An ultrastructural study of intramuscular melanocytes in PET/Wmr mice

open access: yes, 1978
An examination of the lateral head of the gastrocnemius of the PET/Wn!.r mouse was made with an electron microscope. Cells of the perimysium and endomysium were described and the relationship of these cells to muscle cells was characterized.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

open access: yesClinical Genetics, EarlyView.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

Cortical‐Hypothalamic Assembloids Uncover the Cortical Regulation of Hypothalamic Responses to Fatty Acid

open access: yesCell Proliferation, EarlyView.
By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.

Novel Histopathologic Features of Diffuse Blue‐Gray Hyperpigmentation Associated With Kratom Use: A Case Report and Literature Review

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Drug‐induced hyperpigmentation accounts for 10%–20% of acquired pigmentary disorders and can be misdiagnosed for other causes such as melasma, post inflammatory changes, or heavy metal deposition. Kratom (Mitragyna speciosa), a Southeast Asian plant with an opioid‐like profile, has been increasingly used in the United States for ...

Dermatologic Toxicities Associated With Novel Pan‐RAS/RAF Inhibitors

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Background The mitogen‐activated protein kinase (MAPK) pathway plays a key role in cell‐cycle regulation and tumor progression in cancer. Dermatologic toxicities (DTs) to newer pan‐RAS (RMC‐6236) and pan‐RAF (LXH254/naporafenib) inhibitors are emerging.

Diagnostic Utility of PRAME Immunohistochemistry for Distinguishing Acral Melanoma From Acral Melanocytic Nevi

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Introduction Preferentially expressed antigen in melanoma (PRAME) immunohistochemistry helps distinguish non‐acral melanocytic lesions, but few studies have addressed its value in acral lesions. We aimed to identify an optimal PRAME cut‐off score to differentiate acral melanoma (AM) from acral melanocytic nevi (AMN).
