RESUMO
Lichen planopilaris (LPP) and its variants, mainly frontal fibrosing alopecia (FFA), affect the hair follicles causing cicatricial alopecia with a significant negative impact on self-confidence and quality of life (QoL). This systematic review investigates the psycho-emotional impact of LPP and its variants using PRISMA guidelines. The review revealed that LPP and FFA cause significant psychological distress and impaired QoL. Higher LPP disease activity and severity were associated with higher depression, higher anxiety scores, lower quality-of-life scores, and higher scores of role limitations (physical and emotional). Additionally, facial lesions in FFA patients, especially the eyebrows involvement can be very distressing, leading to impaired self-esteem and QoL. this negative impact of active and severe LPP and FFA on QoL and self-esteem of patients causes psychiatric conditions including anxiety and depression. Therefore, an early diagnosis must be encouraged in these patients.
RESUMO
BACKGROUND: The prevalence of skin cancers is constantly increasing in Morocco, and they have gradually become more aggressive due to a significant delay in the diagnosis. Our aim was to assess the levels of awareness and the influencing factors related to skin cancer knowledge in Morocco. METHODS: This cross-sectional study was carried out in Morocco through the medium of a validated questionnaire, which contained several items - demographics, skin cancer knowledge and attitudes towards skin cancer patients- during a period of 1 year (2014). RESULTS: Out of the 700 participants enrolled in the study, 17.9% had never heard of skin cancer, 32.5% had a low score of skin cancer knowledge, 66.7% had a moderate score, and only 0.85% had a high score of skin cancer knowledge. Further, 15.1% of the participants were under the assumption that this cancer is contagious. The sun was the most incriminated risk factor in skin cancer occurrence by 74.3% of the participants, and 57.9% of them believed that prevention is important through using various means of photoprotection. After univariate and multivariate analysis, the influencing factors related to the skin cancer knowledge in Morocco were: the socioeconomic status (P = 0.003, OR = 7. 3) and the educational level (p < 0.001, OR = 20. 9). CONCLUSIONS: Due to the lack of knowledge or the underestimation of skin cancer in our study population, efforts are needed to promote skin cancer surveillance behaviors in Morocco.

BACKGROUND: Similarly to psoriasis in adults, recent research has linked psoriasis to several comorbidities in children. The aim of this study was therefore to describe comorbidities associated with pediatric psoriasis, to investigate their relationship with psoriasis characteristics and severity, and to perform a review of the literature. METHODS: A cross-sectional study was performed on a sample of Moroccan children with psoriasis, in 2014-2016. RESULTS: A total of 64 pediatric psoriasis patients had metabolic comorbidities in association with psoriasis; 20 children had non-metabolic comorbidities; and 76 children had no comorbidity. The metabolic comorbidities were as follows: abdominal obesity, 40% (n = 64); overweight, 12.5% (n = 20); metabolic syndrome, 3.7% (n = 6); and dyslipidemia, 3.1% (n = 5); the non-metabolic comorbidities were atopy, 4.3% (n = 7); epilepsy, 3.1% (n = 5); celiac disease, 1.8% (n = 3); vitiligo, 1.8% (n = 3); alopecia ariata, 0.6% (n = 1); and valvular cardiopathy, 0.6% (n = 1). No cases of diabetes mellitus, obesity, or high blood pressure were recorded. Significant factors associated with metabolic comorbidity were extended psoriasis vulgaris >10% (P = 0.01; OR, 2.19), severe psoriasis especially pustular and erythroderma (P = 0.018; OR, 2), nail involvement (P = 0.016; OR, 1.5), face involvement (P = 0.01; OR, 1,59), resistance to topical treatment (P = 0.003; OR, 2.5) and alteration of quality of life (P = 0.02; OR, 1,7). There was no significant risk factor associated with non-metabolic comorbidity. CONCLUSIONS: Given the frequent association of pediatric psoriasis with many disorders, these comorbidities should be investigated and identified so that they can be taken into account in the management of psoriasis in order to avoid treatment failure. Regular follow up should be carried out in patients at risk of metabolic comorbidity.

