Primary nonkeratinizing squamous cell carcinoma of the scapular bone: A case report

Figure 1 Three-dimensional computed tomography reconstruction. A and B: Osteolytic destructive lesion in the right scapular bone.

Figure 2 Magnetic resonance imaging A (t2-tse) and B (pd-tse-fs) show an osteolytic destructive lesion in the right scapular bone, invading the surrounding muscles and soft tissues.

Figure 3 Histological findings. A: Histopathological examination of the biopsy specimen shows malignant tumor cells in the trabecular bone space but no typical keratin pearls (hematoxylin and eosin stain; original magnification, 100 ×); B-D: Immunohistochemical labeling reveals that the tumor cells are reactive to cytokeratin 5/6, p63, and p40 (original magnification, 40 ×).

Figure 4 Primary nonkeratinizing squamous cell carcinoma of the right scapular bone. A: Surgically resected specimen shows a dark red ovoid mass originating from the right scapula that appears creamy-white and soft on cross section; B: The right humeral head, right collarbone, and surrounding muscle were used to reconstruct the resulting defect.
