A woman's hair loss was correctly diagnosed as Lichen planopilaris after initial misdiagnosis, highlighting the usefulness of trichoscopy in diagnosing hair disorders.

The study found that Temporal Triangular Alopecia often starts in early childhood, mainly affects the left side of the scalp, and has no effective treatment except surgery.

The study found that Temporal Triangular Alopecia often starts in early childhood, while Folliculitis Decalvans is characterized by tufted hairs and redness around hair follicles.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

This study in a Lithuanian veterinary clinic observed diverse histomorphological skin changes in alopecic dogs caused by various rare diseases, including hyperkeratinization and pigmentation disorders.

Up to 10% of hair loss patients might have early signs of a condition called Lichen Planopilaris.

This study found that an acne complex animal model using rabbits showed more pronounced clinical symptoms and measured changes compared to the traditional Kligman model.

This study found that topical and intralesional corticosteroids are effective in treating the primary symptoms of lichen planopilaris and promoting hair regrowth in the active perimeter of alopecic patches.

Keratosis Pilaris Atrophicans causes skin scarring and might be treated with a new synthetic retinoid.

Folliculitis decalvans mainly affects middle-aged African American men and is treated with antibiotics.

This study found that both CO2 laser combined with topical methotrexate and calcipotriol plus betamethasone treatments improved nail psoriasis similarly, but some symptoms showed no improvement.

This case report describes an 18-year-old male with IFAP syndrome, confirmed by total hair loss, severe photophobia, and characteristic skin changes, marking a rare presentation of the condition.

This study demonstrates that overexpression of K16 in transgenic mice disrupts normal keratinization, leading to hyperkeratosis, acanthosis, and alterations in the skin's epithelial cells.

This article discusses the multifactorial nature of acne, including its association with follicular hyperkeratosis, sebaceous lipids, Propionibacterium acnes, and perifollicular inflammation, but reports no new clinical findings.

This study reports the first keratin gene mutation affecting the tail domain, leading to a unique cytoskeletal abnormality and severe epidermal hyperkeratosis, highlighting the tail domain's critical role in keratin organization.

In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.

This study reported that tail tip lesions in dairy cows include granulation tissue, purulent-necrotizing inflammation, and hyperkeratosis, potentially caused by ischemia.

This study focused on equine sarcoid, the most common tumor in horses, and described its types, clinical signs, and histopathological characteristics such as hyperkeratosis and changes in the hair follicle and dermis.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

This report discusses a case of an intradermal nevus in a 42-year-old woman and provides no clinical findings beyond a biopsy showing hyperkeratosis and cellular pigmentary changes.

In this study, researchers examined the skin of Baikal seals, identifying two main skin pathologies potentially linked to global warming and an unknown viral pathogen, suggesting immune inflammatory processes associated with environmental changes may be affecting these seals.

This study investigated the skin of 12 Baikal seals and identified two main skin pathologies potentially linked to global warming and changes in Lake Baikal's ice regime, including koilocytosis and inflammation associated with a possible viral pathogen.

This case report documents a 3-year-old guinea pig with hormonally active ovarian cysts, cystic endometrial hyperplasia, and bacterial endometritis associated with a uterine foreign body.

This study reports the first documented case of a cat with non-thymoma-associated exfoliative dermatitis showing both clinical and histological resolution after treatment with ciclosporin A, suggesting it may be an effective therapy for this immune-mediated condition.

This chapter discusses the roles of vitamin C in brain function and its potential impact on behavior during periods of deficiency, reporting no new experimental findings.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.

This study found that TRPV3 ion channels on human epidermal keratinocytes suppress cell proliferation, induce cell death, and trigger a proinflammatory response, suggesting a role in cutaneous inflammatory processes.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This case report details a 21-year-old woman with dermatopathia pigmentosa reticularis, presenting with generalized reticulate hyperpigmentation, diffuse noncicatricial alopecia, onychodystrophy, palmoplantar keratoderma, and poorly developed dermatoglyphics.
