Abstract
PURPOSE OF REVIEW Although non-squamous tumors of the larynx are really rare, they may not always be viewed from the same perspective in the multidisciplinary treatment approach once the diagnosis is made. In this review, non-squamous tumors of the larynx and current approaches in treatment will be discussed. RECENT FINDINGS When the studies and meta-analyses presented in the last 5 years are evaluated, it is seen that these tumors usually show non-specific symptoms. Due to their submucosal location, the stage of the disease at the time of diagnosis is often advanced. In the literature, treatment may vary in these particular cases. The majority of non-squamous tumors of the larynx includes minor salivary gland tumors, neuroendocrine carcinomas, sarcomas, cartilage tumors, and malignant melanomas. Once treating a patient with these diagnoses, it should be kept in mind that the histopathological subtype is almost as important as the stage of the tumor.

Abstract
Background Small cell oesophageal carcinoma (SCEC), a rare neuroendocrine malignancy, presents various challenges in diagnosis and treatment. The condition is characterised by rapid dissemination, a marked responsiveness to chemotherapy, and a guarded prognosis. While the European Neuroendocrine Tumour Society has recommended platinum-based chemotherapy, ongoing debates on optimal strategies and the lack of clear guidelines underscore the need for further comprehensive research efforts. Methods This study retrospectively analysed 12 cases of localised pure SCEC treated at a UK tertiary care centre between 2006 and 2020. We systematically analysed and categorised the cases based on stage, performance status, and patient age. This comprehensive approach enabled a nuanced examination of overall survival (OS), thereby providing valuable insights into the differences between outcomes. Results The study revealed a median OS of 12.01 months for treated non-metastatic cases, highlighting the challenges of SCEC management. Conversely, treated metastatic cases exhibited a mean survival of 9.15 months, which contrasts starkly with the 2.55 months demonstrated by those receiving best supportive care (BSC). These figures underscore the urgency for refined strategies in handling advanced localised disease and the need to continue research endeavours to devise methods to enhance the precision and optimise outcomes beyond the presented data. Conclusion Based on our findings, the combination of chemoradiotherapy and surgery to manage SCEC holds promise; however, further research is needed to optimise the management approach. The lack of clear guidelines underscores the imperative for personalised treatment approaches.

Abstract
Small cell carcinomas (SCCs) are poorly differentiated neuroendocrine tumors that arise predominantly in the lung and gastrointestinal tract (GIT). Neuroendocrine carcinomas can occur in a variety of extrapulmonary sites throughout the body, including breast, larynx, GIT, prostate, urinary bladder, ovary and cervix. This is a case report of a 55-year-old Asian female patient with metastatic high-grade neuroendocrine carcinoma of unknown origin that responded notably to off-label nivolumab maintenance treatment after first-line carboplatin - etoposide chemotherapy and radiation. After 2 years of nivolumab after platinum-based chemotherapy results from PET-CT showed no residual disease and we proceeded to mastectomy.

Abstract
Small-cell breast carcinoma (SCBC) is a very rare type of aggressive breast cancer constituting less than 1% of all breast cancers. The WHO classification categorizes this tumor as small-cell neuroendocrine carcinoma, and its prognosis is usually worse as compared to invasive breast cancers. We report a 64-year-old Caucasian female who presented with a large fungating left breast mass. Biopsy of the mass revealed small-cell carcinoma of the breast, negative for all 3 receptors (estrogen, progesterone, and Her2/neu). Imaging studies were negative for distant metastasis. She was subsequently treated after multidisciplinary discussion utilizing neoadjuvant chemotherapy with platinum agents and etoposide, modified radical mastectomy with axillary lymph node dissection, and adjuvant radiation therapy. Since she has triple-negative small-cell breast cancer, she will be followed with active surveillance without hormonal therapy. With less than 100 cases reported and in the absence of evidence-based standard treatment guidelines, we have reviewed various case series reported in the literature. We further discuss various chemotherapy regimens used previously, adverse prognostic factors of breast neuroendocrine tumors, common receptor status, and genetic mutations found in SCBC.

