Primary sternal osteomyelitis (PSO) is a rare condition defined as an infection of the sternal bone marrow with no contiguous source of infection. The overlap in symptoms of PSO with other cutaneous and malignant pathologies often leads to misdiagnosis and delay of appropriate care. In this case report, we outline the presentation of PSO in a 30 year-old male patient who was newly diagnosed with type 2 diabetes mellitus. The patient was successfully treated with antibiotic therapy alone, without need for surgical intervention. Interestingly, the patient's workup returned with negative microbial cultures. To our knowledge, this patient represents the first reported case of a spontaneously presenting, culture-negative PSO.
