Abstract
Primary mixed neuroendocrine-nonneuroendocrine neoplasm (MiNEN) of the head and neck region is a rare biphasic tumor with an aggressive biological behavior. This report highlights an additional case of oropharyngeal MiNEN in a 46-year-old male patient with a previous long-term smoking history. Histologic evaluation revealed a biphasic tumor infiltrating the lamina propria. The first component consisted of a classic keratinizing squamous cell carcinoma. The second component consisted of small-to-intermediate sized cells with neuroendocrine features. Synaptophysin and CD56 immunohistochemical stains confirmed neuroendocrine lineage in this component. The presence of two morphological components with neuroendocrine and nonneuroendocrine features on histologic assessment should alert the pathologist to consider a MiNEN in their case work-up.

Abstract
Combined small-cell carcinoma and squamous cell carcinoma of the larynx is an exquisitely rare and underreported primary tumor the head and neck region, with an English literature review revealing only 17 documented cases. There is limited information on how best to treat these patients oncologically, given the low number of reported cases. A subset of the reported cases also detail a unique local spread of this combined carcinoma, further obscuring the clinical picture of these patients. Here, we detail an 18th case, with nodal metastasis of only one component of the primary tumor, and discuss the published literature surrounding this etiology.

Abstract
BACKGROUND There are many disputes about the definition, diagnosis, therapy, and prognosis of collision tumors.
CASE SUMMARY We describe a rare patient with a collision tumor consisting of neuroendocrine carcinoma (NEC) and squamous cell carcinoma (SCC) in the nasal cavity and paranasal sinus. She received operation, concurrent chemoradiotherapy, and then two cycles of palliative chemotherapy. Follow-up at 12 mo after diagnosis showed that this patient experienced a complete response with no signs of recurrence or metastasis. A literature review of previous 26 cases diagnosed with collision tumor of NEC and SCC in the head and neck was also undertaken.
CONCLUSION It is challenging to manage collision tumors because there are two morphologically and etiologically distinct tumors. Well-designed multimodality therapy including surgery and chemoradiotherapy might lead to a long survival in these patients.

Abstract
Here we report a 60 year aged male presented with complaints of right neck swelling of 3 months duration, swelling was initially small in size and gradually increasing. On examination right level II, hard mobile lymph node was palpable measuring 4 × 4 cm in size, oral cavity and oropharynx was normal. Computed tomography of face neck showed moderately enhancing soft tissue mass of 2 × 3 cm in the supra glottis and left level II cervical lymphadenopathy of size 5 × 5 cm with infiltrating into left sternomastoid muscle. Direct laryngoscopy revealed an ulcero proliferative growth in the supra glottis extending into vallaculla biopsy from the growth showed small round cells with scant amount of cytoplasm with hyperchromatic nucleus, atypical mitosis and at places rosettoid arrangement was seen. Immunohistochemistry with pancytokeratin, CD 56 and synaptophysin were positive, LCA was negative and Ki 67 was >70 %, features consisted with neuroendocrine carcinoma small cell type. Computed tomography of chest, abdomen and pelvis was normal. Finally it was labeled as localized neuro endocrine carcinoma small cell type of larynx (supraglottis). This patient treated with external beam radiotherapy 70 Gy in 35 fractions @ 2 Gy per fraction over 7 weeks along with concurrent chemotherapy with weekly cisplatin followed by adjuvant chemotherapy with Cisplatin and Etoposide for six cycles.

Abstract
The wide application of immunohistochemistry to the study of tumors has led to the recognition that epithelial neoplasms composed of both a neuroendocrine and nonneuroendocrine component are not as rare as traditionally believed. It has been recommended that mixed neuroendocrine-nonneuroendocrine epithelial neoplasms are classified as only those in which either component represents at least 30 % of the lesion but this cutoff has not been universally accepted. Moreover, since their pathogenetic and clinical features are still unclear, mixed neuroendocrine-nonneuroendocrine epithelial neoplasms are not included as a separate clinicopathological entity in most WHO classifications, although they have been observed in virtually all organs. In the WHO classification of digestive tumors, mixed neuroendocrine-nonneuroendocrine neoplasm is considered a specific type and is defined as mixed adenoneuroendocrine carcinoma, a definition that has not been accepted for other organs. In fact, this term does not adequately convey the morphological and biological heterogeneity of digestive mixed neoplasms and has created some misunderstanding among both pathologists and clinicians. In the present study, we have reviewed the literature on mixed neuroendocrine-nonneuroendocrine epithelial neoplasms reported in the pituitary, thyroid, nasal cavity, larynx, lung, digestive system, urinary system, male and female genital organs, and skin to give the reader an overview of the most important clinicopathological features and morphological criteria for diagnosing each entity. We also propose to use the term "mixed neuroendocrine-nonneuroendocrine neoplasm (MiNEN)" to define and to unify the concept of this heterogeneous group of neoplasms, which show different characteristics mainly depending on the type of neuroendocrine and nonneuroendocrine components.

