Cervical Cystic Lymphangioma in an Adult: A Case Report

Cystic lymphangioma (CL) or cystic hygroma is a rare benign lymphatic malformation typically observed in children. Adult presentation is extremely uncommon and often leads to diagnostic difficulties. The head and neck region is the most common site of occurrence, although CL can be present elsewhere in the body including the axilla, mediastinum, groin, and retroperitoneum. Though rare in adults with only a few cases reported in the literature, cystic lymphangiomas should be included in the differential diagnosis of neck masses. Imaging is key to preoperative assessment, while surgical resection remains the cornerstone of treatment. We report a case of a 66-year-old male presented a cervical cystic lymphangioma, and discuss the presentation, diagnosis and management of this pathology.
