Background: Dermatological manifestations are frequent and often constitute a circumstance of HIV discovery in 70% of cases [1]. They are observed in 83% of patients with AIDS and at an early stage in 75% [2,3,4,5]. The objective of this study was to describe the epidemiological, clinical, therapeutic, and evolutionary aspects of skin manifestations during HIV infection in children. Materials and Methods: We conducted a cross-sectional, multicentric, descriptive study over a period of ten years in two dermatology departments and one pediatric department in Dakar, Senegal. We included all HIV-seropositive children aged 0–15 years with mucosal cutaneous manifestations. A dermatologist and a specialist in the medical care of HIV performed the diagnosis of cutaneous manifestations. Data entry and analysis were performed with the SPSS software, version 9.05. Results: We collected 206 cases of cutaneous manifestations in 454 children followed for HIV infection. The hospital frequency was 45.3%. The children were male in 115 cases (55.83%) and female in 91 cases (44.17%), giving a sex ratio of 1.26. The mean age of the patients was sixty months, with extremes of one month to fourteen years. A mycotic dermatosis origin was noted in 47.37%, ringworm in 22.37%, dermatophytosis in 8.58%, oral candidiasis in 6.58%, seborrheic dermatitis in 6.58%, and perleche in 3.29%. Bacterial skin diseases were represented by furunculosis in 1.97%, and impetigo in 7.24%. Viral dermatoses included molluscum contagiosum in 10.53%, shingles in 9.21%, warts in 9.87%, and chickenpox in 3.95%. As for parasitic dermatoses, scabies was noted in 8.55, followed by larva migrans in 0.66% and cutaneous leishmaniosis in 0.66%. Immuno-allergic dermatoses accounted for 25% and included prurigo in 94.3%, atopic dermatitis in 1.90%, and fixed pigmented erythema in 1.90%. Conclusion: Cutaneous manifestations are a common discovery during HIV infection in children. They are marked by a predominance of infectious dermatoses in sub-Saharan Africa.

Introduction: The general objective was to determine the epidemiological, clinical, paraclinical, therapeutic and evolutionary aspects of connectivitis in the dermatology department of the CHU Aristide Le Dantec. Patients and methods: This was a retrospective and descriptive study conducted in the Dermatology Department of the University Hospital Center (UHC) Aristide Le Dantec (HALD) of Dakar between January 2009 and December 2019. Their diagnoses were retained according to the international criteria validated in the course of connectivites Results: We identified 290 cases of connectivitis. Systemic scleroderma was the most frequent in 34.42% (n=94), followed by systemic lupus in 25.86% (n=75), mixed connectivities in 22,06% (n=64) and dermatomyositis in 19,32% (n=56). Cancer was associated with dermatomyositis in 11 cases and with systemic scleroderma in 3 cases. The mean age of our patients was 38.23 years. The sex ratio was 4.2 and the mean duration of evolution was 25 months. Dermatological manifestations were constant, found in all patients. In systemic lupus, they were dominated by discoid lupus lesions found in 40% and hypochromic spots (86%) in systemic scleroderma. In dermatomyositis, skin lesions were dominated by periorbital erythroedema (66.07%). Joint manifestations were found in 56.89% of cases (n= 165), muscular manifestations in 41.37% of cases (n= 120) and pleuropulmonary manifestations in 31.3% of cases (n=91). Neuropsychiatric manifestations were noted in 5.17% of cases (n=15). All our patients were treated with corticosteroid therapy and 12.06% of them had received immunosuppressive treatment, the most commonly used molecules being methotrexate (3.44%) and cyclophosphamide (8.27%). Hydroxychloroquine was prescribed in 59.31% of patients, while D-penicillamine was prescribed in 42.06% of patients, 100% of whom were treated for systemic scleroderma. The main complications encountered were infectious complications in 83 cases (28.6%). Visceral complications, a type of visceral insufficiency, were noted in 4.13% of cases. Conclusion: Our study demonstrates the frequency of connectivitis in the dermatology department. Its particularity was the predominance of systemic scleroderma over lupus which was classically the first connectivite in dermatology services. The delay in diagnosis noted is correlated with visceral attacks; hence the importance of a better knowledge of these affections for an early management.

Subcutaneous or furunculoid myiasis is an ectoparasitosis caused by the cutaneous or subcutaneous carriage of larvae of various diptera. The causal agent is most often Cordylobia Anthropophaga in tropical areas. We report an observation of multiple subcutaneous myiasis in an infant. The toddler was 2 months old, with no previous history of myiasis and was up to date with vaccinations. He was treated for furunculoid lesions evolving for 5 days. The dermatological examination revealed three inflammatory nodules centred by a whitish orifice without fluid discharge, located on the thorax, the back and the buttocks. The rest of the clinical examination was unremarkable. A maggot was extracted by bi-digital compression of a nodule in the thorax. The diagnosis of furunculoid myiasis was set. The treatment consisted of manual extraction of the maggots and local care. The evolution was favourable after two weeks, labelled by a complete healing of the lesions. Our case is particular because of the occurrence of subcutaneous myiasis in an infant and its misleading clinical presentation simulating multiple furuncles.