Abstract
Introduction Small cell carcinoma/neuroendocrine carcinoma (SCNEC) of the oropharynx is uncommon. Two cases of SCNEC in an 81-year-old woman and in a 54-year-old man are presented here. Case description We have documented two cases of SCNEC arising in the oropharynx with evidence of high-risk human papillomavirus (HPV) infection. Histologically, both cases were classified as poorly differentiated SCNEC with high nuclear-to-cytoplasmic ratios and nuclear molding. Observations using a transmission electron microscope revealed membrane-bound neuroendocrine granules in some tumor cells. Both tumors expressed high levels of p16, a surrogate marker for high-risk HPV infection. HPV infection was confirmed in both cases using HPV polymerase chain reaction analysis; HPV subtype 16 was identified in one case and HPV subtype 18 in the other. Discussion and Evaluation SCNEC of the oropharynx is a rare and novel HPV-associated disease with neuroendocrine granules and aggressive clinical behavior. Conclusions Herein, we present two cases of SCNEC, focusing on its histologic features and treatment modalities. More studies are required to elucidate the pathophysiology of HPV-associated SCNEC in different organ systems.

Abstract
We herein report a very rare case of combined small-cell carcinoma (SmCC) of the hypopharynx, with a squamous cell carcinoma (SqCC) element. A 74-year-old man presented with a 3-month history of throat pain and hoarseness. On hypopharyngoscopy, a tumor was identified in the right anterior wall of the piriform sinus and, following examination of a biopsy sample, the lesion was diagnosed as SqCC. Total laryngectomy with bilateral neck dissection was performed and the malignancy was diagnosed as combined SmCC. One month after surgery, concomitant chemoradiotherapy with cisplatin and etoposide was administered. Immunohistochemically, the SmCC element was positive for CD56 and Ki-67 (50.2%), whereas the SqCC element was positive for cytokeratin 34βE12 and Ki-67 (47.5%). Furthermore, the SmCC element was positive for KIT and platelet-derived growth factor α (PDGFRα), while the SqCC element was positive for epidermal growth factor receptor (EGFR) and PDGFRα. By genetic analysis, a silent mutation in the PDGFRα gene was recognized. The expression of KIT, PDGFRα and EGFR in this case provided evidence that combined SmCC may be a candidate for molecular-targeted therapy, although further investigations are required.

Abstract
A hamartoma is a benign malformation of native tissue that may occur in any area of the body. Hamartoma of the tongue is a rare developmental lesion. We describe the case of a pendulant lingual hamartoma in a 2-day-old girl that had not been identified on prenatal ultrasonography. We also review the utility of prenatal imaging options, the role of preoperative imaging, the mechanical relationship between lingual hamartoma and cleft palate, the histopathology of this tumor, surgical treatment, and emergency airway management.

Abstract
The primary laryngeal atypical carcinoid is relatively rare, and the tumor combined with other histologic types including squamous cell carcinoma is extremely rare. We experienced a case which was complicated with atypical carcinoid and squamous cell carcinoma. A 79 years old man complaining of sputum was admitted to Hiroshima City Hospital. A tumor was seen in over the right glottis and the right vocal fold was fixed. Squamous cell carcinoma was diagnosed based on a biopsy harvested under laryngoscopy. Imaging studies (CT, MRI) were done. The primary tumor was in the right aryepiglottic fold, and one swollen lymph node was found in level 2 (right side). Based on the findings, the stage was T3N1M0. We performed a total laryngectomy and right neck dissection. Atypical carcinoid and squamous cell carcinoma were detected in the same tumor. There were two lymph node metastases, both of which were atypical carcinoid metastases. Postoperative irradiation was provided. It is now 4 years since the operation, but the patient lives without relapse and metastasis of this disease.

NUT midline carcinomas in the thymic region. Mod Pathol 2014; 27:1649-56.

