Profile of ocular and adnexal tumours at a tertiary institute of northeast India.

Purpose: To present the profile of patients with ocular and adnexal tumours presenting at a tertiary eye care institute in northeast India in ten years between 2003 and 2013.

Design: Hospital based retrospective review of medical records.

Method: The clinical history, site of involvement and pathological diagnoses were retrieved from ocular pathology registers from October 2003-October 2013. This included conjunctival, orbital, adnexal and intraocular tumours. All specimens were fixed, processed and stained. Immunohistochemistry was carried out where ever indicated to come to a final diagnosis.

Results: In all 1003 cases were included in our study, with 622 (62.01%) benign tumours and 381 (37.98%) malignant tumours. 54.63% were males and 45.36% were females. Amongst the conjunctival tumours, squamous cell carcinoma (SCC) (72.5%) and nevus (39.6%) were the most common malignant and benign tumour, respectively. Non-Hodgkin's lymphoma (NHL) (60%) was the most common malignant orbital tumour. Retinoblastoma (RB) (81.5%) was the most common intraocular malignancy, followed by melanoma (18.4%). Basal cell carcinoma (BCC) (35.1%) was the most common malignancy in the lid.

Conclusion: NHL and SCC were the most frequently seen malignant tumours in adults while RB was the most common intraocular tumour in children.
