Systemic mastocytosis is a neoplastic proliferation of mast cells that most frequently involves cutaneous sites. Mastocytosis involves various extracutaneous sites, but the lymph node is rare. We present an interesting image of systemic mastocytosis in the lymph node with marked eosinophilia. It is a rare subtype of systemic mastocytosis requiring high suspicion levels for the correct diagnosis.
