Abstract
An 84-year-old man presented with a localized, firm, tender mass over the right lacrimal sac. He had a history of acute dacryocystitis in the same eye 6 months before presentation, which resolved with antibiotics followed by uneventful dacryocystorhinostomy. At repeat presentation, the patient underwent orbital imaging and excisional biopsy of the lesion. Histologic studies revealed a small cell neuroendocrine carcinoma. The patient was subsequently treated with chemotherapy and radiation. Although there are rare reports of small cell neuroendocrine carcinoma originating in the sino-orbital-lacrimal region, this is the first report of tumor presentation with acute dacryocystitis in a patient with prior dacryocystorhinostomy.

Abstract
Extrapulmonary small cell carcinoma (EPSCC) is a rare and aggressive clinical entity that can involve a variety of anatomic locations, including the gastrointestinal tract. Involvement of the gastrointestinal tract is associated with a particularly poor prognosis with patients often presenting with widespread dissemination on initial clinical presentation or rapidly progressing to systemic disease from locoregional involvement. Primary small cell carcinoma of the anal canal is extremely rare, with limited published case reports in the literature. As a result, management of this disease is not well defined, and outcomes are poor with high rates of disease relapse. We report a patient with locally advanced anal small cell carcinoma after presenting with irregular bowel movements, changes in stool caliber, and rectal bleeding for two months and achieved a durable complete response to concurrent chemoradiation with cisplatin and etoposide followed by consolidation chemotherapy and discuss our current understanding of this disease. Specifically, we review the epidemiology, risk factors, clinical course, the treatment strategies over the past two decades, and prognosis for EPSCC. Finally, we conclude our discussion by reviewing the rationale of our treatment regimen and the potential role and benefit of consolidation therapy in the management of this rare and aggressive disease.

Abstract
BACKGROUND Extrapulmonary small cell carcinoma is a rare malignancy with scarce data. Treatment paradigms extrapolate from pulmonary small cell carcinoma and single institution studies. We analyzed the epidemiology, patterns of care, prognostic factors, and overall survival (OS) of EPSCC patients. METHODS The cohort included EPSCC. Patients with <2 months follow-up, unknown demographic/treatment variables were excluded. Descriptive statistics were performed to characterize the cohort. Kaplan-Meier methods were used to estimate OS. Cox proportional hazard modeling was done to analyze the influence of prognostic variables on OS. RESULTS 5747 patients were included. Median OS was 1.2 years. Head and neck (HR: 0.60, 95% CI 0.53-0.67, p < 0.0001) and breast (HR: 0.69, 95% CI 0.53-0.89, p = .0046) were associated with improved OS; gastrointestinal (HR: 1.19, 95% CI 1.09-1.29, p < .0001) worse OS; and gynecologic (HR: 1.04, 95% CI 0.92-1.17, p = .5660) showing no difference, all compared to genitourinary (reference). Surgery was associated with improved overall survival (HR: 0.84, 95% CI 0.79-0.91, p=<.0001). Chemoradiation showed a decreased HR (HR: 0.91, 95% CI 0.83-0.99, p = .0363) when compared to chemotherapy alone (reference). CONCLUSION EPSCC occurs throughout the body with poor survival. Anatomic subsite was predictive for survival. Surgical resection may improve survival. Concurrent chemoradiation appears to improve survival over chemotherapy alone.

Abstract
Small cell carcinoma (SCC) of the bladder is a rare malignancy, representing less than 1% of bladder cancers diagnosed annually in the USA. In contrast to SCC of the lung, paraneoplastic syndromes are rarely documented in cases of extrapulmonary SCCs, particularly those of genitourinary origin. We present a case of SCC of the bladder presenting with paraneoplastic syndrome of inappropriate antidiuretic hormone, which resolved after treatment with sequential chemoradiation.

Abstract
Extrapulmonary small cell carcinomas (EPSCC) are a rare subtype of neuroendocrine tumours which have been documented to arise from a multitude of sites and treatment outcomes are disappointing. The most common site involved in the head and neck region is the larynx and the oropharynx as a primary site has been infrequently reported. The patient presented with bilateral neck swelling and an ulcerated lesion was noted in the base of tongue (BOT). A biopsy revealed small cell carcinoma (SCC) and was confirmed with immunohistochemistry. The final diagnosis after workup was SCC of BOT stage IVc. He received induction chemotherapy to which the tumour responded partially, followed by curative intent chemoradiotherapy and adjuvant chemotherapy. The patient achieved a radiological complete response to treatment and almost all treatment-induced toxicities resolved. An aggressive approach to managing EPSCC is possible with modern radiotherapy techniques, with tolerable treatment-induced toxicities.

