Molluscum contagiosum chez un adulte immunocompétent : aspect clinique, dermoscopique et histologique (Molluscum contagiosum in an immunocompetent adult: clinical, dermoscopic and histological aspects)

Introduction: The virus that causes molluscum contagiosum is an important human skin disease agent. It is more common in children and immunocompromised people, and less common in immunocompetent adults. Observation: We report the case of a 25 year old patient who has presenting for the past 03 months, multiple, rounded, dome-shaped, pink, waxy papules that are 2-5 mm in diameter on the back and arm sides. The patient reported frequenting traditional Moroccan baths and the use of exfoliating bath gloves. Dermoscopy showed yellowish-white amorphous central polylobular patterns surrounded by vascular structures. These aspects were suggestive of the diagnosis of molluscum contagiosum. The blood test, including HIV serology was negative and histopathology confirmed the diagnosis. Management was based on electrocautery. Discussion: Even if the clinical diagnosis of molluscum contagiosum seems easy, the semiological presentations are very numerous. Dermoscopy therefore occupies a very important place. Conclusion: The occurrence of molluscum contagiosum in an adult should lead to a search for underlying immunosuppression, sexual relations or lifestyle habits. Dermoscopy remains an essential tool in the diagnosis.
