This case report details a rare instance of a giant cellular blue nevus on the scalp, highlighting its potential to damage underlying bone and hair follicles, alongside a separate alopecia areata lesion successfully treated with topical corticosteroid.

This case report describes the unexpected hair repigmentation surrounding a scalp tumor in a 74-year-old man, suggesting a potential link between the carcinoma and changes in hair pigmentation.

This case report describes a 43-year-old man who developed lupus miliaris disseminatus faciei after discontinuation of cyclosporine A post-stem cell transplantation, successfully treated with oral isotretinoin and topical tacrolimus.

In this case study, a 7-year-old boy with kerion celsi experienced persistent inflammation even after microbiological clearance; dermoscopic-guided removal of hair and keratin debris improved his condition, suggesting a novel inflammatory mechanism involving granulomatous response to keratinous debris in tinea capitis.

The researchers investigated a Maine Coon cat with suspected classical Ehlers-Danlos Syndrome and discovered a heterozygous deletion in the COL5A1 gene, underscoring the value of whole-genome sequencing for precise veterinary diagnostics.

This article describes a case of pruritic folliculitis of pregnancy, a rare, benign skin condition that occurs in the later stages of pregnancy and resolves after delivery without affecting maternal or fetal health.

This study concluded that ablative fractional lasers may induce hair regrowth in mice by activating the Wnt/β-catenin pathway.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

This case report discusses a rare instance of pseudolymphomatous folliculitis in a 19-year-old man, highlighting the challenge in diagnosing PLF due to its low clinical suspicion index and variable initial clinical diagnoses.

The man's hair loss and skin papules were diagnosed as atrichia with papular lesions, not alopecia areata universalis.

This case report describes two patients with a likely new type of pachyonychia, characterized by nail thickening and severe generalized hypotrichosis, possibly linked to a mutation in a hard keratin.

This study found that the polyurethane-cellulose acetate scaffold containing plasma rich in growth factors enhanced gene expression linked to wound healing compared to controls.

This study found that a polyurethane-cellulose acetate scaffold with plasma rich in growth factors may enhance gene expression related to wound healing in an experimental setting.

This article reviews the characteristics and inheritance patterns of keratosis follicularis spinulosa decalvans, but it does not present new clinical findings, noting the disease's complex and poorly understood pathogenesis.

PLLA injections can cause hair loss and skin issues.

A case study reported a 15-year-old boy with a diagnosis of giant folliculosebaceous cystic hamartoma on his right buttock, characterized by malformed hair follicles and sclerotized collagen.

In this study, a unique form of chronic superficial pyoderma gangrenosum with verrucous and ulcerative lesions was reported to heal without systemic corticosteroids in most patients.

This case report describes a family with autosomal dominant transmission of keratosis follicularis spinulosa decalvans, with observed treatment refractoriness in multiple topical and systemic therapies.

In this study, symmetrical acrokeratoderma was observed to frequently occur alongside ichthyosis vulgaris, with no specific therapy available for the condition.

This case report describes a rare instance of a Chinese Crested dog with leukocyte chimerism, normal female external genitalia, and hormonally active Sertoli cell tumors, demonstrating surgery as a curative treatment option.

This study found that PEGylated LUT-Aspasomes significantly improved neuroprotective effects in stressed rats, enhancing spatial memory, reducing depressive-like behavior, and preserving hippocampal architecture better than free luteolin. Additionally, it increased brain delivery and stability, suggesting potential for treating stress-related neurobehavioral disorders.

Granuloma faciale can occur on the scalp, especially in people with advanced hair loss, and may improve with treatment.

This article presents a rare case of cicatricial alopecia in a 59-year-old woman after using the epidermal growth factor receptor inhibitor gefitinib.

This study describes two new types of dermal keratinous cysts of the eyelids, derived from the pilosebaceous apparatus, each presenting distinct management challenges.

This case report describes the characteristic clinicopathological features of trichodysplasia spinulosa in two boys with acute lymphocytic leukemia, highlighting its resolution as immune function normalizes.

In this study, the combination of keratin-gelatin from poultry feathers promoted early acceptance and viability of full-thickness skin mesh grafts in experimental dogs compared to other treatments.

This study found that melatonin significantly improved metabolic and reproductive parameters in PCOS-induced rats, with effects similar to metformin.
