This case study describes a 70-year-old woman with a congenital skin condition, nevus sebaceus, who underwent hair transplantation which maintained hair growth for about 40 years; however, secondary tumors developed over time, highlighting the persistence of tumorigenic potential within nevus sebaceus.

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.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

This case series observed that solitary fibrofolliculoma is a rare lesion that can affect the eyelids, requiring histological examination for accurate diagnosis due to its nonspecific clinical appearance.

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 case report details a rare instance of eruptive vellus hair cysts in a 12-year-old male, highlighting its atypical morphology and axillary distribution, which has not been previously documented.

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 case report describes a rare instance of a giant and atypical proliferating pilomatrixoma on the eyelid, successfully treated with surgical excision, with no recurrence observed after one year, emphasizing the need to excise and histologically evaluate enlarging periocular masses to rule out malignancy.

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

Onychomatricome is a benign nail tumor with specific dermoscopic features that help distinguish it from cancer.

This case report adds to the understanding of neurofibromatosis type 1 by documenting an Egyptian child with the condition alongside multiple unusual congenital anomalies, highlighting the importance of considering NF1 when these features are present.

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

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study identified molecular differences between dysplastic nevi and common melanocytic nevi, including altered keratinocyte differentiation, increased hair follicle-related molecule expression, and distinct immune microenvironment characteristics in dysplastic nevi.

In this study, researchers describe a rare case of trichoepitheliomas in a 7-year-old boy, characterized by multiple skin lesions in a Blaschko-linear pattern, hypothesizing it as a type 1 segmental mosaicism without detected CYLD gene mutations.

A case study reported a 15-year-old boy with a diagnosis of giant folliculosebaceous cystic hamartoma on his right buttock, characterized by malformed hair follicles and sclerotized collagen.

Dermoscopy helped correctly diagnose a skin condition that was previously misidentified as a different hair loss disease.

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 review reports two new cases of porokeratotic eccrine and hair follicle nevus and analyzes all known cases in the Spanish and English literature, suggesting a link to a GJB2 gene mutation.

In this case study, a 34-year-old woman with a rare presentation of pilomatrixoma involving alopecia and skin hypopigmentation showed no improvement in these symptoms despite a 3-month trial of topical steroid treatment, highlighting a potential association between pilomatrixoma and microinflammation.
