Primary amyloidosis of the conjunctiva and eyelid is a rare and often misdiagnosed condition. It is characterized by the deposition of insoluble amyloid fibrils, which are misfolded proteins, in the body. Amyloidosis can be systemic or localized with different types of amyloid fibril proteins identified using mass spectrometry. Ocular involvement in amyloidosis can lead to corneal dystrophies, glaucoma, vitreous opacities, and other symptoms. Diagnosis involves clinical examination and histopathological assessment. Treatment options depend on the extent of involvement and may include surgical excision, glaucoma management, vitrectomy, or liver transplantation in rare cases. We present a rare case of localized conjunctival amyloidosis initially misdiagnosed as pyogenic granuloma, with clinical symptoms of ptosis, periorbital swelling, and conjunctival lesions. The patient underwent excision of the lesions, and subsequent evaluation did not reveal systemic amyloidosis. Ocular amyloidosis requires careful diagnosis and consideration of systemic involvement for appropriate management.
