This study describes a case of generalized trichorrhexis nodosa and finds that defects in alpha-keratin chain formation and low cystine levels in hair may contribute to the condition.

This study examined patients with trichostasis spinulosa and identified distinct differences in the distribution and microscopic appearances of lesions compared to keratosis pilaris and eruptive vellus hair cysts.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

This article discusses a historical case of a rare skin disorder involving alopecia and follicular plugs reported in 1907; it presents no new findings.

This study found that the formation of the fibre cuticle surface in Merino sheep is similar to the epidermal stratum corneum process and not from a modified plasma membrane as previously thought.

This case report describes a 45-year-old woman with a trichoadenoma of the eyelid, emphasizing the importance of histopathological examination for accurately diagnosing excised eyelid lesions.

This case report describes a trichofolliculoma with perineural invasion, highlighting a rare and clinically significant finding in a typically benign hair follicle tumor.

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 case report describes a trichoblastoma in a 58-year-old man's leg, which was successfully excised without recurrence observed after 9 months.

This study demonstrates that the trichohyalin gene is located at chromosomal region 1q21, where several other genes related to epidermal differentiation also map.

In this case report, researchers observed multiple trichofolliculomas in family members, noting this as a rare manifestation of typically singular hair follicle hamartomas.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

This case report describes a 59-year-old woman with a rare trichoepithelioma on her eyelid, emphasizing the importance for optometrists to differentiate it from basal cell carcinoma.

This article presents a clinicopathologic challenge involving early leonine facies with alopecia in a young man and reports no new clinical results.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

This study found that trichoblastic fibroma and basal cell carcinoma cannot be differentiated by cytokeratin expression patterns, while trichoepithelioma lacks CK7 expression, distinguishing it from the other two neoplasms.

This case report details atrichia with papular lesions in a 4-year-old girl, highlighting specific histological findings on her scalp and other affected areas.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

This case report describes a patient with lichen nitidus whose lesions improved following treatment with oral astemizole and topical steroids, although spontaneous resolution remains a possibility.

This article discusses monilethrix, a rare human hair dysplasia caused by mutations in hair keratins, but reports no new clinical findings.

This case report describes a 65-year-old man's trichofolliculoma, a hair follicle-origin tumor, which appeared as a persistent cheek pore extrusion and was removed at the patient's request.

This study purified trichohyalin protein from pig tongue epithelium, characterizing its unique properties and structure, which may facilitate future functional research.

This study found that the keratin expression in basal cell carcinoma resembles that of the pilosebaceous apparatus, with uniform presence of certain keratins in all cases.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study demonstrated that keratin is widely present in various epithelial cells, providing structural strength and potential insights into the origin of cell lines.
