Elastofibroma developing at the subscapular port site after thoracoscopic surgery: first case report

In recent years, the number of cancer patients who undergo endoscopic surgery has been increasing, and port-site recurrence is becoming a more common complication. A 66-year-old woman underwent thoracoscopic left lower lobectomy with lymph node dissection for pT1aN0M0 adenocarcinoma of the lung. Six years after surgery, CT revealed a subscapular tumor measuring 3 cm at the site of the surgical port wound. Although port-site cancer recurrence was suspected, needle biopsy revealed that the tumor was an elastofibroma. During 6 months of follow-up, MRI revealed no further change, and it was concluded that development of the tumor at the subscapular port site had been merely coincidental.
