History: This image is from a fine needle aspiration biopsy of a lymph node in a patient with lymphadenopathy, joint symptoms, and elevated ACE.
What is your diagnosis?
Answer: Well-formed granuloma characteristic of sarcoidosis.
Comment: This air-dried smear demonstrates well-formed granulomata. The histiocyte nuclei are elongated with a shape reminiscent of a footprint. Their arrangement in granulomata have been described as being like a “dance step diagram”.
