Malignant lymphoma is considered to be neoplasm of lymph node or lymphoid tissue. The head and neck resion is favorite site of this tumor, but intraoral presentation of lymphomas is an uncommon occurrence, and sublingual gland is extremely rare site. We report here a case of malignant lymphoma in the sublingual space. Malignant lymphoma is deficient in a clinical finding, and it is difficult diagnosis. At first, we performed ultrasonography for this case, and suspected it was a tumor not a cyst because significant blood flow was detected as a power Doppler signal in this lesion. It is said to be malignant 80% of a tumor to occur in sublingual gland. For reasons mentioned above, we doubted this lesion with a malignant tumor. The histological diagnosis was diffuse large B-cell lymphoma in the sublingual gland. We confirmed usefulness of power Doppler to differentiate the mass revealed occurred in this region.
