This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

SACUMAN, a rare condition causing hair loss without clear signs, is often misdiagnosed and needs scalp biopsies for accurate detection.

This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

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

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

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

This study reported that genetic changes in trichilemmal carcinoma resemble those in other skin cancers, with TP53 mutations associated with aggressive clinical outcomes.

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 study found that trichilemmal carcinoma shares genetic changes with other skin cancers, suggesting a similar pathogenesis, particularly in those with aggressive clinical courses linked to TP53 mutations.

This study reported genetic mutations in trichilemmal carcinoma similar to those found in other skin cancers, including TP53 mutations associated with aggressive disease.

This article reviews the characteristics and diagnostic criteria of tricholemmoma and tricholemmal carcinoma, detailing their clinical presentations and associations but reports no new clinical findings.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This case report highlighted the rarity and diagnostic challenges of a giant solitary trichoepithelioma occurring on the neck, noting that while typically benign, these tumors can rarely transform malignantly into basal cell carcinoma.

This case report identifies a potential new syndrome characterized by trichoepitheliomas and alopecia, which may be associated with myasthenia gravis.

This case report details a rare instance of malignant proliferating trichilemmal tumour in a 60-year-old male, emphasizing the significance of histochemical and immunohistochemical markers for accurate diagnosis and differentiation from squamous cell carcinoma.

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 an adolescent female with a linear array of trichoepitheliomas on her left neck, highlighting the clinical presentation of this benign tumor.

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.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

This case report describes a 26-year-old male patient with trichofolliculoma, highlighting dermoscopic features that aid its diagnosis and distinct characteristics from other similar lesions.

This report describes a rare case of multiple trichofolliculomas on the face, which clinically resembled multiple trichoepitheliomas.

The authors report a rare case of trichilemmal carcinoma in the thigh of a 71-year-old, emphasizing the importance of complete surgical excision to prevent recurrence and support patient prognosis.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

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 study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

Autoimmune conditions can be linked to trichoepitheliomas, with treatment focusing on cosmetic concerns.

This case report details the immunohistochemical study of cytokeratins in a trichofolliculoma, providing insights but no new clinical findings.
