A case report of squamous cell carcinoma mimicking interdigital intertrigo.

Squamous cell carcinoma (SCC), also known as epidermoid carcinoma, represents the most common malignant tumor affecting the nails. A 60-year-old tailor with no significant medical history presented with a three-year history of macerated skin between the toes, previously treated with a topical antifungal. Dermatological examination revealed a verrucous, infected ulceration with infiltrated and hyperkeratotic edges, characterized by a whitish, fissured base. This lesion in the fourth interdigital space and extended onto the dorsal surface of the foot without any other associated symptoms. The clinical diagnosis identified it as a neoplastic ulceration. An initial biopsy found keratoacanthoma but showed no malignant features. However, follow-up biopsy at our department revealed moderately differentiated SCC. Surgical resection was successful in treating our patient. Diagnostic errors due to insufficient understanding of the pathology and inadequate biopsy methods contribute to the progression of SCC. Surgery is the main treatment for such malignant tumors.

Monkeypox 2022 Outbreak: How Alarming Is the Situation? Epidemiological and Clinical Review.

Monkeypox is a disease caused by Orthopoxvirus, which also includes the smallpox virus. Several endemics have been reported on the African continent, typically in the western and central regions. However, since 13 May 2022, there have been several cases reported from different member states; the number of confirmed cases in 1 month exceeded the total number of cases reported outside the African continent since the first case in 1970. The World Health Organization (WHO) and Centers for Disease Control (CDC) consider monkeypox as an important disease for global public health. The clinical manifestations and laboratory findings in patients with monkeypox remain unclear. In this brief review, we investigated and compared the different characteristics already reported in cases of monkeypox.

Site Injection Reaction, Maculopapular Rash, and Rosacea Exacerbation after COVID-19 Vaccination.

To date, the occurrence of adverse events following immunization after COVID-19 vaccine is rare, and their report is still very poor; however, causality assessment is conducted to identify the associated cause, if they occur. In this case report, we present a case of an association of three cutaneous manifestations (maculopapular exanthem with enanthem, site injection reaction, and rosacea exacerbation) occurring three days after taking the first dose of AstraZeneca AZD1222 vaccine.

Skin Reactions to Personal Protective Equipment among First-Line COVID-19 Healthcare Workers: A Survey in Northern Morocco.

OBJECTIVES: Health care workers (HCWs) adopted several protective measures, including hand hygiene and wearing personal protective equipment (PPE) during the COVID-19 outbreak. However, the frequent use of these preventive measures can lead to skin reactions. Our study aimed to determine the frequency of these reactions in Northern Morocco. In addition, we also looked at the risk factors and the consequences of these injuries on work efficiency and performance. MATERIALS AND METHODS: An anonymous online survey was used to collect data, which was sent to 500 health workers in the study region. Descriptive and inferential statistics were used to analyze the data on IBM SPSS software. RESULTS: In total, 273/500 responded to the questionnaire (55%). For the participants' profession, 41% were doctors, 32% were nursing staff, and 26% held other jobs. The general prevalence rate of adverse reactions for all health workers was (80%), including skin problems: after wearing goggles (58%), after wearing surgical masks and respirators (57%), after handwashing and wearing gloves (45%), after wearing a face shield (23%), and after wearing protective clothing (11%). Bleach immersion was highly significantly associated with hand reaction (OR: 2.9, 95% CI: 1.77-4.90; P < 0.001). Moreover, we found a statistically significant association between hand cream use more than twice daily and fewer reactions (OR: 1.9, 95% CI: 0.98-3.77; P = 0.038). The skin reactions related to goggles use were also significantly associated with use duration (OR: 1.7, 95% CI: 0.988-3.12; P = 0.05). Similarly, wearing masks and N95 respirators and their related adverse reactions were significantly associated with use duration (OR: 0.5, 95% CI: 0.20-0.7; P = 0.02). In addition, adverse reactions of regular use of protective clothing were related to the frequency of its use per shift (OR: 3.5, 95% CI: 1.47-8.54; P = 0.05). CONCLUSIONS: Our survey-based study showed that the prevalence of these skin reactions in our context should not be neglected. The length of daily wearing time and the frequency of PPE uses were the most implicated factors. More attention must be paid to these reactions for better care of HCWs during these critical times.

Clinical and histological patterns and treatment of pyoderma gangrenosum.

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.

A Review of the Dermatological Manifestations of Coronavirus Disease 2019 (COVID-19).

