Conjunctival primary acquired melanosis is a flat brown pigmentation on the surface of the eye, generally recognized in adults. It carries a risk to evolve to malignant melanoma.
Early treatment is important, especially when the tumor is small.
Melanoma can invade into the eye and orbit, requiring extensive surgery. The clinical diagnosis of a conjunctival tumor is best made at slit lamp biomicroscopy by an experienced clinician, familiar with conjunctival tumors and simulating lesions. Risk factors for metastatic spread from conjunctival melanoma have been identified and published by the Oncology Service. Treatment Excisional biopsy using partial lamellar scleroconjunctivectomy is the treatment of choice for most conjunctival tumors. Cryotherapy, alcohol epitheliectomy and alcohol sclerectomy is also applied.
