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.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

This abstract discusses Alopecic and aseptic nodule of the scalp as a rare alopecia condition that may be underdiagnosed and reports doxycycline as a safe and effective treatment option.

This case report highlights the rare co-occurrence of Pili Annulati and Trichorrhexis Nodosa in a Syrian woman, underlining the need for further research into their relationship and treatment.

This study suggests that pseudopelade may be an autonomous disease based on its distinctive clinical and histopathological features not present in other scarring alopecias.

This study found that microencapsulated human hair dermal papilla cells successfully induced hair follicle regeneration on the dorsal skin of nude mice, unlike control groups with free cells or empty microcapsules.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

This case report describes successful hair regrowth after removing a nevus in a patient with perinevoid alopecia and concentric regrowth, which are rare patterns of alopecia areata.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This case report describes white piedra infection of the scalp hair with a synergistic bacterial infection in two US native sisters, highlighting its relevance in diagnosing scalp hair concretions despite its rarity in North America.

This study found evidence of Demodex mite involvement in the formation of horn cysts within eyelid papillomas, suggesting a role for the mite in tumor morphogenesis.

This article reviews the development of trichophytic closure techniques in hair restoration surgery aimed at reducing donor site scarring, but it does not report new clinical outcomes.

A rare skin growth was successfully removed without recurrence after one year.

This study reports a rare case of a 40-year-old woman with multiple calcified trichilemmal cysts, associated with alopecia universalis and suggesting a potential genetic link.

This case study describes a Doberman Pinscher with a unique alopecic variant of chronic cutaneous lupus erythematosus that progressed to systemic lupus erythematosus, highlighting a rare autoimmune alopecia form in dogs.

In this case series, cats infested with Lynxacarus radovskyi developed self-induced alopecia similar to flea allergic dermatitis, primarily affecting the perianal area.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This article reviews historical cases and descriptions of perifolliculitis capitis abscedens et suffodiens, highlighting its characteristics and treatment, but reports no new clinical findings.

This case report describes a 19-year-old woman with typical clinical and histopathological findings of trichofolliculoma, a rare hair follicle hamartoma usually located on the face or scalp.

This article reviews factors affecting follicular unit extraction, emphasizing the need to tailor procedures to individual patient characteristics, but reports no new experimental findings.

This case report documents a rare instance of a trichilemmal cyst occurring on the plantar surface of the foot, highlighting the necessity of histological examination for accurate diagnosis when clinical or radiological presentations are atypical.

This study found that the interdigital gland of Vembur sheep has larger secretory lobules in males than females, producing various compounds for chemical communication and foot protection.

This study found that canine hair follicle stem cells are located in the isthmus/bulge region of the hair follicle, surrounded by telocytes.

This study reported allergic dermatitis in Brazilian donkeys linked to Culicoides insect bites, characterized by severe itching and skin lesions. The potential treatment with copaiba oil and multivitamin emulsion was explored, revealing its promise for managing this condition.

In this histopathology study of nevus sebaceus, researchers observed distinct epidermal, sebaceous, follicular, and apocrine changes, including sebaceous hyperplasia and basaloid adnexal proliferation, which help differentiate it from similar conditions like basal cell carcinoma and trichoblastoma.

This study found that the development and differentiation of Merkel cells in C57BL mouse embryos' dorsolateral skin are linked to tylotrich follicle formation rather than to neural influences.

This case report describes a proliferating trichilemmal cyst that underwent malignant transformation, with specific keratins identified in the tumor but no epidermal keratin detected.
