___________________
the more common of the two, occurs in approximately 1 in 300 live male births. [59]

Even when
isolated, these urethral defects may have clinical significance, because the abnormal opening is
often constricted
, resulting inurinary tract obstructionand anincreased risk of ascending
urinary tract infections. \

When the orifices are situated near the base of the penis, normal
ejaculation and insemination are hampered or totally blocked. These lesions therefore are
possible causes of sterility in men.

Phimosis is important because _________________

Q

Most cases of Balanoposthitis occur as a consequence________________, with accumulation of desquamated epithelial cells, sweat, and
debris, termed smegma, acting as local irritant. Persistence of such infections leads to inflammatory scarring and, as mentioned earlier, is a common cause of phimosis.

A

** type 6**

17
Q

Condylomata acuminata may occur on the____________ and ___________

A

external genitalia or perineal areas.

18
Q

In the Condyloma acuminatum on the penis these lesions occur most often about the_________________

.

A

coronal sulcus and inner surface of
the prepuce

19
Q

In condyloma acuminatum located in the coronal sulcus and inner surface of the prepuce they consist of_________________ ( Fig. 21-15 ).

A

single or multiple sessile or pedunculated, red papillary
excrescences that vary from 1 mm to several millimeters in diameter

20
Q

WHat is the histological appearance of Condylomata acuminatum?

A

Histologically a branching, villous, papillary connective tissue stroma is covered by epithelium
that may have considerable superficial hyperkeratosis and thickening of the underlying
epidermis (acanthosis) (
Fig. 21-16 ).

The normal orderly maturation of the epithelial cells is
preserved
.

21
Q

______________________characteristic of
HPV infection, is noted in these lesions ( Fig. 21-17 )

. Cells may have degenerative (viral)
atypia but true dysplasia is rare.

Condylomata acuminata tend to recur but only rarely
progress into in situ or invasive cancers.

A

Cytoplasmic vacuolization of the squamous cells (koilocytosis),

22
Q

Carcinoma in Situ (CIS)
In the external male genitalia, two distinct lesions display histologic features of CIS: _____________ and __________

A
  1. Bowen
    disease
  2. and bowenoid papulosis.
23
Q

CIS lesions have a strong association with infection by
_____________________

A

HPV, most commonly type 16.

24
Q

_______________ occurs in the genital region of both men and women, usually in those over the
age of 35 years
.

In men it tends to involve the skin of the shaft of the penis and the scrotum.

A

Bowen disease

25
Q

What is the appearance of Bowen disease grossly?

A

Grossly it appears as a:

  • solitary,
  • thickened,
  • gray-white,
  • opaque plaque.

It can also manifest on the glans and prepuce:

  • as single or multiple shiny red,
  • sometimes velvety plaques.
26
Q

What is the appearance of Bowens disease histologically?

A
  • the epidermis shows proliferation with **numerous mitoses, some atypical. **
  • The cells are** markedly dysplastic with large hyperchromatic nuclei**
  • and lack of orderly maturation ( Fig. 21-18 ).
  • Nevertheless, the** dermal-epidermal border is sharply delineated by an intact basement membrane. **
27
Q

_______________ occurs in sexually active adults.

A

Bowenoid papulosis

28
Q

What is the clinically difference of Bowenoid papuloisis from Bowens disease?

A

it differs from Bowen disease by
the younger age of patients and the presence of multiple (rather than solitary) reddish brown
papular lesions
.

29
Q

Histologically, bowenoid papulosis is indistinguishable from Bowen disease and
is also related to HPV type 16.

However, in contrast to Bowen disease, bowenoid papulosis
virtually never develops into an_________________

A
    • invasive carcinoma and in many cases spontaneously
      regresses. **

**” **So tandaan.. Bowenoid papulosis doesnt result to invasive CA and usually it REGRESS!”

30
Q

_____________of the penis is an uncommon malignancy in the United States,
accounting for fewer than 1% of cancers in males

. By contrast, in some parts of Asia, Africa,
and South America the incidence of squamous cell carcinoma of the penis ranges from 10% to
20% of male malignancies
.

A

Squamous cell carcinoma

31
Q

What is the explanation why SCCA in penis ranges from 10 to 20 percent in other parts of the world like in Asia and Africa in contrast to the USA.

A

Circumcision confers protection, and hence this cancer is extremely
rare among Jews and Moslems
and is correspondinglymore common in populations in which
circumcision is not routinely practiced
.

It is postulated that circumcision is associated with better
genital hygiene,
which, in turn,reduces exposure to carcinogensthatmay be concentrated in
smegma
anddecreases the likelihood of infection with potentially oncogenic types of HPV.

HPV DNA can be detected in **penile squamous cancer in approximately 50% of patients. [62] HPV
type 16
is the
most frequent culprit**, but HPV 18 is also implicated.

Cigarette smoking elevates
the risk of developing cancer of the penis. [63] Carcinomas are usually found in patients
between the ages of 40 and 70.

32
Q

What are the Clinical Features of SCCA in Penis?

A

Invasive squamous cell carcinoma of the penis is a:

  • slowly growing, locally invasive lesion that
  • often has been present for a year or more before it is brought to medical attention. [66]

The lesions are nonpainful until they undergo secondary ulceration and infection.

33
Q

Metastases to inguinal lymph nodes characterize the early stage, but widespread dissemination is extremely
uncommon until the lesion is far advanced.

Clinical assessment of regional lymph node
involvement is notoriously inaccurate; **50% of men with penile squamous cell carcinoma and
clinically enlarged inguinal nodes have only reactive lymphoid **hyperplasia when examined
histologically.

The prognosis is related to the stage of the tumor.

In persons with limited lesions
without invasion of the inguinal lymph nodes, there is a 66% 5-year survival rate, whereas
metastasis to the lymph nodes carries a grim 27% 5-year survival.
