RESUMO
PURPOSE: The "Impact of scalp pruritus in dermatological consultations in Spain: The SCALP-PR trial" was initiated to address the common yet often insufficiently examined issue of scalp pruritus in dermatology. This condition leads to an uncontrollable urge to scratch, affecting the patients' quality of life and potentially causing scalp damage. This study aimed to explore the prevalence, patient profile, underlying conditios, and therapeutic approaches for scalp pruritus in Spain, and to assess the safety and efficacy profile, as well as the tolerability of a non-pharmacologic treatment. METHODS: From 2021 through 2022, 75 dermatologists enrolled a total of 359 patients in a study on scalp pruritus, approved by the Bellvitge University Hospital Research Ethics Committee, Barcelona, Spain. This evidence-based research combined a meta-analysis with observational study techniques focused on real-world evidence to examine the therapeutic impact on quality of life (QoL). Utilizing the Dermatology Life Quality Index (DLQI) for QoL assessments, the study evaluated the effectiveness of the topical product over 15 days. Data collection was conducted via an eCRF and analyzed with statistical methods to provide reliable insights into the management of scalp pruritus. RESULTS: The prevalence of scalp pruritus in Spain was found to be 6.9%, predominantly among women with a mean age of 52.5 years. The leading causes identified were seborrheic dermatitis and pruritus of undetermined etiology or sensitive scalp. Stress was noted as a key factor, with corticosteroids and hygienic measures being common therapies. The topical product demonstrated significant reductions in pruritus and scratching in more than 90% of patients after 15 days. Improvements were also seen in dermatological quality of life, with 87.1% of patients showing enhancements in DLQI scores. The product was well-received thanksto its cosmetic properties, with high ratings in texture, ease of application, and fragrance. CONCLUSION: The topical product studied is a safe, effective, and cosmetically appealing treatment, improving scalp pruritus in various etiologies for most patients. The results highlight the need for patient-center treatments in dermatology, providing important insights for clinical practice and future research.
RESUMO
Sensitive scalp is sensitive skin located on the scalp. Sensitivity is considered primary in the absence of an associated scalp disorder and secondary when caused by conditions such as psoriasis, seborrheic dermatitis, and atopic dermatitis. The clinical manifestations of primary sensitive scalp are subjective. Common presenting symptoms are burning, itching, trichodynia, and dysesthesia, often coinciding with hair loss. Clinically, the skin appears normal or red. An objective diagnosis based on laboratory or histologic findings is not possible. Triggers may be endogenous (e.g., stress and emotional or psychopathological disturbances) or exogeneous (e.g., topical products and cosmetics). Treatment must be individualized. Options include pimecrolimus, hydration with hyaluronic acid, and mesotherapy with plasma rich in growth factors.

BACKGROUND AND OBJECTIVE: Body dysmorphic disorder (BDD) is a mental disorder that is difficult to diagnose, causes a lot of suffering and is more prevalent in dermatology patients than in the general population. Our objective was to screen for possible cases of BDD in patients with acne and to determine the prevalence according to DSM-IV and DSM-5 criteria, as well as to analyse the relationship between dermatological and sociodemographic variables. METHODS: A total of 245 patients diagnosed with acne in 11 dermatological centres in Spain were included in the study by members of the Aragon Psychodermatology Research Group and Spanish Research Group of Psychiatric Dermatology. We used the Body Dysmorphic Disorder Questionnaire (BDDQ) as a screening tool. RESULTS: In our sample, we obtained a prevalence for BDD of 10.6% (95% CI: 7.6-13.6%). The prevalence was the same with DSM-IV or DSM-5 criteria. Possible cases of BDD were predominantly women (P = 0.021), and 56% had non-inflammatory lesions vs. 30% of negative patients (P = 0.002). Positive patients as possible cases of BDD spent more than two hours on average a day worrying about their appearance. Most people only worried about one part of their body (86%), and in 95% of the cases, the part of their body that worried them was the face. The three most frequent compulsive behaviours in patients who screened positive for BDD were mirror checking (90.7%), camouflaging (79.1%) and using make-up (72.1%). CONCLUSIONS: As a consequence of the high prevalence of possible cases of BDD in patients with acne observed in our study, there is a need for dermatologists to screen for BDD so that they can be referred to a mental health unit to confirm the diagnosis and be offered treatment to reduce the progression of psychosocial deterioration and the development of comorbid disorders.

