Black salve and bloodroot extract in dermatologic conditions.

Due to extensive advertising of black salve's effectiveness in "curing" skin cancers and healing other skin conditions, many patients are turning to self-treating with black salve. Although black salve has not been proven to have anticancer properties, application of black salve has been shown to cause damage to healthy tissue and the need for further treatment. We describe a 35-year-old woman whose one-time application of black salve to a healing biopsy site resulted in skin erosion and formation of a dermatitic plaque with subsequent scarring.

Five-year outcomes of wide excision and Mohs micrographic surgery for primary lentigo maligna in an academic practice cohort.

Background: Wide local excision with 5-mm margins is the standard of care for lentigo maligna (LM). Mohs micrographic surgery (MMS) is used increasingly to treat this tumor.

Objective: To study the authors' experience with these 2 approaches.

Characteristics of sebaceous carcinoma and early outcomes of treatment using Mohs micrographic surgery versus wide local excision: an update of the Mayo Clinic experience over the past 2 decades.

Background: Sebaceous carcinoma (SC) is a rare cutaneous neoplasm.

Objective: To characterize SC and treatment approaches and outcomes.

Methods And Materials: We retrospectively reviewed records of patients with SC from 1992 through 2012.

Incidence of lentigo maligna in Olmsted County, Minnesota, 1970 to 2007.

Background: The incidence of lentigo maligna (LM) may be increasing, but no population-based epidemiologic studies have been performed to our knowledge.

Objective: We sought to determine the incidence of LM in Olmsted County, Minnesota, along with overall and recurrence-free survival.

Methods: Using the Rochester Epidemiology Project, we identified all adult residents of Olmsted County, Minnesota, with a first lifetime diagnosis of LM between 1970 and 2007.
