case_images: PET-CT, showing a soft tissue mass approximately 5.5x5.7x9.0 cm in the vulva, vagina, and cervix, with irregular shape, unclear border, and with a maximum standardized uptake value (SUV[max]) of 2.4.. Notes: (A) Atrial volume, (B) coronal volume, and (C) sagittal volume.. Abbreviation: PET-CT, positron emission tomography-computed tomography.

case_images: Fluorodeoxyglucose positron emission tomography scan was performed and found a soft tissue mass lesion of 5.5x5.7x9.0 cm across the vulva, vagina, and cervix with an irregular shape, ill-defined boundary, and with a maximum standardized uptake value (SUV[max]) of 2.4 (Figure 1).
case_images: H&E stain of the biopsy sample.. Notes: There were medium-sized to large cells with finely dispersed chromatin, prominent nucleoli, and abundant eosinophilic cytoplasm (x400).. Abbreviation: H&E, hematoxylin and eosin.

case_images: Ki67 was expressed in 70% of the tumor cells (Figures 2 and 3).
case_images: Immunohistochemical stain of the biopsy sample.. Notes: The tumor cells were positive for myeloperoxidase (MPO), CD34, CD68, and negative for CD3, CD20. Ki67 evaluation was of 70% of the tumor cells (x200).
