Summary
This report details a rare case of squamous cell carcinoma (SCC) in a Korean man's testis, likely originating from an epidermal cyst. It is the second reported instance of testicular SCC without a primary tumor elsewhere.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Squamous cell carcinoma (SCC) is a common neoplasm but rare in the testis.
- Testicular SCC typically arises secondary to other primary tumors or inflammation.
Observation:
- A 51-year-old man presented with a two-month history of an enlarged right testis.
- Surgical resection revealed a large, well-circumscribed ovoid mass replacing testicular architecture, with central cystic changes.
Findings:
- Microscopic examination identified moderately differentiated squamous cell carcinoma (SCC) composed of ovoid tumor cells.
- The mass contained laminated keratinous material and a cystic cavity lined by dysplastic squamous epithelium, suggesting origin from an epidermal cyst.
Implications:
- This case represents the second report of testicular SCC in a patient without other primary tumors.
- It is the first documented case of testicular SCC in Korea, highlighting its rarity and potential origins.

01:20Disorders of the Male Reproductive System
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:27Testes: Histology
A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.

01:19Testes: Gross Anatomy
The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...
