Dermoscopy image-based self-learning on computer improves diagnostic performance of medical students compared with classroom-style lecture in ultra-short period.

The educational effectiveness of dermoscopy image-based self-learning on a computer for medical students has not been well examined. To assess the effect of an image-based self-learning session on the dermoscopic diagnostic performance for malignant melanoma (MM), basal cell carcinoma, melanocytic nevus and seborrheic keratosis (SK) on non-acral regions in comparison with a conventional classroom-style lecture, 114 fourth-year medical students (mean age, 23.7 years; male : female, 73:41) were enrolled.

Clinical and Histopathologic Characteristics of Melanocytic Lesions on the Volar Skin Without Typical Dermoscopic Patterns.

Importance: It is challenging to differentiate melanoma from melanocytic nevus on the volar skin in the absence of typical dermoscopic patterns.

Objective: To identify the frequency and clinical and dermoscopic characteristics of melanocytic lesions on the volar skin not displaying a parallel furrow pattern, lattice-like pattern, fibrillar pattern, or parallel ridge pattern on results of dermoscopy.

Design, Setting, And Participants: In this retrospective cohort study, a total of 504 melanocytic lesions on the volar skin were evaluated in the Shinshu University Hospital department of dermatology between January 1, 2000, and December 31, 2012.

Nivolumab-induced organizing pneumonia in a melanoma patient.

We report the case of a 70-year-old woman with vaginal melanoma and multiple metastases in the lung. After the third dose of nivolumab, decreased room-air resting arterial oxygen saturation with bilateral basal fine crackles on auscultation developed despite the absence of respiratory symptoms. Computed tomography showed ground-glass opacities with airspace consolidations scattered with a peculiar distribution, and most were observed around the existing metastatic tumors in the lung.
