Potato nodes

Last revised by Dr Daniel J Bell on 05 May 2019

Potato nodes are a classical moniker for the large nodes seen in the lung hila and mediastinum on the chest radiograph in pulmonary sarcoidosis. This name is derived from the characteristic bulky irregular morphology of the nodes which is reminiscent of large lumpy potatoes. Although this appearance is an Aunt Minnie, it is unlikely to be pathognomonic, but in the right clinical context it is unlikely to be anything else.

A reference for the first use of this rather apt term remains elusive.