Abstract
Cervical lymph node SmCC as a primary tumor’s location, was never described in the literature according to what we know. AC neuroendocrine carcinoma of the tonsil has never been described in the literature up to our knowledge. A review of the literature was performed, indicating treatment and disease’s prognosis. In 2012, the 2005 WHO classification of neuroendocrine tumors of the head and neck region was modified by adding the ranges of the Ki-67 and suggested that LCNEC should be considered a distinct disease entity and be separated from AC.
Introduction Primary neuroendocrine carcinomas are uncommon head and neck malignancies. Their classification is still debated. We report four cases of unusual primary locations of neuroendocrine carcinomas of head and neck region emphasizing two entities and rare sites that were never described in the literature to the best of our knowledge. Presentation of cases We reported four different cases of neuroendocrine carcinomas (nasal cavity, larynx, lymph nodes and tonsil) treated in our institution. The diagnosis was made by biopsy and confirmed by Immunohistochemical study. We underscored 2 atypical and rare entities in their location and anatomo histopathological type. Chemotherapy and radiotherapy were proposed for patients with nasal’s and laryngeal locations. This latter had also undergone surgery. For lymph node location, the patient received decompressive radiotherapy alone. The patient diagnosed with neuroendocrine carcinoma of the tonsil didn’t get any treatment except initial tonsillectomy for diagnosis purposes. Regarding the evolution in our case series, 2 patients had a relapse with local and regional metastasis. Among the 4 patients, 50 % passed away, one is still alive with deterioration of his general status and one is lost to follow-up and refused undergoing further investigations. Discussion There is confusion in the literature regarding the classification of neuroendocrine carcinomas. According to the 2005 WHO, these lesions, can be subdivided into TC, AC (including LCNEC), SmCC, combined SmCC with nonsmall cell carcinoma, and paraganglioma. Their treatment is still debated. Through an overview of the literature, we have gathered the main studies and 2 meta-analysis summarizing the mainstay treatment and disease’s outcome. Conclusion Neuroendocrine carcinomas of head and neck region are aggressive tumors with poor prognosis, low incidence and their diagnosis is not obvious. The treatment protocol depends on the type, the site of the lesions, and metastasis status. It’s still not well codified.

Abstract
Sinonasal small cell neuroendocrine carcinoma is a rare tumour in the head and neck region. Patients become symptomatic as the disease progresses to advanced stages. They are at risk for recurrence and distant metastasis following treatment. Early diagnosis and treatment have shown to improve the disease prognosis. This is a retrospective analysis of sinonasal small cell neuroendocrine carcinomas that underwent treatment based on institutional protocol. Data was collected from medical records of the patients and analyzed using descriptive statistics. Cell morphology on electron microscopy and immunohistochemistry played a significant role in differentiating small cell neuroendocrine carcinoma from other neuroendocrine tumours. 75% of cases presented in an advanced stage of malignancy. None of the patients had distant metastasis at initial presentation. Equal proportion of cases underwent surgery followed by adjuvant radiation (33.3%) and concurrent chemoradiation (33.3%). 25% of patients had recurrence of disease. The 2-year overall survival rate was 78.8%. Disease-free survival for cases that underwent surgery followed by radiation was higher than that of chemoradiation or radiation alone arms. There has been an improvement in treatment outcomes of sinonasal small cell neuroendocrine carcinoma which is best explained by paradigm shift in multimodality management towards surgery followed by adjuvant treatment.

Abstract
Small cell carcinoma of the gall bladder is a rare tumor. The neoplasm is highly lethal, metastasizes early, and may cause death shortly after diagnosis. An oat cell carcinoma of the gallbladder metastatic to the liver and adjacent lymph nodes is described in a 60-year-old male. Partial cholecystectomy was performed followed by aggressive chemotherapy with etoposide and cisplatinum. An 80 % reduction in the size of the unexcised tumor was noted over a period of 6 months. The partial response and the relatively long survival of the patient suggest the use of the above protocol for these rare cases.

Abstract
Undifferentiated small cell carcinoma of the bladder is a rare but aggressive subset of urinary tract neoplasms. Analogous to small-cell carcinoma of the lung, this tumor frequently exhibits neuroendocrine differentiation. We report the 92nd and 93rd case of small cell carcinoma of the bladder reported in the literature with characteristic cytologic, histologic, histochemical, and ultrastructural features. The patients were treated initially with chemotherapy, but after a brief clinical course died for progression of disease and for myocardial infarction, respectively. The pathologic and clinical features and therapeutic options of the cases described in the literature are reviewed.

