Q

Campbell review TRUE statements:

A

Cancer may develop anywehere on the penis
Phimosis may obscure the nature of the lesion
Penetration of Buck fascia and tunica albuginea –> permits invasion of the vascular corpora
Cancer cells reach contralateral inguinal region –> lymphatic cross communications at the base of the penis

Q

Penile cancer initial spread: ___

A

Metastasis initially involves inguinal lymph nodes above the fascia lata

The lymphatics of the prepuce form a connecting network that joins with the lymphatics from the skin of the shaft. These tributaries drain into the superficial inguinal nodes (the nodes external to the fascia lata)

Q

Hypercalcemia in penile cancer

A

Parathyroid hormone-like substances released from the tumor. Parathyroid hormone and related substances may be produced by both tumor and metastases that activate osteoclastic bone resorption.

Q

Bushcke-Lowenstein tumor vs. condyloma acuminatum

A

The Buschke-Löwenstein tumor differs from condyloma acuminatum in that condylomata, regardless of size, always remain superficial and never invade adjacent tissue.

Buschke-Löwenstein tumor displaces, INVADES, and destroys adjacent structures by compression. Aside from this unrestrained local growth, it demonstrates no signs of malignant change on histologic examination and does not metastasize.

Q

Mohs Micrographic Surgery

A

• Mohs surgery is an alternative to wide local excision in select cases.
Thin layers of cancerous skin are excised and viewed microscopically until a tissue layer is negative for the tumor.
Allows for increased precision, though the success rate declines with higher stage disease.
• May be preferable for a small superficial lesion on the proximal shaft to avoid total penectomy for an otherwise fairly low-risk lesion.

Q

Surgical management for inguinal and pelvic LNs

A

Standard or modified ILND or DSNB is indicated in patients with penile cancer in the absence of palpable inguinal adenopathy if high-risk
features for nodal metastasis are seen in the primary penile tumor: Lymphovascular invasion
≥pT1G3 or ≥T2, any grade
>50% poorly differentiated
• DSNB is only recommended if the treating physician has experience with this modality.
• If positive lymph nodes are found on DSNB, ILND is recommended.
• PLND should be considered at the time or following ILND in patients with ≥2 positive inguinal nodes on the ipsilateral ILND site or in the
presence of extranodal extension on final pathologic review.
• A bilateral PLND should be considered either at the time or following ILND in patients with ≥4 positive inguinal nodes (in total among both
sides).1

Apex of triangle → apex of femoral triangle

Sartorious flap: detached from ASIS to cover femoral vessels
