In this case report, a 57-year-old man with chronic myelogenous leukemia developed a large, rapidly growing giant keratoacanthoma, highlighting the diagnostic challenges it poses compared to cutaneous squamous cell carcinoma, with surgical excision identified as the preferred treatment.

This study found that active telethermography could help identify cancerization fields in individuals with actinic keratosis by detecting hyperthermic halos around tumors, which showed significant changes after treatment with a photolyase device.

This abstract contains no research findings and pertains only to website navigation and policies.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

In this study, researchers observed that keratoacanthoma exhibits dynamic follicular differentiation throughout its stages, with changes in specific keratin expressions, and regressed lesions showing epidermal rather than follicular characteristics.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

Dermagraft and Dermalogen had a lot of granulation, while Alloderm, Integra, and ADM had good blood vessel growth for skin healing.

This case report describes a 7-year-old girl diagnosed with multiple eccrine pilar angiomatous nevi, a rare variant of eccrine angiomatous hamartomas, characterized by slow growth and generally benign behavior.

This study suggests that immunostaining for Keratin 15 may be a useful tool for differentiating between basal cell carcinoma and trichoepithelioma.

Two cases of a rare skin condition were successfully treated with laser therapy, offering a non-surgical treatment option.

This study suggests that cutaneous lymphadenoma is a distinct benign lymphoepithelial tumor characterized by androgen receptor expression, hair follicle stem cell markers, and common EGFR gene mutations.

This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.

This review compiles epidemiological data on actinic keratoses and suggests promoting strategies like early diagnosis and photoprotection to prevent progression to skin cancer, but it reports no new clinical findings.

This study suggests that using growth factors and ADSC-conditioned medium can enhance keratinocyte viability and migration in epidermal transplantation, potentially improving chronic wound healing rates with a patient-dependent effect.

Organ transplant recipients have a higher risk of skin cancer over time, atopic dermatitis skin shows unusual bacterial and fungal patterns, a new tool for measuring hidradenitis suppurativa severity was created, and gene expression changes in male baldness suggest new treatments.

This study proposes a two-step method that may enhance the generation of stem-like epidermal cells with superior proliferation and differentiation potential for skin regeneration.

This study found that increased ACE2 expression, prompted by mechanical stretch, promotes skin regeneration and reduces dermal thinning during tissue expansion by enhancing collagen synthesis, suggesting ACE2's potential to improve clinical outcomes in reconstructive surgery settings.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This study proposes a new treatment protocol combining autologous regenerative therapy with mesotherapy and photobiostimulation for androgenetic alopecia, leveraging adipose-derived stem cells to stimulate hair follicle regeneration.

This study demonstrated that the tracheal xenotransplant procedure is an effective technique for assessing the invasiveness of epidermal keratinocytes and studying factors affecting hair follicle formation.

In this laboratory study, researchers observed that mouse vascular endothelial cells exhibit dynamic changes after exposure to ionizing radiation, including a transient endothelial subpopulation that facilitates vascular-epidermal communication and skin repair, with shifting roles in angiogenesis and immune surveillance over time.

This study found that ingenol mebutate treatment led to gene expression changes in actinic keratoses, with complete lesion clearance in 40% of patients and identified genetic markers potentially predicting treatment response.

This study found that high skin expression of amphiregulin in acute graft-versus-host disease was associated with severe disease grade, poor overall survival, and increased non-relapse mortality.

In this case report, researchers identified Arthroderma vanbreuseghemii as the cause of a familial fungal infection, which was successfully treated with itraconazole and topical terbinafine cream.

This report explores the potential cellular origins of keratoacanthoma lesions on the oral mucosa, noting that it reports no new results.

This case report highlights an unusual trichoscopic appearance in alopecia areata due to dithranol staining, which may obscure typical patterns and reveal atypical vascular features in the interfollicular spaces.

This study concluded that a combination of three specific dermoscopy features provides the highest diagnostic value for distinguishing actinic keratosis from other facial lesions.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.
