What is a tunica albuginea cyst?

What is a tunica albuginea cyst?

The tunica albuginea is a dense fibrous sheath that surrounds, covers and protects the delicate contents of each testicle. The tunica albuginea is surrounded by a second layer, the tunica vaginalis. Tunica cysts, which are benign cystic masses, may arise from either tunic.

How common are tunica cysts?

Cysts of the tunica albuginea have been considered rare and only 28 cases have been reported in the urological literature (Frater, 1929; Arcadi, 1952; Mancilla-Jimenez and Matsuda, 1975; Turner et al., 1977; Mennemeyer and Mason, 1979; Sethney and Albers, 1980; Takihara et al., 1982; Valvo et al., 1983; Warner et al..

What does tunica albuginea form in the testis?

The tunica albuginea also extends into the testis, creating partitions between seminiferous tubules where sperm is produced. It has a bluish-white appearance and covers most of the inner layer of the tunica, the tunica vasculosa. Overlying this structure is the outer layer of the tunica, the tunica vaginalis.

What is the function of the tunica albuginea?

The tunica albuginea (TA) envelops the penile erectile bodies and is composed of organized fibrillar collagen interlaced with elastin fibers, which allow tunica expansion. It protects erectile tissue, promotes penile rigidity and length, and participates in the veno-occlusive mechanism.

What is the function of tunica albuginea?

The tunica albuginea is directly involved in maintaining an erection; that is due to Buck’s fascia constricting the erection veins of the penis, preventing blood from leaving and thus sustaining the erect state.

Can a cyst of the tunica albuginea be repaired?

A benign cyst of the tunica albuginea of the testicle, as demonstrated in the present case, does not require surgery. Cysts of the tunica albuginea are uncommon.

What kind of sheath is the tunica albuginea?

Are there cysts in the tunica vaginalis?

The tunica albuginea is surrounded by a second layer, the tunica vaginalis. Tunica cysts, which are benign cystic masses, may arise from either tunic. What is a tunica cyst?

How old do you have to be to have a tunica cyst?

In most cases, they are not symptomatic and are discovered incidentally by the patient, who is typically around 40 years of age. How are tunica cysts diagnosed?

Where does the cyst in the tunica albuginea come from?

Tunica albuginea cysts, regardless of size, are usually palpable. Tunica albuginea cysts arise from tunica albuginea (TA). The TA, a fibrous layer below the tunica vaginalis, closely covers the testicle. The posterior surface of the TA extends into the interior of the testis, forming an incomplete septum known as the mediastinum testis. [ 2]

The tunica albuginea is a dense fibrous sheath that surrounds, covers and protects the delicate contents of each testicle. The tunica albuginea is surrounded by a second layer, the tunica vaginalis. Tunica cysts, which are benign cystic masses, may arise from either tunic.

What to look for in a tunica cyst?

On ultrasound, the tunica albuginea can be seen as a 2-layered echogenic (containing lots of echoes) structure surrounding the testicle and the cyst as a small, regular fluid-filled structure abutting the surface of the testicle. On occasion, a tunica cyst may calcify. Microscopically, they are seen to contain fluid and cellular debris.

Is the tunica albuginea avascular in the ovary?

Unlike the other stromal compartments within the ovary, the tunica albuginea and the outer cortex containing primordial follicles are avascular. The factors initiating the changes in the cortical stroma resulting in formation of the tunica albuginea are not known.
