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.

Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare, slow-growing adnexal skin tumor with about 250 documented cases. We present a case involving a 66-year-old woman who was treated with ovulation inductors 30 years ago and underwent surgeries for meningioma 20 years ago and invasive galactophoric adenocarcinoma of the left breast 12 years ago. She presented with a gradually enlarging, solid, skin-colored tumor on her scalp, located along an old surgical scar initially diagnosed as a keloid by her surgeon. Clinical and dermoscopic evaluations suggested basal cell carcinoma or a metastatic tumor. Confocal microscopy showed deep infiltration without specific diagnostic clues. However, histopathological examination, immunohistochemistry, and comprehensive investigations confirmed the diagnosis of PCACC. A wide local excision was performed, with no recurrence noted during the two-year follow-up. This case highlights the challenges of diagnosing PCACC through clinical, dermoscopic, and confocal methods. Histological analysis remains essential, particularly to distinguish it from metastatic lesions, emphasizing the need for a thorough diagnostic approach in such cases.
RESUMO
INTRODUCTION: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, accounting for 20% of malignant skin tumors. Dermoscopy is a very useful tool for diagnosing cSCC, and its findings are confirmed through histopathological studies. OBJECTIVES: to describe the different dermoscopic structures of invasive cSCC and investigate their association with the clinical form and histopathological grade of differentiation. METHODS: We conducted a cross-sectional study, collecting all patients diagnosed with squamous cell carcinoma over a period of 5 years. The study population was divided into two groups based on histological differentiation (well-differentiated and non-well-differentiated) and clinical form ( nodulo-ulcerative and nodular). Various dermoscopic parameters were compared between these groups. RESULTS: Out of 72 invasive cSCC, 81.9% were well-differentiated, while 18.1% were non-well-differentiated. The clinical form of cSCC was nodulo-ulcerative in 83.3% of cases and nodular in 16.7%. Well-differentiated tumors showed dotted, glomerular and hairpin vessels, along with a predominant white pattern characterized by centrally distributed keratin as well as white circles, and whitish perivascular halo (P < 0.05). The distribution of these white structures was radial in nodulo-ulcerarive lesions, whereas in nodular lesions, their distribution, as well as that of keratin, was more diffuse (P < 0.05). Non-well-differentiated tumors showed a combined white-red pattern with the predominance of arborizing vessels (P < 0.05). CONCLUSIONS: Our results show the reliability of dermoscopy as a tool for distinguishing between well- and poorly differentiated cSCC. This distinction is characterized by an increase in predominantly arborizing vessels and a corresponding decrease in white structures as the tumor progresses from a well-differentiated to a poorly differentiated state. Additionally, the nodulo-ulcerative form exhibits a central distribution of keratin, while the nodular form displays a diffuse distribution.
RESUMO
Malignant melanocytic matricoma (MMM) is an extremely rare skin malignant neoplasm composed of epithelial cells with matrical differentiation and dendritic melanocytes. We found only 11 cases reported in the literature to date according to the databases consulted (PubMed/Medline, Scopus, and Web of Science). Here, we report a case of MMM in an 86-year-old woman. A histological examination showed a dermal tumor with a deep infiltrative pattern, without an epidermal connection. On immunohistochemical staining, tumor cells were positive for cytokeratin AE1/AE3, p63, and beta-catenin (nuclear and cytoplasmic staining) and negative for HMB45, Melan-A, S-100 protein, and androgen receptor. Melanic antibodies highlighted scattered dendritic melanocytes in tumor sheets. The findings did not support the diagnosis of melanoma, poorly differentiated sebaceous carcinoma, and basal cell carcinoma, but supported the diagnosis of MMM.
RESUMO
Adnexal carcinomas are rare, accounting for less than 1% of skin carcinomas. Sclerosus carcinoma of the sweat glands was first described by Goldstein et al. in 1982. We here report the case of a 33-year-old female patient with a retracted perianal skin lesion. Histological examination of perilesional skin biopsy, immunohistochemistry, and negative results of laboratory tests, radiological and endoscopic investigations allowed for the diagnosis of eccrine sclerosus carcinoma. This is a rare tumor, usually characterized by facial localization and slow but aggressive progression. It poses problems in differential diagnosis with benign and malignant tumors; hence the challenge encountered by pathologist of suspecting this carcinoma in patients with any sclerotic and infiltrating skin lesion characterized by slow progression, in a context of preservation of the general state and in the absence of neoplastic history as well as of feeling free to ask for new deep biopsies when in doubt.

