This case study suggests that atrichia with papular lesions associated with common variable immunodeficiency may follow an autosomal-dominant inheritance pattern, differing from previous reports of autosomal recessive inheritance.

In this study, a novel E583V missense mutation in the hairless gene was identified in an Italian family with atrichia with papular lesions, reinforcing the significance of zinc-finger and LXXLL domains in this condition.

This case report describes the first known instance of a dilated pore of Winer, a type of follicular cyst, identified in a dog, specifically a 9-year-old neutered Goldendoodle, which was surgically excised after causing pain due to periodic ruptures.

This study describes the diverse histopathological patterns and clinical features observed in patients with folliculotropic mycosis fungoides, emphasizing the importance of accurate recognition to avoid diagnostic errors.

This case report documents a trichofolliculoma of the upper lip in a 70-year-old woman, highlighting its clinical presentation and successful surgical removal without recurrence.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

This study found that PDLLA filler treatment may help combat age-related hair thinning by reducing oxidative stress and enhancing hair follicle function in both cell and animal models.

This case report describes a 28-year-old man with widespread pigmented basal cell carcinomas and recurrent infections that were challenging to control, associated with nevus comedonicus and a rudimentary toe.

The baby’s hair loss was due to a rare genetic condition, not treatable by usual methods.

This case report documented a novel presentation of a canine viral plaque appearing as a solitary exophytic keratin-filled mass, highlighting the need to differentiate it from a hair follicle tumor.

This report describes cases of trichoblastoma and trichoepithelioma in mixed-breed dogs, highlighting their distinct microscopic characteristics without suggesting broader clinical implications.

The man's hair loss and skin papules were diagnosed as atrichia with papular lesions, not alopecia areata universalis.

This case report details an unusual instance of multiple eruptive milia in an otherwise healthy 3-month-old baby, characterized by widespread distribution and believed to be idiopathic due to the absence of associated genodermatoses.

This case report documents a rare presentation of congenital milia en plaque on the scalp of a five-year-old boy, with blaschkoid extension to the nuchal area, highlighting its uncommon location and onset.

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 study found that a skin lesion in a Samoyed dog did not match any single known follicular cyst or neoplasm type described in the literature.

This case report describes a 27-year-old woman who developed an epidermoid cyst in the left parotid gland following botulinum toxin injections, which was successfully treated with surgical removal.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

This case report describes an unusual occurrence of late-onset nevus comedonicus affecting both eyelids, with complications including bilateral ptosis and ectropion.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

In this case report, a 24-year-old male with a translucent nodule in the left nasolabial fold was diagnosed with a solitary fibrofolliculoma with cystic changes upon histopathology, emphasizing the rarity and potential for misdiagnosis of these benign cutaneous tumors.

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.

This case report describes a rare instance of nevus comedonicus with a multi-dermatomal unilateral pattern along the lines of Blaschko, treated unsuccessfully with topical tretinoin and oral retinoids.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.

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

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 case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.

This report diagnosed a 68-year-old man with comedonal folliculotropic mycosis fungoides based on clinical and histopathological findings, and found pegylated interferon alpha-2a with isotretinoin beneficial in reducing skin lesions.
