Hair and Nail Conditions: Hypertrichosis and Hirsutism.

Hypertrichosis and hirsutism can be signs of underlying conditions, some of which may be life-threatening. They also can result in significant psychosocial distress for patients. Hypertrichosis refers to excessive hair growth beyond normal variation for a patient's age, sex, or race or for a particular body area. Hirsutism refers to an abnormal excess of hair growth solely in androgen-dependent areas of the body in females. The standard for hirsutism assessment is the modified Ferriman-Gallwey (mFG) score. Hirsutism can be idiopathic or associated with endocrine conditions, most commonly polycystic ovary syndrome (PCOS). Evaluation for underlying causes may be indicated depending on the clinical presentation. For premenopausal patients with an abnormal hirsutism score (ie, mFG score of 8 or greater), a serum total testosterone level should be obtained. If the level is normal in patients with moderate to severe hirsutism and/or evidence of a hyperandrogenic endocrine condition, an early morning serum total testosterone level and a free testosterone level should be obtained. An elevated total testosterone level indicates a hyperandrogenic state, and further testing is needed to determine if this is due to PCOS or another endocrine condition. Hair removal options for patients with hirsutism include temporary methods, electrolysis, and laser treatments. Pharmacotherapies include topical creams, combination oral contraceptives, and antiandrogens. Referral to an endocrinologist may be indicated if an underlying endocrine condition is suspected.

Care of Congenital Melanocytic Nevi in Newborns and Infants: Review and Management Recommendations.

A pediatric dermatology expert working group performed a narrative review to describe care related to congenital melanocytic nevi (CMN) in neonates and infants. There are no published guidelines for most aspects of care, including routine skin care and visit intervals. Few guidelines exist for surgical management; newer recommendations favor conservative practice. Emerging evidence contributes to recommendations for screening MRI to evaluate for neural melanosis and related central nervous system complications, however, more research is needed. Risk for melanoma is generally low, but those with large, giant, or multiple CMN have a higher risk. Multidisciplinary care, with a focus on family and patient preferences, is of paramount importance. Without standardized screening and management guidelines, questions abound regarding appropriate physical examination intervals, potential treatment including full or partial excision, timing and frequency of imaging, melanoma risk, and assessment for neural melanosis. This review highlights the current state of knowledge concerning care of patients with CMN, reveals gaps in the literature surrounding skin care, and provides management recommendations. We additionally discuss cutaneous complications of CMN, such as pruritus, hypertrichosis, and wound healing. Resources and references for families and providers can help patients navigate this sometimes challenging diagnosis. Finally, we contribute expert care recommendations to the current body of literature as a foundation for the development of future, more comprehensive care guidelines.

Approach to inherited hypertrichosis: A brief review.

Hypertrichosis refers to the growth of hair, of an excessive amount and thickness, on any part of the body. It must be distinguished from hirsutism which is characterized by excess growth of hair in androgen-dependent areas on the upper lip, chin, chest, linea alba, thigh and axilla. Hypertrichosis may be localized or generalized, and congenital or acquired. Excess hair growth has a psychological impact on the child as well as the parents due to the cosmetic disfigurement it produces. Current treatment options are limited and not wholly satisfactory. Treatment should be customized according to the area, nature and amount of hair growth, age of the patient and personal preferences. In addition, when hypertrichosis occurs as a component of a syndrome, multidisciplinary management is required to address the associated systemic features. A detailed review of inherited generalized hypertrichosis is presented here with emphasis on clinical clues to identifying complex syndromes with multisystem involvement.

Intense pulsed light treatment for Becker's nevus.

BACKGROUND: Becker's Nevus (BN) is a benign hamartoma with an esthetically troublesome condition secondary to hyperpigmentation and hypertrichosis. Many treatment modalities have been utilized with variable outcomes. OBJECTIVES: To evaluate the efficacy and safety of intense pulsed light (IPL) in the treatment of BN. PATIENTS AND METHODS: IPL was used at filter of 590 nm, fluence of 18-22 J/cm2, double-pulse mode (pulse width of 3-10 ms, pulse delay of 20-30 ms) at 3-month intervals. Final evaluations were performed by physician global assessment and patient satisfaction. Side effects were monitored at each treatment session and follow-up visit. RESULTS: Twenty-four patients (9 females, 15 males) with BN (16 hypertrichotic, 8 atrichotic) completed the study. The mean number of treatment sessions was 5 ± 2.17. The improvement in atrichotic BN group (4.87 ± 0.35) was significantly greater than that observed in hypertrichotic BN group (3.63 ± 0.89) (p = .001). Hair density simultaneously decreased with treatment in hypertrichotic BN. The mean satisfaction score was 5.75 ± 2.05 and 8 ± 0.93 in hypertrichotic and atrichotic BN groups respectively (p = .002). No repigmentation was noted during the follow-up period. No permanent side effects were observed. CONCLUSIONS: IPL is an effective and well-tolerated treatment option for patients with hypertrichotic and atrichotic BN.

Excess hair, hair removal methods, and barriers to care in gender minority patients: A survey study.

