Abstract
Laryngeal paraganglioma (LP) is an exceptionally rare neuroendocrine tumor, underscoring importance of accurate identification to preclude misdiagnoses. In this review, we presented two typical misdiagnosed LPs, and offered reviews of LP cases reported over the preceding decade and all documented misdiagnosed LP cases. Furthermore, we systematically investigated the underlying causes of misdiagnosis and elucidated key points for effective differentiation. A retrospective analysis of 28 LP cases revealed a predominant occurrence in middle-aged women, with an average history of 25.1 months. Through an analysis of all misdiagnosed cases (n = 37), supraglottic LPs were frequently misidentified as laryngeal carcinomas and vascular tumors, while subglottic LPs were often misdiagnosed as thyroid cancers. And the occurrence of misdiagnosis resulted in delayed and inappropriate treatments, contributing to the deterioration of LP patients (14 cases, 37.8%). In conclusion, this review endeavored to heighten awareness of LPs, with the ultimate goal of advancing diagnostic precision and enhancing patient outcomes.

Abstract
INTRODUCTION Paragangliomas are rare tumours arising from the paraganglia of the autonomic nervous system. CASE REPORT We present a case of a paraganglioma arising from the hypoglossal nerve and producing an unusual clinical picture at presentation. DISCUSSION We supply radiological evidence of a paraganglioma originating from the hypoglossal nerve, and thus extend the evidence base for this rare site of origin. Our patient presented as an emergency with long tract neurological symptoms and progressive brainstem involvement. This presentation is not characteristic of paragangliomas in general, which usually have an indolent growth pattern and often demonstrate benign symptoms for a number of years prior to diagnosis. The location of a hypoglossal paraganglioma differs significantly from more common paragangliomas described in the neck and skull base, and this should inform the surgical approach undertaken.

Abstract
While 85-90% of laryngeal malignancies prove to be squamous carcinomas, the second most common tumour type found in the laryngeal region will prove to be a member of the family of neuroendocrine tumours. Laryngeal carcinoid tumours have a capacity for metastasis, and so are more aggressive tumours than their light microscopic features might imply--5-year survival rates are in the vicinity of 50%. Laryngeal atypical carcinoid tumours are lesions with a well-recognized capacity for local recurrence as well as metastasis, with a 5-year survival of just under 50%. Laryngeal small cell neuroendocrine carcinomas are particularly aggressive tumours, with a 5-year survival of no more than 5-10%. Laryngeal paragangliomas are lesions without any real capacity for metastasizing. Surgical excision is the mainstay of treatment of carcinoid tumours, atypical carcinoid tumours, and paragangliomas. Small cell neuroendocrine carcinomas are chiefly treated by way of radiation and chemotherapy; the role of adjuvant therapy in the treatment of atypical carcinoid tumours remains to be established.

Abstract
OBJECTIVES To review the clinical and pathological picture of laryngeal paragangliomas and compare laryngeal paragangliomas with the three other types of laryngeal neuroendocrine neoplasms. STUDY DESIGN The study presents a case review of a patient with a subglottic laryngeal paraganglioma treated at our institution, with a literature review of the laryngeal neuroendocrine neoplasms. Included is a review of all four neuroendocrine neoplasms, taking a close look at a comparison between laryngeal paragangliomas and atypical carcinoids tumors. All cases of subglottic laryngeal paragangliomas reported in the literature were also compiled and tabulated. METHODS The patient's record was reviewed for age, symptomatology, workup, and surgical procedures performed. RESULTS The patient was disease free 36 months after undergoing a tracheostomy for airway control, followed by a cricoid split for complete excision of the tumor. CONCLUSIONS It is important to differentiate among the four laryngeal neuroendocrine neoplasms, especially between atypical carcinoids and paragangliomas. Each tumor requires different treatments, with the former requiring a more aggressive approach. Paragangliomas must be completely excised to prevent their recurrence, and this approach should be considered a curative treatment. In addition, the immunohistochemical battery is of paramount importance in obtaining the correct pathological diagnosis.

Abstract
BACKGROUND Laryngeal paragangliomas are very rare neoplasms derived from the superior or inferior laryngeal paraganglia. The paragangliomas of the inferior laryngeal paraganglion, depending on their anatomic variability, can give rise to two different clinical expressions of the same process, namely the so-called thyroid paragangliomas and the inferior laryngeal or subglottic paragangliomas. METHODS We present a case for which we have not found any previous descriptions of a cervical and subglottictracheal relapse of a thyroid paraganglioma removed 3 years earlier. We review the literature. RESULTS We have found a total of 22 paragangliomas of the inferior laryngeal paraganglia, 23 including our case. CONCLUSIONS Thyroid paragangliomas and inferior laryngeal or subglottic paragangliomas should be included under the term "paragangliomas" of the inferior laryngeal paraganglion. These tumors are slow growing, benign, hypervascular, and much more common in middle-aged women. Immunohistochemistry is essential for its diagnosis. Open, conservative surgery is the treatment of choice.

