Background: Psoriasis is a chronic, inflammatory, and recurrent dermatological disease. In the Côte d'Ivoire, it is about 0.75% of dermatology cases. Psoriasis care is challenging in elderly patients. We aimed to show its specificities related to the sociodemographic, clinical, and therapeutic aspects, and follow-up in geriatric patients., Methods: Cross-sectional and descriptive study over a period of 10 years (January 2004-December 2013)., Results: The prevalence of patients 60 years of age and older was about 0.1% (47 of 46,623 cases). The average age was 67 ± 1 years ranging from 60 to 85 years. The sex ratio was 1 : 9 in favor of men. The average time course of psoriasis was 25 ± 2 months. Comorbidity was found in 27 cases (57.5%). The most observed type of psoriasis in our study was chronic plaque psoriasis in 51.1% of cases. We found severe cases of psoriasis in 25.5% of cases. More than 10% of the body surface area was affected in 27.6% of cases. We used topical treatments in the majority of cases (83%). The course of psoriasis under treatment was good in 63.8% of cases, and only 6.4% of cases were worsening., Conclusion: Topical agents could be the first-line treatment in geriatric patients in poor countries. If necessary, systemic agents should be used by taking into account the severity of psoriasis, presence of comorbidity factors, immune system level, and lifestyle., (© 2015 The International Society of Dermatology.)

Background: Buruli ulcer is an infection caused by Mycobacterium ulcerans occurring in tropical areas. In West Africa, it is an emerging threat mainly affecting children aged under 15years. This chronic disease is complicated by dystrophic scars in which squamous cell carcinoma can occur in the long term., Patients and Methods: This is a retrospective study of squamous cell carcinomas in Buruli ulcer scars seen at the Treichville University Hospital (Abidjan, Ivory Coast) over a five-year period., Results: During the study period, 8cases were observed and concerned young adults presenting Buruli ulcer in their childhood. Tumours were restricted to the limbs, with loco-regional invasion. Treatment was primarily surgical. Four of the patients died., Discussion: The risk of recurrence of cancer in these scars remains poorly evaluated, highlighting the importance of long-term monitoring strategies for human patients in order to ensure rapid identification of any changes in Buruli ulcer scars., (Copyright © 2015 Elsevier Masson SAS.
