This case report highlights a 40-year-old Indian male diagnosed with follicular vitiligo, presenting as graying hair and depigmented patches, and emphasizes the importance of distinguishing this rare variant from similar conditions like alopecia areata due to its unique presentation.

This abstract contains no research findings; it describes website service information and options for accessing content from JAMA Dermatology.

This study hypothesizes that postinflammatory hyperpigmentation in ashy dermatosis may result from basal cell apoptosis, as evidenced by consistent histologic findings across nine patients.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This article discusses localized repigmentation of hair, suggesting it may be an indicator of underlying melanoma, and emphasizes the need for careful diagnostic evaluation.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

This review discusses the clinical manifestations and genetic basis of pigmentary mosaicism, highlighting its varied phenotypic expressions, but reports no new clinical results.

This article reports a rare combination of rapid-onset halo nevi, nonsegmental vitiligo, and premature scalp hair graying.

This abstract contains navigation and subscription information for JAMA Dermatology and reports no new clinical findings.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

Repigmentation in vitiligo may come from melanocyte stem cells in the skin.

This case study highlights that vitamin B12 deficiency can cause reversible hyperpigmentation, illustrated by a vegetarian female patient whose skin lesions improved after treatment.

This case report describes the histopathological features of nevus psiloliparus in an 11-year-old girl, noting "shadow" follicular units with loosely arranged collagen and reduced elastic fibers.

This review discusses various genetic and acquired conditions associated with poliosis circumscripta and reports no new clinical results.

This article reviews follicular melanogenesis, detailing how melanin synthesis and its regulation in hair follicles depend on a complex interplay of cellular and molecular mechanisms, but reports no new clinical findings.

The man has a disease causing skin patches, thickened nerves, and mild muscle weakness.

This report found follicular red dots in patients with scalp pigmentary disorders, suggesting they might be linked to the scalp's vascular structure and may have implications for conditions like discoid lupus erythematosus.

This case report highlights a rare instance of CD8-positive hypopigmented mycosis fungoides causing alopecia areata-like changes, emphasizing the necessity of scalp biopsy in such presentations.

This study observed that in pemphigus vulgaris patients, hair loss and alopecic patches may result from anti-desmoglein autoantibody-mediated acantholysis and inflammatory changes, leading to non-scarring alopecia with potential for regrowth after treatment.

This study found that increased PHGDH expression in mice led to earlier melanin and melanocyte presence in hair follicles but did not induce cancer.

This report describes a child with ulerythema ophryogenes marked by eyebrow hair absence and progressive skin atrophy, whose condition did not improve despite elevated vitamin A levels via injections.

This report discusses a case of an intradermal nevus in a 42-year-old woman and provides no clinical findings beyond a biopsy showing hyperkeratosis and cellular pigmentary changes.

This article provides an overview of lipedematous scalp, a rare condition characterized by a thickened scalp without hair loss, and emphasizes the need for further research due to limited case reports.

This case report describes persistent depigmented hair regrowth from an alopecia areata patch, challenging the previous assumption that such regrowth is only temporary.

This study developed a mouse model to mimic PHGDH gene copy number gain, finding that increased PHGDH expression leads to abnormal melanin production, which may offer insights into its role in melanoma.

This review discusses the potential relationship between lichen planus pigmentosus and frontal fibrosing alopecia, presenting a case study but reporting no new clinical findings.

This case report describes a 52-year-old woman with a rare combination of pemphigus vulgaris and pemphigus foliaceus on the scalp, initially misdiagnosed as psoriasis, who achieved clinical remission and hair regrowth with corticosteroid treatment.

This case report describes a rare instance of reversible melasma-like hyperpigmentation linked to vitamin B12 deficiency due to pernicious anemia, and explores possible mechanisms for this association.

This study observed that white hair follicles in vitiligo patients may repigment following epithelial grafting and phototherapy, suggesting potential cosmetic improvements in vitiligo treatment.
