In this study, researchers reported a rare case of nevus comedonicus with hair growth in a 26-year-old male, challenging prior reports that affected lesions typically lack the capability to develop terminal hair.

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

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

In this study, a curved nonrotary punch was found to achieve the lowest follicular unit transection rates of less than 5% compared to conventional rotary punches in hair transplantation for patients with tightly curled Afro-textured hair.

Tufted folliculitis is common in patients with folliculitis decalvans.

In this study of folliculitis decalvans, researchers found that compound follicular structures in scalp biopsies are primarily composed of terminal anagen follicles, surrounded by fibrosis and inflammatory cell infiltrate, which could enhance understanding of this condition.

This case study reports on a rare occurrence of trichoadenoma in the vulva of a 25-year-old female, describing typical histological features of the tumor.

The authors present a case of punctate follicular porokeratosis, suggesting it as a distinct clinical entity distinguished by keratotic lesions originating specifically from hair follicles.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

This study reported that a new extraction technique using cautery and forceps is a simple, effective treatment and diagnostic procedure for eruptive vellus hair cysts, with no recurrence after 4 months.

This study proposes that seasonal alopecia and reproductive changes in six female fossas at the San Diego Zoo may be linked to hormonal changes associated with reproductive activity.

This study reported that 39.7% of Amargosa voles had mite-associated lesions, which may severely impact their health and fitness.

This study found that a curcumin-labeled particle-associated antiseptic penetrated deeper into hair follicles in porcine skin than particles without antiseptic.

In this case report, a benign trichoadenoma was identified in a 42-year-old man as a skin-colored nodule on the cheek, with histopathology confirming the diagnosis and differentiating it from similar conditions like pilomatricoma and sebaceous cyst.

This report describes a rare case of recurrent hair growth in the floor of the mouth, suggesting heterotopia as the possible cause in an adult male.

This case report describes an 89-year-old woman with a recurrent benign proliferating trichilemmal tumor on her back, highlighting its misdiagnosis as a sebaceous cyst and successful excision with free margins.

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.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

This study documents dominant transmission and complete penetrance of uncombable hair syndrome in a family, despite the father lacking visible abnormalities.

This report discusses two cases of porokeratotic eccrine ostial and dermal duct nevus and porokeratotic eccrine and hair follicle nevus, suggesting they may represent a single clinical entity, but reports no therapeutic outcomes.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

This study suggests that pili annulati is likely more common than traditionally thought, highlighting the importance of recognizing its characteristic clinical and trichoscopic features for accurate diagnosis.

This study found that micro-CT imaging can effectively identify vascular structures in rat models of congenital hypospadias, providing anatomical insights for selecting preputial vessel flaps in surgical procedures.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This case report documents the first known instance of an ectopic sebaceous gland and duct within a hair follicle in a 21-year-old male with persistent acneiform eruption.

The study demonstrated that bulge stem cells from rat vibrissa follicles respond to adult dermal papilla signals, inducing hair bulb formation and regenerating hair structures in vivo.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.
