Abstract
Neuroendocrine tumors are rare and highly heterogeneous neoplasms with a wide spectrum of histological differentiation, functional, and biological features. Small cell neuroendocrine carcinomas (SNECs) of the sinonasal tract are particularly rare. Pathological features of SNECs of the nasal cavity and paranasal sinuses, which are aggressive tumors, are similar to those of anaplastic small cell carcinomas of the lung. We present a case of high-grade sinonasal SNECs in a patient with Xeroderma pigmentosum complementation group C (XPC) gene-positive xeroderma, which, to our knowledge, is the first case reported worldwide.

Abstract
Small cell neuroendocrine carcinoma of nasopharynx is extremely rare and displays aggressive nature with a poor prognosis. Neuroendocrine tumours rarely arise from the head and neck region and pose a diagnostic and management challenge. In English literature, only 16 cases of primary small cell neuroendocrine carcinoma of nasopharynx have been reported so far; and to the best of our knowledge, this is the seventeenth case and second in the younger age group. Here, we report the case of an adolescent male patient who presented with nasal blockage, repeated episodes of epistaxis and neck swellings. After proper diagnostic workup, the diagnosis of small cell neuroendocrine carcinoma of nasopharynx was made. The patient was treated with chemotherapy, followed by radiotherapy. Imaging investigation executed after the end of the treatment exhibited complete remission of the disease. The patient is kept under active surveillance with no signs of relapse at present.

Abstract
Neuroendocrine tumors are a spectrum of rare and highly heterogeneous neoplasms with distinct functional and biological behavior in relation to location, tumor size, and histological differentiation. Neuroendocrine tumors arise from the neuroendocrine cells of the diffuse neuroendocrine system located in almost every organ. Neuroendocrine tumors in the head and neck district are usually reported in sinonasal cavities and larynx. We present the case of a nasopharyngeal small-cell neuroendocrine carcinoma, which, as far as we know, is the 16th case reported in literature.

Abstract
Neuroendocrine carcinomas (NECs) are poorly differentiated neuroendocrine tumors of the upper respiratory tract. We present an extremely rare case of nasopharyngeal large cell neuroendocrine carcinoma (LCNEC) synchronized with nasopharyngeal squamous cell carcinoma (SCC). Both SCC and LCNEC are associated with Epstein-Barr virus (EBV) infection, supported by the positive result of Epstein-Barr encoding region in-situ hybridization. Strong correlation is found between EBV infection and nasopharyngeal malignancies. Furthermore, the EBV status might be a crucial prognostic factor in nasopharyngeal LCNEC. EBV-positive LCNEC is effective to chemoradiotherapy, and may have preferable outcome than EBV-negative LCNEC arising in the nasopharynx or other sites. The recognition of the EBV status is important for patients to receive appropriate treatment.

Abstract
Neuroblastoma (NB) is the most common extra-cranial cancer of early childhood and rarely occurs in adults. The clinical symptoms of NB can be diverse. We discuss a rare case of an adult NB presenting as acute leukemia. A 45-year-old woman presented with persistent hip pain, weight loss, anemia, and incidental fever for several months. Imaging studies showed diffuse bone marrow (BM) uptake and hypermetabolic lesions involving the left adrenal gland, bilateral axillary nodes, and left lateral aspect of the abdomen. Her 24-hour urine catecholamines were within the normal range. On the peripheral blood film, blast-like cells were noted, occupying approximately 2% of leukocytes. The BM imprints showed infiltration of blast-like cells with convoluted nuclei and scant cytoplasm in more than 85% of the total nucleated cells. Acute leukemia was initially suspected based on morphology. Blast-like cells were negative for myeloperoxidase, combined esterase, periodic acid-Schiff, CD45RB, CD68, and CD138. In a further study, these cells were positive for CD56, synaptophysin (SYN), and CD99 with negativity for desmin, myogenin, NKX-2.2, CD31, cytokeratin (AE1/AE3), Melan-A, ERG, S-100, and SALL4. Morphologically similar neoplastic cells in axillary node biopsy were positive for CD56, chromogranin A, SYN, and neurofilament, but negative for GFAP, CD246, and vimentin. Based on laboratory, pathological, and imaging studies, metastatic NB with BM and multifocal involvement was diagnosed. The differential diagnosis of metastatic small blue round cell tumors should be considered for adult patients with circulating blast-like cells, and an accurate diagnosis would enable the patient to receive appropriate and timely treatment.

Abstract
Background Nasopharyngeal small cell carcinoma (SmCC) is a rare histological type of nasopharyngeal cancer, and its prognosis remains poor. This study aimed to determine the clinical characteristics and survival prognostic factors of nasopharyngeal SmCC. Methods Detailed clinicopathologic and therapeutic characteristics of a patient diagnosed with nasopharyngeal SmCC were determined. Nasopharyngeal SmCC cases reported previously were reviewed and summarized. Furthermore, a retrospective analysis was performed on data from the Surveillance, Epidemiology, and End Results (SEER) Program database. Kaplan–Meier analysis was conducted to compare survival within groups. Univariate and multivariate analyses were performed to investigate prognostic factors. Results A nasopharyngeal SmCC patient treated with chemoradiotherapy who achieved 46 months long-term survival was reported. In reviewing 16 reported cases with epidemiologic and therapeutic details, we found most of nasopharyngeal SmCC patients were diagnosed with advanced grades and received chemoradiotherapy. In total, 13,993 cases of nasopharyngeal cancer were extracted from the SEER database, from which 57 nasopharyngeal SmCC cases were eventually screened out. The mean age of the patients was 55.70 years, and 64.9% of these cases were either grade III or IV; the median overall survival (OS) was 18 months. Statistically significant differences were observed in the OS values of groups categorized by age (P = .025) or radiotherapy (P = .037). Age (<70 years) and radiotherapy were identified as independent survival and prognostic factors. Conclusion Patients with nasopharyngeal SmCC are usually diagnosed with advanced grades and have poor prognoses; nevertheless, they can benefit from radiotherapy with prolonged overall survival.

Abstract
We present a 49-year-old woman with a history of an unresectable nasopharyngeal small cell carcinoma (SCC) who was treated with concurrent chemotherapy and radiation therapy. On surveillance positron emission tomography scan 14 months after diagnosis, her primary tumour appeared stable, but there was fludeoxyglucose uptake in the pancreas. A CT scan demonstrated a 3.4×2.1 cm ill-defined soft tissue mass at the tail of the pancreas, which was concerning for adenocarcinoma. However, further workup including endoscopic ultrasound and fine needle aspiration confirmed the mass to be a metastasis from her nasopharyngeal SCC. Because there have been no previously reported cases of a metastatic small cell carcinoma to the pancreas, there are no data about prognosis. Thus treatment options were tailored to the patient. Distal pancreatectomy, splenectomy and cholecystectomy were performed. The patient recovered from surgery without complication.

Abstract
Primary small cell neuroendocrine carcinoma is uncommon in head and neck region, with occasional cases in nasopharynx. Distinction from other round cell tumors is imperative to ensure optimal patient management. We present a case of a 30-year-old woman who presented with a rapidly growing nasopharyngeal mass.
