The authors submit a review of histological findings and classification according to the TNM-classification of conjunctival tumours in patients under dispensary care at the First Ophthalmological Clinic of the Faculty Hospital and Medical Clinic of the Comenius University in Bratislava during a 10-year period (1989-1998). They included in the group 75 patients with clinically assessed conjunctival tumours (0.4% of the hospitalized patients). As to histological findings, 61 times (80.3%) a benign process was involved (naevus of the conjunctiva 12x) and 14x (19.7%) a malignant tumour, (7x times a primary malignant melanoma of the conjunctiva, 3x carcinoma). The authors recorded two relapses (one malignant melanoma of the conjunctiva, one melanoma penetrating into the orbit). The mean age of the patients was 47 years (from 1 to 82 years). In malignant melanoma of the conjunctiva stage T1 was detected in as many as 3/4 of the patients (6 times), whereby stage pT1, 2 was found in 7 patients. In carcinoma the authors did not detect stage T1, only stage T2 in 2 patients, T3 (pT3) in one patient.
