Perineural invasion in tumors is typically indicative of malignancy. There are exceptions in most organ systems, but interpretation is complicated when the tumor in question also mimics malignancy. An example of this challenge is found in the interpretation of sclerosing epithelial tumors of the skin. The differential diagnosis for this category of tumors includes malignant entities such as inf...
BACKGROUND Prostate cancer is the second most common malignancy among men worldwide and the sixth cause of cancer-related death. Some authors have reported a relationship between perineural invasion (PNI), Gleason score, and the invasion of peripheral organs during prostatectomy.

Adenoid cystic carcinoma (ACC) is a malignant neoplasm that commonly arises in the major or minor salivary gland and usually forms mass lesions. Here, we report a case of ACC involving a 56-year-old man, who displayed right multiple cranial nerve palsies with ipsilateral severe facial pain but not any mass formation. Right submaxillary gland biopsy after repeated challenges at last revealed the...
OBJECTIVE Perineural invasion of cholangiocarcinoma happens in the early stage of the disease but is often not recognized until its later stages. Research about the behaviour and mechanism of perineural invasion by cholangiocarcinoma is urgently needed for a useful new model. The aim of this work is to establish a novel model to address the problem. DESIGN Neural cells and cholangiocarcinoma ...
