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

Abstract

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.

Pediatric follicular lymphoma of the parotid gland

“…As Park et al [10] stated in their case report of parotid lymphoma, the standard surgical procedure for PFL requires en bloc excision of the mass with superficial parotidectomy. This is because direct infiltration into the parotid gland parenchyme is occasionally found in postoperative pathology, although PFL is not a true parotid gland neoplasm [4,11]. Due to the patient’s young age and well-differentiated cellular morphology, local radiotherapy rather than systemic chemotherapy was chosen for adjuvant treatment.…”