Abstract
NUT midline carcinomas (NMCs) are rare tumors described predominantly in the pediatric age group. We recently reported two cases of these tumors occurring in the thymic region. In order to establish the true incidence of these tumors, we examined a large series of thymic carcinomas for morphological features of NUT tumor and further assessed the expression of NUTM1 (also known as NUT) protein by immunohistochemistry. The histological review of slides from 110 cases of thymic carcinoma was undertaken to identify carcinomas with mixed undifferentiated and squamous features that are typically associated with NUT carcinomas. The presenting symptoms, morphological spectrum of tumors and outcome data of patients with these histologies are presented. Immunohistochemistry for NUTM1 was performed on 35 cases of thymic carcinoma with available blocks (3 with these histological features and 32 without these features) to exclude the possibility of midline carcinoma. Tumors from 10 patients had features of mixed small cell undifferentiated squamous cell carcinoma (M:F, 1.5:1; age range, 22-79). These patients predominantly presented with advanced disease and had respiratory-related symptoms or chest pain; four had paraneoplastic syndromes. The squamous component in all cases was well differentiated with little or no atypia. The undifferentiated component varied in cell size and lacked characteristic features of small cell carcinoma. All but one patients developed metastases or died within 3 years of diagnosis. NUTM1 expression was seen in two of three tumors with these histological features and in none of the 32 cases without. Mixed small cell undifferentiated carcinomas share histological and immunohistochemical similarity with NMCs and have aggressive clinical course. These tumors are not uncommon and should be considered in the differential diagnosis of carcinomas in the thymic region as novel therapies might be available.

Abstract
BACKGROUND Current recommendations on the treatment of neuroendocrine carcinoma of the larynx (NCL) are based on anecdotal evidence. With this meta-analysis, our purpose was to provide clinicians with more substantiated guidelines in order to improve the treatment outcome of the patients affected with NCL. METHODS A structured literature search for all research concerning NCL was performed against the MEDLINE and EMBASE databases. Available data was normalized, pooled, and statistically analyzed. RESULTS Four hundred thirty-six cases of NCL were extracted from 182 studies, of which 23 were typical carcinoid, 163 were atypical carcinoid, 183 were small-cell neuroendocrine carcinoma, 29 were large-cell neuroendocrine carcinoma, and 38 were unspecified carcinoid tumors. The 5-year disease-specific survival (DSS) was 100% for typical carcinoid, 53% for atypical carcinoid, 19% for small-cell neuroendocrine carcinoma, and 15% for large-cell neuroendocrine carcinoma (p < .001). Patients with an atypical carcinoid treated with surgery had better DSS than those treated with radiotherapy (60% vs 54%; p = .035). Postoperative radiotherapy did not result in better DSS in atypical carcinoid. Patients with an atypical carcinoid, not undergoing surgical treatment of the neck, developed isolated regional recurrence in 30% of cases (p = .001). Radiochemotherapy yielded the best DSS for small-cell neuroendocrine carcinoma compared to other modalities (31% vs 13%; p = .001). CONCLUSION Typical carcinoid can be treated by local excision alone. Atypical carcinoids do not seem to respond well to radiotherapy and are best managed through radical surgical excision in combination with elective neck dissection. Patients with small-cell neuroendocrine carcinoma or large-cell neuroendocrine carcinoma seem to benefit most from chemoradiotherapy.

Abstract
Small cell carcinoma (SmCC) most commonly occurs in the lung and rarely arises from the head and neck region. Further, composite SmCC is extremely rare. Therefore, no postoperative treatment strategy has been established. We report a 59-year-old male patient referred to our outpatient clinic for further examination and treatment of a laryngeal tumor. Biopsy from the tumor revealed squamous cell carcinoma (SCC). The preoperative diagnosis was supraglottic SCC (T3N2bM0), and total laryngectomy and bilateral neck dissection were performed. Pathological examination revealed 2 individual cancer components: SmCC and SCC. Postoperative chemoradiotherapy (2 courses of cisplatin (CDDP) and etoposide (VP-16)) was indicated. Following the postoperative chemoradiotherapy, 2 courses of adjuvant chemotherapy were administered. The patient is currently alive with no evidence of disease at 36 months following the completion of therapy. Postoperative chemoradiotherapy and adjuvant chemotherapy are optimal treatment strategies for laryngeal composite SmCC.

