Axial T1W A., axial STIR B., sagittal T2W C., and axial contrast enhanced T1W D. images. A lesion located at the vulva with irregular contours and spicular extension to the adjacent subcutaneous fat tissue (arrows). Lipomatous area at the centre of lesion (curved arrows A. and C.). Multiple foci with variable signal characteristics and fibrotic changes around the lesion. Marked contrast-material enhancement of the lesion after intravenous administration of the contrast media (arrow, D.).

T2W and STIR sequences it was hyper intense and after the administration of contrast-material it was enhanced heterogeneously (Figure 1).
Photomicrographs of the patient. Honeycomb pattern interdigitates with lobules of subcutaneous fat (H and E, x100) A. Uniform population of slender fibroblasts arranged in storiform pattern (H and E, x200) B. Diffuse cytoplasmic CD34 (C; H and E, x100) and vimentin (D; H and E, x200) positivity C., D.

Histologic examination revealed a tumour specimen in a storiform and honeycomb pattern which was stained positive for CD 34 and vimentin indicating DFSP (Figure 2).
Coronal STIR A., axial T1W B., and axial contrast enhanced T1W C. MR images obtained 2 years after the surgery: postoperative changes in the operation area (arrows), no sign detected related to the recurrence.
