Pulmonary benign metastasizing leiomyoma (PBML) is a rare entity. We herein report a case of PBML found as multiple bilateral lung nodules 11 years after total hysterectomy. The patient was a 53-year-old woman with past surgical history of abdominal total hysterectomy for a uterine leiomyoma at the age of 42. She was referred to our department for further evaluation of multiple pulmonary nodules detected by a chest radiography. A chest computed tomography revealed multiple bilateral small lung n...

AIM: Follicular pancreatitis is a recently recognised, distinct clinicopathological entity characterised by the presence of many intrapancreatic lymphoid follicles with reactive germinal centres. However, the clinicopathological and immunological features and causes have not yet been established. We assessed the clinicopathological and immunological profiles of patients with follicular pancreatitis who underwent surgery. METHODS AND RESULTS: This study included three patients with pancreatic mas...

Abstract Immune checkpoint mechanisms such as the programmed cell death-ligand 1-programmed cell death 1 (PD‑L1-PD‑1) axis are utilized by tumor cells to evade the cytotoxicity of effector immune cells. However, environmental factors responsible for the expression of PD‑L1 on tumor cells remain to be fully elucidated. We hypothesized that an immunological interaction with tumor-infiltrating CD8+ lymphocytes (CD8+ TILs) would contribute to PD‑L1 expression in tumor cells. To verify this hypothesi...

Lymphoepithelioma-like carcinoma is a particular form of undifferentiated carcinoma characterized by a prominent lymphoid stroma that was originally described in the nasopharynx. We present a case of hepatitis C virus (HCV)–associated lymphoepithelioma-like cholangiocarcinoma (LEL-CC), located at the liver, in a patient with history of malignancy. A 79-year-old man underwent partial hepatectomy with lymphadenectomy for a suspected metastasis of colon cancer 2.5 years after hemicolectomy for adva...

Background Invasive micropapillary carcinoma (IMPC) is a distinct histopathological variant of breast carcinoma and frequently develops lymph node metastases. CD44 is a family of transmembrane glycoprotein receptors with multiple variant isoforms (CD44v), which have tissue-specific expression. Previous studies have demonstrated a loss or gain of CD44v and CD44 standard form (CD44s) expression in breast carcinomas. In this study, we analyzed the immunoprofiles of CD44s, CD44v6, and CD44v9 in IMPC...

Introduction The contribution of programmed cell death ligand-1 (PD-L1) immune checkpoint molecule toward progression of non-small cell lung cancer (NSCLC) has not yet been elucidated, in part, because of lack of a standardised method to evaluate PD-L1 expression. In this study, we developed a novel method for the evaluation of PD-L1 expression on NSCLC cells and examined its correlation with clinicopathological characteristics. Methods After immunohistochemical examination of PD-L1 expression f...
