[Morphometric characteristics of tissue basophils in cancerous and precancerous diseases of the skin].

Skin of 60 patients with squamous cell non-keratinizing carcinoma, basaliomas, Bowen carcinoma, hyperkeratosis, papillomatosis and chronic inflammation was studied using routine histological and histochemical methods. The number of basophils was calculated; the index of their heparin saturation, degree of granulation was determined by division of a number of highly granulated labrocytes by a number of the least granulated labrocytes and multiplying the result by 100. The results may serve as a criterion in the evaluation of the degree of skin carcinoma cataplasia.

[Electron microscopic analysis of basal cell cancer of the skin].

Histologic and ultrastructural study of basal cell epithelioma was made. It has confirmed the correctness of WHO classification according to which the mentioned neoplasms are not subdivided into different histologic forms. Comparison of basal cell epithelioma with squamous cell carcinoma and skin epidermis has shown that morphologic differentiation in this case does not correlate with clinical stage of tumour malignancy.