INTRODUCTION: Actinic Lichen Planus (ALP) is a rare photosensitive variant of lichen planus. Four subtypes can be distinguished: pigmented, annular (AALP), plaque-like and dyschromic ALP. METHODS: This is a retrospective; descriptive and analytical study investigating the dermoscopic patterns of different subtypes of ALP in skin of color. RESULTS: Sixteen adult patients were included in this study; the majority of them were young females, while five patients with the pigmented subtype of ALP were more than 50 years old. This subtype was more prevalent in patients with phototype IV. AALP was described in men with a very dark phototype.In pigmented melasma-like ALP, dermoscopy showed an annular granular pattern, white reticular and circular Wickham striae (WS) with hypopigmentation lacking skin creases, dots inside circles and an eccentric pigmentation on circles. In ALP, annular, circular WS; and perifollicular white halos with follicular plugs were described. The black hole pattern with dotted vessels was seen in the dyschromic ALP. White-yellow-bluish WS were noticed in plaque-type ALP with circumferential radial lines at the periphery. CONCLUSIONS: This descriptive study of dermoscopic patterns of various subtypes of ALP in skin of color highlighted new dermoscopic descriptions that vary according to the clinical variant or the morphology; lesions distribution; and phototype. Also, many epidemiological differences were found between our results and the literature concerning the older age of onset in melasma-like pigmented ALP, and the male predominance in annular ALP.
RESUMO
INTRODUCTION: Dermoscopy has evolved over the years beyond distinguishing benign pigmented lesions from melanoma to diagnosing virtually all diseases in dermatology. Overwhelming evidence demonstrates its utility in improving diagnostic accuracy, reducing unnecessary biopsies and lesion monitoring. Dermoscopy is widely used in Western nations, hence most descriptions of lesions in literature are predominantly on Fitzpatrick skin types I-III. Current evidence shows that there are unique dermoscopic features in the dark skin as a result of pigment and pathological reactions. Nationwide surveys and reports have been conducted across several continents to highlight prevalence and factors influencing dermoscopy use with the hope of maximizing its apparent benefits. There are currently no such reports from Africa. OBJECTIVES: To evaluate dermoscopy use and its determinants among dermatologists in Africa. METHODS: A cross-sectional study. Online forms were e-mailed to individual practicing dermatologists and members of the African Society of Dermatologists and Venereologists. RESULTS: There were 196 respondents from 24 African countries. Half of them used dermoscopy. Training, practice settings and location, provision of dermatoscopes by institutions and knowledge of criteria were notable significant determinants. Multiple training exposures, knowledge of criteria, availability of dermatoscopes, use of both hand-held and videodermatoscopes, average number of patients seen per day, and a positive outlook towards dermoscopy were significant determinants of frequency of use. Leading impediments were lack of training and inadequate dermatoscopes in practice. CONCLUSIONS: Dermoscopy use in Africa is relatively low. Incorporating dermoscopy training into the curriculum with provision of dermatoscopes by training institutions will promote wider usage.

BACKGROUND: Necrobiosis lipoidica located to the breast; without evidence of glucose intolerance, is extremely rare, and its association to Crohn's disease is not usual. CASE PRESENTATION: We report an interesting case of an association of necrobiosis lipoidica of the breast and Crohn's disease in a 54-year-old Moroccan woman. Skin necrobiotic changes are a characteristic feature in necrobiosis lipoidica, but they are exceptional in metastatic Crohn's disease, since there are only three published cases of necrobiotic skin lesions on the lower leg resembling erythema nodosum in metastatic Crohn's disease. CONCLUSIONS: On the basis of this rare observation, necrobiosis lipoidica without evidence of glucose intolerance should be recognized as a possible cutaneous manifestation or association of Crohn's disease.