Abstract
Aims and Background Small cell carcinoma of the bladder (SCCB) is a rare entity characterized clinically by an aggressive behavior with a high incidence of systemic metastases. We report the clinicopathologic findings of five cases. Methods We reviewed five consecutive patients with SCCB treated at our institute. In each case the following clinical data were recorded: age, sex, presenting symptoms, endoscopically determined location of the tumor, clinical staging, node involvement (if any), site of metastases (if any), treatment, follow-up and outcome. Results There were four male and one female patients, age range 42 to 68 years, mean 57.6 years. The clinical presentation was not different from conventional transitional cell carcinoma, with hematuria being the most frequent complaint (four cases). Microscopic examination revealed oat cells in three cases and an intermediate variant in one. At the time of diagnosis the tumors were staged as T3bN2M0, T2N2M0, T4N0M0, T3aN0M0, and T2N0M0. Primary therapy consisted of radical cystectomy alone (one case), transurethral resection (TUR) alone (one case), TUR with chemotherapy (two cases), or TUR with chemotherapy and radiotherapy (one case). Four patients died of progressive disease, with survival from the time of diagnosis ranging from 7 to 16 months (mean, 12.2 months). One patient died of myocardial infarction (unrelated to the primary disease) one month after diagnosis. Conclusion Our study indicates that primary small cell carcinoma of the urinary bladder is as aggressive as its pulmonary counterpart and the overall prognosis of this tumor is very poor.

Abstract
Aims and Background Extrapulmonary small cell carcinoma is a distinct entity that can occur in many sites, and it is pathologically similar to small-cell lung cancer. We report the results of a retrospective study of a multimodality treatment of 16 consecutive patients with a diagnosis of extrapulmonary small-cell carcinoma. Methods Primary tumor site was prostate in 2, gallbladder in 2, uterine cervix in 2, liver in 2, endometrium in 1, epididymis in 1, colon in 1, larynx in 1, breast in 1, and unknown primary tumor in 3 patients. Patients’ ages ranged from 19 to 79 years (median, 62). Nine patients had limited and 7 had extensive disease. Histologically, 14 were pure extrapulmonary small-cell carcinoma and 2 were mixed with squamous-cell carcinoma. Results Curative surgery was attempted in 8 patients. Seven patients received local-regional adjuvant radiotherapy. All patients, except the one with a breast primary, were treated with chemotherapy (mostly platinum-based regimens). Overall survival for all patients was 41% and 11% at 2 and 5 years, respectively (median survival, 14 months). Median survival for patients with limited disease was 25 months compared to 12 months for patients with extensive disease (P = 0.05). Conclusions Treatment results for extrapulmonary small-cell carcinoma are comparable to those of small-cell carcinomas of the lung. Extent of disease is a significant prognostic factor for survival.

Abstract
A case of oat-cell carcinoma arising in the pericardium of a 51-year-old woman is described. The patient had multiple nodes; the largest was 2 × 1 cm. Two years later the patient presented with a tumor on her lower gum; this measured 2 mm and had similar characteristics to the previous one. The immunohistochemical study showed strong positivity for neuron-specific enolase. From review of the literature, it may be concluded that this is the first report of oat-cell carcinoma occurring in the pericardium.

Abstract
The authors describe a case of small cell carcinoma of the esophagus that was treated by concurrent chemoradiotherapy. Both the esophageal tumor and the regional lymph node metastases disappeared after this treatment. The patient is alive and disease free after more than five years. Primary small cell carcinoma of the esophagus is a rare and aggressive neoplasm with a very poor prognosis, and the treatment modality is controversial. This case illustrates the possibility of treating this tumor type with concurrent chemoradiotherapy.

Abstract
Neuroendocrine carcinomas are rare tumors. In the head and neck region they are most common in the larynx, where they represent 0.5-1% of epithelial cancers. Diagnosis requires the recognition of the typical neuroendocrine architecture and morphology and the immunohistochemical confirmation of neuroendocrine differentiation. In the 1991 WHO classification laryngeal neuroendocrine carcinomas have been divided into carcinoids, atypical carcinoids, small cell carcinomas and paragangliomas. Atypical carcinoids in the head and neck region usually show an aggressive behavior analogous to poorly differentiated carcinomas, and are resistant to chemo- and radiotherapy. For this reason, it was recently proposed to change their designation to “moderately differentiated neuroendocrine carcinomas”. We present the clinical and histopathological features of 2 moderately differentiated neuroendocrine carcinomas of the larynx, one large cell poorly differentiated neuroendocrine carcinoma of the oropharynx, and one small cell carcinoma of the minor salivary glands of the tongue. The patient with small cell carcinoma was free from disease 26 months after radical surgery, while the other patients showed liver, lung and bone metastases 18, 26 and 24 months after the diagnosis despite radical surgery or concomitant intra-arterial chemotherapy and radiotherapy.

