Lymphocytic hypophysitis with lachrymal, salivary and thyroid gland involvement

We report on hypophysitis associated with a prominent lymphoid infiltration of salivary and lachrymal glands in a 35-year-old woman with a dramatic response to steroids. Four years later, overt Graves' disease developed. To our knowledge, pseudotumoral lymphocytic infiltration of both lachrymal and salivary glands has never been described in association with hypophysitis. Benign lymphocytic hypophysitis may belong to a spectrum that extends from low-grade lymphoid proliferation to autoimmune disease. Such a process may follow a regional tissue distribution including pituitary, thyroid, lachrymal and salivary glands.
