From: Postoperative recurrence of desmoid tumors: clinical and pathological perspectives
Histological features of desmoid tumors in the proximal part of the left thigh of a 29-year-old woman (arrows) (a–d). (a) Desmoid tumors invaded into the skeletal striated muscle aggressively. Degeneration of skeletal muscle cells could be seen (HE × 100). (b) Budding-like protrusion of the lesions invading into the muscles could be seen on the juncture of tumors and muscles (HE × 40). (c) Isolated small lesions in muscles were found away from the main part of the tumor (HE × 40). (d) Microscopically, desmoid tumors were poorly circumscribed on tumor-ligament boundary (HE × 40).
