[Adenocarcinoma of nonpigmented ciliary body epithelium (clinical cases)].

The article presents two clinical cases of adenocarcinoma of nonpigmented epithelium of the ciliary body, which is a very rare malignant tumor of the organ of vision with distinctive features. Surgical treatment is necessary to verify this tumor and assess the degree of its aggressiveness in terms of the prognosis of the disease, with subsequent pathomorphological and immunohistochemical studies. The article also discusses the epidemiological aspects, morphological features, clinical manifestations of this pathological condition, as well as possible treatment options and features of follow-up monitoring of this group of patients.

Development of tumours in mice chronically infected with herpes simplex virus.

Tumours developed in chronic infection lasting for 150--180 days in 39 (60%) of 65 mice infected with strain L2 of herpes simplex virus (HSV) type 1 and in 12 (20%) of 60 mice infected with strain 333 of HSV type 2. Similar results were obtained in 150 immunosuppressed mice chronically infected with HSV types 1 and 2. Pathomorphologically, the neoplasias in the first group (strain L2) were similar to adenocarcinoma and malignant lymphoma and in the second (strain 333) to lymphoma and angio- or fibrosarcoma.
