Abstract
Angiomyolipoma (AML) is a benign tumor that mainly occurs in the kidneys.
Simultaneous involvement of the kidney and local regional lymph nodes is very
rare and might be misdiagnosed as a metastasizing malignant cancer. In the
present study, a 50-year-old woman was referred to our hospital after a routine
health screening ultrasound. Sporadic multiple renal AML with lymph node
involvement was suspected based on the clinical manifestations and radiologic
features. Partial nephrectomy was performed and a para-inferior vena cava lymph
node was removed. The pathologic results confirmed multiple AML with lymph node
invasion. We also reviewed the English-language literature regarding renal AML
with lymph node involvement. We found that middle-aged women were likely to
develop this disease and that loin pain was the main presenting feature. Most
patients had no history of tuberous sclerosis complex. Radical nephrectomy was
the predominant treatment. No local recurrence or distant metastasis occurred in
any patients after radical nephrectomy or partial nephrectomy. In conclusion,
renal AML with lymph node involvement is rare but can occur in both patients
with tuberous sclerosis complex and those with multiple sporadic AML. Partial
nephrectomy should be the first-line treatment, after which further treatment is
not necessary.
