Abstract
Background Pulmonary carcinoid tumors rarely coexist with non-small cell lung carcinoma, and only nine cases have been reported previously. The pathogenesis and origin of these combined tumors remain unclear because of its rarity. Case presentation We examined two cases of adenocarcinoma coexisting with a typical or atypical carcinoid tumor: Case 1 was a 77-year-old woman and Case 2 was an 83-year-old woman. Both of these cases had no respiratory symptoms, and underwent pulmonary lobectomies due to incidentally detected lung nodules. Recurrence and metastases were not detected after the surgery. Histologically, carcinoid and adenocarcinoma components were present in both cases. The two components coexisted without mixing with each other. Next-generation sequencing was performed on the two components in these cases. In each case, no common genetic variants were detected. Conclusion We considered that our cases could histologically and genetically represent collision tumors that did not share common progenitor cells. Comprehensive analyses such as whole genome sequencing could provide important information for elucidating the pathogenesis of adenocarcinoma and carcinoid components.

Abstract
A 71-year-old Japanese male patient presented with a rare case of Glomangiopericytoma (GPC) of the left nasal with obstruction. Complete resection with endoscopic surgery was performed. Immunohistochemical staining for smooth muscle actin, β catenin, cyclin D1, vimentin, and factor 13 were helpful in establishing a definitive diagnosis. Extranasal treatment has been traditionally performed for successful management. However, recent advances in endoscopic treatment have enabled complete endoscopic resection of GPC, minimizing morbidity and facilitating subsequent surveillance for recurrence. Endoscopic management should be considered in suitable cases.

Abstract
In chromaffin cells, tyrosine hydroxylase (TH), aromatic L-amino acid decarboxylase (AADC), dopamine β-hydroxylase (DBH), and phenylethanolamine N-methyltransferase (PNMT) are mainly involved in catecholamine synthesis. In this study, we evaluated the association between the status of catecholamine-synthesizing enzymes and histopathological features of pheochromocytoma and extraadrenal paraganglioma with special emphasis upon their postoperative clinical behavior. Immunohistochemical evaluation of TH, DBH, AADC, PNMT, Ki 67, and S-100 was performed in 29 pheochromocytoma and 10 extraadrenal paraganglioma and one lymph node harboring metastatic pheochromocytoma. Among these cases, metastasis was subsequently developed in three cases. Urinary normetanephrine (U-NM) levels were significantly higher in clinical metastatic cases than non-metastatic ones. Ki 67 labeling index was significantly higher in both clinical metastatic cases and the Adrenal Gland Scaled Score (PASS) score of ≧ 4 cases than PASS < 4 cases, although this score was originally used in pheochromocytoma. H-score of AADC and DBH were significantly lower in PASS ≧ 4 cases than those with < 4 cases, and in the cases associated with intratumoral necrosis (n = 4), the presence of spindle shaped tumor cells (n = 4), and large nests of cells or diffuse growth (n = 5). Lower status of intratumoral AADC could be related to poor differentiation of tumor cells in both catecholamine production and morphology and could be related to aggressive biological behavior of both pheochromocytoma and extraadrenal paraganglioma.

Abstract
Aldosterone is one of the mineralocorticoids synthesized and secreted by the adrenal glands, and it plays pivotal roles in regulating extracellular fluid volume and blood pressure. Autonomous excessive aldosterone secretion resulting from adrenocortical diseases is known as primary aldosteronism, and it constitutes one of the most frequent causes of secondary hypertension. Therefore, it is important to understand the molecular mechanisms of aldosterone synthesis in both normal and pathological adrenal tissues. Various factors have been suggested to be involved in regulation of aldosterone biosynthesis, and several adrenocortical cell lines have been developed for use as in vitro models of adrenal aldosterone-producing cells, for analysis of the underlying molecular mechanisms. In this review, we summarize the available reports on the regulation of aldosterone biosynthesis in the normal adrenal cortex, in associated disorders, and in in vitro models.

Abstract
It has become important to evaluate the possible involvement of 3β-hydroxysteroid dehydrogenase type 1 (HSD3B1) and 2 (HSD3B2) isoforms in aldosterone-producing adenoma (APA). In this study, we studied 67 and 100 APA cases using real-time quantitative PCR (qPCR) and immunohistochemistry, respectively. Results of qPCR analysis demonstrated that HSD3B2 mRNA was significantly more abundant than HSD3B1 mRNA (P < 0.0001), but only HSD3B1 mRNA significantly correlated with CYP11B2 (aldosterone synthase) mRNA (P <0.0001) and plasma aldosterone concentration (PAC) of the patients (P <0.0001). Results of immunohistochemistry subsequently revealed that HSD3B2 immunoreactivity was detected in the great majority of APA but a significant correlation was also detected between HSD3B1 and CYP11B2 (P <0.0001). In KCNJ5 mutated APA, CYP11B2 mRNA (P <0.0001) and HSD3B1 mRNA (P = 0.011) were significantly higher than those of wild type APA. These results suggest that HSD3B1 is involved in aldosterone production, despite its lower levels of expression compared with HSD3B2, and also possibly associated with KCNJ5 mutation in APA.

