This manuscript reports on the first case of perforating necrobiosis lipoidica in Colombia, marking the 19th documented case worldwide.

This study found that Naked trait mice exhibit a decrease in certain low-molecular-weight proteins in their hair, which contain high levels of glycine and tyrosine, compared to normal mice.

This study found that in poodles, perifollicular changes in the hair follicle glassy membrane are not always linked to calcium deposition.

This case report describes a 57-year-old Japanese male with a folliculosebaceous cystic hamartoma containing unusual hair shaft fragments, providing insight into its characteristic histological features.

This article reports that cocaine injections can lead to skin lesions containing talc crystals at the sites of injection.

This review discusses Chrousos syndrome, a rare condition caused by NR 3C1 gene mutations leading to glucocorticoid resistance, and reports no new clinical results; early identification and genetic testing are recommended for diagnosis.

This study examined two cases of bubble hair deformity using light and electron microscopy, suggesting that trauma to the hair shaft may contribute to this condition.

This case report describes an unusual nail tumor termed "onycholemmal horn" in a 77-year-old woman, highlighting its distinct histopathological features and the importance of excisional biopsy for accurate diagnosis.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This article reviews the role of LMNA gene mutations, particularly in Hutchinson–Gilford progeria syndrome, but does not report new experimental findings.

An elderly man with skin amyloidosis and abnormal blood proteins was monitored without finding widespread disease after 18 months.

This case study of a 50-year-old woman with myotonic dystrophy and multiple basal cell carcinomas suggests there could be a genetic predisposition for certain cutaneous tumors in such patients.

This study concluded that myositis in the reported case was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.

This study found that onychomatricoma can fully mimic the nail unit and differentiate toward the nail bed and isthmus, distinguishing it from other pilar tumors.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This case report describes a unique lesion in a 10-month-old girl, characterized by increased eccrine glands and hair follicles, leading to the proposed term "hybrid eccrine gland and hair follicle hamartoma".

This article describes a 10-month-old female with congenital smooth muscle hamartoma, highlighting the importance of differential diagnosis in congenital skin lesions due to potential malignancy risks.

This report describes a case of Rothmund-Thomson type congenital poikiloderma, noting minor skin changes, hair loss, and slightly elevated lysine and cystine in the urine.

This study confirms previous observations that benign lipogenic lesions may contain eccrine/apocrine glandular components, potentially due to adipocytic proliferation entrapping glandular structures.

In this study, researchers reported telocytes in the dermis of silky fowl embryos at different developmental stages, highlighting their immunophenotypes and interactions with other cells.

In this study, three cases of Cronkhite-Canada syndrome revealed small bowel mucosal lesions, but these findings did not correlate with clinical symptoms or steroid treatment outcomes.

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 article presents five family cases of monilethrix and reports that neither vitamins nor desquamative ointments are effective treatments, although symptoms may spontaneously regress over time.

This case report describes a 27-year-old female with systemic lupus erythematosus who presented with chilblain lupus erythematosus and melanonychia striata, emphasizing the rarity of such presentations in SLE patients.

This case report introduces 'onycholemmal carcinoma' as a designation for a slowly growing malignant tumor of the nail bed epithelium in a 69-year-old male, with no recurrence or metastasis observed over four years after treatment.

This study found that intracorneal vacuoles were common in various parakeratotic skin diseases in dogs, but large vacuoles were exclusively observed in congenital follicular parakeratosis.

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 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 reports a rare case of a 40-year-old woman with multiple calcified trichilemmal cysts, associated with alopecia universalis and suggesting a potential genetic link.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.
