Squamous Cell Carcinoma of the Lung in McCune-Albright Syndrome.

McCune Albright Syndrome (MAS) is caused by a mutation in the GNAS gene that results in multiple endocrinopathies such as Cushing syndrome, acromegaly, hyperthyroidism, and precocious puberty. Despite the presence of pleiotropy coupled with a GNAS gene mutation, malignancy is a rare occurrence in MAS. There is minimal literature showcasing squamous cell carcinoma (SCC) of the lung in patients with MAS.
