Abstract:
The case of a patient with systemic lupus erythematosus presenting with severe leg cellulitis caused by Hemophilus influenzae non-B biotype III is reported. Skin infections caused by H. influenzae in general, and of the extremities in particular, seem to be rare in adults. This is the first reported case of cellulitis caused by H. influenzae biotype III. The infection was treated successfully with antibiotics. This case highlights the importance of blood cultures and prompt antimicrobial treatment in febrile adults with cellulitis, especially immunocompromised patients.