Abstract
Primary small cell carcinoma (SCC) of the esophagus is characterized by high malignancy with a tendency to metastasize early through lymph and blood circulation. Metastasis of esophageal SCC frequently occurs to distant organs such as liver and lung. However, few cases of appendiceal metastasis have been reported. This paper first presents a pathologically confirmed case with metastasis of esophageal SCC to the appendix. This particular case highlights the importance of pathological diagnosis and provides new evidence of appendiceal metastasis from esophageal SCC.

Abstract
The most common primary tumors of the frontal sinus are osteomas and inverted papillomas, although a variety of other tumors involving this space have been reported. With the advent of new surgical techniques and instrumentation, an endoscopic approach to this region has become feasible. The preoperative assessment and decision making must take into account the complexity of frontal sinus anatomy, tumor type, tumor location, and associated attachments. These procedures allow adequate visualization, tumor removal, and postoperative monitoring, and preserve fairly normal sinus function. Open techniques may also be required and should be in the surgeon's armamentarium.

Abstract
Small-cell undifferentiated carcinoma (SCUC) has been increasingly recognized in the urinary tract. 1,2,3 Up to 66% of SCUCs in this location are associated with a minor component of a more differentiated carcinoma that most frequently represents transi tional-cell carcinoma (TCC), but adenocarcinoma, squamous-cell carcinoma, spindle- cell carcinoma, and carcinoid carcinoma have all been described. We report a case of low-grade TCC of the urinary tract metastasizing to a distant location and therein dedifferentiating into an SCUC and discuss the clinical and biologic implication of the process of dedifferentiation. Int J Surg Pathol 2(2):157-162, 1994

Abstract
This article reports the clinical, histopathologic, and immunohistochemical findings in a case of small cell undifferentiated carcinoma of the submandibular gland. The tumor was composed of anaplastic cells slightly larger than lymphocytes without ductal differentiation. On immunohistochemical analysis, the tumor contained cells that reacted positively with antibodies to cytokeratin, neuron-specific enolase, synaptophysin, and chromogranin. The present case supports the hypothesis that small cell undifferentiated carcinomas of the salivary glands arise from presumed multipotential ductal stem cells. When this tumor entity is located on the salivary glands, it appears to behave less aggressively than when it is a primary tumor of the bronchial tree.

Abstract
Small cell carcinoma (SCC) is most commonly associated with lung cancer. Extra-pulmonary SCC can originate in virtually any organ system, with the gastrointestinal tract being the most common site of involvement. We review the clinical presentation, pathogenesis, histology, imaging modalities and optimal therapeutic management of PSCC in light of available evidence.

Abstract
Small cell carcinomas of the urinary bladder originating from the neuroendocrine cells are extremely rare. We present a case of a 76–year–old patient with small cell carcinoma of the urinary bladder. The patient had hematuria and cystoscopy revealed a tumor located in a urinary bladder diverticulum. Partial resection of the bladder wall with diverticulectomy was performed. Microscopic examination established the diagnosis of neuroendocrine carcinoma, which was confirmed by immunohistochemistry. Three–month follow–up showed no recurrent disease. Patient refused further chemotherapy and radiotherapy.

Abstract
Combined small cell carcinoma (SmCC) and squamous cell carcinoma (SqCC) is a rare malignant neoplasm in the head and neck. This study presents the first reported case of combined SmCC and SqCC originating from the sinonasal tract accompanied by syndrome of inappropriate secretion of antidiuretic hormone (SIADH). An 80-year-old female presented with a four-week history of right nasal discharge, nasal obstruction and left neck swelling. Imaging studies revealed a tumorous lesion in the maxillary sinus encroaching upon the right nasal cavity and left cervical lymph node (LN) swelling. An incisional biopsy carried out from the right maxillary sinus and LNs resulted in a diagnosis of combined SmCC with SqCC, staged as T4aN2cM0. Clinical examination revealed a sustained increase of antidiuretic hormone, hyponatremia with urinary sodium increase, and serum hypo-osmosis, resulting in SIADH. Water restriction to <1,000 ml/day was effective in improving sodium and osmotic imbalance. Curative treatment for the tumor was not prescribed due to the poor condition of the patient. Palliative treatment was administered and the patient succumbed to cachexia five months after histological diagnosis. The presence of SIADH may have marked implications for the treatment and prognosis of this disease.

Abstract
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. We report a case of sinonasal SNEC who had undergone definitive concurrent chemoradiation and is currently disease-free for close to 2 years. The clinical presentation, imaging studies, histopathological diagnosis with immunohistochemistry correlation, management protocols, and a brief review of literature of this rare tumor is discussed.

