Primary parotid lymphoma presenting as a recurrent cystic mass: A case report

A 15‐year‐old boy was diagnosed with a cystic parotid mass, which was initially thought to be a first branchial cleft cyst. The mass was treated with antibiotics and fully resolved on examination and imaging. The mass returned, and a superficial parotidectomy was performed to remove the suspected branchial cleft cyst. Final pathology demonstrated a B‐cell lymphoblastic lymphoma. Bilateral bone marrow biopsies and peripheral blood counts were negative for any malignancy. This case demonstrates a rare presentation of primary parotid B‐cell lymphoblastic lymphoma that began as a fluctuating cystic parotid mass consistent in appearance with a first branchial cleft cyst.
