Caren Dos Santos Lima, Luciana Rodino Lemes, Daniel Fernandes Melo
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...

BACKGROUND: Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma with haemostatic and tissue repairing effects. Being enriched by various growth factors, PRP has become the focus of attention in numerous fields of medicine. Androgenic alopecia (AGA) is a common chronic hair loss disorder, characterised by progressive hair loss. Despite the therapeutic options available, there is low patient compliance and satisfaction rate...

Courtney M Johnson, Mariya Miteva
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...

Liwen Xu, Kevin X Liu, Maryanne M Senna
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...

Dermoscopy is a method of growing significance in the diagnoses of dermatological pigmented skin diseases. However, in my case, mycology culture was negative and successful treatment was given on the basis of trichoscopy and wood lamp examination. I hereby describe a young boy with tinea capitis, multiple "comma hairs" and "zigzag hair" and a subtle additional feature "Morse code-like hair" when intensification was applied. Dermatoscopic aspects found skin Type 2 in a child of as a distinctive dermoscopic finding...

We present a case of a 17-year-old girl admitted to the Psychiatric Department recovering from a suicide attempt with colchicine. One week after poisoning, a sudden onset of hair loss was observed. Positive hair pull test and trichoscopy demonstrated the presence of anagen hairs with pigmented long roots covered by the root sheaths. Colchicine poisoning is an uncommon, but potentially life-threatening toxicologic emergency. An overdose of colchicine inhibits cell division, and thus the most affected organs are those which have a high rate of cell turnover...

Rajyalaxmi Konathan, Sainath Kumar Alur
Olmsted syndrome (OS) is a rare disorder characterized by the combination of periorificial, keratotic plaques, and bilateral palmoplantar keratoderma. Synonyms are mutilating palmoplantar keratoderma with periorificial keratotic plaques (ORPHA659, MIM #614594 and #300918). A number sign (#) is used with this entry because of evidence that mutilating palmoplantar keratoderma with periorificial keratotic plaques (OS) is caused by heterozygous mutation in the TRPV3 gene on chromosome 17p13.2. We report three cases of OS, two females and one male in the same family, who presented with palmoplantar keratoderma, sparse scalp hair, cheilitis, and periorificial fissures...
