Parotid gland pleomorphic adenoma with floret-like tyrosine-rich crystals.

mass showing “cellular components with mucoid material consistent with pleomorphic adenoma.” The gland was removed, revealing a 2.9 x 2.4 x 2.0 cm well circumscribed tan-grey opaque mass with a myxoid appearance on cut surface (Figure 1). The frozen section slides demonstrated mixed epithelial and myxoid areas. The extensive myxoid stroma contained characteristic red to pink crystalloid deposits arranged in floret-like patterns (Figure 2). The intraoperative consult diagnosis was “myxoid lesion suggestive of mixed tumor on representative section.”
