Introduction: Wound seeding during surgical excision of malignant tumor is known problem in the oncologic surgery. Trocar site recurrence (TSR) is well described in laparoscopic oncologic surgery. Little has been reported about TSR after robotic partial nephrectomy (RPN) performed for renal cell carcinoma (RCC). Here, we report on the incidence of TSR and demonstrate the presentation of this type of RCC recurrence. Patients and Methods: We reviewed prospectively collected data about patient who underwent RPN at our institute from September 2009 to March 2018. We reviewed the medical record of the patients who had the diagnosis of RCC on the final pathology. We identified the patient with TSR and demonstrated their presentation and treatment along with the outcome. Results: A total of 335 patients underwent RPN during the study period for renal mass. Two hundred and sixty-nine (80.3%) patients were found to have RCC on the final pathologic evaluation of their mass. We identified two patients (0.7% of all the RCC in the study) who developed TSR during an average follow-up period of 31 months (ranging from 18 to 72 months). The first recurrence appeared 18 months after the surgery. The second recurrence presented 72 months after RPN. Both cases underwent open surgical excision of the trocar site, in which the recurrence appeared. Conclusion: TSR is potential type of RCC recurrence after RPN, though it is rare and underreported. Special attention should be given to examine the trocar site during the surveillance follow-up of RCC treated with RPN. It can develop up to 72 months after the surgery.
