This case report describes a 59-year-old woman with cicatricial alopecia and multiple skin lesions, including nodules and plaques, with biopsy results showing a lymphocytic infiltrate and collagen replacement.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

The authors concluded that milia, steatocystoma multiplex, and eruptive vellus hair cysts may be subtypes of multiple pilosebaceous cysts with overlapping histologic features.

This study reports on a patient whose symptoms, including trichoepitheliomas and clinical alopecia, may suggest a new syndrome possibly linked to myasthenia gravis.

This study found evidence that polythelia pilosa, previously excluded from classification, should be reintroduced as it marks true aberrant mammary structures in men and hirsute women.

This study describes five patients with porokeratotic adnexal ostial nevus, a rare skin disorder, highlighting its clinical features and proposing a new encompassing term for related conditions.

This exchange discusses interpretations of syphilitic chancres, noting disagreement over whether multiple lesions are atypical given historical references that describe primary chancres as often being single.

This case report describes alopecia universalis-like hair loss occurring in two patients with cutaneous T cell lymphoma, providing clinical, dermoscopic, and pathologic features to help differentiate it from alopecia areata universalis.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

This case report describes an atypical presentation of eruptive vellus hair cysts on the elbows, where standard diagnostic techniques were unreliable due to the loss of cystic structural integrity.

In this study, researchers examined the skin of Baikal seals, identifying two main skin pathologies potentially linked to global warming and an unknown viral pathogen, suggesting immune inflammatory processes associated with environmental changes may be affecting these seals.

This study reported no Cx30 expression in normal interfollicular human epidermis and minimal expression in some skin structures, with faint detection in porokeratosis of Mibelli patient skin.

More research is needed to understand and treat cicatricial alopecias.

This study describes a newly identified mite species, Demodex zalophi, found on captive sea lions and highlights its unique traits, including being the first of its kind described in marine mammals.

This study describes three additional cases of encephalocraniocutaneous lipomatosis, emphasizing the importance of examining patients with ocular and ipsilateral skin lesions for this rare neurocutaneous disorder.

This study investigated the interdigital glands in sheep, highlighting their apocrine sweat glands' ultrastructural characteristics and positive lectin reaction, but reported no new clinical results.

This study observed that cutaneous lymphocytosis in cats is a slowly progressive and relatively benign disease, but predicting individual clinical outcomes from skin lesions was not possible.

In this study, veterinary examinations of 150 domestic canines and felines revealed that M. canis was the predominant dermatophyte, affecting 9 cats and 9 dogs, with dogs showing more severe lesions and higher neutrophil counts in the cytological analysis.

This study seeks to clarify the terminology and classification of keratoacanthoma and similar squamous cell carcinoma lesions with central keratin-filled craters to aid in accurate differential diagnosis.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

This study observed distinct differences in hair characteristics between individuals with cardio-facio-cutaneous syndrome and Costello syndrome, highlighting the role of the RAS pathway in these RASopathies and aiding clinical diagnosis.

This report describes two cases of aplasia cutis congenita with hair collar signs and hemangioma, which may suggest neural tube defects, although imaging showed no bone or neural tissue abnormalities.

This case report describes instances of lipedematous scalp and lipedematous alopecia in white adults, indicating these rare conditions may be more widespread and frequent in this population than previously thought.

This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

This case study documented a black male newborn developing large bullae that healed with hypopigmentation, suspecting proteolytic enzymes in keratinocytes caused the collagenolysis responsible for the condition.

This study reports that hyperaesthetic leucotrichia primarily affects Arabian and American paint horses, occurring mainly in summer, with histological differences from erythema multiforme despite some shared features.

This study demonstrated that hiPSC-derived hair-bearing skin organoids lacked sufficient type VII collagen at the epidermal-dermal junction, indicating a need for further maturation to model certain forms of epidermolysis bullosa effectively.

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 study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.
