Benign tumor in Kidney • Adenoma • Oncocytoma • Angiomyolipoma • Leiomyoma • Lipoma • Hemangioma • Juxtaglomerular tumor
Renal adenoma • most common benign tumor • asymptomatic & incidentally at autopsy • 7 - 22 % at autopsy
Renal oncocytoma • 3 - 5 % of renal tumor • M : F = 2 : 1 • Solitary & unilateral • tan & light brown • spoke - wheel appearance • Tx : radical nephrectomy
Angiomyolipoma (I)(Renal harmatoma) • 45 - 80 % in tuberous sclerosis (adenoma sebaceum, mental retardation, epilepsy) • bilateral & asymptomatic • 3 major histologic components mature fat cell smooth muscle blood vessel
Angiomyolipoma (II) • DIAGNOSIS US & CT로 진단 가능 US : very high intensity echo CT : -20~ -80 HU MRI : not considered
Angiomyolipoma (III) • Management : by Sx & size 1) < 4cm : yearly CT & MRI 2) > 4cm & aSx or mild Sx : semi-annually F/U 3) > 4cm & moderate or severe Sx : renal sparing or renal artery embolization
Other rare benign tumor • Leiomyoma • Hemangioma • Lipoma • Juxtaglomerular cell tumor
Adenocarcinoma of the kideny (RCC) • 3% of adult cancer • 85% of all primary malignant renal tumor • male : female = 2 : 1 • renal adenocarcinoma, hypernephroma, clear cell carcinoma, alveolar carcinoma
RCC • Etiology : unknown 1. cigarette smoking 2. analgesic abuse : phenacetin 3. occupation : shoe worker, leather tanner etc 4. coffee, diuretics, obesity, estrogen 5. familial form : autosomal dominant 6. ACDK : 4 - 9%
Pathology of the RCC • Proximal renal tubular epithelium • Gross : yellow to orange hemorrhage, necrosis, calcification • Micro. : clear cell granular cell sarcomatoid cell
Pathogenesis of the RCC • Vascular tumor that tend to direct invasion & extension • 1/3 metastatic disease at presentation • Lung, liver, bone, ipsilateral lymph node, adrenal gland, opposite kidney
Sx & Sign ( I )of the RCC • incidentally detected tumor : currently increasing • Internist’s tumor • Triad (10 -15%) : gross hematuria flank pain palpable mass
Sx & Sign(II)of the RCC • Sx secondary to metastatic disease : dyspnea, cough, bone pain • Paraneoplastic syndrome : 3 -10% erythrocytosis hypertension hypercalcemia non-metastatic hepatic dysfunction
Dx of the RCC ( I ) • Laboratory finding • anemia ( 30% ) • ESR increasing ( up to 75% ) • hematuria ( up to 60% ) • abnormal liver function test
Dx of the RCC ( II ) • X - ray findings IVP USG CT MRI Renal angiography Bone scan
DDx of the RCC • Renal abscess • Xanthogranulomatous PN • Angiomyolipoma • Renal pelvis tumor • Extra-renal mass
Tx of the RCC ( I ) • Localized disease ( stage I, II, IIIa ) • radical nephrectomy • regional lymphadenectomy • preoperative renal A. embolization
Tx of the RCC (II) • Disseminated disease • radical nephrectomy • RT • hormonal therapy • chemotherapy • B.R.M.
B.R.M.(Biologic Response Modifier) • Interferon-a • Tumor infiltrating lymphocyte(TIL) • Interleukin • Lymphocyte activating killer cell(LAK)
Follow - up of the RCC • regular interval (수술 후 첫 1년 3개월, 5년은 6개월 간격, 그 후 1년마다) • history, P/E • Chest X - ray • CBC, LFT • CT, Bone scan
Prognosis of the RCC • T1 : 88 - 100% 5YSR • T2 & T3a : 60% 5YSR • T3b : 15 - 20% 5YSR • T4 : 0 - 20% 5YSR