Abstract
Primary gastric small cell carcinoma is a rare and aggressive malignant disease with a poor prognosis that was first reported in 1976 by Matsusaka et al. The incidence is very low and the clinicopathological features are similar to those of small cell lung carcinoma. We herein report a case of successful treatment by combination chemotherapy consisting of irinotecan hydrochloride and cisplatin for primary gastric small cell carcinoma. The patient was a 71-year-old male who was admitted to a local hospital with anemia. Gastrointestinal endoscopy revealed the presence of advanced gastric carcinoma at the upper region of the stomach. The patient underwent surgery, and the pathological diagnosis was small cell carcinoma due to the presence of the typical features of small round cells with scant cytoplasm that were positive for synaptophysin and chromogranin A in the resected specimen. The patient underwent subsequent combination chemotherapy, which provided him with over 1 year of survival and a good quality of life. We also present a review of the literature regarding chemotherapy for primary gastric small cell carcinoma.

Abstract
Background Extrapulmonary small cell carcinomas have been reported in a variety of organs, and their incidence in the genitourinary tract is second only to that in the gastrointestinal tract. To date, however, only a few cases of small cell carcinoma of the ureter have been reported. Because the extreme rarity of this type of carcinoma, its clinical behaviour, diagnostic methods, and effective treatment modalities have not yet been determined. Case presentation A 59-year-old man presented with a 1-month history of painless gross haematuria. Urine cytopathology revealed a urothelial carcinoma and computed tomography revealed left hydronephroureterosis with a distal ureteral stone and a mildly enhanced fungating mass just below the stone-impacted site. The preoperative TNM stage was T2N0M0. The patient underwent simultaneous diagnostic ureterorenoscopy and left laparoscopic nephroureterectomy with bladder cuff resection. Gross examination showed a 3.5 × 3.0 × 0.8 cm white, partly yellow mass in the left distal ureter. Light microscopy showed a small cell carcinoma, overlaid on a urothelial carcinoma in situ, invading the ureter and external lateral resection margins. The small cell carcinoma was diffusely positive for neuron-specific enolase, and exhibited focal positivity for CD 56, synaptophysin, chromogranin and cytokeratin 20. The patient was treated with adjuvant chemotherapy, consisting of cisplatin and etoposide, and radiation therapy, and has been well, without evidence of tumour recurrence or metastasis in the 10 months after surgery. Conclusion Small cell carcinoma of the ureter is rare. Although its clinical behaviour and diagnostic modalities have not been determined and it has yet to be diagnosed immunohistopathologically, multimodality treatment including surgery, chemotherapy and radiotherapy may improve patient survival.

Abstract
Salivary gland small cell carcinoma is a rare neoplasm, accounting for less than 1% of salivary gland tumours. Little is known about the epidemiologic factors and treatment of this lesion. The authors report two cases and perform a systematic literature search from 1960 to 2011 for articles on salivary gland small cell carcinoma. Once the papers were reviewed, a database was generated to analyse clinical and pathological features, treatments and outcomes, and an attempt was made to identify prognostic factors. Available data were retrieved for 44 cases which fully satisfied the inclusion criteria; the median age was 64.25 years and the male:female ratio was 2.4:1. The parotid gland was the most common site (79.6%). The overall 1-, 2- and 5-year survival rates were 75.3%, 56.4% and 36.6%, respectively. According to the present review, patient age, tumour size, distant metastasis and cytokeratin-20 positive immunostaining were all significant prognostic factors in a univariate analysis. No particular treatment approach appeared to improve survival. This work reinforces knowledge about salivary gland small cell carcinoma's epidemiologic features, and identifies new prognostic markers. The optimal management of this lesion remains controversial.

Abstract
Primary neuroendocrine carcinoma of breast (NECB) is a very rare tumor; the World Health Organization(WHO) subcategorized these tumors into 3 major histologic subtypes: solid, small cell carcinoma (SMCC), and large cell NE carcinoma. The SMCC subtype is the least common and most aggressive and has been reported to be as aggressive as its pulmonary counterpart. SMCC is usually confirmed based on clinical, pathologic,and imaging studies. Local disease is usually managed in a fashion similar to that of the usual ductal breast cancer; in the metastatic SMCC setting, regimens that are implemented in small cell lung cancer are usually attempted, according to case reports and published small case series. Hormone receptors can be expressed in more than 90% of the solid tumor subtype; however its expression is manifested in about 50% of cases of SMCC. Although hormonal therapy can be used successfully to treat the usual metastatic ductal breast cancer,its utility in metastatic SMCC has not been reported. We report an impressive response to hormonal therapy in a patient with late relapse of breast carcinoma with a metastatic SMCC subtype that expressed hormone receptors. The response to hormonal therapy was sustained for about 12 months. The response to hormonal therapy is definitely an interesting finding that, to our knowledge, has not been described before in the setting of metastatic SMCC. We suggest considering adding hormonal therapy to the treatment pipeline for primary SMCC of the breast that express hormone receptors.

