This case report highlights a rare instance of erosive pustular dermatosis of the scalp in a patient on afatinib, underlining the importance of early recognition and management of this adverse effect.

This report summarizes recent cases of the rare condition erythromelanosis follicularis faciei et colli to illustrate its varied clinical presentations.

This case report describes erosive pustular dermatosis of the scalp in a patient undergoing gefitinib treatment for lung cancer, and reviews literature on drug-induced cases of this rare condition.

This report from the UK reviews the literature on post-menopausal frontal fibrosing alopecia and highlights its under-recognition and distinctive characteristics compared to lichen planopilaris, but does not provide new results.

In this case report, a 65-year-old woman with non-small cell lung cancer experienced scarring alopecia with papulo-pustular lesions on the scalp due to gefitinib treatment, marking it as a rare instance of gefitinib-induced erosive pustular dermatosis of the scalp.

This study documented the onset of lichen planopilaris during treatment with etanercept.

This study found that estetrol (E4) significantly prolonged the anagen phase and increased hair matrix keratinocyte proliferation in cultured human hair follicles, suggesting its potential as a treatment for female pattern hair loss.

This study reported that EGFR inhibitor therapy in lung and head/neck cancer patients was associated with acneiform eruptions and severe skin dryness, which rarely necessitate discontinuation of treatment and can be managed symptomatically.

This study observed that trichoscopic changes associated with EGFRI treatment include pili torti and asymmetric hyperpigmented fusiform widening, along with dermoscopic skin manifestations such as scale and branching vessels.

In this study, finasteride was found to induce tissue-specific P-glycoprotein activity in the liver and kidney of rabbits after a 14-day treatment period.

This study identified 15 Iranian patients with PLEC variants linked to various plectinopathies and highlighted a novel association between a homozygous nonsense variant in PLEC and a rare combination of disorders including EB pruriginosa, muscular dystrophy, and congenital myasthenic syndrome.

This study found that platelet-rich fibrin provides more sustained therapeutic effects than platelet-rich plasma in inhibiting apoptosis and enhancing proliferation and migration of human endometrial stromal cells.

Nelfb is essential for dermal fat development and survival.

This study reported significant transcriptomic changes in keratinocyte and immune cell populations in a mouse model with EGFR-deficient epidermis, suggesting possible targets for mitigating adverse skin events in EGFR-targeted cancer therapy.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

Estetrol may help prevent hair loss and support hair growth in women.

This study found that the multifunctional FEA-PCEI dressing significantly accelerated wound healing, reduced scar formation, and promoted hair follicle neogenesis while providing antibacterial and anti-inflammatory benefits.

This study demonstrated that the Epidermal Biopotential Sensing System (EBSS) can measure digital biomarkers of pain in mice, suggesting potential applications in assessing pain and screening analgesics in populations with communication difficulties.

This study found that neutrophil-rich hair follicle inflammation caused by a monoclonal antibody targeting murine EGFR in mice involved TNFα and interleukin-1, suggesting these cytokines play a role in EGFR antibody-induced rashes in cancer patients.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This study observed that erosive pustular dermatosis of the scalp in elderly patients was effectively treated with high-potency topical steroids, with plasma and lymphocyte dermal infiltrates helping to confirm diagnosis.

This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.

This study found that prostaglandin receptors are widely expressed in hair follicles, suggesting a complex network of prostanoid pathways involved in hair growth control.

This case report describes a 49-year-old woman with metastatic adrenocortical carcinoma in the liver who experienced an abscopal effect after pulse electric field ablation, with PET/CT imaging showing complete resolution of three untreated lesions two months post-treatment.

This case report describes how discontinuing the EGFR inhibitor gefitinib led to rapid improvement of erosive scalp pustules in a woman with non-small-cell lung cancer, despite previous antibiotic and steroid treatment failures.

This study found that EGF receptors are aberrantly regulated and persist in cholesteatoma epithelium, suggesting a hyperproliferative character compared to normal human skin.
