Abstract:
Epithelioid sarcoma is an aggressive and rare malignancy first recognized by Enzinger in 1970. It is known most commonly to affect the distal upper extremities in young adults. The classical "distal" form has a male predominance and can also involve other less frequent sites including lower extremities, proximal upper extremities, and the trunk. The "proximal" variant of this tumor is deep seated, tends to occur in older patients and predominantly develops in the pelvis, perineum, and genital tract. In the orbit, only a single report of two cases, which had a typical histopathologic appearance, has been previously published. We present the third case of orbital primary epithelioid sarcoma.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
