A 47-year-old man visited our hospital suffering from intensive pain of the swelling mass in his left inguinal region. He had never recognized the left testis in his scrotum, and felt the left inguinal mass growing slowly since a year ago. Computed tomography and Doppler uitrasonography revealed a mass approximately 5 cm in diameter separating from intestines in the abdominal cavity and not supplied sufficient blood flow. We suspected that the mass was a testicular cancer in cryptorchidism with testicular torsion and performed orchiectomy. At the time of the operation, the mass and the spermatic cord were twisted and prolapsed out of the aponeurosis of external abdominal oblique muscle. Histopathologically, malignant degeneration was demonstrated in the undescended testis, and the cell type was seminoma. We definitely diagnosed the mass as torsion of a testicular cancer in cryptorchidism prolapsing out of the inguinal canal.

D011391	Prolapse	The protrusion of an organ or part of an organ into a natural or artificial orifice.	Prolapses
D003456	Cryptorchidism	A developmental defect in which a TESTIS or both TESTES failed to descend from high in the ABDOMEN to the bottom of the SCROTUM. Testicular descent is essential to normal SPERMATOGENESIS which requires temperature lower than the BODY TEMPERATURE. Cryptorchidism can be subclassified by the location of the maldescended testis.

D013086	Spermatic Cord Torsion	The twisting of the SPERMATIC CORD due to an anatomical abnormality that left the TESTIS mobile and dangling in the SCROTUM. The initial effect of testicular torsion is obstruction of venous return. Depending on the duration and degree of cord rotation, testicular symptoms range from EDEMA to interrupted arterial flow and testicular pain. If blood flow to testis is absent for 4 to 6 h, SPERMATOGENESIS may be permanently lost.

D018239	Seminoma	A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. There are three variants: classical (typical), the most common type; anaplastic; and spermatocytic. The classical seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs. (Dorland, 27th ed)	Seminomas