Abstract
A paraganglioma is a neuroendocrine neoplasm that originates from the paraganglion cells of the parasympathetic system. The average age of presentation is in the fifth decade. We report a case of laryngeal paraganglioma in a five-year-old child, the youngest case ever recorded. The features of paraganglioma which differentiate it from other tumours are also discussed.

Abstract
Neuroendocrine neoplasms of the larynx have been divided into those of epithelial or neural origin. The latter consist of paragangliomas while the epithelial origin group can be divided into the typical and atypical carcinoids and small cell neuroendocrine carcinomata, the latter consisting of the oat cell type, the intermediate cell type and the combined cell type. There are now over 500 cases of neuroendocrine neoplasms of the larynx in the literature. The diagnosis is primarily based on light microscopy, and, in some instances, it may be supported by special histochemical studies. It should be confirmed by immunocytochemical and/or ultrastructural investigation. The different biological behaviour of neuroendocrine neoplasms of the larynx makes a specific diagnosis of paramount importance, since treatment depends on diagnostic accuracy. Typical carcinoid is an extremely rare lesion. It is treated preferably by conservative surgery; elective neck dissection is not necessary because of the lack of lymph node metastases at diagnosis. Chemotherapy and/or radiotherapy have not been effective in the limited number of patients treated thus far. Prognosis is excellent with cure following surgery. Atypical carcinoid is the most frequent non-squamous carcinoma of the larynx. The mainstay of treatment is surgery. Elective neck dissection should be performed because of the high likelihood of cervical lymph node metastases. Primary radiation therapy with adjuvant chemotherapy is not indicated. The survival rate is 48 per cent at five years and 30 per cent at 10 years. Although the larynx is one of its most common extrapulmonary sites, small cell neuroendocrine carcinoma is still a rare tumour. Surgical results for this tumour have been disappointing and is reserved for cases of local relapse with no evidence of metastasis. Chemotherapy and radiotherapy currently appear to offer the least disabling and most effective forms of therapy. The two- and five-year survival rates are 16 per cent and five per cent, respectively. Paraneoplastic syndromes have occasionally been reported in association with carcinoid tumours (typical and atypical) and small cell neuroendocrine carcinoma. There have been also rare reports of an elevated neuropeptide serum level. Paraganglioma is the only laryngeal neuroendocrine neoplasm with a female preponderance (3:1). Confusion with atypical carcinoid has led to incorrect diagnosis and inappropriate classification schemes, erroneously suggesting that laryngeal paraganglioma has the potential for aggressive behaviour. Conservative surgery represents the treatment of choice; elective neck dissection is not necessary, and the prognosis is excellent.

Abstract
Laryngeal paraganglioma originates in the neural crest cells in the laryngeal paraganglia. Two distinct types may be cited on the basis of clinical features, but biopsy is essential for diagnosis. By light microscopy, the Zellballen pattern appears pathognomonic. The treatment consists of surgical excision. In this article, due to the rareness of the tumour, one case of laryngeal paraganglioma is presented. The general knowledge and the available literature are reviewed. The difficulties in the differential diagnosis are stressed and treatment principles are discussed.

Abstract
The case of an atypical carcinoid tumour of the larynx is described in a 65-year-old man. This rare tumour may present diagnostic difficulties, but the diagnosis should be considered in a patient presenting with symptoms of local or referred pain and an apparently small, non-ulcerating supraglottic tumour. Immunocytochemistry has an important role in establishing the diagnosis. A very unusual feature of this case was positive staining for S-100 protein by sustentacular cells. Atypical carcinoid tumours do not respond well to radiotherapy so the primary treatment should be surgical resection.

Abstract
This study details the clinicopathologic features of 62 cases of laryngeal paraganglioma (LP), including 54 acceptable cases identified in the literature (although clinical information is lacking on 7 of these) and 8 previously unpublished cases identified from the Registry of Otolaryngic-Endocrine Pathology at the Armed Forces Institute of Pathology. Demographic findings show that the overwhelming majority of cases affect women (41:14), mainly in the fourth to sixth decades of life (age range, 14 to 83 years; median, 44 years), with a prevalence in the supraglottic larynx. These neoplasms are treated by surgical resection and are benign. Despite the characteristic pathologic features associated with LP, it is sometimes confused with other neoplasms, particularly neuroendocrine carcinomas of the larynx, and this confusion leads to unfortunate designations such as malignant paraganglioma and metastasizing paraganglioma of the larynx. Judging from the cases reported in this study and those identified in the literature, we conclude that malignant biologic behavior associated with LP is extraordinarily rare (< 2%). Because of the misdiagnoses of LP, the prognosis associated with this entity has been skewed to suggest that LP may behave aggressively. This has led to the inappropriate classification of LP among the malignant categories of laryngeal neuroendocrine neoplasms. The goal of this study is to detail the features diagnostic of LP and to discuss the appropriate treatment, prognosis, and classification of these neoplasms.