BACKGROUND: In gender minority patients, electrolysis and laser hair removal may be necessary to reduce facial and body hair in individuals seeking a more feminine appearance and/or modified gender expression. These procedures may also be required preoperatively for some gender-affirming surgeries. AIMS: To identify (a) the frequency of unwanted facial and body hair, (b) the use of various hair removal methods, and (c) associated barriers to care in gender minority patients. METHODS: An online-based patient survey was distributed via social media on Facebook® , YouTube® , and Instagram® in fall 2018. Respondents were at least 18 years old and self-identified as a gender minority. RESULTS: In total, 991 responses were recorded with a completion rate of 77%. Considering excess hair, 84% of transwomen on feminizing hormone therapy (FHT: estrogen and anti-androgen therapy), 100% of transwomen not on FHT, and 100% of nonbinary individuals on FHT reported excess facial/body hair. Laser hair removal (18%) and electrolysis (17%) had similar rates of use in this cohort and were more commonly reported for nonsurgical gender-affirming purposes than preoperative preparation. Cost was the most frequently cited barrier to care. CONCLUSION: As the majority of transwomen and nonbinary people on feminizing hormone therapy had persistent excess facial/body hair, routine use of gender-affirming hormones is not sufficient to fully eliminate unwanted hair. There remains a critical need to advocate for more comprehensive insurance coverage for laser hair removal and electrolysis in gender minority patients.

A cut above the rest: Trimming as a painless depilatory.

Shaving and other modes of epilation can cause undue anxiety, pain, or skin irritation in children. Here, we present hair trimming as a safe, painless, and cost-effective alternative for patients with unwanted hair which may be performed indefinitely or until the child is old enough to direct management. In select cases, removing unwanted hair using this technique may facilitate dermatologic surveillance.

Hair disorders in cancer survivors.

With increasing survival rates across all cancers, survivors represent a growing population that is frequently affected by persistent or permanent hair growth disorders as a result of systemic therapies, radiotherapy, surgical procedures, and therapeutic transplants. These hair disorders include persistent chemotherapy-induced alopecia, persistent radiotherapy-induced alopecia, endocrine therapy-induced alopecia and hirsutism, postsurgery alopecia and localized hypertrichosis, and persistent stem cell transplantation and targeted therapy-induced alopecia. The information contained in this continuing medical education series should facilitate a better understanding on hair disorders in cancer survivors so that adequate support and therapies may be provided.

Acquired Localized Hypertrichosis Following Pressure Garment and/or Silicone Therapy in Burn Patients.

Hypertrichosis is characterized by excessive and abnormal hair growth anywhere on the skin and may develop after prolonged local irritation, such as application of a cast, injury, or a bite. Pressure garment/silicone therapy is often used to prevent hypertrophic scar formation. The adverse effects of gel sheet application include rash, skin breakdown, cessation of scar responsiveness, pruritus, contact dermatitis, and dry skin. We report on 7 burn patients who developed hypertrichosis following application of pressure garment/silicone therapy to prevent hypertrophic scarring.

Hair manifestations of endocrine diseases: A brief review.

Hair disorders are common in clinical practice and depending upon social and ethnic norms, it can cause significant psychosocial distress. Hair growth, cycling and density are regulated by many endogenous factors, mainly circulating hormones. Thus, diseases affecting the endocrine system can cause varied changes in physiological hair growth and cycling. Diagnosis and treatment of these disorders require a multidisciplinary approach involving a dermatologist, gynecologist and an endocrinologist. In this review, we briefly discuss the influence of hormones on the hair cycle and hair changes in various endocrine disorders.

Localized hypertrichosis of intermammary cleft in monozygotic twins.

Hypertrichosis is a condition in which hair is longer and denser than what is considered normal for an individual based on age, sex, ethnicity, and location on the body and can be classified based on its distribution (generalized vs localized), age of onset (congenital vs acquired), and type of hair (lanugo or vellus vs terminal). We describe a rare case of monozygotic female twins who presented for localized hypertrichosis of the intermammary cleft that developed during puberty. Endocrine examination was unremarkable. Discussion of various treatment modalities should be considered, because localized hypertrichosis may have a considerable psychosocial effect.

Hypertrichosis lanuginosa congenita treated with diode laser epilation during infancy.

We report the case of a girl with hypertrichosis lanuginosa congenita treated with diode laser depilation since the age of 9 months. The treatment was well tolerated, and neither general nor local anesthesia was needed. A reduction of approximately 80% of facial and body hair was noted, which improved her condition significantly.

How to diagnose and treat medically women with excessive hair.

Excessive hair growth in women is common and due to a broad spectrum of causes. Management options comprise different pharmaceuticals, epilation methods, and aesthetic approaches. Because excessive hair growth in women may cause psychological and psychosocial problems, a holistic treatment approach, including support and emotional coping strategies, should be recommended. In this article, diagnostic procedures and treatment options for excessive hair growth in female patients are discussed.

Congenital smooth muscle hamartoma on the face treated using vascular laser.

A congenital smooth muscle hamartoma is a rare, benign proliferation of smooth muscle bundles in the dermis that is usually diagnosed in the neonatal period or infancy. Surgical excision is the first-line therapeutic option, but in certain areas such as the face, surgery may be too aggressive, and different treatments should be considered. We present the case of a congenital smooth muscle hamartoma on the face treated using pulsed dye laser with good response.

An overview of unwanted female hair.

Unwanted facial hair (UFH) is an important but often overlooked issue, with over 40% of women experiencing some degree of UFH. In the female population a wide spectrum of unwanted hair concerns is represented - from biologically normal but undesirable to excessive unwanted hair with an underlying pathology. While women may seek to manage unwanted hair across their bodies, UFH is a particular concern, due to its negative impact on perceived femininity. There may not always be a direct correlation between degree of severity diagnosed objectively by the physician and level of concern and impact upon the patient. This review discusses the spectrum of facial hair experience and outlines the clinical approach to unwanted hair management including UFH. It highlights the importance of a treatment regimen which should respond to the causation factors and needs of the individual. This will lead to a holistic treatment approach including evaluation of the implementation of emotional coping strategies and on-going support, lifestyle modifications, pharmacological interventions (to address underlying pathologies) and the use of cosmetic hair removal methods as either a stand-alone or adjunct treatment as appropriate to the individual.
