Semi And Nonseminoma


Seminoma

On CT scans, seminomas are usually large and homogeneous, with soft tissue attenuation. Areas of low attenuation often are present secondary to necrosis and hemorrhage.

Nonseminomatous tumor

Nonseminomatous tumors include embryonal carcinoma, endodermal sinus tumor, choriocarcinoma, and mixed germ cell tumor. On CT scans, these lesions are often large and heterogeneous, with large (>50%) areas of low attenuation. They may contain areas of calcification.

Laboratory Test

Anti–acetylcholine receptor antibody The anti–acetylcholine receptor (AChR) antibody (Ab) test is reliable for diagnosing autoimmune myasthenia gravis (MG). It is highly specific (as high as 100%, according to Padua et al).  [ 4 ]  Results are positive in as many as 90% of patients who have generalized MG but in only 50-70% of those who have only ocular MG; thus false negatives are common in cases of purely ocular MG. False-positive anti-AChR Ab test results have been reported in cases of thymoma without MG and in patients with  Lambert-Eaton myasthenic syndrome , small cell lung cancer, or rheumatoid arthritis treated with penicillamine, as well as in 1-3% of the population older than 70 years. Tindall reported AChR Ab results and mean Ab titers in a group of patients with MG (see the Table below).  [ 25 ]  Table.
