Penis navicular fossa cancer is a rare type of penile cancer that affects the navicular fossa, the bulbous part of the urethra located at the tip of the penis. Understanding this condition is crucial for early detection and effective treatment. This guide provides an in-depth look into penis navicular fossa cancer, covering definitions, causes, symptoms, diagnostic methods, treatments, prevention, and frequently asked questions.
Penis navicular fossa cancer refers to malignant tumors that develop in the navicular fossa region of the penis. This area is part of the urethral meatus, the external opening through which urine and semen exit the body. Cancer here is uncommon but requires prompt medical attention due to its sensitive location and potential impact on urinary and sexual functions.
Pathophysiology
Structure
- Navicular Fossa: The distal part of the male urethra, located just behind the glans penis.
- Penis Anatomy: Comprises the shaft, glans, and the urethral meatus (navicular fossa).
Blood Supply
- Arteries: Primarily supplied by the dorsal arteries of the penis, including the deep and superficial arteries.
- Veins: Drainage occurs through the dorsal venous system.
Nerve Supply
- Sensory Nerves: Provide sensation to the glans and navicular fossa.
- Autonomic Nerves: Control involuntary functions like erection and ejaculation.
Types of Penis Navicular Fossa Cancer
- Squamous Cell Carcinoma: Most common type, arising from the flat cells lining the navicular fossa.
- Adenocarcinoma: Originates from glandular cells.
- Basal Cell Carcinoma: Rare, originating from basal cells.
- Melanoma: Extremely rare, arising from pigment-producing cells.
