In rare cases, ACC undergoes high-grade transformation, which is associated with poor prognosis, in contrast to relatively long survival in the conventional ACC. 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. A suspect lymph node was sent to freeze section histology. Large non-cohesive cells with vesicular nuclei and prominent nucleoli along with well persevered lymph node architecture were seen in the frozen slide. This finding lead to suspicion of a lymphoma, the surgery finished in the extent of superficial parotidectomy and selective neck dissection of regions II-IV. 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. To the best of our knowledge, the high-grade ACC of the parotid gland was reported only in 10 cases in the medical literature.</p>","PeriodicalId":9861,"journal":{"name":"Ceskoslovenska patologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38506226","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}

Pulmonary thrombembolism affects the right ventricle. Two morphologically and clinically distinct conditions are distinguished according to change of blood pressure and speed of blood pressure increase in the pulmonary artery - acute and chronic cor pulmonale. Acute cor pulmonale develops during rapid increase (within seconds) of blood pressure in the pulmonary artery. Morphologically, the condition leads to dilatation of the right ventricle and clinically to sudden cardiac death or severe circulatory instability. Chronic cor pulmonale represents myocardial hypertrophy of the right ventricle as a response to the gradually increasing pressure in the pulmonary artery. Herein, we demonstrate a rare case report of right ventricular myocarditis in a 51-year-old woman with pulmonary thromboembolism and morphological signs of chronic pulmonary hypertension. This non-infectious myocarditis is histologically characterized by myocardial damage (myocytolysis) and dominant histiocytic and neutrophil infiltration accompanied by scanty T-lymphocytes.
