Sweet syndrome in a patient with osteosarcoma

Neutrophilic dermatosis (Sweet syndrome) is a rare condition characterized by painful indurated cutaneous plaques infiltrated with mature neutrophils and may be accompanied by fever, granulocytosis, arthritis, and conjunctivitis. It is associated with various malignant and preneoplastic states, the most common being leukemia and myeloproliferative disorders. Its association with solid tumors is infrequent. The case described here represents, to our knowledge, the first report of Sweet syndrome in a patient with osteogenic sarcoma, a primary tumor of bone arising from mesenchymal cells.
