Hairy cell leukemia involving blood/marrow. Patient presented with cytopenias. Marrow not terribly hypercellular, so very easy to overlook an infiltrate like this if the flow isn't positive. #hemepath #pathology

👩🏻⚕️Day 111: I’ll call this piece “the field of aspergillus” 👩🏻🎨 it’s kind of like a field of flowers 💐 but much less likely to smell nice and waaaaaay more likely to cause lung infections in immunocompromised patients. #pathart #pathology #microbiology

This angiomatoid (malignant) fibrous histiocytoma has a lymphoid cuff at low magnification and hemorrhagic cystic spaces. This example shows desmin expression. These pediatric tumors usually behave indolently with rare aggressive behavior. https://t.co/VWopNi6JvQ
