Signs and symptoms

The majority of patients describe a quick onset of extensive pruritic papular eruption. It has been noted that hot showers aggravate disseminate and recurrent infundibular folliculitis, while cool showers, creams, and swimming can alleviate it.

Causes

It is unknown what causes disseminate and recurrent infundibular folliculitis. A hot, muggy atmosphere is frequently mentioned in the history as a precipitating factor. Once it has started, widespread and recurrent infundibular folliculitis usually lasts for a long time before ceasing to exist.

Diagnosis

A non-specific histologic examination reveals superficial spongiotic dermatitis connected to a hair follicle and the surrounding epidermis. A mention of exocytosis is made in the spongiotic region. Inflammatory cells are present in the subadjacent dermis, while the deeper dermis is unaffected.

Treatment

Reducing activity in hot, humid environments may be required to stop or lessen the symptoms of disseminate and recurrent infundibular folliculitis. For thirty years, cooling, soothing emollients have been used to treat disseminate and recurrent infundibular folliculitis, with varying degrees of efficacy.