Abstract
Background Non-sinonasal neuroendocrine carcinomas (NSNECs) of the head and neck are considered an unfrequent clinico-pathological entity. Combined modality treatment represents an established therapeutic option for undifferentiated forms where distant metastasis is a common pattern of failure. Methods We report on a case of NSNEC treated with sequential chemo-radiation consisting of 6 cycles of cisplatin and etoposide followed by loco-regional radiation to the head and neck and simultaneous prophylactic cranial irradiation to prevent from intracranial spread, delivered with helical tomotherapy with the 'hippocampal avoidance' technique in order to reduce neuro-cognitive late effects. Results One year after the end of the whole combined modality approach, the patient achieved complete remission, with no treatment-related sub-acute and late effects. Conclusions The present report highlights the importance of multidisciplinary management for NSNECs of the head and neck, as the possibility to achieve substantial cure rates with mild side effects with modern radiotherapy techniques.

Abstract
Primary small cell neuroendocrine carcinoma of the paranasal sinuses is an extremely rare and distinctive tumor with aggressive clinical behavior. We report on a patient who had a small cell neuroendocrine carcinoma of the ethmoid sinus with invasion of the upper aspect of the right maxillary sinus and medial aspect of the right orbit. After 2 cycles of chemotherapy that were unsuccessful, he underwent radiotherapy with complete tumor remission. Local recurrence was not identified after 11 months of follow-up; however, distant metastasis developed 2 months after radiotherapy. The natural history, pathologic features, and choice of therapy for this rare neoplasm are discussed, along with a review of the published data.

Abstract
Back ground Primary small cell carcinoma of the pancreas (SCCP) is a rare malignancy with an extremely poor prognosis which accounts for 1 to 1.4 percent of all pancreatic malignancies. Case presentation We present the case of a 62-year-old man with a half-month history of upper abdominal discomfort who was diagnosed with SCC of the pancreatic tail. A Chest X-ray showed no evidence of primary lung tumor. The diagnosis of a SCCP was confirmed by post-surgery pathology and immunohistology. In our review of the published reports of SCCP, we only found a few cases reported in the literatures. The diagnosis of SCCP needs the post-surgery pathology and immunohistology and the prognosis of SCCP is extremely poor. There was a significant increase in median survival, from 1 to 6 months, in treated patients compared to patients treated only by symptomatic management. Chemotherapy was the most common treatment and the combination of cisplatin/etoposide was most frequently prescribed. Conclusion The accurate diagnosis of (SCCP) is necessary for determining prognosis and deciding appropriate therapy.

Abstract
Management of malignant neoplasms of the sinonasal tract and skull base is hampered by the relative low incidence and pathologic diversity of patient presentations. Many studies have reported successful outcomes in the endoscopic management of malignancy since 1996, and these are summarized in this article. Nonsurgical adjuvant therapies are important for locoregional control because surgery occurs in a restricted anatomic space with close margins to critical structures, and distant disease is an ongoing concern in these disorders. There remains a need for collaborative consistent multicenter reporting, and international registries have been established to assist in such efforts.

Abstract
Small cell carcinoma of the esophagus (SCCE) is a rare and aggressive malignant tumor with a poor prognosis. The aims of this retrospective study were to analyze the epidemiology, clinical characteristics, and treatment outcomes of these patients. Between 1994 and 2004, 24 patients with SCCE from several centers were reviewed for data on demographics, presenting symptoms, diagnosis, disease stage, type of treatment, and outcome. SCCE occurs in the sixth decade: median age (interquartile range [IQR]): 65 (59-69) years with a male predominance (63%). The most common complaining symptoms were rapidly progressive dysphagia (79%), weight loss (54%), and retrosternal/epigastric pain (46%). The tumor arises primarily in the middle (52%) or in the lower (35%) third of the esophagus. History of tobacco and alcohol exposure was present in 90% and 70% of case, respectively. Extensive disease was present in 13 cases (54%) at initial diagnosis. The overall median survival (IQR) was 11 (8-20) months for all 24 patients, and the 2-year overall survival was 25.1%. Four patients were alive more than 2 years after treatment. Chemotherapy increased the survival compared with symptomatic management in extensive disease (median survival [IQR]: 9.5 [6-14] vs. 6 [4-7] months, P= 0.05). In limited disease, concurrent chemo-radiotherapy was more effective than non-concurrent treatment (median survival [IQR]: 36 [14-93] vs. 11 [9-15] months, P= 0.04). Two patients were treated by surgery and chemoradiation therapy with a survival of 35 and 66 months. Chemotherapy is the cornerstone of treatment of SCCE in all stage. For limited disease SCCE, concurrent chemo-radiotherapy is the primary choice compared with sequential approach. The role of surgery was not assessable in our study.

