Zemun hospital, the present-day Clinical Hospital Zemun-Belgrade, was founded in 1784, is the oldest hospital in the Serbia. For over two centuries, it blazed the trial and still pioneers in the application of numerous advanced medical achievements and knowledge in this region.

The development of Zemun Hospital in the 19th century was followed by better work conditions and an increasing number of patients. The arrival of doctor Vojislav Subotić to the hospital and his work were key moments in the general improvement of the hospital. Since 1887, the hospital was administered by a society known as „Sisters of Charity of Saint Vincent De Paul“. By the end of 1891, they had constructed a new hospital building.

The 20th century was the most eventful period in the history of Zemun Hospital and it brought many changes. Working through out both world wars, the hospital staff aided those who were wounded or ill, both soldiers and civilians. Throughout this period, the hospital worked in three different countries, under various administrations and owners.

The aim of our study was to determine using immunohistochemical method profi and relationship between lymphocytes in lymphoid rich stroma of the Warhins tumors, as well as, the relationship between lymphocytes and tumors epithelial cells. Our retrospective-prospective study we conducted in the Department of Clinical Pathology KBC Zemun on 25 samples of tissue from the parotid gland with WT tumor surgically removed at the Department of ENT KBC Zemun in the period from 2000 to 2016 year. Sections of tumor tissue, fixed in 10% formalin were stained with hematoxylin-eosin standard method, and then immunohistochemical method to: antibody B lymphocytes (CD20) antibody for T lymphocytes (CD3), keratin antibody that marks the basal and columnar epithelial cells (CK7 ) and keratin antibody that marks only the basal epithelial cells (CK5 / 6). We have found that in relation to the gender distribution of all 25 patients, there were more male patients: 16 (64%) men and 9 (36%) women. Immunohistochemical analysis with keratin antibody CK7 showed that luminal columnar cells intensely positive (+++) more than 75% in 23 cases (92%), whereas in 2 cases were intensely positive (+++) in percentages ranging from 25 to 75%. In contrast to the luminal, basal cells were always showed little immunoreactivity (+) antibody to CK7 and in 20 cases in the group of <25% of the cells respectively in the cases of 5% in the group 25-75. Evaluation of the presence, intensity, type and distribution of cells with each other and in relation to the tumor epithelial component would contribute to establishing unclear histogenesis lymphoid stroma at the tumor.

The same legal regulations applied for medical doctors involved in patients treatment, also refer to doctors that do not manage therapy, but whose professional activity is essential for providing adequate diagnostics. this group of professionals include pathologists, which is proven by the actual forensic practice. In modern medicine, the role of pathologists is of extreme importance in the diagnostics of many diseases. In this paper, based on presentation of particular cases from the forensic practice and literature data, the possible forms of mistakes in the work of pathologists and their associates are shown, as well as the causes and the consequences of such mistakes, together with the characteristics of the legal procedures and the significance of adequate medicolegal expertise in these cases.

The inflammatory myopathies are heterogeneous aquired diseases which are grouped together because of their imflammatory nature. In this group are included polymyositis, adult and juvenile dermatomyositis and inclusion body myositis. The aim of this review is to point out the basic principles od differential diagnosis of idiopathis aquired inflammatory myopathies. the general pathologists in the rutine practice are very often confronted with skin or muscle samples for many reasons, and so they have to be informed with these basic entities.
