Introduction

Lymphatic malformations (LM) are composed of dilated, abnormal lymphatic vessels classified as macrocystic (single or multiple cysts >2 cm3), microcystic (<2 cm3), or mixed. This patient is a 5-month-old with a right neck mass consistent with macrocystic lymphatic malformation on MRI. This low-flow vascular malformation required surgical intervention.

Methods

The site was marked in a natural skin crease. Subplatysmal flaps were raised and malformation was immediately encountered. Blunt soft tissue dissection was performed immediately adjacent to the mass to reflect tissue off the fluid-filled lesion. Neurovascular structures were preserved in this process. Mass was removed in total and Penrose drain and neck dressing were placed.

Results

A complete resection was performed. LM was confirmed on pathology. Patient is doing well with no deficits noted. The drain was removed after 1 week. One-month follow-up showed no recurrence.

Conclusion

Macrocystic lymphatic malformations are amenable to surgical resection at low risk and without recurrence.
