Adverse Occurrence type:
Renal angiomyolipoma is typically a benign tumor and incidental finding estimated to occur with a frequency between 0.02-0.2%. Frequency is higher in conditions of tuberous sclerosis or lymphangioleiomyomatosis (https://www.kidney-international.org/article/S0085-2538(15)50139-7/fulltext). The Council of Europe does not discuss this lesion. It may rarely coexist with other renal cell neoplasms.
Time to detection:
3 months; found during biopsy to assess rejection
Alerting signals, symptoms, evidence of occurrence:
Rejection- no symptoms referable to angiomyolipoma
Demonstration of imputability or root cause:
Biopsy diagnosis of allograft kidney; tuberous sclerosis and angiomyolipoma also found at donor autopsy.

Expert comments for publication:
Allograft nephrectomy was performed at nine months (documented in followup letter to the editor listed above) due to rejection. No apparent symptoms related to angiomyolipoma, although the original author raised the possibility of the tumor facilitating rejection. We consider this unlikely.
