Basal Cell Adenoma
Basal cell adenoma is a benign neoplasm which accounts for approximately 2% of salivary gland tumors and most commonly occurs in major salivary glands (parotid gland superficial lobe, 70% of cases). It occurs in 4th to 9th decades of life, and there is no sex predisposition. Patients usually present with a painless slow growing, mobile mass. Grossly they are solid, encapsulated and sharply demarcated from the surrounding salivary gland parenchyma.
This superficial parotidectomy specimen is from a 62 y/o male who presented with a nontender, mobile swelling in front of right ear. The cut surface shows a well-circumscribed encapsulated round tumor measuring 1.8 cm in diameter. Microscopic examination was diagnostic of basal cell adenoma.
