Table 1.
The clinical data in 8 cases of benign orbital tumors with bone destructions in children.
Figure 1.
A–C: Patient with orbital eosinophilic granuloma (case4).
Figure 1A: Clinical appearance of fullness of the upper eyelid of the right eye. Figure 1B: Computed tomography (CT) shows erosion of an intraorbital soft tissue mass through anterior and posterior cortex of frontal bone, similar to malignant tumors. Figure 1C: The tumor tissues comprised pathologic Langerhans cells, eosinophils, scat-tered lymphocytes, plasma cells, and multinucleated giant cells (magnification ×400; hematoxylin-eosin stain).
Figure 2.
A–E: Patient with orbital leiomyoma(case7).
Figure 2A: Clinical appearance of a hard, un-movable, well-marginated mass measuring 15 mm×10 mm in the left temporal periorbital area. Figure 2B, C: Computed tomography (Axial, Figure 2B; Coronal, Figure 2C) revealed a 22 mm×13 mm well-defined soft tissue mass. There was marked destruction of the lateral orbital wall. Figure 2D: The histopathologic examination showed that the tumor composed of spindle-shaped, benign-appearing cells organized in fascicles or loosely arranged in a myxoid stroma (magnification ×200; hematoxylin-eosin stain). Figure 2E: In immunohistochemical staining, the specimen was positive for alpha-smooth muscle actin (magnification ×200).
Figure 3.
A–D: Patient with primary orbital intraosseous hemangioma complicated with hematoma (case8).
Figure 3A: Clinical appearance of lower eyelid mass with obvious upward displacement of the right eye. Figure 3B, C: Computed tomography scan (Axial, Figure 3B; Sagittal, Figure 3C) disclosed a smoothly outlined homogeneous soft tissue mass in the inferior-anterior part of the right orbit, with remarkable bone destruction of the lower orbital rim. Figure 3D: The histopathologic finding of primary orbital intraosseous hemangioma, consisting of the thin-walled blood vessels which are closely clustered and separated by normal bony tissue (magnification ×200; hematoxylin-eosin stain).
