Intrathoracic amyloid lymphadenopathy.

2 patients with intrathoracic lymph node enlargement as their presenting symptom, were found to have amyloid lymphadenopathy. Both also had peripheral involved lymph nodes. The demonstration of amyloid deposits in the peripheral lymph nodes did not suffice to deduce that the intrathoracic nodes were of the same nature. A biopsy of the intrathoracic nodes was needed for final diagnosis. An additional 11 cases of intrathoracic amyloid lymphadenopathy from the literature are reviewed.
