ST mass, inguinal. KRT+/loss of INI. Nice example of proximal-type

A great opportunity!

The diagnosis for this well-demarcated, recurrent subcutaneous mass with unusual clear cell features and chondroid differentiation remained a mystery until #molpath correlation: Ossifying fibromyxoid tumor Unusual patterns described in this #BSTPath #dermpath collaboration

Spitz nevi with 11p gains are histologically distinctive, typically intradermal with pronounced desmoplastic stroma, an infiltrative growth pattern, and pleomorphic nuclei. Activating HRAS mutations with secondary 11p gain likely drive their unique appearance. #dermpath

A deep dive into SFT epigenetics reveals site-specific DNA methylation patterns, highlighting possible markers for distinguishing primary vs. metastatic tumors. Read more: sciencedirect.com/science/articl… #BSTpath #sarcoma

One of my favorite 40x fields I've ever seen! Beautiful ladybird cells (neoplastic cells with a cytoplasmic rim of hemosiderin) in a tenosyonvial giant cell tumor. #BSTpath

We’ve long known that epithelioid #sarcoma can be divided into proximal and classic subtypes, which have distinct clinical and morphologic features. Now, a new study by Sigalotti et al. gives us molecular insight behind these subtypes. Fascinating work! sciencedirect.com/science/articl…

Malignant melanotic nerve sheath tumor (MMNST): heavily pigmented, pleomorphic, SOX10/Melan-A positive (shown), often paraspinal in younger patients. Key to distinguish from melanoma—MMNST frequently has PRKAR1A inactivation. #BSTpath #Dermpath

Optical Genome Mapping (OGM) ie "Next Generation Karyotype" Exciting new molecular technology - very useful in #BSTPath No sequencing (an enzymatic step only) and provides unparalleled genomic resolution for structural variants including fusions/translocation, deletions,

Dartmouth Health Patholology is growing and seeking academic pathologists to join our team. Top priorities: GYN, Breast, GU, Cyto, & GI subspecialty training. Salaries and facility resources are highly desirable. Northern New England is a lifestyle hidden gem. DM for add'l info.

Is CD1a (MTB1) the best stain for leishmaniasis (after H&E)? Giemsa was negative in this case. #dermpath

An interesting paper describing an intermediate class of melanocytic neoplasms driven by MAP2K1 mutations. thelancet.com/journals/ebiom…

Dartmouth Pathology Team Lunch during #USCAP25 #USCAP #DHPathRes

If you couldn’t attend Dr. Kerr’s Darcy A. Kerr lecture on fibro-osseous lesions of the craniofacial skeleton, check it out later with the on-demand option on the #USCAP25 website. Highly recommended! Dartmouth Health Pathology Residency

My colleagues! Sign up! 👇 Jeremiah Karrs, DO Dartmouth Health Pathology Residency
