CONTEXT The discovery and subsequent ultrastructural characterization of the interstitial Cajal like cells (now called telocytes) in virtually every anatomic sites of the human body, by Laurentiu M Popescu and co-workers, have dramatically improved the understanding the function of these cells and pathogenesis of extragastrointestinal stromal tumors (EGIST). Pancreatic extragastrointestinal str...

Abstract The polymorphous low-grade neuroepithelial tumor of young (PLNTY) is considered as one among the tumor; per WHO-2021 classification Brain Tumors in fifth edition. term PLNTY was first coined by Huse 2016. These morphologically variable tumors are characterized their oligodendroglioma-like cellular components, infiltrative growth pattern, and Cluster Differentiation 34 (CD34) immunoposi...

Background. Craniopharyngiomas are benign epithelial tumors. According to embryogenetic theory, these neoplasms develop from the remains of cells Rathke’s pouch, which connects cavities primary oral tube with pituitary gland in embryonic period. The metaplastic theory assumes occurrence craniopharyngiomas as a result metaplasia chiasmal-sellar region. Objective. To present clinical case ectopic...

Indocyanine green (ICG) shows promise for diagnosing and treating tumors due to its good photothermal fluorescent properties. In this study, sodium heparin (SH)-stabilized ICG/nano-hydroxyapatite (SH-ICG/nHAP) suspension was ultrasonically prepared achieve photodynamic collaborative therapy (PTT/PDT) tumors. The nHAP had a short rod-like shape drug-loading capacity of 13.3% ICG, corresponding e...

PURPOSE The aim of this study was to identify the ultrasound features and clinicopathological characteristics of basal-like subtype of triple negative breast cancers (TNBCs). MATERIALS AND METHODS This study was approved by the ethical board of the Second Affiliated Hospital of Harbin Medical University. The patients' clinicopathological information was available. The ultrasound features of 6...

A number of tumors and tumor-like non-neoplastic lesions with different cell types on histology occur in the skull base. A wide variety in disease and lesion appearance often complicates the process of radiological diagnosis. The main role of radiographic imaging is the detection and characterization of skull base lesions, with evaluation of the extent of invasion or preservation of adjacent cr...
