[Adrenal epithelial cyst of embryonal vestiges]. / Quiste epitelial suprarrenal de restos embrionarios.

A 10 x 6.5 cm cyst with ciliated cell lining was removed from a 43-year-old woman. The immunohistochemical studies demonstrated that the cyst cells expressed keratins (Lu 5+) and the adrenal cortical cells did not, suggesting that the cyst lining was not derived from adrenal cells. The presence of ciliated cells indicates that the cyst was derived from embryonal vestiges.
