This review discusses the various skin lesions associated with COVID-19, which vary in type and severity, and reports that these lesions can appear before other symptoms and typically resolve spontaneously.

This article reviews historical and recent developments related to toxic shock syndrome (TSS), emphasizing the increase in cases among young women using tampons, and calls for new research tools but does not report new results.

This review found that infliximab, golimumab, and some forms of radiotherapy significantly improved nail psoriasis compared to controls, although they could have serious adverse effects and are not commonly used specifically for nail issues.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study reports on eight previously unpublished cases of Bohring-Opitz syndrome with ASXL1 mutations, suggesting the importance of screening for Wilms tumors in these patients.

Burn reconstruction improves with new techniques, materials, and tissue engineering.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.

This review discusses the variety of skin conditions linked to eating disorders and emphasizes that resolving these skin issues often requires treating the underlying disorder.

This review discusses various rare syndromes associated with ichthyosis and emphasizes the importance of understanding their molecular genetics and mechanisms for developing effective treatments and genetic counseling, but it reports no new clinical findings.

This article reviews fetal scalp hair formation and related disorders but reports no new research results.

This review describes the approved use and adverse effects of gefitinib in patients with advanced non-small cell lung cancer, without presenting new clinical findings.

This article reviews the expanding role of dermatologic ultrasonography in patient management for various skin conditions, highlighting its advantages over other imaging techniques, but reports no new findings.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

This review discusses the skin conditions linked to eating disorders and emphasizes that treating the underlying disorder often improves these dermatological symptoms.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study reported that the most common skin side effect of epidermal growth factor receptor inhibitors was a papulopustular rash, treatable with symptom-targeted therapies, while drug suspension was rarely needed.