Sensitive skin has traditionally been viewed as a cosmetic problem or as a purely psychosomatic alteration with a major subjective component. Different studies of its pathophysiologic etiology, however, have shown it to be a complex entity that several authors now consider to be a neurodermatological syndrome. Because of this complexity, skin sensitivity can be difficult to diagnose and treat, particularly considering that it may present with another disease. Simple tools applicable to clinical practice are thus necessary to identify and manage this disease as an independent entity. In this study, we perform a practical review of the most recent scientific advances in the area of sensitive skin that justify it being considered an individual entity, and provide tools for its identification and treatment. We propose diagnostic and treatment algorithms based on evidence from the literature and our experience and expertise.

BACKGROUND: There is currently little information available on the management of patients with psoriasis in the daily clinical practice of dermatologists in Spain. OBJECTIVE: The aim of this study was to survey a group of Spanish dermatologists with particular expertise in the management of psoriasis to determine their opinions on the protocols used in routine clinical practice. MATERIAL AND METHODS: A cross-sectional study based on an online survey about the management of psoriasis sent to 75 dermatologists. The survey, which was specifically designed for the study, included 12questions on different aspects of clinical practice in the treatment of moderate to severe psoriasis. RESULTS: The response rate was 96% (n=72). Biologics were the most widely used monotherapy option. In total, 64.3% of respondents reported that their patients used conventional systemic therapies for 1 to 2years before switching to a biologic drug and that the main reason for the switch was unstable control of disease activity. Overall, 85.7% assigned a "high" or "very high" importance to the use of a Psoriasis Area Severity Index score of <3 as a treatment goal. The drugs of choice among the respondents were etanercept for pediatric patients (78.6%), adalimumab and etanercept for patients with psoriatic arthritis (64.3%), and ustekinumab in patients frequently away from home (78.6%) and patients with a history of multiple sclerosis, demyelinating diseases (64.3%), or poor adherence to treatment (71.4%). CONCLUSION: This study provides a unique overview of the opinions of a representative sample of expert dermatologists on the current use of biologics for the treatment of psoriasis in Spain.

Urticarial vasculitis (UV) is a mainly leucocytoclastic vasculitis with urticarial plaques. Treating these patients is challenging as the available treatments have poor efficacy. Oral corticosteroids are considered the first-line treatment, but H1 antihistamines, dapsone, colchicine, antimalarials, ciclosporin and antileucotrienes have all been tried also. However, because of their adverse effects and/or lack of efficacy, new agents are still needed. Omalizumab, an anti-IgE antibody, shows efficacy in chronic spontaneous urticaria, and might also be a good treatment for angio-oedema and urticarial vasculitis. To our knowledge, there have been only seven relevant case reports published in the English literature. We add a new case of severe chronic recurrent urticarial vasculitis refractory to all of the drugs mentioned above. We started the patient on subcutaneous omalizumab 300 mg every 4 weeks, which produced clinical improvement within the first month and total remission in the fifth month. The patient has remained stable for 23 months, and follow-up is ongoing.

Hair plays a significant role in body image, and its appearance can be changed relatively easily without resort to surgical procedures. Cosmetics and techniques have therefore been used to change hair appearance since time immemorial. The cosmetics industry has developed efficient products that can be used on healthy hair or act on concomitant diseases of the hair and scalp. Dyes embellish the hair by bleaching or coloring it briefly, for temporary periods of longer duration, or permanently, depending on the composition of a dye (oxidative or nonoxidative) and its degree of penetration of the hair shaft. The dermatologist's knowledge of dyes, their use, and their possible side effects (contact eczema, cancer, increased porosity, brittleness) can extend to an understanding of cosmetic resources that also treat hair and scalp conditions.

Epidemiologic studies indicate that ever larger numbers of people report having sensitive skin, for which a European prevalence of 50% is estimated. Sensitive skin is characterized by hyperreactivity, with manifestations varying in relation to many factors. The pathogenesis of this disorder is poorly understood, although studies point to a biophysical mechanism. Objective diagnosis of sensitive skin is difficult, as information comes mainly from the patient's report of symptoms in the absence of effective, strongly predictive tests because of great interindividual variability in skin sensitivity. Substances that trigger a reaction in hypersensitive skin also vary greatly. The impact of this syndrome on quality of life is considerable and patients often present psychiatric symptoms; therefore, dermatologists should explore this possibility when taking a patient's history. Patient cooperation and physician persistence are both essential for treating sensitive skin.