INTRODUCTION: A structured set of eight basic dermoscopic parameters (lines, clods, dots, circles, pseudopods, structureless, else, and vessels) including a total of 77 variables with corresponding descriptive and metaphoric vocabulary has been released for evaluation of skin tumors by the International Dermoscopy Society (IDS). OBJECTIVES: To validate the aforementioned criteria for the use in darker phototypes (phototypes IV-VI) via an expert consensus. METHODS: The two-round "Delphi method" was adopted, with an iterative process including two rounds of email questionnaires. Potential panelists were asked to take part in the procedure via email on the basis of their expertise in the dermoscopy of skin tumors in dark phototypes. RESULTS: A total of 17 participants were involved. All the original variables of the eight basic parameters reached agreement during the first round, except for "pink small clods" ("milky red globules") and "structureless pink zone" ("milky red areas"). Moreover, during the first round, panelists proposed a change of three existing items and the introduction of four new items, i.e., "black, small clods" ("black globules"), "follicular plugs", "erosions/ulcerations", and "white color around vessels" ("perivascular white halo"). All such proposals achieved agreement, thus being included in the final list, for a total of 79 items. There was consistency between the descriptive and metaphoric approaches in terms of scoring. CONCLUSIONS: Albeit most of the original items were considered applicable even for skin of color, there are some points of differences that physicians need to know. No significant preference was found between descriptive and metaphoric terminology among panelists.
RESUMO
Over the last few decades, dermoscopy has been showed to facilitate the non-invasive diagnosis of both benign and malignant skin tumors, yet literature data mainly comes from studies on light photo-types. However, there is growing evidence that skin neoplasms may benefit from dermoscopic assessment even for skin of color. This systematic literature review evaluated published data in dark-skinned patients (dermoscopic features, used setting, pathological correlation, and level of evidence of studies), also providing a standardized and homogeneous terminology for reported dermoscopic findings. A total of 20 articles describing 46 different tumors (four melanocytic neoplasms, eight keratinocytic tumors, 15 adnexal cutaneous neoplasms, seven vascular tumors, four connective tissue tumors, and eight cystic neoplasms/others) for a total of 1724 instances were included in the analysis. Most of them showed a level of evidence of V (12 single case reports and six case series), with only two studies featuring a level of evidence of IV (case-control analysis). Additionally, this review also underlined that some neoplasms and phototypes are underrepresented in published analyses as they included only small samples and mainly certain tones of "dark skin" spectrum (especially phototype IV). Therefore, further studies considering such limitations are required for a better characterization.
RESUMO
Hair and scalp disorders are of significant interest for physicians dealing with dark phototypes due to their prevalence and potential aesthetic impact resulting from a higher tendency for scarring. In order to facilitate their non-invasive diagnosis, several dermoscopic studies have been published, yet data are sparse and no systematic analysis of the literature has been performed so far. This systematic literature review summarizes published data on trichoscopy of hair and scalp diseases (trichoscopic findings, used setting, pathological correlation, and level of evidence of studies). A total of 60 papers addressing 19 different disorders (eight non-cicatricial alopecias, nine cicatricial alopecias, and two hair shaft disorders) were assessed, for a total of 2636 instances. They included one cross-sectional analysis, 20 case-control studies, 25 case-series, and 14 single case-reports, so the level of evidence was V and IV in 65% and 33% of cases, respectively, with only one study showing a level of evidence of III. Notably, although there is a considerable body of literature on trichoscopy of hair/scalp diseases, our review underlined that potentially significant variables (e.g., disease stage or hair texture) are often not taken into account in published analyses, with possible biases on trichoscopic patterns, especially when it comes to hair shaft changes. Further analyses considering all such issues are therefore needed.
