Carcinoma Penis

Introduction

--- Content provided by⁠ FirstRanker.com ---

Uncommon malignancy in developed countries

Higher incidence rates are seen in Africa and Asia (10%

to 20%)

--- Content provided by FirstRanker.com ---


Commonly affects those between 50 and 70 years of

age

--- Content provided by​ FirstRanker.com ---

22% of patients are less than 40 years of age


Epidemiology
? Intact foreskin

--- Content provided by‍ FirstRanker.com ---


? Phimosis (25%)

? Precancerous lesions are found in 15%-20% of patients

--- Content provided by‌ FirstRanker.com ---

? Human papilloma virus(HPV 16,18)

? Chronic inflammatory conditions (eg, balanoposthitis and
lichen sclerosus et atrophicus)

--- Content provided by⁠ FirstRanker.com ---

Premalignant lesions
Pathology
? Primary malignancies (those that originate from either the
soft tissues, urethral mucosa, or covering epithelium)

--- Content provided by‌ FirstRanker.com ---

? Secondary malignancies (ie, those that represent

metastatic disease and often affect the corpus

cavernosum

--- Content provided by​ FirstRanker.com ---


? MC: squamous cell carcinoma is found on
glans: 48%,prepuce: 21%,glans & prepuce:9%,coronal

sulcus: 6%, and shaft: <2%

? Primary, non squamous malignancies comprise <5% of

penile cancers.

--- Content provided by​ FirstRanker.com ---

cancers, followed by melanomas, basal cell carcinomas,

and lymphomas

Treatment of the Primary Lesion

? Small tumors limited to foreskin:

--- Content provided by⁠ FirstRanker.com ---

Circumcision alone, especially with tumors in the proximal

foreskin, may be associated with recurrence rates of 32%

? Small superficial penile cancers:

--- Content provided by FirstRanker.com ---

? Moh's micrographic surgery
? Radiation therapy (EBRT/brachytherapy)
? RT has yielded local control rates similar to surgical resection:

? Carcinomas involving the glans & distal shaft:

--- Content provided by⁠ FirstRanker.com ---

? partial penectomy excising 1.5 to 2 cm of

normal tissue proximal to the margin of the tumor.

This should leave a 2.5- to 3-cm stump of penis

penis:
