Abstract

Primary malignant lymphoma of the parotid gland is extremely rare entity and seldom described in the literature. Extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue(MALT lymphoma) is a relatively indolent disease and tents to remain localized for prolonged period of time. MALT lymphoma can be diagnosed after immunohistopathological study. Clinically, most MALT lymphomas are localized at the time of diagnosis and may be curable with local therapy alone, either surgery or radiotherapy. We present a case of MALT lymphoma in both parotid glands of patient who detected a left infraauricular huge mass as a first symptom and underwent surgical excision and immediate reconstruction using sternocleidomastoid myocutaneous flap.
