Background: Early detection of melanoma constitutes a major challenge and is a common reason for dermatological consultations. There is no recent data on melanomas diagnosed in the private medical sector in France, nor on the circumstances of diagnosis.
Patients And Methods: This was a retrospective observational study on records collating data on all new consecutive cases of melanoma diagnosed between January 2015 and June 2018, in the private sector only, by volunteer dermatologists belonging to the association for continuing medical education, "Dermatologie Paris XV".
Background: Acral lesions, mainly chilblains, are the most frequently reported cutaneous lesions associated with COVID-19. In more than 80% of patients tested, nasopharyngeal swabs were negative on reverse transcription polymerase chain reaction (RT-PCR) for SARS-CoV-2 when performed, and serology was generally not performed.
Methods: A national survey was launched on 30 March 2020 by the French Society of Dermatology asking physicians to report cases of skin manifestations in patients with suspected or confirmed COVID-19 by using a standardized questionnaire.
Background: Pityriasis versicolor (tinea versicolor) is a common skin disorder due to Malassezia usually affecting adolescents and young adults, more frequently in the tropics. Facial involvement, isolated or not, is not frequent in white adults.
Objective: Here, we report a possible atypical hyperkeratotic form of dermatosis of the face, in two young immunocompetent Caucasian patients, particularly recalcitrant to therapy.
