Monilethrix is a rare genodermatosis characterized by a hair shaft dysplasia responsible for hypotrichosis. We report the case of a child with monilethrix with no associated cases in the family. Trichoscopy facilitated the diagnosis. A 2-year-old boy presented with diffuse alopecia and persistent fragile hair for several months. Clinical examination revealed alopecia with hairs broken several millimeters from the scalp. Trichoscopy revealed zones of dystrophic constriction of the hair shaft, separated at regular intervals by elliptical nodes of normal thickness, giving a "necklace" appearance...

Circle hairs (CHs) represent a body hair growth disorder which is characterized by asymptomatic presence of hairs in typical circular or spiraliform arrangement. It is not associated with follicular or inflammatory abnormalities. CHs are rarely reported, probably underestimated, as medical consultation for CH only is rare in practice. It needs to be differentiated from rolled hairs, which is a relatively common disorder of hair growth associated with follicular hyperkeratosis and keratin plugging. Trichoscopy is a noninvasive technique to confirm the diagnosis without biopsy...

Background: Cosmetic deformities can result from various types of alopecia or even post hair transplantation procedures. Patients with such deformities seek aesthetically appealing longer-lasting options. Scalp concealers are commonly used by men and women to camouflage these deformities. Scalp micropigmentation (SMP) is one of the concealers recently gaining popularity. Objectives: SMP is a novel technique wherein microdot tattoos are placed in a stippling pattern to mimic hair follicles that are cut close to the scalp and various variables affecting its outcome were evaluated...

Trichoscopy has become an essential tool for the diagnosis of various diseases that affect the hair and scalp. Through dermatoscopy we identified a set of findings that share a circular shape of hair shafts. The objective of this study is to distinguish among the various forms of circular hairs in order to identify their peculiarities and to describe in which skin disorders they can be found.

Dermoscopic features of discoid lupus erythematosus (DLE) depend on the stage of the lesions: active lesions include yellow-brown dots and red dots, whereas longstanding inactive lesions show absence of follicular openings, cicatricial milky red or white patches, structureless white and brown areas, and thick arborizing vessels. Loss of pinpoint white dots, blue-gray dots in a speckled pattern, and a peripheral pigmented network have been described on dermoscopy of DLE in dark skin. We report a blue-white veil as a novel dermoscopic feature in 2 cases of biopsy-proven DLE in African-American patients...

Intralesional corticosteroid (IL-CS) injections have been used to treat a variety of dermatological and nondermatological diseases. Although an important therapeutic tool in dermatology, a number of local side effects, including skin atrophy, have been reported following IL-CS injections. We recently noticed that a subset of patients with steroid-induced atrophy presented with ivory-colored areas under trichoscopy. We performed a retrospective analysis of trichoscopic images and medical records from patients presenting ivory-colored areas associated with atrophic scalp lesions...

Yellow dots are follicular ostium filled with keratin and/or sebum. Initially, they were exclusively associated with alopecia areata. Currently they have also been described in androgenetic alopecia, chronic cutaneous (discoid) lupus erythematosus, and dissecting cellulitis. Due to the growing importance of trichoscopy and its findings in the evaluation of the scalp, this article describes the main diseases in which yellow dots are a common trichoscopic finding, highlighting its characteristics in each dermatosis...

Pseudopelade of Brocq (PPB) is a rare, chronic, slowly progressive cicatricial alopecia that generally affects middle-aged women. Vertex and parietal scalp are commonly involved. It can be primary or secondary to end stage of other scarring alopecia such as lichen planopilaris and discoid lupus erythematosus. It is diagnosed by exclusion both clinically and trichoscopy. There is no standard treatment for PPB. We hereby report a case of rapidly progressing primary idiopathic pseudopelade of Brocq in a young female child confirmed by trichoscopy and histopathology...

BACKGROUND: Scalp involvement is not directly evaluated in patients with dermatomyositis (DM). Therefore, the exact frequency of scalp dermatomyositis (SDM) and its clinical and trichoscopic characteristics have been poorly described. OBJECTIVE: The aim of this study was to determine the frequency and clinical and dermoscopic features of SDM in patients diagnosed with DM. METHODS: We performed a descriptive prospective, cross-sectional observational study that included all patients diagnosed with DM at a Mexican academic institute over the course of a year...

BACKGROUND: Scalp is a common location of autoimmune bullous diseases. Trichoscopy is a noninvasive method for diagnosing hair and scalp diseases. Data on trichoscopy in autoimmune bullous diseases are limited to the studies on pemphigus including a small number of patients. Trichoscopic characteristics of bullous pemphigoid and dermatitis herpetiformis were not reported to date. The aim of the study was to determine the value of trichoscopy in the differential diagnosis of pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, and dermatitis herpetiformis...

Trichoscopy is a noninvasive visualization tool used to more accurately diagnose hair and scalp disorders. Alopecia areata (AA) in the patient of African descent can mimic the early signs of central centrifugal cicatricial alopecia (CCCA), especially if the initial presentation of hair loss occurs on the central scalp. Two African-American women presented with singular round-ovoid patches of decreased hair loss on the central scalp. Given the clinical presentation, CCCA was the working diagnosis. However, using dermoscopy, the patients were found to have exclamation hairs and short broken hairs on a background of honeycomb-like pigmented network and regular pinpoint white dots consistent with AA...

Tinea capitis is the most common pediatric superficial dermatophyte infection. The causative species vary, as for instance, Microsporum canis predominates in Europe, while Trichophyton tonsurans predominates in North America. Tinea capitis does not respond well to topical therapy alone, thus oral therapy is requisite. The drug of choice is griseofulvin; however in some countries, it is no longer available. Fungal culture should be requested in the persistent, scalp lesion and trichoscopy can put forward a speedy diagnosis by its characteristic findings...

Hair loss or alopecia is a common and distressing clinical complaint in the primary care setting and can arise from heterogeneous etiologies. In the pediatric population, hair loss often presents with patterns that are different from that of their adult counterparts. Given the psychosocial complications that may arise from pediatric alopecia, prompt diagnosis and management is particularly important. Common causes of alopecia in children and adolescents include alopecia areata, tinea capitis, androgenetic alopecia, traction alopecia, trichotillomania, hair cycle disturbances, and congenital alopecia conditions...

Squamous cell carcinoma (SCC) is the second most cutaneous malignancy after basal cell carcinoma (BCC) with increasing incidence. In the view its nodular manifestation; it can appear similar to nodular BCC, atypical fibroxanthoma, sclerosing liposarcoma and desmoplastic melanoma. Prognostic and therapeutic implications are different in all these conditions and thus their distinction becomes important. Trichoscopy is a simple and non-invasive technique to visualize certain morphological features of skin lesions and it improves the diagnostic accuracy for melanocytic and nonmelanocytic pigmented lesions...
