| Abstract: | The case describes a female patient with squamous cell carcinoma of the lung who initially presented with mechanical upper-back and neck pain. She had been successfully treated with spinal manipulation for a similar complaint one year earlier, a factor that decreased the suspicion of pathological process on her second presentation. Serious disease as the cause of back pain must be considered in cases with certain historical factors, or when the patient fails to respond to treatment for mechanical back pain. |
