  A history of a gradual increase in swelling mass was presented in the sublingual gland of a 72-year-old female. The inadequate cytologic specimens retrospectively contained some clusters of three-dimensional monomorphic and round basaloid cells having hyperchromatic small nuclei and scant cytoplasm, along with a small amount of spherical globules of amorphous material and myxoid stroma, adjacent to few squamous metaplastic tumor nests. We first interpreted it as a pleomorphic adenoma, basal cell adenoma (BCA), or adenoid cystic carcinoma (ACC). A tumor extirpation was performed, and gross examination revealed a non-capsulated and ill-defined tumor lesion, looking grayish to yellowish-white, focally associated with fat invasion. On microscopic examination, the tumor was predominantly composed of a proliferation of small to medium-sized mildly atypical epithelial cells having very rare .. Read More»
