Lip Reconstruction After Mohs Micrographic Surgery: A Guide on Flaps.

The lips are commonly affected by skin cancer because of increased sun exposure over time. Even with early detection, many of these skin cancers require surgical removal with subsequent reconstruction. Mohs micrographic surgery is the preferred method of treatment for nonmelanoma skin cancers of the lip, as it has the lowest recurrence rates and allows for the maximum preservation of healthy tissue. After surgery, the remaining lip defect often requires reconstruction with skin grafts or a local cutaneous or myocutaneous flap. There are several local flap reconstruction options available, and some may be used in combination for more complex defects. We provide a succinct review of commonly utilized flaps and outline their indications, risks, and benefits.

Aquatic Antagonists: Marine Rashes (Seabather's Eruption and Diver's Dermatitis).

When treating marine rashes, it is imperative to properly diagnose the root cause to guide appropriate treatment. Two of the most common rashes experienced after ocean contact are known colloquially as seabather's eruption and diver's dermatitis. In many cases, a thorough history and physical examination can aid in elucidating the responsible organism. Understanding the etiology of rashes obtained in marine environments can improve patient education on precautionary measures that can be taken to avoid exposure. Reasons for further research in this area include development of more effective treatments, as current therapies are limited to symptom management.

Impact of the COVID-19 Pandemic on Characteristics of Cutaneous Tumors Treated by Mohs Micrographic Surgery.

The COVID-19 pandemic has impacted the practice of Mohs micrographic surgery (MMS). We sought to determine the characteristics of skin cancers treated by MMS during the pandemic compared with prepandemic controls. A retrospective chart review was conducted. Tumors included were all treated in accordance with best practice guidelines set forth by state- and national-level professional governing bodies. Bivariate and multivariate analyses were performed to compare outcome variables. Changes in tumor characteristics during the pandemic are of clinical significance, potentially affecting extent of reconstructive surgery, cost, operating time, and future tumor characteristics.

Cutaneous nontuberculous mycobacteria infections: A retrospective case series of 78 patients from the Texas Gulf Coast region.

BACKGROUND: The incidence of cutaneous nontuberculous mycobacteria (NTM) infections is increasing. These infections are a diagnostic and therapeutic challenge. OBJECTIVE: We investigated the clinical features, diagnosis, and management of cutaneous NTM infections. METHODS: A retrospective case series studied 78 patients from a Gulf Coast tertiary referral center diagnosed with cutaneous NTM infection by culture or stain of a skin biopsy specimen. RESULTS: A history of trauma, procedure, or environmental exposure was common. The mean time between the initial evaluation and diagnosis was 12 weeks. Only 15% of acid-fast bacillus-positive cultures had a positive acid-fast bacillus smear, and only 43% of those accompanied by skin biopsy specimen had a positive Fite stain. Immunosuppressed patients were more likely to have a positive Fite stain. Treatment included surgery and multiple antibiotics. Immunosuppressed patients and Mycobacterium abscessus group infections were more likely to have persistent disease. LIMITATIONS: M chelonae and M abscessus isolates were indistinguishable and therefore were reported together. Five cases were not confirmed by culture. CONCLUSIONS: Even with clinical suspicion, the diagnosis of NTM infection can be difficult. Results of acid-fast bacillus smears and special stains are frequently negative. Antibiotic resistance is common. Multidrug treatment is often required, and surgical therapy may be needed.
