Benign Renal Angiomyolipoma With Inferior Vena Cava Thrombosis

Minimal fat renal angiomyolipoma with lymph node involvement: A case report and literature review

“…Previous studies have demonstrated that no local recurrence or distant metastasis were present after complete resection. 5,10 The true incidence of positive lymph nodes in patients with renal AML or minimal fat renal AML remains unknown, because regional lymph nodes dissection is rarely performed with this tumour type.…”

“…2 There is currently no clear evidence of involvement of regional limphatics in minimal fat renal AML, although recent studies suggested that AML might involve to peri-renal or renal sinus fat, regional lymphatics, 3,4 and other visceral organs, as well as inferior vena cava. [5][6][7] We review the available literature and report a case of invasive minimal fat renal AML involving regional lymph nodes. To the best of our knowledge, this is the first minimal fat renal AML with regional lymph nodes involvement reported in the literature.…”

Angiomyolipoma with caval extension and regional nodal involvement: Aggressive behaviour or just rare natural history? Case report and review of literature

“…7 In a few cases, AMLs have been found with perirenal tissue invasion, positive regional lymph nodes, IVC extension, and occasionally extending into the right atrium. 8,9 Classic AMLs are sporadic in 80% of cases, while the remaining 20% are associated with genetic syndromes, such as tuberous sclerosis complex, an autosomal dominant disease. In both cases, there is female and right kidney predominance.…”

The applicability of Ki-67 marker for renal epithelioid angiomyolipoma: experience of ten cases from a single center

“…Generally, classic renal angiomyolipoma follows a benign course in most cases yet may have alarming properties: nuclear pleomorphism and mitotic activity, extension into the vena cava (IVC), and spread to regional lymph nodes, without malignant progression [2,17]. Mittal et al reported a case of a benign renal AML with a tumor thrombus to the IVC, at 1 month after surgery, no thrombus within the IVC was detected with abdominal ultrasound and CT scan of the abdomen at 3 months post-operatively showed no evidence of recurrence [18]. However, patients who suffered from EAML would not be that fortunate.…”
