Panel 1
From: Chest wall and intrathoracic desmoid tumors: surgical experience and review of the literature
Panel a and b: Conventional X ray and CT-scan showing complete compression of the right lung by the tumor-mass and consecutive dislocation of the mediastinum to the left. Panel c: Desmoid tumor of the right hemithorax (3580 g) is macroscopically composed of a well-defined capsule infiltrated by a collagen network with fibrotic sections. Panel d: Postoperative X ray: the right lung is compressed and poorly ventilated. Panel e and f: Histological characteristics; Elongated, slender, spindle-shaped tumor cells with small pale-staining nuclei and poorly defined boundaries are embedded in abundant collagen. Panel g: Low proliferation activity as evidenced by immunohistochemical detection of nuclear Ki-67 expression.