RESUMO
Dermoscopy has been showed to facilitate the non-invasive recognition of several infectious disorders (infectiouscopy) thanks to the detection of peculiar clues. Although most of the knowledge on this topic comes from studies involving light-skinned patients, there is growing evidence about its use also in dark phototypes. This systematic literature review summarizes published data on dermoscopy of parasitic, bacterial, viral and fungal dermatoses (dermoscopic findings, used setting, pathological correlation, and level of evidence of studies) and provides a homogeneous terminology of reported dermoscopic features according to a standardized methodology. A total of 66 papers addressing 41 different dermatoses (14 bacterial, 5 viral, 11 fungal infections, and 11 parasitoses/bites and stings) and involving a total of 1096 instances were included in the analysis. The majority of them displayed a level of evidence of V (44 single case reports and 21 case series), with only 1 study showing a level of evidence of IV (case-control analysis). Moreover, our analysis also highlighted a high variability in the terminology used in the retrieved studies. Thus, although promising, further studies designed according to a systematic and standardized approach are needed for better characterization of dermoscopy of infectious skin infections.
RESUMO
Dermoscopic patterns of inflammatory dermatoses (inflammoscopy) have been extensively studied in the recent years, though data on patients with darker phototypes (IV-VI) are sparse. The aims of this systematic review were to summarize the current state of knowledge on inflammoscopy applied to skin of color and provide a standardized nomenclature of reported findings. Besides dermoscopic features, type of setting and magnification, number of cases, and histopathological correlation were analyzed. Eighty-five papers addressing 78 different dermatoses (25 papulosquamous dermatoses, 19 hyperpigmented dermatoses, eight hypopigmented dermatoses, four granulomatous dermatoses, two sclerotic dermatoses, five facial inflammatory dermatoses, and 15 miscellaneous conditions) for a total of 2073 instances were retrieved. Only one study showed a level of evidence of III (cross-sectional study), whereas 10 and 74 displayed a level of evidence of IV (case-control studies) and V (case-series and case-reports), respectively. Moreover, our analysis also highlighted that most of papers focalized on a limited number of dermatoses, with several conditions having only single dermoscopic descriptions. Additionally, few studies compared findings among phototypes belonging to the "skin of color" spectrum. Further studies designed according to a systematic approach and considering the above-mentioned issues are therefore needed.

INTRODUCTION: The characteristics and the prognostic value of regression in primary melanomas are controversial. OBJECTIVES: To further characterize "hot" and "cold" tumor's stromas and to investigate the association between dermoscopy, pathology, and the prognostic implications of regression. METHODS: A 14-year-collection-based retrospective analysis was carried out on 40 patients with confirmed regressive melanomas. RESULTS: The extent of regression in dermoscopy was associated with the stage of the regression (P = 0.05) and with the MelanA patterns in histology (P = 0.02). Blue-gray and gray-brown color of the peppering (P = 0.01), and the eccentric, multifocal character of the dermoscopic regression (P = 0.05) were associated with "hot" stromas (CD8+, Granzym B+). Focal histologic regression (regressing melanomas) was associated with a good outcome (P < 0.001), while a complete regression (regressed melanomas) was associated with melanoma-related death (P < 0.001). "Hot" stromas (CD8+ were significantly associated with survival at 10 years (P = 0.044), while "hot" stromas (Granzyme B+) were associated with the locoregional extension (P = 0.016), and the initial distant metastasis (P = 0.016). CONCLUSIONS: Dermoscopic features of regression in primary melanomas were associated with the stage of regression, its extent, and the "hot" or "cold" nature of the tumor stroma, with prognostic implications.
