Multiple Limbal Cysts: An Unusual Presentation of Squamous Cell Carcinoma of Conjunctiva

Abstract

Introduction: Squamous cell carcinoma of conjunctiva or cornea is a rare entity with varying clinical presentations. Often it is misdiagnosed as pterygium and undertreated. Presentation: An unusual case of 40 year old male, vendor by occupation with multiple cystic lesions with partly gelatinous surface on left eye limbus from 7’o clock to 9’o clock position. It also had a prominent, tortuous blood vessel supplying the lesion. Excision biopsy with 2 mm of healthy conjunctiva was carried out with cryotherapy. Histopathological examination confirmed our diagnosis of invasive squamous cell carcinoma. Eye drop Mitomycin C (0.02%) was instituted for a total of 4 weeks with midcycle interval of one week. As the course of MMC finished, another cryo application was done. Conclusion: Squamous cell carcinoma can present in various clinical picture like in our case it presents uniquely as a cystic mass which has not been described in literature. After excision biopsy, cryotherapies with topical Mitomycin C are effective methods to prevent recurrence.