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has affected 210 countries and territories around the world. The virus has spread rapidly, and the disease is still extending up to now. The pathophysiology for SARS-CoV-2 has not been well elucidated, and diverse hypotheses to date have been proposed. Initially, no skin manifestations were observed among patients with COVID-19, but recently a few cases have been described. In this review, we discuss these various cutaneous manifestations and skin problems related to personal protective equipment, as well as different cutaneous anti-COVID-19 drug-associated reactions. We also focus on the currently proposed managements of these rare manifestations.

[Descriptive dermoscopic study of a series of 100 patients with basal cell carcinoma diagnosed in Morocco]. / Étude descriptive dermoscopique d'une série de 100 carcinome basocellulaires diagnostiqués au Maroc.

INTRODUCTION: Dermatoscopy is an innovative non-invasive technique for clinical morphology of pigmented lesions and skin tumor. The purpose of our study was to highlight the morphological and dermoscopic features of basal cell carcinoma (CBC) in our study population. METHODS: We conducted a prospective unicentric study over a period of 2 years. We used dermoscopy in all patients with BCC. Statistical analysis was performed using SPSS software version 17. RESULTS: The study included 100 patients with BCC, the average age of patients was 51.87 years, with a sex ratio F/M = 0.6. BCC most commonly occurred in the face and most patients were prototype III and IV. We established conventional and non-conventional dermatoscopic criteria. Our study showed that there is a significant relationship between prototype and the degree of BCC pigmentation. CONCLUSION: This study highlighted the key role of dermoscopy in detecting small-sized BCC and in facilitating the diagnosis of pigmented BCC.

[The role of the micrographic surgery in the management of basal cell carcinoma: experience in the Department of Dermatology, at the Hassan II University Hospital, Fes, Morocco]. / L'intérêt de la chirurgie micrographique dans la prise en charge du carcinome basocellulaire: expérience du service de dermatologie CHU Hassan II de Fès, Maroc.

Mohs micrographic surgery (MMS) is a technique allowing for intraoperative histologic assessment of surgical margin of malignant tumors. This study aims to highlight the role of MMS in the achievement of radical healing of basal cell carcinoma (BCC) in our patients. We conducted a study of 29 patients with basal cell carcinoma of the face over a period of 5 years. The median age of patients was 45.8 years (12-80). The sex-ratio M/F was 1.23. One-stage surgical procedure was sufficient to obtain complete resection in 51% of cases. Three-stage surgical procedure was needed in 14% of the cases. The mean duration of one-stage surgical procedure was 1 hour. No complications were reported in the postoperative period and sequelae were simple. The aesthetic and functional result was satisfactory. No recurrence was noted. BCC accounts for approximately 80% of all skin cancers. The decision to use MMS to treat BCC is based on three variables: the seat and the size of the tumor, its histological appearance with the identification of resection margin and its recurrent nature. MMS is currently the most effective method in the treatment of BCC and allows maximum healthy tissue preservation. It is a safe and repeatable surgical procedure based on team work and adapted to the treatment of patients with BCC who are at high risk of recidivism. The aesthetic and functional results are satisfactory. Recurrence rate at 5 years is 10 times lower than with the other methods.

Etude descriptive dermoscopique d'une série de 100 carcinome basocellulaires diagnostiqués au Maroc

Introduction: la dermatoscopie est une technique d'examen non invasive, permettant de donner un nouveau regard de la morphologie clinique des lésions pigmentées et des tumeurs cutanées. Nous montrons à travers notre série les caractéristiques morphologiques dermotoscopiques du carcinome basocellulaire (CBC) chez notre population.Méthodes: notre étude est une étude prospective unicentrique étalée sur une période de 2 ans. Nous avons utilisé le dermoscope chez tous les patients ayant un CBC. L'analyse statistique était réalisée à 'aide du logiciel SPSS version 17.Résultats: on avait recensé 100 CBC, L'âge moyen des patients était de 51,87 ans, avec un sex ratio F/H = 0,6. Le visage était la localisation la plus fréquente et la plupart des patients étaient de phototype III et IV. On a distingué des critères dermatoscopiques classiques et non classiques. On a montré qu'il existe une relation significative entre le phototype et le degré de la pigmentation des CBC. Conclusion: dans ce présent travail, le dermoscope était bénéfique d'une part pour détecter les CBC de petite taille, d'autre part pour faciliter le diagnostic des CBC pigmentés

Painful tumors in a patient with neurofibromatosis type 1: a case report.

BACKGROUND: Herein, we report an unusual case of multifocal glomus tumors in the same hand in a patient suffering from neurofibromatosis type 1. CASE PRESENTATION: The patient was a 37-year-old Moroccan woman, suffering from neurofibromatosis type 1, with intense pain in the fingers, successfully treated with the excision of the tumors. Histology of the lesions confirmed the diagnosis of glomus tumor. CONCLUSION: We present this case to support the association between glomus tumors and neurofibromatosis type 1. Thus, we strongly recommend that one should suspect a glomus tumor in patients with neurofibromatosis type 1 if such patients have symptoms from finger pulp or nails.

