This review highlights the challenges in identifying histological features of adverse reactions to soft tissue fillers and emphasizes the need for increased awareness due to product uncertainty and delayed reactions.

Eating shiitake mushrooms caused a man to develop a rash similar to a skin condition known as AGEP.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

Minoxidil can help grow hair and make hair follicles bigger, but it can also cause side effects.

This study suggests that hairless dogs' skin shows sensitivity to topical corticosteroids, highlighting their potential as a model for studying the efficacy and adverse effects of these treatments on skin.

This article provides a comprehensive overview of tattoo-related issues for clinicians, covering various aspects such as tattoo types, medical relevance, removal methods, complications, and South African legislation, but reports no new research findings.

In this study, the authors found that rabbit hair material ground for 8 hours had better suitability and histocompatibility for injectable soft tissue augmentation compared to other tested formulations.

This study found that human hair keratin artificial tendons have low antigenity and may serve as an effective substitute for tendon repair in the upper extremities.

This study describes "alarm reaction" histologic changes in pilosebaceous structures, including regression of hair matrix and alterations in sebaceous glands, affecting follicular and sebaceous gland morphology.

In this study, the authors observed that a 48-year-old woman developed a cutaneous pseudolymphoma in the earlobes linked to metallic debris from ear piercing, which histologically mimicked lymphoma but was interpreted as a reactive condition.

In this study, human-hair artificial tendon material showed good biocompatibility and variable degradation rates in rabbits, depending on treatment time, with minimal inflammatory reactions observed.

This study established a murine model for radiation-induced skin reactions, replicating clinical and histological features to aid future mechanistic and therapeutic research.

This study found that monoclonal antibodies can identify specific immunological characteristics of hair fibrous proteins, with some antibodies reacting only with hair proteins and others showing broader activity with skin and epithelial cells.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This study hypothesizes that postinflammatory hyperpigmentation in ashy dermatosis may result from basal cell apoptosis, as evidenced by consistent histologic findings across nine patients.

This study attempts to classify histomorphologic reactions to drugs to aid in diagnosing drug eruptions, which are common in hospitalized patients but lack specific diagnostic features.

This article reviews adverse skin reactions caused by chemotherapy and cytokine treatments, describing specific and nonspecific reactions, but reports no new clinical findings.

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

This report describes a case of sclero-atrophy localized to the frontal scalp following an injection of botulinum toxin type A, which has not been previously documented in the literature.

This study found that anti-TNF therapy-induced alopecia exhibits distinct clinical and histopathological features and can mimic psoriatic alopecia and alopecia areata, with some patients improving with topical treatment.

This case report describes a successful treatment of sarcoidal foreign body reactions caused by permanent makeup ink with local steroid injections, while also identifying the involvement of M2 macrophages in the reaction.

This figure in the publication investigates the relationship between expression levels and tumor burden but reports no specific findings or conclusions.

This study observed that multinucleate giant cells were present in 31% of biopsy specimens from patients with male pattern alopecia but not in other alopecia types, suggesting a potential histologic marker for androgenetic alopecia.

In this survey of dermatologists, pimozide was most commonly identified as the preferred first-line antipsychotic for treating delusions of parasitosis, followed by risperidone.

This case study suggests that overgrowth of microorganisms with hyperkeratosis may contribute to the induction of lichen planopilaris by disrupting the immune privilege of hair follicles.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

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 review highlights the increasing clinical applications of high-frequency ultrasonography in dermatology, particularly for assessing the depth of skin tumors and monitoring inflammatory skin diseases, but reports no new clinical results.

This study reports that adipose-derived stem cells can protect against radiation-induced dermatitis in rats by reducing apoptosis through lowering Cathepsin F expression, suggesting a potential new therapeutic approach.
