Conjunctival Myxoma: Series of 3 Cases of a Rare Ocular Tumour

Abstract

Conjunctival myxomas are very rare benign tumours of mesenchymal origin which pose a diagnostic challenge clinically and radiologically. They usually present as asymptomatic slowly growing cystic lesions involving the bulbar conjunctiva. Two cases were with usual presentation while one was with unusual presentation. Two cases of conjunctival myxoma (59 year old female patient and 65 years old male patient) involving the bulbar conjunctiva and one (56 years old female patient) in the palpebral conjunctiva are reported. Anterior segment examination and fundoscopy were within normal limits. A clinical diagnosis of conjunctival cyst, pinguecula and pyogenic granuloma was made in the three cases, respectively. Excision was done in all the cases and a diagnosis of myxoma was made based on the characteristic histological and immunohistochemical features. No systemic involvement was seen. The authors hereby report the present cases because of their rarity and to emphasise that, histopathology is required to distinguish it from other conjunctival lesions.
