Ligand-Receptor Interactions Between Squamous and Endothelial Cells Induce Head and Neck Squamous Cell Carcinoma.

Advances in narrowband imaging (NBI) have revealed that squamous epithelial lesions form alongside changes in squamous epithelial cells and intrapapillary capillary loops (IPCLs) in the head and neck. However, the molecular interactions between squamous epithelial cells and endothelial cells (ECs) that promote IPCL proliferation are unclear. This study aimed to identify the mechanisms of cooperation between parenchymal squamous cells and stromal IPCLs during the formation of head and neck squamous cell carcinoma (SCC).

Rhabdomyosarcoma With Fusion in the Scalp: A Rare Case Report Depicting Round and Spindle cell Morphology.

Rhabdomyosarcoma (RMS) is a nonepithelial malignant tumor that differentiates into immature skeletal muscle. It is currently classified into 4 main subtypes according to the WHO classification. However, based on clinicopathological and molecular findings, there has been an increasing number of cases that do not fit into any of these subtypes.
