WHAT CAUSES RECURRENT CELLULITIS?
In a patient with recurrent cellulitis of the thigh, can the punctum of a follicular cyst in the buttock serve as a portal of entry for the causative bacteria? There appears to be no other identifiable cause.

An inflamed, infected cyst can be the source of cellulitis, particularly on the face. The punctum does not necessarily need to be the portal of entry. Any other area of trauma or superinfection could result in cellulitis. It is also important to assess for other predisposing factors, including diabetes or immunodeficiency.
