Renal Adenoma

Adenoma of Kidney


  • The findings are presented along with a review of the literature. There were 4 males and 1 female ranging in age from forty-two to sixty-three years. Each presented with a mass on excretory urography, and 1 contained calcification.[ncbi.nlm.nih.gov]
  • Several of these markers might be present in each single case. The interpretation is that their ultrastructural characteristics do not indicate an origin from a special segment of the nephron.[ncbi.nlm.nih.gov]
  • Previously reported infants with malignant and benign solid tumors causing humoral hypercalcemia have presented with large abdominal masses.[ncbi.nlm.nih.gov]
  • Abstract Autopsy findings of a 34-year-old Japanese male with stomach cancer in a renal allograft are presented.[ncbi.nlm.nih.gov]
  • In this issue of the Journal, Mazal et al. 1 present compelling evidence that these unusual adenomas originate from . . . Julie R. Ingelfinger, M.D.[nejm.org]
Clubbed Finger
  • On admission, clubbed fingers richitic rosaries and a palpable node in the neck were the major physical findings. Laboratory examinations revealed hypercalcemia had elevated levels of plasma parathyroid hormone (PTH) in a c-terminal assay.[ncbi.nlm.nih.gov]
Abdominal Mass
  • Previously reported infants with malignant and benign solid tumors causing humoral hypercalcemia have presented with large abdominal masses.[ncbi.nlm.nih.gov]
  • Classic symptoms - combination of flank pain, hematuria and a palpable abdominal mass occur in less than 10%. In about 30% of patients, there are unusual abnormalities seen that may be due to presence of renal cell carcinoma.[clevelandurology.net]
  • See separate articles Abdominal Masses, Loin Pain and Haematuria which discuss the various causes. Investigations Urinalysis, cytology, culture and sensitivity should be performed to exclude urinary tract infection.[patient.info]
  • , based on criteria for papillary renal cell carcinoma Note : small tumors of clear cells are considered to be small renal cell carcinomas, clear cell type and with malignant potential Microscopic (histologic) images Case of the Week #43 AFIP images Xanthoma[pathologyoutlines.com]
  • This study identifies two distinct groups of adenomas according to size, histological type and extent of sclerosis, and suggests that small adenomas of the mixed tubulopapillary type and with basophilic cells have little or no malignant potential.[ncbi.nlm.nih.gov]
  • Using 5 cases as examples, a suggested approach is outlined.[ncbi.nlm.nih.gov]
  • Renal adenomas had predominant histochemical features of the distal tubulus, suggesting differentiation to a distal tubulus-like histology.[ncbi.nlm.nih.gov]
  • However, as demonstrated by this case and others, metastasis can occur, therefore, it is suggested that the term renal adenoma no longer be used.[ncbi.nlm.nih.gov]
  • AVS is a technically challenging test, but lateralization suggests ipsilateral adenoma. F.[clinicaladvisor.com]


Multiple Renal Cysts
  • Bilateral multiple renal cysts in a 46-year-old man were pointed out incidentally by ultrasonography. Some of the left renal lesions were considered to be RCC, and left radical nephrectomy was performed accordingly.[ncbi.nlm.nih.gov]


  • The treatment of the renal adenoma is based on the imaging of the tumor. But this method of ascertaining the nature and size of the adenoma is inadequate. In this case, more sophisticated technology is applied for the treatment of the disease.[healthdrip.com]
  • One should use the criteria of size, gross characteristics, a frozen section biopsy, and the status of the other kidney to decide between tumor excision, nephrectomy, and no further treatment.[ncbi.nlm.nih.gov]
  • Noninvasive treatment approaches are usually preferred because the risks for the patient are much lower.[wisegeek.com]
  • Previously, it was thought that small (less than 3cm) solid tumours of the kidney were benign because they rarely metastasized; their histological similarity to renal cell carcinoma now results in similar treatment to their malignant relation i.e. surgical[gpnotebook.co.uk]


  • Prognosis Metastases have occurred with very small papillary primaries, but the prognosis is generally excellent. References 1 Renshaw, A. A. (2002). "Subclassification of renal cell neoplasms: an update for the practising pathologist."[e-immunohistochemistry.info]
  • Such tumors involve special aspects of both diagnosis and therapy and also have a distinctive prognosis.[books.google.de]
  • Prognosis is excellent with surgical Therapy. Postoperatively patients need to be monitored with serial imaging and biochemical tests [ 1 ].[hoajonline.com]
  • Prognosis [ 1 ] Kidney cancer survival is improving and has increased in the last 40 years in the UK. 50% of people diagnosed with kidney cancer in England and Wales survive for ten years or more (2010-11). 56% of people diagnosed with kidney cancer in[patient.info]

  • Epidemiology These are very common incidental findings. They are found more commonly in kidneys containing renal cell carcinoma or oncocytoma, particularly the hereditary form of papillary renal cell carcinoma.[e-immunohistochemistry.info]
  • Definition / general Low grade (usually) neoplasm also known as renal cortical adenoma Epidemiology Commonly found at autopsy: 10% at age 21 - 40 years, 40% at age 70 - 90 Increasing numbers during life are being detected with more widespread whole body[pathologyoutlines.com]

  • No other predisposing factors have been defined, and prevention is not possible. What are the symptoms? Most patients with an adrenal adenoma will have no symptoms caused by the adenoma.[netdoctor.co.uk]
  • The combined use of two drugs that are prescribed for other conditions, eflonithine and sulindac, may prevent the development of adenomas or the recurrence of colon cancer.[encyclopedia.com]
