If a solitary fibrous tumor becomes large, which symptoms may occur?

• A. Dyspnea, cough, chest heaviness
• B. Fever and night sweats
• C. Weight loss and malaise
• D. Hemoptysis

Answer: (A)

When a solitary fibrous tumor in the thoracic cavity grows large, it typically causes symptoms from mass effect on nearby structures rather than systemic illness. The enlarging tumor presses on the lung and airways, which limits lung expansion and irritates the pleura, leading to shortness of breath (dyspnea) and a nonproductive cough. The sense of chest heaviness comes from the physical presence of a bulky mass occupying space in the chest. Systemic symptoms like fever, night sweats, weight loss, and malaise are not the usual presentation for a solitary fibrous tumor unless there’s another process involved, such as infection or advanced disease. Hemoptysis can occur if there is vascular involvement or necrosis, but it is less typical for a large pleural solitary fibrous tumor than the compressive respiratory symptoms described above.
