1
Q

What is epididymitis and what is a test that can be done to see if it is this disease?

A

Q

What is the treatment for epididymitis?

A

For patients younger than 35 (GC/Chlamydia): Ceftriaxone IM then doxycyline for 10 days. For patients older than 35 or history of anal intercourse (Enterobacteriaceae), fluoroquinolone for 10-14 days.

Q

What test can we do to differentiate b/w Testicular torsion vs epididymitis?

A

Elevation of the testes on someone suffering from testicular torsion will not relieve the pain slightly as it does in epididymitis.

Q

Why does Seminoma have a good prognosis?

A

It is radiosensitive and has a late metastasis (when found, they have most likely not metastasized).

Q

What do we see in histology of Seminoma?

A

Large cells and lobules w/ watery cytoplasm, giving it a “fried egg” appearance. This “fried-egg” appearance is also used in koilocytes in HPV and oligodendrogliomas.
