From: A rare case of multiple phosphaturic mesenchymal tumors along a tendon sheath inducing osteomalacia
Histopathological findings of the tumors. a Low power view of HE-stained sections of the mesenchymal tumors found in flexor halluces longus muscle tendon. b Higher magnification image for the above section that shows oval-shaped mesenchymal cells densely populated in fibrous background, osteoclast-like giant cells and histiocytes associated with haemorrhage and hemosiderin deposition. Mitotic activity and necrosis are absent. c Low power view of HE-stained sections of the tissue excised from distal phalanx. d Higher magnification image of the above tissue that shows hyaline cartilage and bone tissue
