Abstract
Perivascular epithelioid cell tumour (PEComa) is an extremely rare neoplasm with
distinctive morphology and specific expression of immunohistochemical markers.
The lesion is typically diagnosed in middle-aged women, with few reports of
paediatric cases, and there is no standardized treatment for the tumour type.
Here, the case of a 17-year-old female, who presented with painless
haematochezia for 2 days and was diagnosed with gastrointestinal PEComa of the
sigmoid colon with regional lymph node metastasis after serial examination, is
presented. She was treated by surgical resection of the tumour and cytotoxic
chemotherapy comprising 900 mg/m2 gemcitabine and 100
mg/m2 docetaxel every 3 weeks for six cycles. Haematochezia did
not recur, and complete response was achieved, with progression-free survival at
the 24-month follow-up examination. Surgical resection with adjuvant
conventional cytotoxic chemotherapy may be considered as an option for treating
gastrointestinal PEComa.
