Summary
This study identifies acquired hyperpigmented patches in children as frictional melanosis. Recognizing this benign condition can prevent unnecessary biopsies and ease parental concerns.
Area of Science:
- Dermatology
- Pediatrics
Background:
- Acquired hyperpigmented patches overlying spinous processes are documented in adults under various names.
- These include Davener's dermatosis, towel melanosis, and lifa disease.
Purpose of the Study:
- To propose a unified, standardized name for this condition in pediatric patients.
- To increase awareness and recognition of frictional melanosis in children.
Main Methods:
- Case report presentation of pediatric patients with acquired hyperpigmentation.
- Review of existing literature on similar conditions in adults.
Main Results:
- Two cases of acquired hyperpigmented patches were observed in pediatric patients.
- The condition is consistent with previously described adult dermatoses.
Conclusions:
- The term "frictional melanosis" is proposed for this benign pediatric condition.
- Increased recognition may reduce unnecessary biopsies and patient anxiety.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
