Tracheal carcinoma presenting as a thyroid cyst
A. C. Vitug, R. A. Lopchinsky, S. Sridhar, M. F. Wheeler and J. M. Goldman
A patient was seen with a thyroid cyst. Fine- and core-needle biopsies
revealed no evidence of tumor. A thyroid cyst lined by malignant squamous
cells was found at surgery. Invasive squamous carcinoma was found to arise
in adjacent trachea. The thyroid gland was normal except for inflammatory
changes. Aspiration biopsies of thyroid cysts may be misleading, especially
when hemorrhagic; sclerosis should be performed with caution.