Abstract
An inhibitory mechanism toward gastrin hypersecretion is significantly different between G-cell hyperplasia and gastrinoma despite the common clinical manifestations; hypergastrinemia and its related persistent gastric ulcers. We recenlty studied the G-cell, d-cell and ECL-cell density in a case of G-cell hyperplasia. The 70-year-old patient has been treated for persistent gastric ulcers with a markedly increased plasma gastrin (5600 pg/mL). The stomach was surgically resected because of the obstruction associated with ulcer scars. The number of G-cells in the pyloric glands was quantified on the surgical specimens and G-cell hyperplasia was histolopathologically identified. Immunostainig of histidine decarboxylate revealed the presence of ECL-cell hyperplasia in the pyloric glands and its density was significantly and positively correlated with G-cell density. Somatostatin immunoreactive cells (D-cells) increased in their number in the oxyntic glands. These results all indicated that hypersecretion of gastrin in G-cell hyperplasia could induce ECL-cell proliferation in a paracrinal manner. In addition, relatively non-prominent endocrinological features in the G-cell hyperplasia compared to gastrinoma could be also related to the paracrinal somatostatin inhibitory effects upon ECL-cells in the pyloric glands.

Abstract
Renal epithelioid angiomyolipoma (EAML) is a potentially malignant tumor type whose characteristics and biomarkers predictive of malignant behavior have not been elucidated. Here, we report three cases of renal EAML with malignant features but without histories of tuberous sclerosis complex. Case 1 involved a 29-year-old man with a 12-cm solid mass in the right kidney who underwent radical right nephrectomy. Case 2 involved a 22-year-old woman with a retroperitoneal mass who underwent radical right nephrectomy and retroperitoneal tumorectomy. Local recurrence was detected 7 years post-surgery. Case 3 involved a 23-year-old man with a 14-cm solid mass in the left kidney who underwent radical left nephrectomy. Microscopically, the tumors in all cases demonstrated proliferation of epithelioid cells with atypia, mitotic activity, necrosis, hemorrhage, and vascular invasion. Epithelioid cells in all cases were immunohistochemically positive for melanocytic and myoid markers and weakly positive for E-cadherin and β-catenin. Immunohistochemistry revealed activation of the mammalian target of rapamycin pathway. Here, we report the morphological and immunohistochemical features of clinically or histologically malignant renal EAML.

Abstract
The great majority of the cases clinically diagnosed as primary aldosteronism (PA) have been caused by aldosterone-producing adenoma (APA) or idiopathic hyperaldosteronism (IHA). The differential diagnosis of both subtypes of PA is important due to the different therapeutic modes but clinically it is sometimes difficult. It is also important to understand the morphological features of these two subtypes with special emphasis upon differences of the status for aldosterone biosynthesis. In the last decade, molecular mechanisms of PA including the aberrant expression of G-protein coupled receptors (GPCRs), key regulators of the intracellular calcium signaling pathway and somatic mutations of ion channels, have been revealed and our understanding of the molecular pathways involved in excessive aldosterone production has been markedly advanced. In addition, newly developed monoclonal antibodies specific to the isoform of adrenal steroidogenic enzymes have demonstrated the novel profiles of adrenal steroidogenesis in PA. These novel findings indicate that the molecular mechanisms on the onset and pathophysiology of PA are more complicated than previously considered and further clarification of clinical relevance of these findings is required at this juncture.

Abstract
Demyelinating polyneuropathy associated with amyotrophic lateral sclerosis (ALS) is quite rare. We herein present the case of a woman patient with a 12-year history of chronic inflammatory demyelinating polyneuropathy (CIDP)-like polyneuropathy who later developed bulbar palsy and respiratory failure. The autopsy findings revealed neuronal loss in the anterior horn and primary motor cortex with degeneration of the corticospinal tracts. Diffuse phosphorylated TAR DNA-binding protein of 43 kDa inclusions were observed in the anterior horn and cerebral cortices, including the temporal lobe. The final diagnosis was ALS with CIDP-like polyneuropathy. Compared with other reports of ALS with CIDP-like polyneuropathy, the present patient was younger and followed a relatively long clinical course, with no upper motor neuron signs.