Unusual case of small cell gastric carcinoma: case report and literature review. Dig Dis Sci 2011; 56:951-7.

Abstract
BACKGROUND Small cell carcinomas are among the most aggressive, poorly differentiated, and highly malignant of the neuroendocrine tumors (NETs). Of which, small cell gastric carcinoma is a rare small cell neuroendocrine tumor. The purpose of our study was to present this case and perform a comprehensive literature review. METHODS AND RESULTS We review a case of small cell gastric carcinoma that is particularly unusual in that it occurred in a woman from the US when the majority of cases of small cell gastric carcinoma have been reported in men from East Asia, and more specifically, from Japan. The diagnosis was made after endoscopy revealed a large ulcerated mass in the gastric cardia of Borrmann type 3. Biopsies revealed multiple small basophilic cells underlying the squamous epithelium of the esophagus and cardiac mucosa, indicating the presence of a tumor at the gastroesophageal junction. Immunostaining established the diagnosis with positive stains for chromogranin, synaptophysin, and CD56. Our patient is being treated with chemotherapy, but many different treatment regimens have been tried for small cell gastric carcinoma with variable success. CONCLUSIONS Overall prognosis for small cell gastric carcinoma is dismal. Neuroendocrine tumors in general have variable clinical behaviors and prognosis is dependent on the neuroendocrine tumor type. The adoption of a standardized classification system for neuroendocrine tumors could improve the recognition of infrequently encountered neuroendocrine tumors like small cell gastric carcinoma and will enhance strategies for treatment and thus improve prognosis for patients with these rare and aggressive tumors.

Abstract
Introduction Neuroendocrine bladder cancer is extremely rare, with an estimated incidence of 0.35–0.70% of all bladder tumors. The small-cell carcinoma represents the most frequent histologic variant described. Small-cell carcinoma is an epithelial tumor associated with a more aggressive behavior and poorer prognosis than transitional cell bladder carcinoma. The overall survival rate at 5 years does not exceed 8%. At the time of presentation 59% of patients have clinical stage >T2 and 56% show metastatic disease. In 50% of the patients, fatal progression occurrs within 6 months. Local recurrence after radical surgery occurred in 50–70% of cases. Patients and Methods We report three cases of pure neuroendocrine small-cell bladder cancer. Hematuria was the most common presenting symptom. Local advanced disease was present in all the cases with stage >T2, metastatic disease in 1 case, lymph node involvement and ureteral bilateral obstruction in 2. Two patients were treated by radical cystectomy, bilateral pelvic limph node resections and urinary derivation. Platinum-based adjuvant chemotherapy was proposed but only two patients received the treatment. One patient with liver metastasis was managed only by extensive TUR and support regimen. Results In 2 patients residual or relapsed cancer reappered within 2 months after surgery. All of the three patients died of metastatic disease at 5, 7, and 13 months. Median overall survival was 7 months. The most common site of relapse and spread of disease was the peritoneum and intestinal tract, and the reason of death was uncontrolled acute hemorrhage from gastro-intestinal district. Conclusions In the absence of a prospective study, and because of the rarity of the disease, the best treatment for small-cell bladder cancer remains uncertain. Neoadjuvant chemoterapy with platinum regimen plus aggressive surgical approach will be the treatment of choice. The association of chemotherapy and radiotherapy should also be considered.