Abstract
A case of combined small cell and squamous cell carcinoma of the larynx in a male patient in the sixth decade of life is reported. The etiopathogenesis of this combined tumor remains unclear; however, a number of hypotheses were proposed in the past including the pivotal role of Kulchitsky, squamous cells and the glandular cells. The gene mutations may also play an important role in laryngeal carcinogenesis. This unusual type of laryngeal combined carcinoma has previously been reported worldwide in only 17 cases. This is an extremely rare tumor the histological nature of which makes the diagnosis more complicated than in other types of laryngeal cancers. The diagnosis of this carcinoma is based on light microscopy and should be supported by immunohistochemical studies. In our case, the tumor was growing in the left pyriform sinus. Metastatic neck lymph nodes were found on the left side, but no distant metastases were observed. Microscopic sections revealed a combined tumor composed of small cell carcinoma neuroendocrine type and non-keratinizing squamous cell carcinoma. Positive reaction to p16, bcl-2, thyroid transcription factor 1, synaptophysin and chromogranin A in the small cell neuroendocrine type carcinoma component was observed. The cells from squamous cell carcinoma component showed positive reaction to p63, high-molecular-weight cytokeratin and cytokeratin 5/6.

Abstract
We report an extremely rare case of combined small cell carcinoma (combined SmCC) of the hypopharynx. A 73-year-old male presented with multiple left neck swellings for 1 month. A tumorous lesion was found in the left pyriform sinus, and biopsy revealed that the lesion was squamous cell carcinoma (SqCC). Surgery was performed and pathological examination led to a diagnosis as combined SmCC, composed of SqCC and small cell carcinoma (SmCC). One month after surgery, a contrast-CT indicated metastases to the cervical lymph node (LN), mediastinum and liver. We performed 5 courses of chemotherapy with the use of cisplatin (CDDP) and irinotecan (CPT-11). The patient temporarily showed a favorable response to the chemotherapy; however, eventually he died of regrowth of the tumor. Combined SmCC is a disease with a poor prognosis. Although biopsy sometimes fails to detect the SmCC component, intensive diagnosis and treatment are necessary.

Abstract
Neuroendocrine neoplasms of the larynx are rare but are the most common nonsquamous tumors of this organ. In the past, there has been considerable confusion about the nature and classification of these neoplasms, but the current consensus is that there are 4 different types of laryngeal neuroendocrine tumors composed of paraganglioma, typical carcinoid, atypical carcinoid tumor, and small cell neuroendocrine carcinoma. Carcinoids and small cell neuroendocrine carcinomas are epithelial neoplasms, whereas paragangliomas are of neural origin. Diagnosis is based primarily on light microscopy and confirmed by immunohistochemistry and electron microscopy. Precise diagnosis is essential because the natural history, treatment, and prognosis vary widely for the different neoplastic categories. Typical carcinoids are very rare and are treated by wide local excision, usually partial laryngectomy, without elective neck dissection. Atypical carcinoid tumors are more common and more aggressive. They are treated by partial or total laryngectomy with elective or therapeutic neck dissection. Adjuvant chemo/radiotherapy may be of benefit in some cases. Small cell neuroendocrine carcinomas are highly aggressive and should be considered disseminated at initial diagnosis. The treatment is by irradiation and chemotherapy as surgery has proven to be of a little benefit. Paragangliomas are treated by local excision or partial laryngectomy. It is difficult to determine the valid survival statistics for typical carcinoids because of their rarity and confusion in the literature with their atypical counterparts. They have a greater tendency to metastasize, and thus a worse prognosis than was previously believed. Atypical carcinoid tumors have a 5-year survival rate of approximately 50%, which decreases with time. The prognosis of small cell neuroendocrine carcinoma of the larynx is dismal, with 5-year survival rates of 5%. The biological behavior of laryngeal paraganglioma is generally benign and the prognosis is excellent.

Abstract
OBJECTIVE We report the first case of a laryngeal composite tumour consisting of a squamous cell carcinoma combined with an atypical carcinoid. METHODS Case report and review of the literature concerning laryngeal composite tumours. RESULTS Primary laryngeal carcinoma is the most common malignancy of the upper aerodigestive tract. The vast majority are of the squamous cell type. Primary neuroendocrine neoplasms represent a rare, heterogeneous subset of laryngeal malignancies, comprising typical carcinoid, atypical carcinoid, small cell carcinoma and paraganglioma. Primary combined neuroendocrine and squamous cell carcinoma of the larynx is even more rarely encountered, with only 14 publications of this so-called composite tumour to date. In each case, the neuroendocrine component has been small cell carcinoma. CONCLUSION The treatment of primary neoplasms comprising more than one histological type is tailored to the most biologically aggressive tumour. Accurate diagnosis of the histological nature of laryngeal composite tumours is imperative to ensure optimal therapy.