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis for which accurate epidemiological data are limited and therapy remains a challenge. The primary study's aim was to examine all cases of PG observed in our department over a 6-year period in order to describe the relevant characteristics and outcome under therapy. Fourteen patients were included (5 women, 9 men). The average age of our patients was 40,15 years. The classical, ulcerative form was found in 10 cases (71.42%), the pustular form in 4 cases (27.57%) and PG was multifocal in 4 cases. The PG was located preferentially to the lower limbs. Histological examination was realized in all patients and objectified inflammatory infiltrate composed of polymorphonuclear neutrophils in all cases with vasculitis in 4 cases. Six patients (42.85%) had associated disease at diagnosis of PG, including inflammatory bowel disease in two cases (14.28%), a blood disease in 2 cases (14.28%), lymph node tuberculosis and inflammatory arthritis in 1 case (7%). The most frequent first-line treatments were oral corticosteroids (7 cases) and other treatments used were colchicine in 2 cases, topical corticosteroids in 3 cases with good clinical evolution. Our study confirms that PG is a rare disease, associated in almost half of cases with systemic disease already present at diagnosis; in our Moroccan background, it is most often inflammatory bowel disease, hematological or solid cancer and tuberculosis.

Pemphigus vegetans is a rare form of pemphigus. It accounts for only 2%. There is a broad range of effective options available to treat this disease: topical and/or oral corticosteroids as first-line treatment, immunosuppressants such as Azathioprine, Cyclosporine, Methotrexate, Cyclophosphamide and Mycophenolate mofetil to reduce the side effects of steroids. Some patients are resistant to all these treatments. Rituximab has revolutionized the treatment of pemphigus, pemphigus vegetans in particular. We here report the case of a 42-year old female patient, admitted with pemphigus vegetans confirmed by histology. She initially received corticosteroid therapy associated with immunosuppressive therapy without improvement. Then she was treated with Rituximab and had an unexpected positive outcome.

Morphea, also known as localized scleroderma, is defined as a sclerosus skin condition that can extend to the subcutaneous tissue but with no Raynaud's phenomenon or visceral involvement. Some clinical forms may have a functional and aesthetic impact, hence the interest of treatment of early stage inflammation. We here describe the epidemio-clinical, therapeutic and evolutionary features of different forms of morphea, by reporting a series of 24 cases.

INTRODUCTION: Tinea capitis is a scalp infection caused by different fungi. Etiological diagnosis is based on suggestive clinical findings and confirmation depends on the fungus growth in culture. However, it is not always possible to perform this test due to lack of availability. The association of clinical and dermatoscopic findings in suspected cases of tinea capitis may help the identification of the etiological agent, facilitating precocious, specific treatment. MATERIALS AND METHOD: We report a prospective descriptive analytical study of 34 children with tinea capitis. We performed a trichoscopic examination of all patients; only six children were able to have the mycological culture. RESULTS: Trichoscopy was abnormal in all 34 patients; it showed hair shaft abnormalities and, in some cases, scalp disorders too. We found that the comma and corkscrew appearance was found in microsporic tinea capitis, V-shaped hair was mainly seen in inflammatory tinea capitis, scales and follicular keratosis in non-inflammatory tinea capitis, and crusts and follicular pustules in inflammatory tinea capitis. Finally, erythema was seen in trichophytic and inflammatory tinea capitis. CONCLUSION: We propose a classification of trichoscopic signs of tinea capitis. This classification will enable rapid diagnosis and prediction of the type of fungus before mycological culture, thus a faster and more adapted management. Our study shows the importance of trichoscopy in the diagnosis and monitoring of tinea capitis. We suggest further prospective studies with a larger number of patients with tinea capitis, having performed mycological culture, to confirm this classification.

