The above remarks on architectural and cytologic features, in aggregate, readily distinguish most cases of JGCT from AGCT.
One important tumor in the differential of the JGCT is the so-called large cell variant of small cell carcinoma of hypercalcemic type.
An occasional patient with a JGCT is pregnant, and pregnancy luteoma may rarely be in the differential because the latter may have follicle-like spaces (53) and the cells of that benign entity have abundant eosinophilic cytoplasm (Figure 12, F).
In conclusion, we experienced a rare case with atypical JGCT of malignant potential.
The histopathological examination established the diagnosis of JGCT.
The preoperative diagnosis of a JGCT is difficult, and it is usually initially diagnosed as a teratoma.

Roughly half of JGCT present in the first few days of life, and over 90% are diagnosed by six months of age.
Initial imaging of JGCT is usually accomplished by ultrasound, which shows a predominantly cystic mass or partly cystic lesion with prominent solid components.
Historically most cases of testicular JGCT have been treated with unilateral orchiectomy; however, testis-sparing enucleation has been performed with increasing frequency.
The pathology report confirmed the diagnosis of JGCT of the testis.
JGCT of the testis is a rare, benign, subset of sex cord-stromal tumours which also include Leydig cell, Sertoli cell and undifferentiated cell tumours.[sup.6] In the ovary, the adult form is much more common than the juvenile form; in the testis, the juvenile form is more common than the adult one.[sup.7] The JGCT of the testis has a tendency to occur in very young patients, mostly in the first 6 months of life.[sup.7] Ninety percent are found in infants of less than a year old.[sup.1]
