Mucosa-associated lymphoid tissue lymphoma presented as diffuse swelling of the parotid gland.
Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct subtype of lymphoma. Parotid MALT lymphoma is a rare tumor that is hard to diagnose by fine-needle aspiration cytology. Therefore, partial parotidectomy is often required for a pathological diagnosis. We report a case of MALT lymphoma presented as unilateral diffuse swelling of the parotid gland, who was diagnosed by partial parotidectomy and underwent radiotherapy.
