Dear Duane,
You have done an excellant job describing the lesion. The testicle produces sperm that make their way into the epididymis that is attached and draped over the posterior (back) aspect of the testicle. A head, body, and tail of the epididymis is described.
When an abnormality is felt on testicular self-examination an examination by a physician is warranted. If the physical examination is inconclusive or further characterization of a lesion is needed than a transcrotal testicular ultrasound examination should be performed. Finally if a testicular tumor is suspected blood tests for tumor markers should be obtained. Often a cyst in the epidyidimis is described an requires no treatment at all.
This information is provided for general medical information purposes only. Please consult your physician for diagnostic and treatment options pertaining to your specific medical condition. More individualized care is available through our department at the Henry Ford Hospital and its suburban locations (I-800-653-6568).
Sincerely;
