Vascular Transformation of Bilateral Cervical Lymph Node Sinuses: A Rare Entity Masquerading as Tumor Recurrence

Vascular transformation of sinuses (VTS) is a rare and reactive vasoproliferative disorder infrequently affecting the cervical lymph nodes. It is characterized by effacement of nodal architecture by variable expansion of the subcapsular, intermediate, and medullary sinuses. We report a very rare and unique case of VTS in bilateral cervical lymph nodes along with angiolipomatous hamartoma in a postoperative patient of squamous cell carcinoma of buccal mucosa clinically masquerading as tumor recurrence. To the best of our knowledge, only 15 cases of VTS have been reported in cervical lymph nodes till date and associated angiolipomatous or angiomyomatous hamartoma-like area was noted only in two cases of cervical lymph node VTS. © 2014, The Association of Oral and Maxillofacial Surgeons of India.
