Neoplasia Flashcards
Presents with the classic triad of hematuria, palpable mass, and flank pain
RCC - hematuria is most common
Associated with paraneoplastic syndromes (ACTH, PTHrP, EPO, renin)
RCC
Most common renal malignancy
RCC
Gross exam reveals a yellow mass; microscopically, the most common variant reveals clear cytoplasm
RCC
Originates from the proximal tubule
RCC
Most common in men 50-70 years, increased incidence with smoking and obesity
RCC
Invades renal vein then IVC and spreads hematogenously to lung and bone, most commonly
RCC
Rarely may present with left-sided varicocele
RCC
RCC is associated with sporadic or inherited gene mutation on chromosome ____ of ______
3
VHL
Location of sporadic RCC . Major risk factor?
Upper pole of kidney
Smoking
Hereditary RCC are often bilateral and VHL is also associated with __________ in the cerebellum
Hemangioblastoma
Most common site of lymph node spread in RCC?
Retroperitoneal lymph nodes
Most common renal malignancy of early childhood (ages 2-4)
Wilms Tumor
Wilms Tumor Contains embryonic glomerular structures - main cell type is called a __________
Blastema (immature mesenchyme)
Associated with WT1 mutation, a tumor suppressor on chromosome 11
Wilms Tumor
WAGR syndrome - associated with WT1 loss
Wilms tumor
Aniridia (no iris)
Genital abnormalities
Mental and motor Retardation
Beckwith-Wiedemann syndrome - associated with WT1 loss
Wilms tumor
Neonatal hypoglycemia
Muscular hemihypertrophy
Organomegaly (including tongue)
Most common type of lower urinary tract cancer, usually arises in the bladder (can arise anywhere along the renal pelvis, ureter, bladder, urethra)
Urothelial (Transitional Cell) Carcinoma
Risk factors for urothelial carcinoma?
Cigarette smoke is major
Pee SAC
P - Phenacetin
S - Smoking
A - Aniline dyes (AZO)
C - Cyclophosphamide
Develops as a high-grade flat tumor and then invades, associated with p53 mutation
Flat pathway for urothelial carcinoma
Develops as a low grade tumor that progresses to a high-grade papillary tumor and then invades; not associated with early p53 mutations
Papillary pathway for urothelial carcinoma
Tumors are often multifocal and recur due to “field defect” phenomena
urothelial carcinoma
Malignant proliferation of squamous cells, usually involving the bladder
SCC
Painless hematuria (no casts) suggests…
bladder cancer
