“…These vascular malformations are most commonly found in the head and neck (60%), but the incidence of parotid gland VLM is very rare [ 1 , 7 ]. Capillary, venous, and lymphatic malformations are slow-flow malformations, whereas arteriovenous malformations (AVMs) are fast-flow malformations [ 8 ].…”

Parotid lymphangioma is a benign lymphatic malformation commonly observed in infancy or early childhood. It often grows insidiously and presents as a painless, soft fluctuant mass. We report a case of an eight-year-old boy who was diagnosed from another center with right parotid lymphangioma of one-year duration. He presented with right painful preauricular swelling and trismus for nine days after a recent history of blunt trauma to the preauricular caused an acute expansion of the swelling and subsequently, the patient developed ipsilateral facial nerve palsy. Examination showed right preauricular swelling measuring about 6 x 6 cm that extended posteriorly until the mastoid region, superiorly until the zygoma, and inferiorly until the angle of the mandible, pushing the ear lobule anteromedially. There was bluish discoloration of the overlying skin. The swelling was warm and tender on palpation. Multiple shotty lymph nodes were palpable at the posterior triangle. Aspiration of the swelling revealed blood content, but it reaccumulated after a few hours. A magnetic resonance imaging (MRI) of the neck showed a lesion confined within the parotid gland. There was a presence of air-fluid level with dependent layers of hyperintense on the T1-weighted image (T1WI) and T2-weighted image (T2WI) with clumps of isointensity on T1WI, which are hypointense on T2WI, which is suggestive of acute-late subacute blood product. A diagnosis of lymphatic malformation complicated with hemorrhage was made. Hence, the patient underwent surgery for the evacuation of blood clot and right superficial parotidectomy. Histopathological examination of the intraoperative tissue biopsy revealed evidence of venolymphatic malformation of the parotid gland. Postoperatively, he was discharged home after three days. The facial nerve function recovered from House and Brackmann grade II to grade I three weeks after the surgery.

Vascular malformations (VMs) are a rare clinical entity and even rarer are those originating from the salivary glands. Those arising from the parotid gland are the most reported with the most common subtype being venous or arteriovenous malformation. Here, we report a case of a neck mass which was identified as a venolymphatic VM in the parotid gland. A 14-year-old patient presented with a progressive right-sided facial mass without constitutional symptoms. Ultrasonography of the mass showed a well-defined lobulated parotid mass with few cystic areas and minimal vascularity, thus deducing a differential of either a branchial cyst or a pleomorphic adenoma. Excision of the mass was performed and sent for histopathological diagnosis. The grossly hemorrhagic and congested specimen showed many vascular channels lined by flat endothelium on microscopy. These dilated channels of varying sizes had many red blood cells and proteinaceous fluid. The lesion was also seen infiltrating the normal surrounding structures of the salivary gland tissue. With the rare incidence of VMs occurring anywhere in the body, diagnosing a venolymphatic malformation occurring in the parotid gland was an out of common experience. Better imaging of a mass in the salivary gland using not only ultrasonography but also color Doppler and magnetic resonance imaging can help rule out the rare entities that can sometimes be overlooked and help plan better treatment for the patient.
