“…In our series, we noted a predominance of females, in opposite to studies carried out in Madagascar and Ivory Coast [12,14], and a predominance of males in France [11]. In our study, we noted an average delay in diagnosis of 20 months; this delay in specialist consultation is also observed in Burkina Faso, with an average delay of 13.4 months [19]. The reason seems to be the patient's therapeutic itinerary, self-medication and difficulties in accessing specialized care.…”

Introduction: Cutaneous squamous cell carcinoma (SCC) is rare in sub-Saharan Africa. In Senegal, its prevalence was estimated at 0.09% in 2004. It occurs most frequently in pre-neoplastic acquired or genetic dermatoses. The aims of this study were to describe the epidemiological, clinical and therapeutic aspects of SCC, and to identify associated risk factors. Methodology: This was a descriptive cross-sectional study in the Oncology Department at the Joliot Curie Institute of the Aristide Le Dantec Hospital over a 7-year period (January 2015 to December 2021). We included all patients hospitalized and followed up for SCC. The diagnosis was confirmed by histopathology. Data entry and analysis were performed using epi-info software version 7.2.5.0 and Excel 365. Results: We recorded 189 cases of SCC, representing an incidence of 24 cases per year and a hospital frequency of 0.77%. The mean age was 51 and the sex ratio 1.28. The ulcero-budding form was predominant in 67.2% of cases. The majority of lesions were located on the lower limbs (30.6%) and 28.4% on the cephalic extremity. Squamous cell carcinoma was well-differentiated in 49.2%. Metastases were present in 40.2%. Pre-neoplastic dermatoses were noted in 28.6%. These were burn scars in 43%, chronic ulcer in 23.39%, discoid lupus in 2%, Buschke Lowenstein tumor in 4%. Geno dermatoses included albinism in 6 cases and xeroderma pigmentosum in one. Voluntary use of depigmenting cosmetics was noted in 11 cases. Patients underwent surgery in 32.3%, radiotherapy in 8.5% and chemotherapy in 32.8%. Favorable progression was in 20.6%. Recurrence was noted in 2 cases, metastasis in 3 and death in 5. Conclusion: Squamous cell carcinoma remains a serious tumor in Africa. There is a delay in diagnosis, with some tumors being very advanced. Early surgical management is the main factor in curing the cancer.

Spectrum of skin diseases in Maroon villages of the Maroni area, French Guiana

et al. 2022

Background Due to their genetic characteristics and their high exposure to infectious diseases, Maroons are likely to suffer from a specific spectrum of skin diseases. However, skin disorders have never been explored in this population. We aimed to describe all skin diseases in Maroon villages of the Maroni region in French Guiana. Methods This retrospective study concerned all patients who consulted in the remote health centers of Apatou, Grand‐Santi, Papaichton, and Maripasoula between October 5, 2017, and June 30, 2020. We included all patients registered with a skin disorder (International Classification of Diseases) in the medical database. We excluded patients whose diagnosis was invalidated after cross‐checking by a dermatologist. Results A total of 4741 patients presented at least one skin disease, for 6058 different disorders. Nonsexually transmitted infections represented 71.6% of all diagnoses, followed by inflammatory diseases (9.8%) and bites/envenomations (4.6%). The three most frequent conditions were scabies, abscesses, and impetigo. Besides scabies, neglected tropical diseases (NTDs) were still prevalent as we reported 13 cases of leprosy and 63 cutaneous leishmaniasis. Atopic dermatitis (AD) represented only 2.5% of our diagnoses. Conclusions With the exception of AD, which was less frequent among Maroons, these results are similar to those previously reported in Amerindians. Therefore, a common exposure to rainforest pathogens seems to induce a common spectrum of skin diseases dominated by infections. The high prevalence of NTDs requires specific public health actions.
