EC Clinical and Medical Case Reports

Introduction: This paper reports on an elderly African female who presented with a right intrathoracic space-occupying lesion, which was subsequently discovered to be a giant benign solitary fibrous tumor of the pleura—with a discussion of the surgical intervention that followed.

Case Report: Presented is the case of a 75-year-old female, who was referred to the Cardiovascular and Thoracic Surgery Unit, Federal Medical Center, Umuahia, Nigeria, with complaints of vague chest discomfort and progressive shortness of breath over 18 months. The imaging investigations were reviewed, indicating the need for a right posterolateral thoracotomy for tumor resection. The surgical procedure lasted approximately 2 hours, followed by an uneventful postoperative recovery. After one week, the patient was discharged, is currently asymptomatic, and is being seen on an outpatient basis.

Discussion: Pleural SFTs are rare neoplasms, most benign. Pleural SFTs present with various and distinct symptoms. Chest CT scanning is the preferred imaging technique. Nevertheless, the radiological differentiation between the benign and malignant variants remains challenging. Surgery is the treatment of choice for a solitary fibrous tumor of the pleura (SFTP). Local recurrence can present in malignant cases but is infrequent in solitary benign tumors. Surgical resection's prognosis is generally favorable, even for a malignant SFTP.

Conclusion: Rapid preoperative diagnosis followed by expeditious surgical intervention is the goal in the surgical resection of a solitary fibrous tumor (SFT), resulting in rapid symptomatic relief and long-term survival in benign and most malignant SFTs. SFTs are rare tumors, challenging to diagnose definitively.
