#MICROSCOPIC #Diagnosis → poor differentiated SCC (grade 3) #Features Distributed cells Nuclear atypia Nuclear pleomorphism NO KERATIN PEARLS NO SQUAMOUS NESTS

#MICROSCOPIC #Diagnosis → moderate differentiated SCC (grade 2) #The_black_arrows Keratin pearls #Features Nuclear atypia Nuclear pleomorphism Irregular nuclear membrane It has keratin pearls less than SCC grade 1

#MICROSCOPIC #Diagnosis → well differentiated squamous cell carcinoma (grade 1) #The_black_arrows Keratin pearls #The_blue_arrow Nest of squamous cells with eosinophilic cytoplasm #Most_commen_cause HPV

#MICROSCOPIC #Diagnosis 👉🏻 Wilms tumor ( Nephroblastoma ) #The_black_arrows Tubules #The_white_arrows Blastema #The_red_arrows Stroma

#MICROSCOPIC #Diagnosis 👉🏻 Wilms tumor ( Nephroblastoma ) #The_black_arrows Tubules #The_white_arrows Blastema #The_red_arrows Stroma #The_microscopic_features - Undifferentiated blastema ويلي تكون spindle shape and hypochromatic   - Tubules - Stroma

#GROSS #Diagnosis 👉🏻 Wilms tumor ( Nephroblastoma ) #The_black_arrows Tumor ✫ Gross description - Tan yellow , soft - lobulated

#MICROSCOPIC #Diagnosis 👉🏻 Chromophbe renal cell carcenoma #The_microscopic_features - cells polymorphisme  - hyperchrmatic nucleus - Cytoplasm clear (scantl

#MICROSCOPIC #Diagnosis 👉🏻 Papillary renal cell carcenoma #The_black_arrow Psammoma bodie وعشان تشبه glomerular قال عنها glomeruloid pattern

#MICROSCOPIC #Diagnosis 👉🏻 Papillary renal cell carcenoma #The_black_arrow Papillary بسبب القطع بين وكانها microcytic #The_blue_arrows Foamy macrophages

Papillary renal cell carcenoma

PAPILLARY RENAL CELL CARCINOMA ✫ Gross description - Well circumscribed with pseudo capsule - Tan yellow to red brown - hemorrhage - Necrosis - Aries from cells of renal tubules ✫Microscopic description - Small cuboidal cells arranged on single layer on papillary cores - Cells are small with uniform - Scant pale (not clear) cytoplasm - hyperchromatic nuclei without nucleoli - Papillary cores often contain foamy macrophages - May have psammoma bodie

#MICROSCOPIC #Diagnosis 👉🏻 Clear cell carcenoma #The_black_arrows Hemorrhage #The_blue_arrows Nest of tumor cells
