More on pheochromocytomas (https://t.co/g4quwLrUs6):
These tumors classically have characteristic "zellballen" architecture featuring well-defined nests of tumor cells surrounded by delicate fibrovascular stroma. The cytology is highly variable, but cells may be large with abundant granular basophilic cytoplasm.

➡️Granulomatous response to extravasated spermatozoa (intensely basophilic aggregates), which can be engulfed by macrophages
(spermiophages)
➡️Occurs in up to 42% of patients after vasectomy (as seen in this patient)
➡️Chronic inflammation and fibrosis can produce a mass-like lesion that clinically mimics a neoplasm

while the actual pattern of CIS isn't really prognostic, it is important to help remember the spectrum of morphologies!

*Ravi once swapped schoolbooks for hard labour.
Encouraged by the local CRY learning centre, Ravi rediscovered learning through games, stories, and support. His confidence grew.
“I want to inspire others in my village to leave work behind and go back to school,” says Ravi.
In well-differentiated Pancreatic Neuroendocrine Tumor (PanNET), the neoplastic cells can occasionally have voluminous cytoplasm (but still maintain their plasmacytoid appearance). (FNA)
