This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This clinical report describes a method for using tattoo marks to help align a facial prosthesis for a patient with skin flap reconstruction.

This case study describes a 12-year-old boy with an unruptured epidermal inclusion cyst on his cheek, highlighting the role of dermatoscopy in diagnosing and differentiating cyst types for treatment.

In this study, researchers describe a rare case of trichoepitheliomas in a 7-year-old boy, characterized by multiple skin lesions in a Blaschko-linear pattern, hypothesizing it as a type 1 segmental mosaicism without detected CYLD gene mutations.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study suggests that the "spade sign" is a highly specific histopathologic feature of acne keloidalis, although its absence does not rule out the condition.

This case report describes a 21-day-old infant with erythematous annular scaly plaques and pustules on the face and scalp, which did not improve with topical corticosteroid cream.

In this case report, a rare instance of pilomatrixoma was identified in the left hand of a 40-year-old patient, with successful surgical treatment and no recurrence observed after four years of follow-up.

This report presents the second known case of erythema nodosum without typical associated conditions, which could be linked to mycoplasma infection, although no testing was conducted to confirm this in the patient.

This case study describes an elderly woman with distinctive black hair patches and scalp pigmentation, but it does not provide a diagnosis or new findings.

This study explored the immune environment of the hair follicle's bulge region and suggested that its unique signaling may prevent melanoma formation by lacking necessary proinflammatory signals for full oncogenic transformation, indicating potential strategies for melanoma prevention by replicating this immune-privileged environment.

This case report describes a unique instance of congenital triangular alopecia affecting the chin in a 12-year-old boy, noting the condition is typically benign with limited treatment options being necessary.

In this study, the researchers analyzed skin samples from Dun Mongolian horses to uncover molecular pathways linked to the "Bider" marking, identifying differential gene expression and several pigment-related signaling pathways that may play key roles in its formation.

This letter to the editor discusses the natural course of epidermolysis bullosa simplex with mottled pigmentation in a Japanese family but does not present new clinical results.

In this study, three patients with alopecia areata exhibited spotty absence of the whiteness of their nail lunulae, potentially due to defects in the matrical epithelium.

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.

Onychomatricome is a benign nail tumor with specific dermoscopic features that help distinguish it from cancer.

This report reviews familial cases of aplasia cutis of the scalp, noting large irregular defects at the vertex or anterior along the sagittal suture in six families.

This case report describes a 10-day-old female with aplasia cutis congenita, presenting with two spontaneously healing ulcers on her buttock and no associated abnormalities.

In this study, researchers reported a 0.11% occurrence of congenital triangular alopecia, recommending surgical treatment for women but not for men due to later potential development of androgenic alopecia.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

This case report describes a 10-year-old boy with a localized patch of partial alopecia and comedonal lesions, diagnosed as an atypical nevus comedonicus, and treated with topical tretinoin.

This case report describes a rare instance of a giant and atypical proliferating pilomatrixoma on the eyelid, successfully treated with surgical excision, with no recurrence observed after one year, emphasizing the need to excise and histologically evaluate enlarging periocular masses to rule out malignancy.

This letter to the editor presents a case of non-Herlitz junctional epidermolysis bullosa associated with a COL17A1 mutation and reports no new clinical findings.

This study identified distinct dermoscopic patterns associated with different types of scalp tumors, highlighting variability in lesions related to patient age, gender, and tumor thickness.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

This study describes a case of epidermolysis bullosa simplex where maternal somatic and germline mosaicism was identified, highlighting the significance for genetic counseling in sporadic cases.
