Coin Lesion of Lung
What is it?
Coin lesion (also called solitary pulmonary nodule) is a small, round lesion located in the lung, seen on a chest X-ray or chest CT. In the vast majority of cases, this finding does not cause symptoms, and is detected by chance during an imaging test done for another purpose. In most cases, coin lesion is a benign finding that can actually be found in a large portion of the population. However, in some cases, this finding can be cancerous - It could be a tumor of early-stage lung cancer, or a metastasis of cancer from another organ that has spread to the lung. Risk factors for malignancy in this case are old age, smoking, personal or family history of malignancy or occupational exposure to hazardous substances (such as asbestos).

Signs & symptoms
A solitary pulmonary nodule is almost always an incidental finding that does not cause symptoms. Signs that may be related to malignancy, and which the doctor will look for in a physical examination, are for example significant weight loss or enlargement of lymph nodes.
Diagnosis
The investigation of a solitary pulmonary nodule is intended to distinguish between benignity and malignancy of the lesion. The first step your doctor will take is to compare the imaging in which the lesion appears and previous imaging, if any, in order to detect a change in size, shape and growth rate. The next steps in the investigation depend on the degree of suspicion of your doctor that the finding is malignant. In case of low suspicion, frequent imaging follow-up may be sufficient. In case of high suspicion, further tests will be needed and will include a biopsy of the lesion (taking a sample of tissue from the lesion) or a surgery to remove it.
Treatment
A solitary pulmonary nodule that has been found to be benign does not require treatment. A lung lesion that has been found to be cancerous requires oncological treatment, which includes surgery and/or medication.
