Coarse eosinophilic granules (so-called 'Paneth-like') can be seen in all grades of #prostatecancer #gupath Unlike true Paneth cells [GI tract], these cells are neuroendocrine marker (+), do NOT contain lysozyme

▪️Pseudomelanosis duodeni ▪️Etiologic considerations: iron deposition (iron pill ingestion, superficial bleeding🩸), macrophage metabolism of meds, charcoal, other substances 💊Associated meds: hydralazine, furosemide, hydrochlorothiazide #GIpath
