Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach...

PURPOSE: Due to the rarity and the variety of histological types of sinonasal cancers, there is a paucity of data regarding strategy for their optimal treatment. Generally, outcomes of advanced and higher grade tumors remain unsatisfactory, despite the employment of sophisticated surgical approaches, technical advances in radiation techniques and the use of heavy ion particles. In this context, we critically evaluated the role of systemic therapy as part of a multidisciplinary approach to locally advanced disease...

Primary sinonasal tumors with neuroendocrine differentiation (STNDs) are uncommon, with overlapping histology. According to the amount of neuroendocrine component, they can be subcategorized into esthesioneuroblastoma, high-grade sinonasal neuroendocrine carcinoma/small cell carcinoma, and sinonasal undifferentiated carcinoma. Achaete-scute homolog 1 (ASH1) is a master gene for neuroendocrine differentiation and is expressed in fetal and adult neuroendocrine tissues. Expression of ASH1 protein may be a useful marker for cancers with neuroendocrine features...

Carcinoid tumors are neuroendocrine tumors that are most commonly found in the gastrointestinal tracts and lungs. They seldom develop in the head and neck area as a primary tumor, and there have been rare reports of them arising in the sinonasal area. We report a case of a 47-year-old woman with a typical carcinoid tumor arising in the sphenoid sinus.

Small cell neuroendocrine carcinoma of the paranasal sinuses is an extremely rare and aggressive neoplasm. Despite aggressive management, the tumor carries a poor prognosis, with a high risk of local recurrence or distant metastases. The management strategy is based on that for pulmonary small cell cancer and includes platinum-based chemotherapy combined with radiotherapy. We are reporting a case of an 89-year-old female patient diagnosed with small cell carcinoma of right-sided ethmoid and sphenoid sinuses...

Poorly differentiated sinonasal carcinomas are a heterogenous group of aggressive neoplasms that encompasses squamous cell carcinoma including basaloid variant, lymphoepithelial carcinoma, sinonasal undifferentiated carcinoma, and neuroendocrine-type small cell carcinoma. We herein describe 3 cases of a hitherto unreported variant combining features of basaloid carcinoma with variable intermingled rhabdoid cells. Patients were 2 women (aged 28 and 35) and a man (52 y) who presented with sinonasal masses. All had advanced local disease with bone involvement (pT4)...

Sinonasal neuroendocrine carcinomas (NECs) are rare tumors. We present a rare case of intracranial invasion of sinonasal small-cell NEC. A 61-year-old woman with nasal obstruction and bleeding was referred to our hospital. Computed tomography showed a polyp-like tumor occupying her left nasal cavity and extending to the paranasal sinuses and anterior cranial fossa. The tumor was removed using a transfacial approach by otolaryngologists and a bifrontal cranial approach by neurosurgeons. In histopathological analyses, we found that the tumor presented with both an epithelial and neuroendocrine nature, and was diagnosed as a small-cell NEC...

Small cell neuroendocrine carcinoma (SNEC) is an uncommon tumor. This tumor usually occurs in the lungs, the extra-pulmonary form accounts for only about 4% of all cases. Primary SNEC of the paranasal sinuses is extremely rare; only about 76 cases have been reported in literature. Unfortunately due to the rarity of this neoplasm, there are no specific recommendations pertaining to the management, treatment options are generally extrapolated from similar tumors of pulmonary origin. While Surgery was used in the past, upfront chemoradiation now seems to be evolving as the treatment of choice...

Sinonasal malignant neoplasms comprise only 3% of all head and neck malignancies. Synchronous and metachronous tumors of the head and neck have been described, but rarely have there been reports of a single tumor with two distinct histologies. Here, we describe a case of a sinonasal malignant neoplasm with two distinct histologies. A case report and literature review was performed. We present a case of paranasal sinus neoplasm involving two malignant cell types. An 83-year-old woman presented with a 2-year history of symptoms suggestive of chronic sinusitis, which included nasal congestion and intermittent midface pressure...

Sinonasal carcinoma with neuroendocrine differentiation (SCND) is a rare group of tumors known for their aggressive behavior and poor response to treatment. The data in the literature are sparse and cover a wide range of therapeutic approaches over a protracted timeline. Therefore, it is important that institutions report on their experience with these rare neoplasms. Clinical data, such as age at diagnosis, gender, tumor subtype and stage, treatment intention and modality, recurrence, salvage treatment, and survival of patients with a SCND, diagnosed at our department between 1980 and 2010, were retrospectively analyzed...
