Resumo: Lymphangiomas are benign formations of the lymphatic system characterized by dilated vascular channels filled with lymphatic fluid. The case refers to a 31-years-old man presented with an asymptomatic submandibular swelling that had been evolving for 8 years. Ultrasonography revealed irregular hypoechoic compartments in the right submandibular region suggestive of cystic lesions with retention of mucus or lymph. An incisional biopsy was performed and microscopic analysis revealed fibrous connective tissue fragments exhibiting discreet mononuclear inflammatory infiltration and vascular spaces of different calibers partially covered by a single layer of cells. The vascular wall presented disorganized bundles of muscle fibers and vascular-nerve bundles. Complete surgical resection was performed. Although lymphangiomas are rare in adults, they should be considered in the evaluation of cystic neck masses. This case highlights the importance of imaging and histological evaluation for accurate diagnosis and appropriate treatment of these lesions.