Trichilemmal horn, or trichilemmal keratosis, is an uncommon benign neoplasm of follicular lineage with trichilemmal differentiation. The essential characteristics of this tumor are its clinical presentation in the form of a cutaneous horn with trichilemmal keratinization apparent in the histology study (with a hyperplastic epithelium giving rise to dense, orthokeratotic eosinophilic keratin). We present a new case of this type of tumor in an 82-year-old woman who developed a solitary lesion on her scalp after surgical removal of a trichilemmal cyst. On the basis of the pathology report, the tumor was diagnosed as trichilemmal horn. We review the 33 reports of this tumor in the literature to date.

Glomeruloid haemangioma is considered a specific marker of POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) syndrome and it is usually but not always associated with multicentric Castleman's disease. We report a 78-year-old man who presented with a single, red-violet soft nodule with superficial telangiectases on the scalp. Histopathologically, the lesion consisted of lobules of coiled aggregated capillaries that involved the lumina of dilated vascular structures, mimicking renal glomeruli. A collagenous stroma separated the capillary lobules, and eosinophilic, periodic-acid-Schiff positive globules of varying sizes and shapes were seen within the cytoplasm of endothelial cells. Immunohistochemical studies with antibodies against IgA and IgG, and against the kappa and lambda light chains of immunoglobulins showed immunoreactivity within the eosinophilic globules. Results of complete blood count, liver, renal and thyroid function tests, fasting blood sugar measurement, serum levels of oestradiol, testosterone, prolactin and cortisol, serum protein electrophoresis, immunoelectrophoresis and immunofixation yielded normal or negative results. No Bence-Jones proteinuria was found in a sample from a 24-h urine collection. To our knowledge, only two cases of glomeruloid haemangioma have been previously reported in patients without POEMS syndrome. We describe the third case of glomeruloid haemangioma in a patient without features of POEMS syndrome.

BACKGROUND: Selective immunostaining for calretinin labels the innermost layer of the outer root sheath of normal hair follicles, which is difficult to distinguish with hematoxylin-eosin staining. OBJECTIVE: The aim of this study was to determine whether immunohistochemistry for calretinin allows identification of cutaneous adnexal tumors with follicular differentiation towards cells of the outer root sheath. MATERIAL AND METHODS: We analyzed the staining pattern for calretinin by immunohistochemistry in 49 biopsies of cutaneous adnexal tumors with follicular differentiation. RESULTS: Fifteen biopsies corresponded to trichilemmomas/inverted follicular keratosis and had staining for calretinin in the epithelium of the most superficial areas of the lesions and in squamous eddies. Ten were trichilemmal cysts, which displayed staining of the cyst wall. Three were basal cell carcinomas with variable staining according to the type of follicular differentiation in each variant. One was a panfolliculoma that had focal staining. Two were folliculosebaceous cystic hamartomas with staining of the excretory duct of the sebaceous glands. Two pilomatricomas and 3 proliferative trichilemmal tumors had positive staining in the cellular layers close to the lumen of the cystic structures. Nine trichoblastomas/trichoepitheliomas, 2 infundibular cysts, 1 dilated pore of Winer, and 2 acanthomas of the follicular sheath were negative for calretinin. CONCLUSION: Immunohistochemistry for calretinin allows identification of cutaneous adnexal tumors of the hair follicle or a component of the follicle with differentiation towards cells of the outer root sheath.

Mycosis fungoides is the most common type of primary cutaneous T-cell lymphoma. Several rare clinicopathological variants of mycosis fungoides have been described. Patients with these variants often also have classic mycosis fungoides at other sites of the body. Anetoderma is a cutaneous disorder in which multiple, oval lesions or atrophic plaques with wrinkled surface develop progressively due to loss of the dermal elastic tissue. Primary anetoderma occurs when there is no underlying associated disease and it arises on clinically normal skin, whereas secondary anetoderma appears in the same site as a previous specific skin lesion. There is a large list of heterogeneous dermatoses associated with secondary anetoderma. Two patients developed areas of secondary anetoderma on plaque stage lesions of mycosis fungoides. The lesions consisted of exophytic nodular lesions, with very soft consistency on palpation, scattered over the hyperpigmented plaques in one patient and violaceous indurated plaques with overlying epidermal atrophy and mild scale in the other. Histopathological study demonstrated that the cells involving the dermis were mainly T-helper lymphocytes, with few histiocytes and some multinucleate giant cells engulfing distorted elastic fibres. Elastic tissue stain demonstrated that elastic fibres were almost completely absent in the dermis of the anetodermic lesions. Anetodermic mycosis fungoides should be added to the list of clinicopathological variants of mycosis fungoides and mycosis fungoides should also be considered as a possible disease causing secondary anetoderma. Anetodermic mycosis fungoides shows clinical and histopathological features different from those of granulomatous slack skin.
