Fifteen years ago the US Food and Drug Administration approved the use of photodynamic therapy (PDT) in dermatology for the treatment of actinic keratosis (AK). Photodynamic therapy using topical agents in combination with visible light has been investigated extensively with a general consensus that in cutaneous oncology, PDT is probably ...

Importance  Photodynamic therapy (PDT) is used extensively to treat actinic keratoses (AKs). An analysis of the effectiveness of PDT compared with other treatments may help physicians decide what role it should play in their own clinical practices.

Objective  To determine the effectiveness of PDT for the ...

Importance  Previous studies have reported that histopathologically amelanotic melanoma is associated with poorer survival than pigmented melanoma; however, small numbers of amelanotic melanomas, selected populations, lack of centralized pathologic review, or no adjustment for stage limit the interpretation or generalization of results from prior studies.

Objective  ...

Importance  Eruptive melanocytic nevi (EMN) are characterized by the sudden onset of numerous melanocytic nevi and have been traditionally described in the setting of immunosuppression. Selective BRAF inhibitors, such as vemurafenib cause multiple cutaneous adverse effects, including the formation of cutaneous squamous cell carcinoma, as well as ...

Reason dictates that rapidly growing melanomas carry a worse prognosis than those that are quiescent. Indeed, much focus has been given to calculating the growth index of melanomas as defined by their mitotic rate1,2—a process that requires counting the number of mitoses in several high-power fields. As expected, mitotic rate ...

We have all experienced the patient with red legs, referred for refractory “cellulitis” not responding to systemic antibiotics. Primary care, urgent care, hospitalist, and emergency department physicians are on the front line seeing these patients; however, they often lack the training that allows them to recognize cellulitis mimickers. This constitutes ...

Importance  Mitotic rate is now recognized as having independent prognostic significance in melanoma survival. However, its clinicopathologic associations have not been the focus of any previous study.

Objective  To identify a set of patient and tumor characteristics associated with high-mitotic-rate melanoma with the aim of facilitating ...

Importance  Cellulitis is a common and costly problem, often diagnosed in the outpatient setting. Many cutaneous conditions may clinically mimic cellulitis, but little research has been done to assess the magnitude of the problem.

Objective  To determine if obtaining dermatology consultations in the outpatient primary care ...

Importance  Acquired cutis laxa is a rare cutaneous manifestation of hematologic malignancy. We report a case of γ heavy chain deposition disease (HCDD) associated with acquired cutis laxa, renal involvement, and hypocomplementemia and propose a mechanism of elastic fiber degradation in the skin of this patient with ...

Importance  B-cell depletion with the anti-CD20 antibody rituximab is highly effective for pemphigus vulgaris (PV) treatment. However, most patients experience relapse, and intravenous rituximab infusions are expensive. Therefore, cost-effective anti-CD20 therapies are desirable.

Observations  A compassionate-use investigational new drug protocol was approved to administer veltuzumab, a ...

Viewpoint 
Joseph C. Pierson, MD
Shortly after I began prescribing certain topical medications in the early 1990s, I started to question the ritual. That universal thrill new clinicians experience when confidently knowing the diagnosis and its treatment was soon tempered by the realization that many patients had arrived already knowing both, and they resented a ...

Since the passing of the Congressional Balanced Budget Act in 1997,1 the scope of practice of mid-level health care providers, namely nurse practitioners and physician assistants (hereinafter “mid-level providers”), has rapidly expanded. While originally envisioned to improve access to primary care in underserved areas under the supervision of a physician, ...
