Giant Cervical Lymphangioma Extending from Skull Base to Clavicle- A Rare Case

Lymphangiomas are congenital benign lesions commonly seen in pediatric age group with a rare occurrence in the region of head and neck, commonly presenting as asymptomatic masses. Cervical lymphangioma is a rare entity among adults, and giant sized lymphangiomas in this region have sparse mention in literature. This case report describes the rare presentation of a giant cervical lymphangioma and the challenges involved to treat such masses in the region of head and neck. We encountered a rare case of a 52 year old female who presented with a 10 × 5 cm swelling in the right posterior triangle of neck swelling since 6 months extending from skull base up till clavicle. Pathological and radiological entities confirmed the lesion as a “giant cervical lymphangioma”. Head and neck lymphangiomas are congenital lesions of benign origin. Lymphangiomas have been classified as macrocystic if larger than 2 cm, and microcystic if less than 2 cm. Our description of a macrocystic 10 × 6 cm lesion is hence definitely one of the largest cervical lymphangiomas encountered till date. It’s a problematic and arduous plan of treatment for such masses in head and neck with a high chance of recurrence if incompletely removed.
