Perforating folliculitis in a patient with cystic fibrosis

We report a case of a young man with perforating folliculitis and cystic fibrosis with complications including chronic obstructive pulmonary disease, insulin dependent diabetes mellitus, and liver cirrhosis. We demonstrate increased TGF-β1 immunohistochemical staining in the perforating folliculitis lesions of our patient and discuss the possible associations between cystic fibrosis and perforating folliculitis.
