Hepatic Perivascular Epithelioid Cell Tumor (PEComa): A Case Report.

Pathology and Laboratory Medicine, Saint Michael's Medical Center, Newark, USA.
Perivascular epithelioid cell tumors (PEComas) are a rare group of mesenchymal neoplasms composed of perivascular epithelioid cells. While commonly found in the kidney, uterus, and soft tissues, PEComas of the liver are exceedingly rare. We present a case of a PEComa incidentally discovered in a 73-year-old female patient undergoing evaluation for abdominal pain.

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms, commonly found in the uterus and retroperitoneum. Renal PEComas are exceedingly rare, often posing diagnostic challenges due to their resemblance to renal cell carcinoma (RCC) on imaging. We present the case of an 18-year-old male who presented with non-specific symptoms of fever, chills, and shivering.

BACKGROUND Perivascular epitheloid cell neoplasm (PEComa) is a rare mesenchymal tumor that is evaluated in the same tumor family as angiomyolipoma, sugar cell tumor of the lung, and lymphangioleiomyomatosis. Immunohistochemically, the disease can express melanocytic and myogenic markers, such as HMB45, HMSA1, MelanA/Mart1, and actin. The disease can be seen in almost every organ, especially the uterus and retroperitoneum.

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.

Article Synopsis
- Primary perivascular epithelioid cell tumors (PEComas) in the female reproductive tract are rare, with limited data on their risks and invasiveness, prompting a need for better understanding in diagnosis and treatment.
- A study conducted on eight patients with PEComa saw varied outcomes, with some undergoing successful surgeries while others showed new lesions or nodules post-treatment.
- Emphasizing complete lesion resection is crucial, as inadequate treatment raises recurrence and metastasis risks, highlighting the need for improved risk assessment strategies in managing PEComas.
