Telomerase reverse transcriptase immunohistochemical expression is sensitive but not specific for TERT gene amplification in acral melanoma
CONCLUSIONS: The clinical utility of TERT IHC to predict TGA status in AMs appears to be limited given its low specificity and positive predictive value.PMID:37400233 | DOI:10.1111/cup.14494

GRM1 gene fusions as an alternative molecular driver in blue nevi and related melanomas
Mod Pathol. 2023 Jun 28:100264. doi: 10.1016/j.modpat.2023.100264. Online ahead of print.ABSTRACTActivating mutations in GNAQ, GNA11, CYSLTR2, and PLCB4 genes are regarded as the main oncogenic drivers of blue nevi (BN) and blue malignant melanocytic tumors. Here we report four cases of blue melanocytic neoplasms devoid of these mutations but harboring GRM1 gene fusions. In this short series, there was no gender predominance (sex ratio = 1). The mean age at diagnosis was 40 years (range: 12-72). Tumors were located on the face (n=2), forearm (n=1) and dorsum of the foot (n=1). Clinically, a plaque-like pre-existing blue ne...

Uric acid is a major chemical constituent for the whitish coloration in the medaka leucophores
Pigment Cell Melanoma Res. 2023 May 30. doi: 10.1111/pcmr.13102. Online ahead of print.ABSTRACTIn whitish parts of teleost skin, the coloration is attributed to a light scattering phenomenon within light-reflecting chromatophores, namely leucophores and iridophores, which contain high refractive index materials in their cytoplasmic organelles, leucosomes and light-reflecting platelets, respectively. Previous chemical examinations revealed that guanine is a major constituent of the materials in the platelets of the iridophores, while, in leucophores, the detailed chemical nature of the materials contained in the leucosomes ...
