High ‐grade transformation/dedifferentiation of an adenoid cystic carcinoma of the minor salivary gland to myoepithelial carcinoma
High‐grade transformation (HGT)/dedifferentiation is an unusual phenomenon in salivary gland carcinomas. Here we report a case of adenoid cystic carcinoma (ACC) with HGT/dedifferentiation to myoepithelial carcinoma, occurring in the epipharynx of a 42‐year‐old woman. The surgically resected tumor was a pedunculated mass, 31 × 25 mm in size, which had two histologically distinct carcinomatous areas, including a high‐grade sarcomatoid area composed of pleomorphic spindle cells and an area consisting of low‐grade typical ACC. These two components gradually changed from the low‐grade to the high‐grade comp...

Spheroid ‐type of AL amyloid deposition associated with colonic adenocarcinoma: A case report with literature review
We report a colonic adenocarcinoma associated with diffuse submucosal deposition of a peculiar spheroid‐type amyloid identified in the colon, terminal ileum, and appendix. A 65‐year‐old woman with past medical histories of hypertension, and chronic obstructive pulmonary disease, presented to the emergency room with cramping abdominal pain and nausea. A computed tomography (CT) scan of abdomen showed right colonic volvulus. Emergency right hemicolectomy was performed. The specimen showed colonic adenocarcinoma with focal submucosal invasion (pT1) arising from a villotubular adenoma. A diffuse submucosal spheroid‐typ...

Participation of delta annexin A3 in the ribosomal protein S19 C ‐terminus‐dependent inhibitory mechanism of the neutrophil C5a receptor through delta lactoferrin
Although C5a receptor (C5aR) interacting with its agonist C5a promotes acute inflammation during the initiation phase, the roles of the recycling C5aR during the resolution phase are still unclear. We found that C5aR interacted with its antagonist/agonist ribosomal protein S19 (RP S19) polymer or a RP S19 polymer functional analogue S‐tagged C5a/RP S19, which connects an RP S19 C‐terminus (IAGQVAAANKKH) to the S‐tagged C5a C‐terminus, promoted acute inflammation at the resolution phase via an activation of the apoptosis‐inducing transcription factor delta lactoferrin (δLf) in neutrophils and the membrane mobiliz...

An extremely rare case of Epstein ‐Barr virus‐associated gastric carcinoma with differentiation to neuroendocrine carcinoma
We report herein the case of a 78‐year‐old man with multiple simultaneous EBVGCs revealing different histopathologic morphologies; one was mixed adenoneuroendocrine carcinoma (MANEC), and the other was GCLS. Both tumor types exhibited positive results for EBV in situ hybridization. To the best of our knowledge, this represents the first report of EBVGC showing neuroendocrine differentiation. Immunohistochemistry also revealed a loss of gastrointestinal features, including CDX2, MUC5AC, and MUC6 expression, among tumor cells from the neuroendocrine component of the MANEC. We describe the pathologic features of this rare...

Plasma ‐activated medium (PAM) kills human cancer‐initiating cells
Medical non‐thermal plasma (NTP) treatments for various types of cancers have been reported. Cells with tumorigenic potential (cancer‐initiating cells; CICs) are few in number in many types of tumors. CICs efficiently eliminate anti‐cancer chemicals and exhibit high‐level aldehyde dehydrogenase (ALDH) activity. We previously examined the effects of direct irradiation via NTP on cancer cells; even though we targeted CICs expressing high levels of ALDH, such treatment affected both non‐CICs and CICs. Recent studies have shown that plasma‐activated medium (PAM) (culture medium irradiated by NTP) selectively induce...
