A primary solitary vascular tumor of calcaneum: case report and review of literature

Figures

• 

  Fig. 1. Lateral and axial x-rays of the calcaneum show a lytic lesion in the anterior calcaneum without periosteal reaction or peripheral sclerosis

• 

  Fig. 2. Sagittal T1W image, Sagittal T2W image and Coronal PD image of the right ankle show hypointense signal on T1WI and hyperintense signal on T2W/PD images with mild adjacent marrow edema on T2W images. No obvious soft tissue mass associated with lesion

• 

  Fig. 3. CT-guided core needle biopsy of the lesion

• 

  Fig. 4. Axial and coronal PET-CT image shows hypermetabolic mediastinal lymph nodes and the hypermetabolic calcaneal lesion

• 

  Fig. 5. Sagittal and coronal post biopsy CT image shows scattered osseous debris with post-biopsy cortical disruption/fracture

• 

  Fig. 6. Lateral x-ray shows excision of right calcaneal lesion with argon beam and filling of defect with cement/Steinman pins

• 

  Fig. 7. Axial PET-CT image of the ankle obtained a year after treatment on follow up scans shows no hypermetabolic lesion

(A): Distinctive malignant vascular neoplasm characterized by predominant cords and clusters of epithelioid tumor cells and foci of spindle tumor cells within a characteristic myxoid to hyaline matrix, at 20x. (B): Malignant epithelioid cells in a myxoid background, with intracytoplasmic vacuoles at high power 40x. Rectangle; Intracytoplasmic vacuoles with epithelioid tumor cell
