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

Journal 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 ...

BRAF V600E and Pten deletion in mice produces a histiocytic disorder with features of Langerhans cell histiocytosis.

PLoS ONE, 2019
Langerhans cell histiocytosis (LCH) is characterized by the accumulation of Langerin (CD207)-expressing histiocytes. Mutational activation of mitogen-activated protein kinase pathway genes, in particular BRAF, drives most cases. To test whether activated

Enhanced Melan‐A Red Chromogen Labeling in Melanoma Compared to Nevus Cells: A Diagnostic Aid in Dual Multiplex Immunohistochemistry With Ki67

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Distinguishing melanoma cells from nevus cells remains a diagnostic challenge, particularly in cases where melanoma exhibits nevoid morphology or nevus cells display atypical or epithelioid features. Accurate identification is essential for proper measurement of Breslow depth in melanomas arising in association with nevi and for ...
