Perforating folliculitis is a skin condition in humans characterized by discrete follicular keratotic eruptions involving mainly the hairy parts of the extremities.[1]: 539–540
Signs and symptoms
Primary lesions of perforating folliculitis typically have scaly, folliculocentric papules that are 2 to 8 mm in diameter, tiny central keratotic plugs, and various degrees of erythema.[2]
Causes
Even though there have been some documented occurrences of idiopathic perforating folliculitis, certain correlations have also been noted. The more prevalent relationship with
Diagnosis
In cases of perforating folliculitis, the affected hair follicle has a transepithelial channel and, frequently, a parakeratotic luminal plug as well as focal destruction of its lateral wall. In this transfollicular channel and in the follicular lumen, parakeratotic keratin is combined with connective-tissue components, such as collagen and elastin, and a variety of inflammatory cells. A hair shaft or hair fragment may occasionally be seen inside the transfollicular channel, the follicular lumen, or both. Usually, there is localized fibrosis and scant inflammation in the dermis around the follicle.[2]
Treatment
Tretinoin 0.1% cream can be used to treat perforating folliculitis.[2]