A painless glomus tumor: a case report.

BACKGROUND: Glomus tumor is a benign and vascular hamartoma that originates from the neuromyoarterial cells of the normal glomus apparatus in the reticular dermis. The etiology of glomus tumors is unknown. It usually presents as a small, slightly raised, bluish or pinkish-red, painful nodule of the fingertips and the pulp. we report an atypical case of a patient of painless glomus tumor. CASE PRESENTATION: Our patient, a 60-year-old Moroccan man, had a 2.5 cm purplish painless soft tumor, covered with melliciric and hemorrhagic crusts, involving the first phalanx of his right index finger. This tumor was compressing his nail plate. No bony lesions were identified by radiographic studies, but magnetic resonance imaging was suggestive of glomus tumor. Surgical excision was performed with directed healing. CONCLUSIONS: The diagnosis of a glomus tumor is an eventuality even in the absence of pain.

Dermoscopy of skin metastases from breast cancer: two case reports.

BACKGROUND: Cutaneous metastatic breast cancer is the most common cutaneous metastatic malignancy in women. The assessment of cutaneous metastatic disease can be perplexing because the clinical presentation appears similar to other skin malignancies like angiosarcoma or melanoma, or benign diseases like cellulitis and lymphedema. To date, only a limited number of dermoscopic images of cutaneous metastatic solid tumors, especially breast cancer, have been published. CASE PRESENTATION: The authors report two Moroccan cases highlighting dermoscopy as a quick tool to recognize skin metastasis of breast cancer in two different clinical presentations. A 51-year-old Moroccan woman presented with nodules of various sizes on and around a mastectomy scar, and a 65-year-old Moroccan woman presented with cellulitis-like lesions on her chest wall and her back. Dermoscopic features were similar in the two cases with findings of yellow central areas, polymorphic vessels, whitish bright lines, whitish structureless areas, and linear irregular fissure-like depressions on a pink-orange background. CONCLUSIONS: The recognition of dermoscopic patterns of cutaneous metastasis of breast cancer is not only useful to facilitate diagnosis at an early stage and to rule out other differentials, especially in difficult presentations such as cellulitis-like lesions or lymphedema, but it may also be used by physicians in monitoring mastectomy scars.

Rare tumor in unusual location - glomus tumor of the finger pulp (clinical and dermoscopic features): a case report.

BACKGROUND: Glomus tumors are rare, benign, vascular neoplasms arising from the glomus body. Although they can develop in any part of the body, they commonly do so in the upper extremities, most frequently subungual areas. They can be either solitary or multiple. Most typically they present as a small, round, bluish nodule visible through the nail plate with a classic triad of symptoms: hypersensitivity to cold, heightened pinprick sensitivity, and paroxysmal pain. Several tests can help in diagnosing these tumors with multiple imaging tools such as X-ray, magnetic resonance imaging, and ultrasonography. However, only histology can confirm the diagnosis. Complete surgical excision of the tumor is the only effective treatment to achieve pain relief and low recurrence rate. CASE PRESENTATION: We report here a rare case of a 54-year-old Moroccan Berber woman presenting with a 10-year history of a glomus tumor at an unusual site. Dermoscopy and histology were helpful to confirm the diagnosis. CONCLUSIONS: We aim to discuss clinical, dermoscopical aspects of this tumor and surgical modalities. We also emphasize the importance of keeping this tumor in mind among the possibilities of differential diagnosis of painful digital nodules.

[Pityriasis lichenoides: not always a clear-cut diagnosis!] / Pithyriasis lichénoïde: diagnostic pas toujours aussi facile!

Pityriasis lichenoides is a rare inflammatory dermatosis occurring in young subjects. It evolves into rashes on the trunk and the limbs which regress spontaneously. We here report a particular case of pityriasis lichenoides whose diagnosis was adjusted due to the scar appearance of the lesions. The patient was treated with cyclin and phototherapy, with a favorable outcome.

[Localized scleroderma: about 24 cases]. / Sclérodermie localisée: à propos de 24 cas.

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.

Beyond classic dermoscopic patterns of dermatofibromas: a prospective research study.

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.

Dermoscopic Analysis of Nevus Sebaceus of Jadassohn: A Study of 13 Cases.

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.

Skin cancer knowledge and attitudes in the region of Fez, Morocco: a cross-sectional study.

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.

[The role of dermoscopy in the diagnosis of basosquamous carcinoma]. / L'apport de la dermoscopie dans le carcinome basosquameux.

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.
