“…Dermoscopy can be used to confirm the diagnosis. [ 13 ] In our case, we used dermoscopy for visualization of in growing hairs. Curetting the papule and putting the tissue over a white paper and again examining under dermoscope will give the diagnosis.…”

Pseudofolliculitis mainly affects the beard area, but it can occur in any area of hair-bearing skin when traumatic methods like shaving or plucking are used to remove the hair. It can be a simple cosmetic problem or a disturbing medical condition for which the dermatologist must be prepared. It can develop in areas of shaving or depilation and has been seen in the pubic region or the axilla, where it is common to find curly hair that emerges at an acute angle. Here, we are reporting a case of pseudofolliculitis over back, termed as pseudofolliculitis corporis. He used to put a pillow behind the back while driving and the pressure caused the pseudofolliculitis. The diagnosis was confirmed by dermoscopy, which is a simple office procedure. Patient was advised to stop using the pillow and improved with topical adapalene and clindamycin gel for 15 days. This entity has not been described in the literature.

Pseudofolliculitis cutis: a vexing disorder of hair growth

Pseudofolliculitis cutis (PFC) is a troublesome and potentially disfiguring cutaneous disorder characterized by a chronic inflammatory response to ingrown hair. Despite a simple precipitating stimulus, ingrown hair, PFC has a relatively complex aetiology that can involve grooming practices, hair type, genetic predisposition and medication history. Curly hair and a single-nucleotide substitution in the gene encoding keratin 75 may act synergistically to increase the risk for developing this condition. PFC is most common in men of sub-Saharan African lineage, but can occur in men and women of many different ethnicities, particularly in body areas where hair is coarse, abundant and subject to traumatic removal. Treatment options for PFC can be divided into three main categories: modifying hair removal practices, managing symptoms with medication, and long-term hair removal with laser therapy. Laser hair removal is safe and effective in most skin types and has become increasingly popular among dermatologists in the treatment of PFC. However, it is imperative that the laser system and parameters are specifically matched to the patient's skin type.

Tinea capitis, a common public health problem in developing countries, has severe forms such as kerion. However, the underlying mechanisms and standard treatments for persistent cases of tinea capitis or kerion remain controversial. In this work, we investigate the ingrown hairs and corresponding treatment in persistent kerion of children. Children with persistent kerion were enrolled among 312 cases of tinea capitis at the Department of Dermatology, Hangzhou Third People's Hospital from January 2020 to June 2024. The presence of fungal infection was ascertained by direct microscopic examination under calcofluor white staining and routine culture. The structure of the ingrown hairs was observed directly by a dermatoscope, which was subsequently extracted using sterile tools. A total of six cases of persistent kerion among 312 cases of tinea capitis were enrolled. Ingrown hairs were ascertained under dermatoscopy and extracted by minor operation. Except for one patient who continued oral terbinafine, the other five cases were cured by removal alone. Ingrown hairs, induced by fungal infection, may be an aggravating factor of persistent course of tinea capitis. Our study demonstrated that the presence of ingrown hairs could be confirmed through direct dermatoscopy, and patients experienced significant improvement following removal treatment under dermatoscopy.
