Differential Diagnosis for Swelling of Coronal Sulcus
Single Most Likely Diagnosis
- Balanitis: This is an inflammation of the glans penis, which can cause swelling and tenderness in the coronal sulcus area. It's more common in uncircumcised males but can occur in circumcised males as well, especially if there's poor hygiene or an allergic reaction.
Other Likely Diagnoses
- Phimosis: Although less common in circumcised males, if the circumcision is incomplete or there's scarring, it can lead to phimosis, causing swelling and discomfort.
- Contact Dermatitis: An allergic reaction or irritation from soaps, condoms, or other products can cause dermatitis around the glans and coronal sulcus.
- Urethritis: Inflammation of the urethra can cause discomfort and swelling around the glans, including the coronal sulcus, and is often accompanied by symptoms like dysuria.
Do Not Miss Diagnoses
- Testicular Torsion: Although the primary symptom is testicular pain, it can sometimes radiate to the groin and be associated with swelling in the genital area. It's a medical emergency requiring immediate attention.
- Epididymitis: Inflammation of the epididymis can cause severe pain and swelling that might be felt in the groin and could potentially cause swelling around the base of the penis, including the coronal sulcus area.
- Fournier's Gangrene: A severe and potentially life-threatening condition involving necrotizing fasciitis of the genitalia. Early signs can include swelling, redness, and pain in the genital area.
Rare Diagnoses
- Penile Cancer: Although rare, any unexplained swelling or lesion on the penis should be evaluated for the possibility of cancer, especially in older adults or those with a history of HPV.
- Granuloma Inguinale (Donovanosis): A bacterial infection that can cause ulcerative lesions on the genitals, which might be accompanied by swelling in the affected area.
- Lymphogranuloma Venereum (LGV): A sexually transmitted infection that can cause lymphadenopathy and swelling in the genital area, including the possibility of swelling around the coronal sulcus due to secondary infection or inflammation.
