This narrative review reports that IL-17 and IL-23 inhibitors, while effective for psoriasis and other inflammatory diseases, can cause a variety of skin reactions that resemble primary dermatoses, highlighting the need for careful diagnosis and varied management strategies.

In this study, alopecia areata patients treated with diphencyprone showed a significant increase in CD8 lymphocytes around hair bulbs, which may be associated with hair regrowth.

This abstract highlights that alopecia treatment requires moving beyond outdated methods to a sophisticated approach that considers the complex interplay between genetic susceptibility and immune response in different types of hair loss. Results are not reported.

This review provides a framework for diagnosing acquired scalp alopecias and discusses both non-scarring and scarring types, but reports no new clinical results.

Stopping sunscreen use on the forehead led to hair regrowth in a woman with frontal fibrosing alopecia.

The conclusion is that different types of hair loss in dogs and cats can be cosmetic or serious, and affected animals should not be bred.

This review discusses the use of phototherapy for treating different types of alopecia and reports its potential effectiveness without serious adverse reactions, but it emphasizes the need for further studies to optimize treatment parameters.

This study describes a form of lymphocytic mural folliculitis in tigers causing hair loss, concluding it may represent a nonspecific hypersensitivity reaction distinct from T-cell lymphoma.

This study reviews the diverse clinical presentations of tinea capitis, such as gray patches, a "black dot" appearance, and kerion, highlighting its complex differential diagnosis with conditions like alopecia areata and psoriasis.

This article discusses the role of inflammation in causing various types of alopecia but reports no clinical results; the author notes an ongoing interest in the topic.

This article discusses folliculitis decalvans as a cicatricial alopecia caused by a neutrophilic immune reaction to microbial biofilms, but it reports no new clinical results.

This study observed that a targetoid polycyclic concentric hair regrowth pattern appeared in some male patients with alopecia areata following treatment, indicating a positive sign of recovery despite unclear etiopathogenesis.

This review discusses various skin diseases with endocrinological origins and reports no clinical results, highlighting the need for interdisciplinary understanding in diagnosis.

A man's red tattoo caused a skin reaction and hair loss in his beard, which improved after treatment.

This review discusses the range of cutaneous immune-related adverse events induced by immune checkpoint inhibitors and the proposed mechanisms underlying these skin reactions, but reports no new clinical results.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

In this study, researchers identified a specific T cell receptor associated with carbamazepine-induced severe cutaneous adverse reactions, demonstrating its potential for therapeutic development in patients with the HLA-B*15:02 genotype.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.

This review found that adding immune checkpoint inhibitors to cancer treatment regimens likely increases the incidence of specific drug-related skin toxicities in adult Asian patients, highlighting the need for careful monitoring and management strategies.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.
