A- aspirate clot (?)
B- biopsy (H&E)
C- touch imprint
D- bone marrow aspirate
E- unstained bone marrow aspirate
Is this a common pattern observed in treated Ewing sarcomas of the bone?
Viable tumor consisted exclusively of perivascular rosette-forming clusters!

Here's my first case of appendiceal goblet cell adenocarcinoma! Further sampling revealed cell clusters floating in extracellular mucin (high grade feature).

24 yo boy with testicular torsion. Within rete testis columnar cells with cribriform architecture and pseudoinvasive features are found. These findings are suggestive of adenenomatous hyperplasia of rete testis!

The bizarre cells are PAS positive (shown here) and negative to Grocott stain.
Final diagnosis: amebic liver abscess!

Resection of the IV hepatic segment: wall of an abscess cavity lined by necrotic-inflammatory tissue containing the same macrophage-like cells. Each element presents with one or multiple eosinophilic globules in the cytoplasm
CD20 staining reveals the presence of mature B cells infiltrating the bone marrow, forming an aggregate and perisinusal Indian files, typical of Marginal Zone Lymphoma (MZL).
