A case of ovarian carcinoid tumor of the trabecular type is presented. The small carcinoid tumor was found incidentally in a resected dermoid cyst. Histologically, the tumor was surrounded by a smooth muscle layer with focal stromal invasion. Non-carcinoid papillary mucosa and a few small glands, simulating the mucosa of the fallopian tube and remnant müllerian glands, respectively, were also present adjacent to the carcinoid tumor and enclosed by the same smooth muscle layer. The tumor cells revealed argyrophilia, and were positive for peptide tyrosine tyrosine (PYY) in the cytoplasm and for CEA in part of the luminal surface. This case was considered to be a rare ovarian carcinoid tumor arising from a dermoid cyst, without association of struma ovarii. PYY may be a potential marker for determining the histogenesis of ovarian carcinoid tumors.

A novel molecular classification for small cell lung cancer (SCLC) has been established utilizing the transcription factors achaete-scute homologue 1 (ASCL1), neurogenic differentiation factor 1 (NeuroD1), POU class 2 homeobox 3 (POU2F3), and yes-associated protein 1 (YAP1). This classification was predicated on the transcription factors. Conversely, there is a paucity of information regarding the distribution of these markers in other subtypes of pulmonary neuroendocrine tumors (PNET).

Horseshoe kidney is a rare congenital anomaly with an unusually higher frequency of neuroendocrine tumors. Symptoms are rare, and, in most of the cases, are incidentally diagnosed. The clinical behavior of these tumors is heterogeneous and can be difficult to predict based on histology alone.

Introduction: Lung cancer is a major cause of cancer-related deaths, with 2 million new cases annually. Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise about 20 % of lung cancers, including typical carcinoid tumors (TC). While tobacco is a primary risk factor, non-tobacco factors also play a role.
