Parotid Lymphangioma: A Rare Diagnostic Puzzle in Head and Neck Pathology

Abstract

Introduction: Lymphangioma is a rare, benign lymphatic malformation, most commonly seen in children and infrequently involving the parotid gland in adults. Its presentation often mimics other parotid masses, posing a diagnostic challenge. Diagnosis is typically based on clinical examination, imaging, and confirmed by histopathology.

Case Report: A patient presented with a congenital swelling on the left side of the neck. Clinical examination revealed a soft, lobulated, mobile, non-tender mass measuring approximately 5×5 cm in the infra-auricular region extending to the mandibular area. Fine-needle aspiration cytology (FNAC) suggested a benign cystic lesion. Surgical excision was performed via a modified Blair incision under general anesthesia. The mass was sent for histopathological examination, which confirmed lymphangioma.The postoperative period was uneventful, and the patient was discharged in stable condition.

Discussion: Though rare, parotid lymphangioma should be considered in the differential diagnosis of parotid region masses in adults. A combination of clinical assessment, imaging, and histopathological evaluation is essential for accurate diagnosis and appropriate management.