Abstract
BACKGROUND The incidence of symptomatic brain metastases in small-cell carcinoma of the urinary bladder (SCBC) is unknown. This precludes advice about prophylactic cranial irradiation (PCI). PATIENTS AND METHODS The medical records of all patients with SCBC seen at The Netherlands Cancer Institute from 1993 to 2009 (n = 51) were reviewed. Limited disease (LD) was defined as any pT, cN₀₋₁, and cM₁. Patients with LD were offered bladder-preserving treatment involving combined chemoradiotherapy. Patients with extensive disease (ED) were treated with palliative chemotherapy. PCI was not applied in any patient. RESULTS Among 39 patients with LD, median disease-specific survival was 35 months. Four developed symptomatic brain metastases after a median follow-up of 15 months (range 3-24) and were treated with whole-brain radiotherapy. No patient with ED developed symptomatic brain metastases during a median follow-up of 6 months. The reported incidence of brain metastases in SCBC in the literature ranges between 0% and 40%. On the basis of all reported series, the pooled estimate of the cumulative incidence of brain metastases is 10.5% (95% confidence interval 7.5% to 14.1%). CONCLUSIONS The incidence of symptomatic brain metastases from SCBC is significantly lower than that from small-cell lung cancer. Therefore, we do not routinely advise PCI in patients with SCBC.

Abstract
Extrapulmonary small-cell carcinoma (EPSCC) is a clinicopathological entity distinct from small-cell carcinoma (SCC) of the lung. The aim of this study was to review the clinico-pathologic features, treatment modalities, and factors prognostic for survival in patients with EPSCC. We retrospectively reviewed the medical records of patients with EPSCC diagnosed between January 1995 and July 2004 at the Asan Medical Center. We identified 61 patients with EPSCC, 37 with limited disease (LD) and 24 with extensive disease (ED). The most common primary sites were the gastrointestinal (GI) tract (56%) and uterine cervix (18%). Overall survival (OS) at 1 and 3 years was 59% and 29%, respectively, with a median survival of 16 months (range, 1 approximately 56 months). Treatment information was available for 51 patients, 34 with LD and 17 with ED. Of the 34 LD patients, 25 underwent surgery. Surgery was the only treatment modality in five patients, two of whom remained alive and disease free at last follow-up, 27 and 47 months after surgery, respectively. Adjuvant chemoradiotherapy was administered to 11 patients, nine of whom (82%) had distant failure with a median overall survival of 23 months. Of the eight patients who received adjuvant chemotherapy, four (50%) had distant failure, with a median survival of 21.7 months. In univariate analysis, advanced disease status, as measured by VALSG (LD vs. ED) stage, was a significant prognostic factor for OS (p<0.001). Interestingly, there were no statistically significant differences in progression-free survival or OS between patients with pure (n=45) and mixed (n=16) EPSCC. Overall, the response to various treatment modalities and the median survival time observed were discouraging. Patients with GI primary tumors had poorer prognoses than those with primary tumors at other locations. Fifty six percent of patients with a GI primary tumor had ED at the time of diagnosis, whereas 100% of patients with SCC of the uterine cervix had LD at the time of diagnosis and showed a favorable clinical course. The majority of patients with LD SCC who underwent surgery, followed by adjuvant chemotherapy or chemoradiotherapy, showed tumor recurrence and/or systemic metastases. Clinical trials are needed to define adequate treatment strategies for EPSCC.

Abstract
Small cell carcinoma of the breast is a very rare entity that is histologically indistinguishable from small cell carcinomas of other organs. The presence of an in situ component is the most important feature that indicates the primary nature of the breast tumor. Thyroid transcription factor-1 (TTF-1) is a marker specific to lung and thyroid but is also expressed in small cell carcinoma of pulmonary and extrapulmonary origin. TTF-1 expression in breast small cell carcinoma has been reported only rarely. This reported case is unique because of the characteristic morphological features and immunohistochemical profile. The invasive tumor demonstrated neuroendocrine differentiation morphologically and immunohistochemically, expressed by TTF-1, EGFR, and basal-type cytokeratins. An unequivocal in situ component was identified intimately admixed with the invasive carcinoma. To the authors’ knowledge, this is the first report of breast small cell carcinoma showing the expression of “basal markers.”

Abstract
Primary small cell neuroendocrine carcinoma (SNEC) of nose and paranasal sinuses is an extremely rare malignant tumour known for its aggressive clinical course, high rate of recurrence and poor prognosis. Only 69 cases have been reported in world literature till March, 2006. This tumour usually occurs in elderly persons with main complaints being nasal obstruction, epistaxis, loss of visual acuity, exophthalmos, local pain and rarely tender swelling over the sinuses. Computerized tomography scan (CT) is essential to assess the size, extent of the tumour, evidence of bone destruction and infiltration to orbit and brain. Due to its rarity, the understanding of pathogenesis of the disease, diagnosis and ideal treatment have been difficult. The origin of the tumour is believed from basal cells of the olfactory mucosa. The present study deals with three cases of SNECs of nose and paranasal sinuses in elderly males, their clinical presentations, CT scan findings, histopathological diagnosis with short review of literature.
