+The sections show a large cystic structure filled with bland hyaline material that is lined by a squamoid epithelium. Focally, a smaller, microscopic, cyst has respiratory epithelium with cilia.  Surrounding the cysts are normal fibro-adipose tissue, fragments of skeletal muscle, normal thyroid tissue and sebaceous glands.  There is focal granulomatous inflammation associated with the wall of the large cyst.  There is normal bone with unremarkable bone marrow, that has all three main lineages and scant adipose tissue.  One small benign lymph node is present.
