This review explores the trichoscopic features of dark scalp, particularly the brown honeycomb pigment network, and its variations in different types of alopecia, but it presents no new clinical findings.

This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

This study found that complete surgical resection and multidisciplinary management were crucial for treating proliferating trichilemmal tumors, though malignant cases showed recurrence and mortality risks.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

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

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

This study reports that a 190,000 molecular weight protein, identified as trichohyalin, may play a matrix role in the development of inner root sheaths in hair follicles.

This case study identified the condition as Monilethrix in a 17-year-old female, characterized by a beaded hair appearance and linked to a genetic cause.

This report describes a case of trichostasis spinulosa, a condition with pruritic, black papules on the face caused by keratotic plugs with embedded vellus hairs.

This review discusses trichoscopic features of hair disorders in individuals with dark skin phototypes and reports no new clinical results; the authors emphasize the need for more specific diagnostic criteria for these populations.

This study presents a microscopic analysis of the pruritic variant of trichostasis spinulosa in two patients and reviews existing literature, reporting no new clinical results.

This study observed that melanogenesis in human hair follicles is linked to anagen phases, with melanocyte activity and enzyme expression being region-specific to the nascent bulb.

This review highlights that trichofolliculomas can resemble certain skin cancers, emphasizing the importance of recognizing their clinical features to avoid unnecessary surgery; it reports no new clinical results.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This article presents a case of trichostasis spinulosa, a common but often unrecognized disorder, diagnosed through dermoscopic examination of black macules revealing bundled vellus hairs, with the patient declining treatment.

This study found that Trichoscope can effectively reveal clinical features of alopecia areata and androgenic alopecia, making it a useful tool for diagnosis and monitoring.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

This study observed that multiple familial trichoepitheliomas commonly presented with a cribriform histopathological tumor pattern, differentiating them from solitary trichoepitheliomas.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

In this study, authors reported that reflectance confocal microscopy may aid in diagnosing trichofolliculoma by identifying specific features correlated with histopathology that can be difficult to discern with other methods.

This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.

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 report describes a case study of a 23-year-old female exhibiting multiple trichodiscomas, a type of benign tumor of the hair follicular discs common in familial cases and potentially linked to Birt-Hogg-Dube syndrome, though genetic testing was not performed due to financial constraints.

This review discusses the development and advances in studying trichogenic dermal cells for hair follicle morphogenesis, summarizing methods, bioassays, and molecular markers, but reports no new research findings.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

In this case study, a 69-year-old male with a neck swelling was diagnosed with a trichilemmal cyst, highlighting the importance of complete surgical excision for lesions with proliferative or malignant potential.

This study found that specific histologic features in skin biopsies can help support a diagnosis of traumatic alopecia (trichotillomania), but not all markers are distinct to the condition.

A woman had 13 non-cancerous cysts on her scalp successfully removed in one surgery.
