conjunctival lymphoma
A malignant lymphoid tumor affecting the conjunctival tissue, often presenting as a salmon-pink mass.
Full Definition
Conjunctival lymphoma is a malignancy arising from lymphoid tissue within the conjunctiva, representing the most common primary conjunctival malignancy in adults. These tumors typically present as painless, salmon-pink or fleshy masses that may be mistaken for chronic conjunctivitis or other benign conditions. Most conjunctival lymphomas are of B-cell origin, with mucosa-associated lymphoid tissue (MALT) lymphoma being the most frequent subtype. Accurate diagnosis requires histopathological examination with immunohistochemical staining. Treatment options include radiation therapy, topical chemotherapy, or surgical excision depending on the extent and subtype of the lymphoma.
Usage
Usage note: Specify anatomical location within conjunctiva and histological subtype when available.
