Response to Laser Treatment of Café au Lait Macules Based on Morphologic Features.

Importance: Response to laser treatment for café au lait macules (CALMs) is inconsistent and difficult to predict.

Objective: To test the hypothesis that irregularly bordered CALMs of the "coast of Maine" subtype respond better to treatment than those of the smooth-bordered "coast of California" subtype.

Design, Setting, And Participants: This retrospective case series included patients from 2 multiple-clinician US practices treated from 2005 through 2016.

A Prospective Study of Axillary Hair Reduction in Patients Treated With Microwave Technology.

Background: Removing unwanted body hair is a growing trend in society today, and there are many laser-based devices for hair reduction. There are some limitations to those methods, including the lack of efficacy for lighter color hair.

Objective: The objective was to quantify hair reduction in the axillae after treatment with a noninvasive microwave energy device.

Clinical and Histologic Features of Lichenoid Mucocutaneous Eruptions Due to Anti-Programmed Cell Death 1 and Anti-Programmed Cell Death Ligand 1 Immunotherapy.

Importance: Antagonist antibodies to programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) have shown remarkable activity in multiple tumor types. Recent US Food and Drug Administration approval of such agents for advanced melanoma, non-small cell lung cancer, and renal cell carcinoma has hastened the need to better characterize their unique toxicity profiles.

Objective: To provide a clinical and pathologic description of the lichenoid mucocutaneous adverse effects seen in patients receiving anti-PD-1/PD-L1 treatment.
