Paring is useful for both diagnosis and treatment of plantar warts. Paring techniques generally involve scalpel blades, abrasive tools, or curettes. However, these tools do not permit the use of an “awl-like” carving technique of the wart afforded by using a punch biopsy tool. We have found this technique to be associated with greater precision and safety, as well as potentially increased efficacy compared to traditional methods.

Syphilis is commonly known as “the great imitator” owing to its varied clinical manifestations. Secondary syphilis has a variety of presentations, with the most common manifesting as a diffuse papulosquamous eruption on the palms and soles. Lues maligna praecox is a rare form of secondary syphilis, with severe constitutional symptoms, seen primarily in HIV-positive individuals. We report an atypical case of suspected lues maligna in a 45-year-old male. The patient was HIV-positive with a CD4 count of 441. He presented to our clinic with large painful gummatous ulcers in the groin and lower back. He also reported daily fevers, night sweats, and weight loss consistent with secondary syphilis. Prior to this episode the patient had a history of acute active syphilis (RPR 1:128) in 2012 treated at that time with a single dose of 2.4 million units intramuscular benzathine penicillin; he had no reported exposures since that time. The patient was treated with three weekly doses of benzathine penicillin, 2.4 million units, given intramuscularly. This case demonstrates the importance of recognizing the varied clinical presentation of secondary syphilis and keeping lues maligna in consideration for ulceronodular skin lesions in patients who are HIV-positive.

Current healthcare trends promote data-driven “benchmarking” to decrease cost and increase quality. Dermatologists perform 79% of skin biopsies and biopsy rate is an easily measured benchmark. To reduce the risk of a misguided “one size fits all” benchmark for biopsies, it will help to document the factors driving divergent biopsy rates.

This letter compares biopsy rates and high-risk patient ratios for 1000 sequential patients from two academic dermatologists. Elevated biopsy rates (0.55 vs 0.42, p < 0.001) were associated with elevated ratios of high-risk patients (.52 versus .30, p< 0.001). Although limited by small sample size, this research takes a first step toward future efforts to improve accuracy of biopsy benchmarking.
