Background:Nevus of the bulbar conjunctiva is a benign pigmented lesion of the ocular surface.Unless a biopsy is required for ruling out malignant melanoma,a nevus is usually excised for cosmetic reasons only.However,with large lesions involving two or more quadrants of the bulbar conjunctiva,a total resection can be difficult.In this report,we present a case of a huge nevus treated by surgical excision and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva.Methods:A 54-year-old Japanese man was referred to our clinic with suspected malignant tumor of the bulbar conjunctiva in his right eye.A large and diffuse pigmented tumor with numerous small cysts was present mainly on the upper bulbar conjunctiva.Resection of the conjunctival tumor and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva were performed.Results:The histopathological diagnosis was conjunctival nevus.Epithelialization of the bulbar conjunctiva over the amniotic membrane sheet was completed 4 weeks after resection.At 44-month follow up,there was no recurrence or any postoperative complication.Conclusion:Surgical resection combined with reconstruction by amniotic membrane transplantation is effective for the treatment of large conjunctival nevus. Background: Nevus of the bulbar conjunctiva is a benign pigmented lesion of the ocular surface. Unnatural a biopsy is required for ruling out malignant melanoma, a nevus is usually excised for cosmetic reasons only. Despite, with large lesions involving two or more quadrants of the bulbar conjunctiva, a total resection can be difficult. In this report, we present a case of a huge nevus treated by surgical excision and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva. Methods: A 54-year-old Japanese man was referred to our clinic with suspected malignant tumor of the bulbar conjunctiva in his right eye. A large and diffuse pigmented tumor with numerous small cysts was present mainly on the upper bulbar conjunctiva. Resection of the conjunctival tumor and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva were performed.Results: The histopathological diagnosis was conjunctival nevus. Epithelialization of the bulbar conjunctiva over the amniotic me mbrane sheet was completed 4 weeks after resection. At 44-month follow up, there was no recurrence or any postoperative complication. Confluence: Surgical resection combined with reconstruction by amniotic membrane transplantation is effective for the treatment of large conjunctival nevus.
