The tunica vaginalis is the serous covering of the testis. It is a pouch of serous membrane, derived from the processus vaginalis of the peritoneum, which in the fetus preceded the descent of the testis from the abdomen into the scrotum.^{[citation needed]}

After its descent, that portion of the pouch which extends from the abdominal inguinal ring to near the upper part of the gland becomes obliterated; the lower portion remains as a shut sac, which invests the surface of the testis, and is reflected on to the internal surface of the scrotum; hence it may be described as consisting of a visceral and a parietal lamina.^{[citation needed]}

Visceral lamina

The visceral lamina (lamina visceralis) covers the greater part of the testis and epididymis, connecting the latter to the testis by means of a distinct fold. From the posterior border of the gland it is reflected on to the internal surface of the scrotum.^{[citation needed]}

Parietal lamina

The parietal lamina (lamina parietalis) is far more extensive than the visceral, extending upward for some distance in front and on the medial side of the cord, and reaching below the testis. The inner surface of the tunica vaginalis is smooth, and covered by a layer of simple cuboidal mesothelial cells. The interval between the visceral and parietal laminæ constitutes the cavity of the tunica vaginalis.^{[citation needed]}

Malignant mesothelioma of tunica vaginalis testis is a rare aggressive neoplasm with ∼200 cases reported so far. A correct preoperative diagnosis of this rare tumor is difficult. Fine-needle aspiration cytology (FNAC) is a rapid and inexpensive diagnostic tool that may prove helpful in such cases.
