case_images: Complete cystic removal with femoral artery preservation was successful with minimal leakage of cyst wall (Figure 3).
case_images: Cystic content showed the clear, yellow fluid.

case_images: Cystic content had shown the clear, yellow fluid (Figure 4).
case_images: (a, b) H&E staining showed that the cystic wall is lined by a single layer of flat lining cells.

case_images: Microscopic examination was demonstrated as Figure 5. The cell lining was histologically supposed to be derived from endothelium or mesothelium by routine H&E staining (Figures 5(a) and 5(b)).
case_images: The cystic lining cells showed immunoreactive with CD31.

case_images: Immunohistochemical studies revealed the cell lining of the cyst was positive for CD34, CD31 (Figure 6), and D2-40 (Figure 7) and negative for calretinin.
case_images: Immunohistochemical study revealed that the flattened cystic lining cells are positive for D2-40.
