Myxofibrosarcoma-Like Spindle Cell Squamous Cell Carcinoma of the Scalp: A Rare Mimic.

We report a challenging case of a man in his mid-70s diagnosed with a myxofibrosarcoma-like spindle cell squamous cell carcinoma (ML-SCC) on the scalp. This rare tumor shares cytologic features with spindle cell squamous cell carcinoma (SCC) with myxoid characteristics but also exhibits architectural elements typical of myxofibrosarcoma, making it nearly indistinguishable by routine light microscopic evaluation. Myxoid spindle cell carcinomas are exceptionally rare, and only one case of ML-SCC has been previously documented in the peer-reviewed medical literature.

Public Interest in a Potentially Harmful, Non-Evidence-Based "Wellness" Practice: Cross-Sectional Analysis of Perineum Sunning.

Background: Perineum sunning/tanning is a potentially harmful yet popular new health trend cultivated by a viral social media post, famous public figures, and subsequent media coverage.

Objective: Our primary objective is to evaluate public interest in perineum sunning/tanning.

Methods: Using an observational study design, we extracted data from Google Trends for the terms "perineum sunning," "perineum tanning," "Metaphysical Meagan," and "Josh Brolin"; and Twitter (via SproutSocial) for "perineum sunning" and "perineum tanning" from November 1, 2019, to December 31, 2019.

Lifestyle behaviors and sun exposure among individuals diagnosed with skin cancer: a cross-sectional analysis of 2018 BRFSS data.

Purpose: With the continued increase in skin cancer incidence rates, the population of skin cancer survivors continues to grow. Understanding skin cancer survivors' lifestyle behaviors, including ultraviolet radiation exposure, is important in reducing skin cancer recurrences and improving health outcomes. The objective of this study is to compare the differences in lifestyle behaviors among skin cancer survivors or individuals who currently have skin cancer versus individuals who have never had a skin cancer diagnosis.

Activation of the mesostriatal reward pathway with exposure to ultraviolet radiation (UVR) vs. sham UVR in frequent tanners: a pilot study.

Frequent and excessive tanning persists despite a growing understanding of its associated morbidity and mortality, suggesting that ultraviolet radiation may impart rewarding effects beyond the assumed cosmetic benefits. To empirically measure putative centrally rewarding properties of ultraviolet radiation (UVR), we assessed the effects of a commercially available tanning bed upon regional cerebral blood flow (rCBF), a measure of brain activity, using single-photon emission computed tomography (SPECT). Seven frequent salon bed tanners were placed under a UVA/UVB tanning light during two sessions; one session with UVR and the other with filtered UVR (sham UVR).