Abstract
OBJECTIVE Extrapulmonary small cell carcinoma (EPSCC) is rare and frequent metastases at presentation can complicate efforts to identify a site of origin. In particular, SCC comprises <1% of prostate cancers and has been implicated in castration resistance. METHODS Clinical, laboratory, imaging, and pathology data are presented. RESULTS A 56-year-old man with locally advanced prostate adenocarcinoma on androgen deprivation therapy presented with a clogged nephrostomy tube. Laboratory results included calcium 13.8 mg/dL (8.5-10.5 mg/dL), albumin 3.6 g/dL (3.5-5 mg/dL), and potassium 2.8 mmol/L (3.5-5.2 mmol/L). Hypercalcemia investigation revealed intact PTH 19 pg/mL (16-87 pg/mL), 25-OH vitamin D 15.7 ng/mL (>30 ng/mL), and PTH-related peptide (PTHrP) 63.4 pmol/L (<2.3 pmol/L). Workup for hypokalemia yielded aldosterone 5.3 ng/dL (<31 ng/dL), renin 0.6 ng/mL/h (0.5-4 ng/mL/h), and 6:00 a.m. cortisol 82 µg/dL (6.7-22.6 µg/dL) with ACTH 147 pg/mL (no ref. range). High-dose Dexamethasone suppression testing suggested ACTH-dependent ectopic hypercortisolism. Contrast-enhanced CT findings included masses in the liver and right renal pelvis, a heterogeneous enlarged mass in the region of the prostate invading the bladder, bilateral adrenal thickening, and lytic lesions in the pelvis and spine. Liver biopsy identified epithelioid malignancy with Ki proliferation index 98% and immunohistochemical staining positive for synaptophysin and neuron-specific enolase, compatible with high-grade small cell carcinoma. Staining for ACTH was negative; no stain for CRH was available. Two weeks after chemotherapy, 6:00 a.m. cortisol normalized and CT scans showed universal improvement. CONCLUSION Extensive literature details paraneoplastic syndromes associated with SCC, but we report the first case of EPSCC diagnosed due to onset of dual paraneoplastic syndromes.

Abstract
AIM To study clinical outcomes and management of lymph nodes extrapulmonary small cell carcinoma (LNEPSCC). METHODS Herein, we perform a systematic search of published literature in the PubMed and EMBASE databases for studies describing LNEPSCC. For uniformity of reporting, LNEPSCC was staged as limited if it involved either single lymph node station or if surgery with curative intent had been undertaken. The disease was staged extensive if it involved two or more lymph node regions. RESULTS The systematic literature review yielded eight descriptions (n = 14) involving cervical, submandibular and inguinal lymph nodes. Eleven (64.7%) patients had limited disease (LD) and six (35.3%) had extensive disease (ED) at presentation. Chemotherapy (n = 6, 35.3%) or surgery (n = 4, 23.5%) were the most common form of treatment given to these patients. Complete response was achieved in 12 (70.6%) of the patients. Median (interquartile range) progression free survival and overall survival was 15 (7-42) mo and 22 (12.75-42) mo respectively. Of the three illustrative cases, two patients each had ED at presentation and achieved complete remission with platinum based combination chemotherapy. CONCLUSION LNEPSCC is a rare disease with less than 15 reported cases in world literature. Surgical resection with curative intent is feasible in those with LD while platinum based combination chemoradiation is associated with favorable outcomes in patients with ED. Prognosis of LNEPSCC is better than that of small cell lung cancer in general.

Abstract
Background Neuroendocrine prostate cancer is rare but lethal. It is one of the most common extra pulmonary manifestations of small cell cancer. Case presentation Here we present a case report of a 53-year-old male who presents with a mixed adenocarcinoma and neuroendocrine prostate tumor on a background of previously normal prostate-specific antigen (PSA). His initial symptoms prior to diagnosis included decreased urine output and acute kidney injury (AKI). Conclusion Neuroendocrine tumor does not elevate the PSA level and hence is often a late finding with a poor prognosis. Special staining on histopathogy is required to reveal this diagnosis.

Abstract
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. The tumor was found to have invaded the right orbit and anterior cranial fossa. Metastases to cervical lymph nodes and bone were also found. Due to the extended stage and poor prognosis of the patient, the management plan is palliative chemoradiotherapy.
