For the pathology trainees- calretinin IHC is great for dxing Hirschsprung's dz. Pics from same case, the distal aganglionic segment is dead neg for calretinin. The proximal normal segment shows cal positivity in ganglion cells, and also in mucosal nerve twigs.#gipath #pathology

The first-ever vaccine for malignant brain tumors reported safe and effective in an early trial. It triggers the desired immune response against the tumor cells. https://t.co/7jR5Ph6m6f

Pathologists! Here’s a classic case of plasmablastic lymphoma presenting as colonic polyps. In addition to stains shown, HHV8 must be done to exclude HHV8+ DLBCL, particularly if patient is HIV+ or from endemic area (was negative in this case) #hemepath

[Judith Ferry @judith_ferry]

Pathologists! Here is a small mesenteric lymph node removed with a bowel DLBCL. Node has intact architecture but some germinal centers are monotonous & partly or mostly replaced by intensely BCL2+ cells. In situ follicular neoplasia! Clonally related to the DLBCL. #hemepath
