Fibrous pseudotumor is the third most common paratesticular mass, after lipoma and adenomatoid tumor. It is not a true neoplasm but represents a benign reactive fibrous proliferation resulting from one or several paratesticular elements, more often from the tunica vaginalis (12, 14, 22, 23, 47, 48, 54, 55).
Based on the histopathology and the IHC reactions, the lesion appeared benign and was diagnosed as adenomatoid tumor with psammoma bodies.

Whether it was dentigerous cyst transforming to adenomatoid tumor or a cystic variant of adenomatoid odontogenic tumor in the present case could not be stated with exactitude as initially to preserve associated tooth only part of cystic lining was removed for histopathological evaluation.
The final diagnosis of adenomatoid tumor was made (Figure 3).
In the paraffin-embedded (permanent) sections of the mass, the slit-like spaces were thought to be the glandular parts of an adenomatoid tumor or vascular structures and they stained negative for calretinin and CK7 and positive for CD34.
