Multiple myeloma presenting with Hemophilus influenzae septic arthritis: case report and review of the literature.

This article reports a case of pyogenic arthritis with Hemophilus influenzae in a previously healthy woman. This infection was the initial manifestation of an underlying serious systemic illness, multiple myeloma. Certain laboratory parameters as well as the causative organism suggested the underlying disease. Although infections are common in patients with known multiple myeloma, certain infections can provide a hint to concomitant serious systemic diseases and thus facilitate their early diagnosis.
