Abstract
BACKGROUND

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm that predominantly affects the kidney and uterus. The occurrence of this tumor in the liver, particularly with simultaneous involvement of the liver and kidney, is exceedingly uncommon. Pathological diagnosis is the gold standard. PEComas usually show positive immunohistochemical staining for melanocytic (HMB-45, Melan-A) and myoid (SMA, muscle-specific actin) markers.

CASE SUMMARY

We presented a noteworthy case of malignant PEComa affecting both the liver and kidney in a 53-year-old man with tuberous sclerosis complex (TSC). FAT2 and TP73 mutations in the kidney were identified and positive expression of diagnostic markers including HMB-45, Melan A, and TFE3 were detected. In addition, we demonstrated that hepatic artery perfusion chemotherapy was ineffective for hepatic PEComa, while surgery remained the most effective approach. Everolimus showed an excellent efficacy in the postoperative treatment of the tumor.

CONCLUSION

Surgical treatment is preferred for malignant PEComa affecting liver and kidney, especially with TSC; everolimus is effective postoperatively.

Core Tip: Perivascular epithelioid cell tumor (PEComa) is rare. Herein, we present the case of a 53-year-old man with the concurrent presence of malignant PEComa in both the liver and kidney, accompanied by tuberous sclerosis complex. During treatment, the hepatic artery perfusion chemotherapy was ineffective for hepatic PEComa, while surgery remained the most effective approach. Everolimus showed an excellent efficacy during the postoperative treatment of the patient. This report provides valuable insights for the diagnosis and treatment of PEComa, paving the way for future clinical practice.
