RESUMO
Forty-two cases of orbital lesions in superolateral quadrant were evaluated in our study by fine needle aspiration biopsy. Cases were histologically proven wherever possible. In 92.85% cases the diseases were correctly diagnosed. Females were mainly affected. Lymphomatous tumours were diagnosed on the basis of atypical lymphoid proliferation, correlated with clinical features and findings of computed tomographic scan and managed by radiotherapy. Pseudotumours, dermoid and epithelial tumours of lacrimal gland were diagnosed accurately except in one case of malignant mixed tumour where the malignant component was aspirated. Pseudotumours were treated by steroid, dermoid by excision. In case of adenocarcinoma and adenocystic carcinoma, tumour masses were removed by lateral orbitotomy and radiotherapy was applied when bony erosion was present. One case of eosinophilic granuloma was treated by radiotherapy and curettage. The suspected case of intra-osseous cavernous haemangioma did not turn up for treatment.
