Synchronous Lymphomas Arising in Ipsilateral Parotid and Submandibular Glands: Video-Assisted Surgery

The incidence of lymphomas in salivary glands is 5%, and it represents 10% of malignant salivary tumors. Synchronous tumors arising in different major salivary glands are not only very infrequent but also extremely rare; on the other hand, synchronous lymphomas in ipsilateral major salivary glands have not been reported previously. This article reports a case of synchronous lymphomas in mucosa-associated lymphoid tissue in the ipsilateral parotid and submandibular glands. Parotidectomy with facial nerve conservation and resection of the submandibular gland by video-assisted surgery using only a Blair-modified classic incision was performed. One year after the surgical procedure, the patient was followed up at regular intervals, and residual mucosa-associated lymphoid tissue lymphoma did not appear. This case illustrates the importance of the diagnostic possibility of synchronous primary tumors after identification of a simple one; this also reports the video-assisted resection of the submandibular gland using only a Blair incision, when a parotidectomy must be also made.
