Introduction. Primary cutaneous CD4+ lymphoproliferative disorder of small and medium cells (PC T-LPD small/medium cell) is a new entity identified in the WHO classification published 2017. The aim research was to characterize morphological immunohistochemical features PC cell. Materials methods. study examined 28 skin biopsies from 13 males 15 females with cell using histological Results. We d...

Mammary ductal carcinoma in-situ (DCIS), a malignant appearing lesion on cytological and histological grounds, is in fact a non-obligate precancer. DCIS is difficult to manage and is sometimes treated more aggressively than invasive carcinoma. Although most DCIS classifications take into account the architectural growth pattern, when it comes to architecture, the literature is full of contradic...

The incidence of intrahepatic cholangiocarcinoma (iCCA) is highest in Eastern countries, such as Thailand, South Korea, and China, but its mortality are increasing worldwide. Over recent decades, the worldwide age-standardized for iCCA has been steadily increasing, whereas that perihilar CCA distal decreasing. macroscopic growth pattern somewhat different according to anatomic location tumor. c...

background primary small round blue cell tumors (srbct) in sinonasal comprise histogenetically diverse entities with overlapping morphologic features. because of the limited initial biopsy tissue materials, differential diagnostic difficulties may arise, and as they have different management, exact diagnosis and classification are very important. conclusions the results of our study indicate th...

DNA ploidy of 100 early gastric carcinomas (T1) was analysed by flow cytometry on archival material from five European centres and was correlated to morphological features and clinical behaviour. Tumours were classified according to the macroscopic appearance, histological type, and growth pattern. Aneuploidy was observed in 39% of tumours. Aneuploidy was more frequent in submucosal than in muc...
