Yes, scrotal cysts are absolutely possible in a 28-year-old man and represent a common benign finding.
Scrotal cysts, particularly epidermal inclusion cysts (also called epidermoid or sebaceous cysts), are well-documented benign lesions that frequently occur in young and middle-aged men, including those in their late twenties 1, 2, 3, 4. These are among the most common scrotal masses in this age group.
Types of Scrotal Cysts
The most common cystic lesions in the scrotum include:
- Epidermal inclusion cysts (epidermoid cysts): Benign lesions lined by stratified squamous epithelium containing keratin material 1, 2, 3
- Sebaceous cysts: Similar benign encapsulated nodules filled with keratin debris and cholesterol 4
- Testicular epidermoid cysts: Less common, occurring within the testis itself rather than scrotal skin 5, 6
Clinical Presentation
Scrotal cysts typically present as:
- Painless, slowly growing nodules or masses
- Firm, smooth-surfaced swellings
- Single or multiple lesions
- Can range from small to large (cases up to 9 cm documented) 1
- Usually benign appearance without overlying skin inflammation
Important caveat: While most grow slowly over months to years, rare cases can demonstrate rapid enlargement over weeks to months, which may mimic malignant pathology 1.
Recommended Diagnostic Approach
Ultrasound of the scrotum (with or without Doppler) is the appropriate initial imaging modality for any newly diagnosed palpable scrotal abnormality 7. This is the standard of care regardless of patient age or history.
Key ultrasound findings for cysts:
- Well-circumscribed lesions
- Ability to distinguish intratesticular vs. extratesticular location (98-100% accuracy) 7
- Cystic appearance with characteristic features
- US is nearly 100% sensitive for detecting intrascrotal masses 7
Critical Distinction Required
The ultrasound evaluation must determine:
- Location: Is the cyst in the scrotal skin/subcutaneous tissue (benign) or within the testis itself?
- Characteristics: Purely cystic vs. solid or mixed components
Any solid or mixed cystic-solid intratesticular mass requires surgical exploration to exclude malignancy, as testicular cancer is the most common malignancy in men aged 20-34 years 7. However, purely extratesticular (scrotal wall) cysts are benign.
Management
- Benign scrotal skin cysts: Surgical excision only if symptomatic, infected, or cosmetically concerning 2, 4
- Intratesticular cysts with benign imaging features: May be candidates for testis-sparing surgery with intraoperative frozen section 6
- Suspicious intratesticular masses: Require inguinal orchiectomy 7, 6
The bottom line: A 28-year-old man can absolutely develop a scrotal cyst—it's a common benign condition in this age group. However, proper ultrasound evaluation is essential to distinguish benign scrotal wall cysts from potentially malignant intratesticular masses.
