Comparison of two dermoscopic techniques in the diagnosis of clinically atypical pigmented skin lesions and melanoma: seven-point and three-point checklists.

Background: Over the past decade, many dermoscopic criteria and algorithmic methods have been developed for the early diagnosis of cutaneous melanoma.

Objective: To compare the sensitivity, specificity, and diagnostic accuracy of the seven-point and three-point checklist methods in a series of dermoscopic images. The diagnostic value of dermoscopic criteria was also determined on the basis of their frequency.

Monosymptomatic hypochondriacal psychosis presenting with recurrent oral mucosal ulcers and multiple skin lesions responding to olanzapine treatment.

Monosymptomatic hypochondriacal psychosis (MHP) is a form of psychosis characterized by the delusional idea that there is a serious problem in the skin or other body parts. Because MHP patients believe that their complaint is dermatological, not psychiatric, they often admit to several other medical disciplines before coming to a psychiatry clinic. This leads to a series of time-consuming examinations and treatment interventions.
