Abstract:
Orbital fibrous histiocytomas can be difficult to diagnose and manage. These tumors, especially those with intermediate histologic features, often recur. Historically, non-invasive tests to differentiate scars from recurrent disease have a high error rate. We present a case of recurrent orbital fibrous histiocytoma in which the diagnosis was established with poitron emission tomography (PET) scans. This technique may be helpful in difficult cases to differentiate scars from a recurrent mesenchymal tumor.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
