Macrophages in dermatology: pathogenic roles and targeted therapeutics.

The field of macrophage biology is rapidly growing. Recent studies have shifted focus from classic wound healing roles to newly identified roles in dermatologic pathology. These studies have identified pathogenic roles of macrophages in relatively common conditions, such as psoriasis, skin cancer, and cutaneous T-cell lymphoma.

Laser safety: the need for protocols.

Lasers are being used in ever-expanding roles in dermatology. As our understanding of laser energy grew, the need for safety guidelines became apparent. The US Food and Drug Administration (FDA) published the first safety guidelines in 1984, which are updated on a regular basis.

Assessment of Functionality in Elderly Patients When Determining Appropriate Treatment for Nonmelanoma Skin Cancers.

Background: The treatment of nonmelanoma skin cancer (NMSC) in the elderly population is a source of significant debate. Mohs micrographic surgery (MMS) is a highly effective treatment option yet not every patient with a cutaneous malignancy that meets appropriate use criteria (AUC) should be treated with surgery.

Objective: The purpose of this study was to use the Karnofsky Performance Status (KPS) scale to categorize the functional status of patients aged 75 years and older who required treatment of NMSC.

Strategic mentoring: growth for mentor and mentee.

Mentoring is enriching for both the mentor and mentee, but often getting started can be a primary obstacle to this useful tool. This contribution focuses on how to embark on a mentoring relationship with a junior colleague. In addition to describing various approaches to being a mentor, it outlines unproductive traps to avoid, steps to establishing a successful mentoring relationship, including conversation starters, and professional skills one can continue to develop to improve mentoring outcomes.

Composite lymphoma of mycosis fungoides and cutaneous small B-cell lymphoma in a 73-year-old male patient.

Composite lymphoma of T-cell and B-cell type is uncommon, and the one occurring primarily on skin is extremely rare. Herein, we report a unique case of composite lymphoma of mycosis fungoides and cutaneous small B-cell lymphoma in a 73-year-old male patient. The patient presented with multiple erythematous patches, plaques, and nodules on the upper arms, scalp, and trunk.

AAD/ACMS/ASDSA/ASMS 2012 appropriate use criteria for Mohs micrographic surgery: a report of the American Academy of Dermatology, American College of Mohs Surgery, American Society for Dermatologic Surgery Association, and the American Society for Mohs Surgery.

The appropriate use criteria process synthesizes evidence-based medicine, clinical practice experience, and expert judgment. The American Academy of Dermatology in collaboration with the American College of Mohs Surgery, the American Society for Dermatologic Surgery Association, and the American Society for Mohs Surgery has developed appropriate use criteria for 270 scenarios for which Mohs micrographic surgery (MMS) is frequently considered based on tumor and patient characteristics. This document reflects the rating of appropriateness of MMS for each of these clinical scenarios by a ratings panel in a process based on the appropriateness method developed by the RAND Corp (Santa Monica, CA)/University of California-Los Angeles (RAND/UCLA).

Clinical case of the month. A young man with a persistent skin eruption. Mycosis fungoides.

There are many types of skin disease that fit into the classification of cutaneous lymphoma, but mycosis fungoides is by far the most common of this group. It is a non-Hodgkin's lymphoma of T-cell origin that presents in the skin. Mycosis fungoides often evolves for years without a specific diagnosis because it can present as an eczematous or psoriasiform eruption.

Cutaneous T-cell lymphoma in a patient with neurofibromatosis type 1.

A variety of neoplasms may occur in association with neurofibromatosis type 1 (NF1). We describe a patient with NF1 and mycosis fungoides. Recommendations for the initial and long-term evaluations of patients with neurofibromatosis are presented.

CD20-negative relapse of cutaneous B-cell lymphoma after anti-CD20 monoclonal antibody therapy.

Despite cutaneous B-cell lymphoma often having a relatively indolent course and low mortality, it is often resistant to conventional therapy and frequently relapses. We describe a patient with widespread cutaneous B-cell lymphoma who was treated successfully with a recently approved chimeric monoclonal antibody directed against the CD20 antigen (rituximab) and the CD20-negative relapse that resulted.

Side effects and complications of laser therapy.

Laser skin surgery is not without risk and some degree of downtime in most situations. Patient satisfaction is key to the perceived success of the procedure. Therefore, the physician must fully explain all risks, potential complications, and expected morbidity associated with any laser treatment to be performed.
