AAV represents a group of the most common systemic vasculitis in adulthood, and based on clinical manifestations this disease entity includes 3 phenotypes, namely: granulomatosis with polyangiitis (formerly Wegeners granulomatosis), microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome). Similar to other autoimmune diseases, AAV develops in patients with a predisposing genetic background who have been exposed to causative environmental factors, such as infections. The mechanisms by which ANCA antibodies cause vasculitis involves excessive neutrophil activation, that subsequently leads to release pro-inflammatory cytokines, reactive oxygen species and lytic enzymes. In addition, activated neutrophils induce the formation of neutrophil extracellular traps in a process called NETosis. The released neutrophil antigens are exposed to the immune system via antigen presenting cells, which further stimulates antibody production and creates a vicious circle with tissue destruction. Understanding the pathogenesis of AAV represents the key which provides not only optimal diagnosis and treatment, but also gives the pathologist a tool for deeper insight into the morphological features of disease progression, including the various stages of development and healing.</p>","PeriodicalId":9861,"journal":{"name":"Ceskoslovenska patologie","volume":"56 2","pages":"65-67"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38005855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional ACC is characterized by typical histopathology showing glandular arrangement with sharply demarcated lumina, the tumor cells have sparse cytoplasm and angulated hyperchromatic nuclei. ACCs undergoing high-grade transformation lack these morphological features. In this paper we present a case of 46 years old female patient presenting with locally advanced tumor of the parotid gland and neck lymphadenopathy, coming for surgery.

Large non-cohesive cells with vesicular nuclei and prominent nucleoli along with well persevered lymph node architecture were seen in the frozen slide.

Subsequent histopathological examination of formalin-fixed lymph node proofed epithelial nature of the atypical cells by p63 positivity. In the parotid gland resection specimen, an ACC with high-grade component was indentified. The high-grade ACC shared cell morphology with the lymph node metastasis. 17 from 20 lymph neck nodes contained metastases of high-grade ACC. Interestingly, there was strong CD117 expression in the high-grade ACC, whereas the conventional part was fully negative.
