Objective: The study of the cyto-histological characteristics of abundant tumours of salivary glands (TSG).

Methods: Sixty-six reagents of TSG were studied. Carried out cytological (colouration of Romanovsky-Giemsa) and histological studies (staining with hematoxylin-eosin) with light-optical microscopy (Carl Zeiss Primo Star) with an increase of 10-40 hundredfold. The material was processed by the variational statistics method. All data are presented in the form of shares (%).

Results: With the cytologic recording of benign TSG from 36 reagents in 16 cases were detected erythrocytes (red cells), as well as single leukocytes (white cells) and two-dimensional epithelium without atypia, in 10 – proliferating cubic epithelium, in 6 – polymorphic adenoma, in 3 – a turban tumour, in 1 – a lymphosarcoma. In malignant TSG from 28 reagents in 8 cases the picture of a carcinoma was found out, in 8 – erythrocytes and proliferating cubic epithelium, in 6 – a turban tumour, in 6 – adenocarcinoma. Morphological studies have established in the following: in benign TSG of 36 reagents pleomorphic adenoma was detected in 31, monomorphic adenoma in 4, adenolymphoma in 1 case; in malignant TSG of 28 reagents abundant the turban tumour and adenocarcinoma (in 12 cases), epidermoid cancer was detected in 2 and moderately differentiated cancer, also in 2 cases.

Conclusions: In benign TSG polymorphic adenomas were more often detected, because of mixed and composite structure and tumour transformation of tumour cells are the variant of renewal tumour cells and malignization. Among malignant TSG the turban tumours and adenocarcinoma were more common; morphologically tumours are similar to each other, but in the definition of turban tumours, adenocarcinoma is a tumour with a nondifferentiated variant and often gives invasion to neighbouring cells and is metastasized.

Keywords: Benign and malignant tumours, salivary gland, histological examination, cytological examination.
