Abstract:
Conjunctival dermoid cysts are a rare subtype of dermoid cyst usually presenting in adulthood. The authors report a case of a recurrent conjunctival dermoid cyst with reactive lymphoid hyperplasia that was immunohistochemically demonstrated to be polyclonal. Follicular centers that were present within the cyst wall were negative for Bcl-2 and positive for the immunohistochemical markers CD20, Bcl-6, CD10, and Ki67, which helped to differentiate the lesion from a follicular lymphoma. The lesion did not recur after 14 months of follow-up.

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...