RESUMO
BACKGROUND: The International Dermoscopy Society (IDS) recently released a set of five basic dermoscopic parameters (vessels, scales, follicular findings, "other structures," and specific clues) encompassing a total of 31 subitems to standardize the use of dermoscopy in non-neoplastic dermatoses, yet they have been developed taking into account Caucasian/Asian skin, with consequent possible limitations if used in dark skin. OBJECTIVES: To validate the abovementioned criteria for the use in dark-skinned patients (phototypes IV-VI) through an expert consensus. METHODS: The two-round Delphi method was adopted, with an iterative process consisting of two rounds of email questionnaires. Potential panelists were recruited via e-mail from all over the world based on their expertise on dermoscopy of non-neoplastic dermatoses in skin of color. RESULTS: Twenty-two panelists took part in the validation process. All of the five originally proposed parameters and subitems reached agreement during the first round, aside from "follicular red dots." Additionally, during round 1, five new subitems were proposed (perifollicular scales distribution, follicular openings obliteration, broken hairs, eccrine pigmentation, and eccrine ostia obliteration), along with the possibility to change the denomination of parameter 3 (from "follicular findings" to "follicular/eccrine findings") and split it into two subparameters ("follicular findings" and "eccrine findings"). All such proposals reached agreement during the second round and therefore were included in the final list, for a total of 37 items. CONCLUSIONS: Although nearly all the dermoscopic criteria originally proposed by the IDS are applicable even to darker phototypes, several additional variables need to be assessed.

The sarcoidosis is a systemic granulomatous disease. It is usually characterized by skin manifestations which may be suggestive of progressive sarcoidosis with visceral involvement. We here report a case of pulmonary sarcoidosis revealed by the reactivation of an old cutaneous scar following a trauma occurred 20 years earlier. Radiological assessment showed mediastino-pulmonary sarcoidosis stage 2. The diagnosis of sarcoidosis should be suspected in patients with any recent scar modification in order to establish early management.

BACKGROUND: Dermoscopy has been shown to be a useful supportive tool to assist the diagnosis of several non-neoplastic dermatoses (i.e. inflammatory, infiltrative and infectious skin diseases), yet data on skin of colour is still limited. OBJECTIVES: To characterize dermoscopic features of non-neoplastic dermatoses in dark-skinned patients in order to identify possible clues that may facilitate the differential diagnosis of clinically similar conditions. MATERIALS & METHODS: Members of the International Dermoscopy Society were invited to submit cases of any non-neoplastic dermatosis developing in patients with Fitzpatrick Phototypes V-VI whose diagnosis had been confirmed by the corresponding gold standard diagnostic test. A standardized assessment of the dermoscopic images and a comparative analysis according to clinical presentation were performed. Seven clinical categories were identified: (I) papulosquamous dermatoses; (II) facial hyperpigmented dermatoses; (III) extra-facial hyperpigmented dermatoses; (IV) hypopigmented dermatoses; (V) granulomatous dermatoses; (VI) sclerotic dermatoses; and (VII) facial inflammatory dermatoses. RESULTS: A total of 653 patients (541 and 112 with Phototype V and VI, respectively) were recruited for the analysis. Thirty-six statistically significant dermoscopic features were identified for papulosquamous dermatoses, 24 for facial hyperpigmented disorders, 12 for extra-facial hyperpigmented disorders, 17 for hypopigmented disorders, eight for granulomatous dermatoses, four for sclerotic dermatoses and 17 for facial inflammatory diseases. CONCLUSION: Our findings suggest that dermoscopy might be a useful tool in assisting the diagnosis of clinically similar non-neoplastic dermatoses in dark phototypes by revealing characteristic clues. Study limitations include the retrospective design, the lack of a direct dermoscopic-histological correlation analysis and the small sample size for less common diseases.

Dermatomyositis is a systemic idiopathic disease characterized by a combination of both muscle and skin symptoms. It is a paraneoplastic dermatosis. Its association with rectal cancer has been rarely described in the literature. We here report the case of a female patient with paraneoplastic dermatomyositis associated with metastatic rectal adenocarcinoma presenting with clinical symptoms commonly found in subjects with paraneoplastic dermatomyositis. Other complementary examinations (CPK test + EMG + skin biopsy) were performed which confirmed this diagnosis. The patient underwent chemotherapy, but after the second cycle, she experienced a rapid worsening of her general condition and died after some days in a state of multisystem organ failure. This study aims to highlight paraneoplastic dermatomyositis' aggressive nature and to update current knowledge on the importance of chemotherapy in the management of neoplastic dermatomyositis.
