The aim was to perform a retrospective audit of rare vascular neoplasm - Carotid body tumor (CBT) in our cancer center.
Materials and Methods
An institutional retrospective audit was performed in Curie Manavata Cancer Centre, Nasik, India from 30th June 2013 to 30th June 2014. Total of 5 patients were diagnosed with CBT in a period of 6 months.
Out of 5 patients who were diagnosed with CBT, 2 (40%) were males and 3 (60%) were females with a ratio of 1:1.5. The types of CBT were familial in 2 patients (40%), sporadic in 2 patients (40%) and hyperplastic in 1 patient (20%). The clinical presentation of the 5 cases was, 3 patients (60%) had a painless, progressive swelling, 2 patients (40%) had pre-auricular pain, and 1 patient (20%) was identified in routine follow-up. All patients underwent surgical excision of CBT with no need to pre-operative embolization. 40% of patients had cranial nerve injury and hematoma formation. 1 out of 5 patients received post-operative adjuvant radiotherapy due to large tumor size and lymphatic spread. No recurrence was found after a follow-up of 6 months.
Surgical management of CBT remains a challenge for head and neck surgeon. Despite a reduction in stroke and mortality, there can be a significant morbidity associated inadvertent adjacent cranial nerve injuries. However, our audit shows these tumors can be managed well with meticulous planning and execution of the surgery.