BACKGROUND: Nevus sebaceus of Jadassohn (NSJ) is a complex cutaneous hamartoma with various clinical appearances. AIM: To describe different dermoscopic patterns of this nevus according to its evolutionary stages. METHODS: This was an analytical study of NSJ carried out in the Department of Dermatology at the University Hospital Hassan II, Fez, Morocco. RESULTS: Thirteen patients with a NSJ were enrolled in the study. Elevated verrucous plaques were noticed in 9 patients, homogeneous tumors were described in 2 NSJ, an alopecic patch was found in 1 case, and we had 1 case of malignant transformation into basal cell carcinoma. The dermoscopic aspects of NSJ described in our study were yellowish or brown globules aggregated in clusters on a yellow background. This pattern was significantly related to the first stage of an alopecic patch (p = 0.001). Whitish-yellow lobular aspect and grayish papillary appearance were significantly related to verrucous plaques (p = 0.003). Homogeneous yellow-whitish pattern was related to nodules (p = 0.005). CONCLUSION: The establishment of specific dermoscopic features of NSJ according to its evolutionary stages is important for its diagnosis and especially its monitoring in order to detect malignant transformation.
RESUMO
BACKGROUND: The usual stereotypical dermoscopic pattern associated with dermatofibromas is a pigment network and central white patch. However, this pattern may be difficult to diagnose in some variant cases. We aimed to describe dermoscopic patterns of dermatofibroma according to its histopathological subtypes, with special emphasis on new and rare dermoscopic features. METHODS: This prospective study, which was conducted between September 2015 and May 2016 in the Department of Dermatology, University Hospital Hassan II, Fez, Morocco, included 100 cases of dermatofibroma confirmed on clinical and histological grounds. Each lesion was scored for classic, previously reported, or new dermoscopic features. RESULTS: All our Moroccan patients had a dark skin phototype (Fitzpatrick scale types IV and V). A total of 14 morphological dermoscopic structures were distinguished, and 17 dermoscopic patterns were observed, with the most common pattern being the central white patch and peripheral pigment network (21%). New patterns observed in our study were a white ring around an ulceration (6%), a pigment network with a pigmented ring around follicular openings (2%), and a discreet peripheral network and starlike white patch (3%). A patchy network with white patches was significantly noted in atrophic dermatofibroma (p = 0.01); vascularization was described in both aneurysmal and hemosiderotic dermatofibromas (p = 0.002); and a white ring around an ulceration was noted in aneurysmal dermatofibroma (p < 0.001). CONCLUSIONS: We provide a description of dermoscopic patterns of dermatofibroma according to its histological subtypes in a dark skin phototype, along with a new report of a white ring around an ulceration as a significant pattern in aneurysmal dermatofibroma.

Basosquamous carcinoma (BSC) is a rare skin cancer which has areas of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) and a transition zone between them. However, dermoscopic features of BSC are not well described in the literature, except for two studies. The aim of this case study was to better identify and clarify the role of dermoscopy in the diagnosis of BSC, although histological confirmation is necessary.

INTRODUCTION: In pemphigus, there still is no consensus on parameters mesuring clinically the disease severity. The aim of this study is to use the Japanese severity index in Moroccan patients with pemphigus. METHODS: Multicenter prospective study from September 2007 to September 2009 including consecutive patients with confirmed pemphigus. We used the Japenese severity index for pemphigus. For each patient, the score was calculated at diagnosis and at 6 months of follow-up and correlated to type of pemphigus; mean dosage of corticosteroids and clinical statuts at 6 months: dead or not. RESULTS: Fifty six patients were included, 20 men and 36 women, mean age 46.62 ± 15.9 years. At diagnosis, the mean initial score was 7.7 + 2.36; at six months, it was 1.61 + 1.83. The score variation at 6 months and inclusion was 6.19 ± 2.18 for deep pemphigus and 5.43 ± 2.85 for superficial pemphigus (p = 0,3 non significant). At six months, 4 patients were dead: their initial score was 11 + 1.41 while the initial score in the 52 patients was 7.4±2.03 (p = 0,001, significant). Data showed no correlation between initial severity scores and cumulative dosage of corticosteroids at 6 months (Pearson coefficient of correlation 0.144; p = 0.580). CONCLUSION: In this study, initial severity scores for pemphigus were high and decreased at 6 months of treatment. Both deep pemphigus and superficial pemphigus were severe as their score variation was similar. Japenese severity score is useful for Moroccan patients with pemphigus.
