An 80-year-old male underwent chest computed tomography (CT) due to complaints of right-sided chest pain. A chest wall tumor was identified in the right eighth intercostal space, corresponding to the location of his pain. The patient was subsequently referred to our department for further evaluation and treatment. Utilizing single-port thoracoscopic surgery, the tumor was successfully excised. Intraoperatively, the tumor was found beneath the parietal pleura, was contiguous with to the intercostal nerve. Histopathological analysis confirmed the diagnosis of schwannoma originating from the intercostal nerve. The right-sided chest pain was reduced after operation significantly. No recurrence or relapse of symptoms was observed during follow-up. Although schwannoma of the chest wall in asymptomatic in many cases, in this case, localized pain corresponding to the tumor site was evident. This emphasizes the importance of considering schwannoma in the differential diagnosis of chest pain.
