by gathering information on these patients from institutions that performed head and neck surgeries. Information from a total of 150 patients from 25 institutions from the past 20 years was employed in the present survey. There were 87 females and 63 males, and their mean age was 48.0 years old. The most common chief complaint was a neck mass and the mean suffering period was 46...

BACKGROUND: Carotid body tumor (CBT) is a form of head and neck paragangliomas (HNPGLs) arising at the bifurcation of carotid arteries. Paragangliomas are commonly associated with germline and somatic mutations involving at least one of more than thirty causative genes. However, the specific functionality of a number of these genes involved in the formation of paragangliomas has not yet been fully investigated. METHODS: Exome library preparation was carried out using Nextera® Rapid Capture Exome Kit (Illumina, USA)...

A 7 yr old female pit bull terrier was presented for a cervical soft tissue swelling located in the left jugular region. No abnormalities were present at physical examination or in the laboratory workup. Computed tomography and MRI scans showed a well-defined, ovoid, single mass in the left dorsal cervical region connected to the common carotid artery, histologically consistent with carotid body paraganglioma. The mass was surgically resected. Frameless stereotactic body radiation therapy with volumetric modulated arc therapy was set up as adjuvant treatment...

Herein we report the management of a giant, high-grade and vascular carotid body tumor in a young woman. She presented with slowly progressive neck swelling. Vascular imaging revealed a left-sided, high-grade giant carotid body tumor (> 8cm).  The tumor was completely excised by caudocranial subadventitial dissection. Histology of the tumor revealed a characteristic Zellballen pattern of the lesion, suggestive of a paraganglioma. The patient made an uneventful recovery. We also discuss newer insights regarding the management of such highly vascular lesions...

BACKGROUND: Schwannomas are benign, slow-growing neoplasms of the myelin-producing Schwann cells of peripheral nervous system that most commonly affect sensory nerves. Hypoglossal schwannomas, tumors of purely motor nerves, comprise <5% of all head and neck schwannomas. Since the first description of a hypoglossal schwannoma in 1933, there have been few case reports of extracranial origins. The most common location of an extracranial hypoglossal schwannoma is in the parapharyngeal space and can mimic paragangliomas...

Paragangliomas can be diagnosed accurately using magnetic resonance imaging and dynamic four-dimensional magnetic resonance angiography. Four-dimensional imaging uses the highly vascularised structure of these tumours, which results in a homogenous capillary blush and usually, due to the arteriovenous shunting, in an early draining vein. By these features the tumour can be differentiated from other neoplasms. The authors describe a case of a paraganglioma localised in the middle ear of an elderly patient. Magnetic resonance contraindications led to preoperative diagnostics with high resolution computed tomography of the temporal bone and additionally computed tomography perfusion imaging instead of magnetic resonance imaging with four-dimensional magnetic resonance angiography...

Objective  Treatment for head and neck paragangliomas (HNGPL) can be more harmful than the disease. After diagnosis, an initial period of surveillance is often indicated, and surgery or radiotherapy is reserved for progressive disease. With the aim to optimize this "wait and scan" strategy, we studied growth and possible predictors. Design  A retrospective cohort study was conducted. Setting  This study was conducted at a tertiary referral center for patients with HNGPL. Methods  Tumor volume was estimated for 184 SDHD -related carotid and vagal body paragangliomas using sequential magnetic resonance imaging...

A 58-year-old woman with a past medical history of a carotid body tumor, resected 4 months prior to presentation, was admitted to our hospital for treatment of a cardiac tumor that was identified on post-operative echocardiography and chest computed tomography. The cardiac tumor was surgically removed and identified pathologically as a paraganglioma, similarly to the carotid body tumor. Genetic analysis of both tumors identified a non-synonymous mutation in the succinate dehydrogenase (SDH) gene D, Exon4, c...

A 54-year-old woman was referred to thyroid evaluation because of a lump on the left side of the neck. Ultrasound exam did not show any thyroid abnormality, but highly perfused nodule at the left common carotid artery bifurcation was found. Because of the specific location, somatostatin receptor scintigraphy with Tc EDDA HYNIC-TOC was performed, starting with perfusion images and followed with SPECT/CT imaging at 2 and 4 hours. Well-perfused nodule with intensive accumulation and no other visible pathology in the body raised suspicion of a glomus tumor, consistent with MR exam performed later...

Ectopic thyroid tissue (ETT) lateral to the midline is rare. Its occurrence in the carotid bifurcation is exceptional. We present a 45 years woman who consulted with a slow growing right cervical swelling. Clinical examination Ultrasonography, contrast enhanced CT and cervical MRI concluded to a paraganglioma. Intra-operatively, the tumor didn't have the characteristic aspect of a paraganglioma. Complete excision was performed. Histology concluded to an ectopic micro-vesicular thyroid adenoma.Previous literature was reviewed to summarize clinical and radiologic characteristics of such rare entity...

BACKGROUND: Neuroendocrine tumors of the neck are rare swellings, which constitute about 0.03% of all tumors. Most are sporadically arising paragangliomas. Over 50% arise from the carotid bodies and pose difficulties in diagnosis and surgical management, which may result in disabling complications. OBJECTIVE: To determine the diagnostic, surgical, and postoperative challenges, and how to overcome them, in the management of neuroendocrine tumors of the neck. STUDY DESIGN: Descriptive case series...
