Primary small cell neuroendocrine carcinoma of the oesophagus are extremely rare. Histopathologically these are usually high grade proliferative tumours. Typical clinical features have not been described, nor has standard therapeutic management been established, due to low incidence and scarcity of published data. We describe the case of a patient admitted to our hospital for dysphagia and hematemesis, diagnosed with primary small cell neuroendocrine carcinoma of the oesophagus.

Neuroendocrine neoplasms (NENs) are particularly rare in all sites of the gynecological tract and include a variety of neoplasms with variable prognosis, dependent on histologic subtype and site of origin. Following the expert consensus proposal of the International Agency for Research on Cancer (IARC), the approach in the latest World Health Organization (WHO) Classification System of the Female Genital Tumours is to use the same terminology for NENs at all body sites. The main concept of this novel classification framework is to align it to all other body sites and make a clear distinction between well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). The previous WHO Classification System of the Female Genital Tumours featured more or less the same principle, but used the terms ‘low-grade neuroendocrine tumor’ and ‘high-grade neuroendocrine carcinoma’. Regardless of the terminology used, each of these two main categories include two distinct morphological subtypes: NETs are represented by typical and atypical carcinoid and NEC are represented by small cell neuroendocrine carcinoma (SCNEC) and large cell neuroendocrine carcinoma (LCNEC). High-grade NECs, especially small cell neuroendocrine carcinoma tends to be more frequent in the uterine cervix, followed by the endometrium, while low-grade NETs usually occur in the ovary. NENs of the vulva, vagina and fallopian tube are exceptionally rare, with scattered case reports in the scientific literature.

Urothelial carcinoma with villoglandular differentiation (UCVGD) is a rare aggressive variant of urothelial carcinoma. It is usually associated with high-grade urothelial carcinoma or rarely adenocarcinoma. There is only one other previous report of UCVGD associated with small cell neuroendocrine carcinoma of urinary bladder. We report the second case of UCVGD with small cell neuroendocrine carcinoma of urinary bladder in a 74-year-old non-smoker male patient. The mass was muscle invasive and also invaded the prostate. This entity needs to be confidently diagnosed due to its prognostic and therapeutic implications.

Small cell carcinoma of the prostate is a rare neoplasm, with only a few series hitherto reported. A little less than half of the cases are associated with conventional acinar adenocarcinoma, which are usually high grade. Although consensus has not been reached, the majority of patients with small cell neuroendocrine carcinoma of the prostate have advanced disease at diagnosis and disproportionally low PSA levels compared to patients with conventional acinar adenocarcinoma. Treatment consists mainly of chemotherapy associated with surgery. Radiation therapy is reserved for selected cases. This study reviews the most up-to-date information on small cell carcinomas of the prostate.

Abstract Introduction/Objective Small cell neuroendocrine carcinoma (SCNEC) primary to the head and neck region, especially from oropharynx, is very rare. Published data have shown that Human papillomavirus (HPV) positivity may be associated with a better overall survival in these tumors. Here we report a case of p16 positive SCNEC arising from the tonsil. Methods/Case Report A 51-year-old man with former smoking history was evaluated for sore throat and difficulty swallowing. Nasopharyngolaryngoscopy showed a left tonsillar mass and imaging revealed left jugular chain lymphadenopathy with no other evidence of a primary tumor elsewhere, including the lung. Biopsy of the mass was performed which revealed nested proliferation of uniform, hyperchromatic tumor cells with scant cytoplasm, indistinct nucleoli, areas of nuclear molding, and brisk mitotic activity. No keratinization was present, but a vague peripheral palisade was seen in some of the nests. The major differential diagnostic considerations included HPV-related nonkeratinizing squamous cell carcinoma, basaloid squamous cell carcinoma, and SCNEC. Immunohistochemistry revealed tumor cells were positive for AE1/AE3 with partial dot-like perinuclear pattern, cytokeratin 8/18, synaptophysin, and strong p16; negative for P40, P63, cytokeratin 5/6, cytokeratin 7, chromogranin, and CD56. Because SCNEC at any site may be positive for p16, testing for HPV RNA by in-situ hybridization was performed and showed negative for HPV subtypes 6, 11, 16, and 18. Results (if a Case Study enter NA) NA Conclusion This case highlights the differential diagnosis of a “basaloid” appearing carcinoma in the oropharynx. It also reinforces the fact that although p16 is considered a reliable surrogate marker for HPV infection in oropharyngeal squamous cell carcinoma, the same does not hold true for SCNEC.
