This paper reports a case of sebaceous carcinoma developing at the site of chronic candidiasis in a patient with keratitis–ichthyosis–deafness syndrome, without presenting new generalizable findings.

This case report documents a rare instance of a trichilemmal cyst occurring on the plantar surface of the foot, highlighting the necessity of histological examination for accurate diagnosis when clinical or radiological presentations are atypical.

This case report describes a flap advancement technique following skin expansion as a successful method to address primary essential cutis verticis gyrata, preserving hair growth and improving cosmetic outcomes.

This report presents a case of molluscum contagiosum virus infection within an epidermoid cyst in a 13-year-old on long-term steroid treatment, highlighting its rare occurrence and need for histological examination for accurate diagnosis.

This case report describes a 39-year-old female with cutis verticis gyrata and cicatricial alopecia, emphasizing the need for further understanding of the potential genetic associations and underlying mechanisms.

This study reports two new cases of Gomez-Lopez-Hernandez syndrome and suggests that trigeminal anesthesia and/or partial scalp alopecia may be key criteria for diagnosis.

This study observed that basal cell carcinoma on the scalp shares more similar characteristics with truncal lesions than facial lesions, despite the scalp's proximity to the face.

This review discusses facial gender confirmation surgery, particularly focusing on the upper third of the face, and reports no new clinical results; it emphasizes virtual surgical planning and postoperative care.

This case report describes a 5-day-old male infant with a constellation of symptoms, including leptomeningeal angiomatosis, hair follicle nevus, and congenital alopecia, potentially representing a novel neurocutaneous syndrome.

This article reviews the case of a 2-year-old boy with rhombencephalosynapsis and considers its potential links to Gomez–López-Hernández syndrome, suggesting further research into its genetic causes; no new clinical results are reported.

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.

In this study, researchers developed an enhanced rodent model of trigeminal neuralgia, demonstrating that structural and functional changes in the anterior cingulate cortex are linked to chronic pain and emotional disturbances, and chemogenetic inhibition of specific neurons could alleviate symptoms.

In this report, researchers described a potential new variant of mucinous nevus, characterized by dilation of hair follicle pores and fibromucinous stroma in both the papillary and perifollicular dermis.

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 article reviews the characteristics, common locations, and causes of epidermoid cysts, noting that surgical excision is the standard treatment, but it reports no new clinical findings.

In this case report, a 34-year-old with a slowly growing mass near the right parotid gland was diagnosed with pilomatrixoma, a rare benign hair follicle tumor, which was only confirmed pathologically after surgical excision.
