Summary
A rare hair growth disorder, nevoid hypertrichosis, presented in a 3-year-old girl with patchy, excessive hair growth. Histology confirmed the diagnosis, highlighting this rare condition with segmental hair distribution.
Area of Science:
- Dermatology
- Medical Genetics
Background:
- Nevoid hypertrichosis is a rare congenital hair growth disorder.
- It typically manifests as localized patches of excessive hair growth, often present at birth or shortly after.
- The condition is characterized by a segmental distribution pattern.
Observation:
- A 3-year-old girl presented with distinct patches of hypertrichosis on her scalp, extremities, and lumbosacral region.
- The abnormal hair growth occurred on normally pigmented skin.
- No significant family history or extracutaneous abnormalities were identified.
Findings:
- Clinical diagnosis of patchy nevoid hypertrichosis was confirmed through histological examination.
- The case presented as a solitary developmental defect with multiple affected areas.
- This presentation is considered rare in the existing literature.
Implications:
- This case expands the understanding of nevoid hypertrichosis presentations.
- Highlights the importance of histological confirmation for rare dermatological conditions.
- Contributes to the literature on solitary developmental defects with nevoid hypertrichosis.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
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...
01:49Meiosis I
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...
01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
