Summary
Primary hypertrichosis, a rare condition causing excessive hair growth in children, can be generalized or localized. While often benign, it may cause cosmetic and psychosocial distress, necessitating discussion of hair removal options.
Area of Science:
- Pediatric Dermatology
- Genetics and Rare Diseases
- Dermatology
Background:
- Primary hypertrichosis is a rare condition characterized by excessive hair growth.
- It can manifest in generalized or localized symmetrical forms in children.
- The exact etiology of primary hypertrichosis remains largely unknown.
Purpose of the Study:
- To review the causes, presentation, and therapy of primary generalized and localized symmetrical hypertrichosis in children.
- To understand the clinical characteristics and management of pediatric hypertrichosis.
Main Methods:
- A retrospective medical record review was conducted.
- The study included a case series of 11 prepubertal patients with idiopathic hypertrichosis.
- Data collected included clinical distribution of hair growth and hair removal methods.
Main Results:
- Eleven patients (7 girls, 4 boys) aged 4 months to 11 years were evaluated.
- Four patients had generalized hypertrichosis, and 7 had localized symmetrical hypertrichosis (e.g., hypertrichosis cubiti, anterior/posterior cervical hypertrichosis, faun tail deformity).
- Onset for generalized hypertrichosis was at birth; localized forms appeared from birth to 4 years. One patient had associated gingival hyperplasia, and another had spinal abnormalities.
Conclusions:
- Primary hypertrichosis in children, both generalized and localized, is rare and of unknown origin.
- Despite being generally benign, it can lead to significant cosmetic disfigurement and psychosocial impact.
- Adequate counseling on temporary and permanent hair removal options is crucial for affected patients and families.

01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
