Tunical fibromas are benign, painless tumors that arise most frequently from the tunica vaginalis, but they can arise from the tunica albuginea
, the spermatic cord, or even the testicular parenchyma in rare cases.
21) Although they can show minimal infiltration into the adjacent testicle and abut the tunica albuginea
, invasion into the tunica has not been described.
In one large series, involvement of the epididymis and spermatic cord was seen in 60% and 39% of cases, respectively, whereas involvement of the tunica albuginea
is very rare.
However, unnecessary orchiectomy can be avoided because splenic tissue can be dissected away from the tunica albuginea
This occurs as the venules beneath the rigid tunica albuginea
are compressed, resulting in near-total occlusion of venous outflow (Fig.
Peyronie's disease is a focal inflammatory reaction accompanied by progressive fibrosis and formation of plaques within the tunica albuginea
They frequently involve the tunica vaginalis, with rarer cases arising from the tunica albuginea
, epididymis and spermatic cord.

10,12,28) Important margins to be examined in partial penectomy specimens include (1) proximal urethra and surrounding periurethral cylinder consisting of epithelium, lamina propria, corpus spongiosum, and penile fascia; (2) proximal shaft with corresponding corpora cavernosa separated and surrounded by the tunica albuginea
and Buck fascia; and (3) skin of shaft with underlying corporal dartos (28) (Figure 1).
The tunica albuginea
forms a dense capsule around the testis, and a reflection of this capsule along the posterior border (the mediastinum testis) runs along the superior inferior axis of the testis.
The shunt surgeries provide an opening in the tunica albuginea
of the cavernosal body and corpus spongiosum or a vein for blood drainage.
Genisleyen sinuzoidler ile tunika albuginea
arasinda kucuk venullerin kompresyonu, venoz akisin azalmasina, dolayisi ile kanin korpus kavernozum icinde tutulmasina neden olur.
The tunica albuginea
was smooth, pale gray, and glistening, with no evidence of tumor.
1) It usually develops in the air-filled spaces of the middle ear region of the temporal bone; (1) however, it has also been reported in the testis, (3) tunica vaginalis, (4-6) tunica albuginea
, (7) epididymis, (8) and kidney.
13) In contrast to Peyronie's disease that usually is localized at the tunica albuginea
, epithelioid sarcoma shows infiltrating lesions of the corpora cavernosa, and the young age is a risk factor for epithelioid sarcoma that occurred mostly in men under 40 years.
