Differential Diagnosis for Penile Pain and Swelling
- Single most likely diagnosis
- Paraphimosis: This condition is characterized by the retraction of the foreskin behind the glans penis, which can cause swelling, pain, and redness. The presence of a band of constrictive tissue behind the glans and the patient being uncircumcised supports this diagnosis.
- Other Likely diagnoses
- Gonorrhea: As a sexually transmitted infection, gonorrhea can cause penile discharge, pain, and swelling, especially in a recently sexually active individual.
- Hydrocele: Although less likely given the acute presentation and associated symptoms, a hydrocele (fluid accumulation around a testicle) could potentially cause swelling, but it's more commonly associated with the scrotum rather than the penis itself.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Necrotizing fasciitis: Although rare, this is a severe infection that can quickly progress and is life-threatening. The presence of severe pain, swelling, and redness could be indicative of this condition, especially if the patient's condition rapidly deteriorates.
- Priapism: This condition involves a prolonged erection that can cause pain and swelling. If not promptly treated, it can lead to permanent damage.
- Rare diagnoses
- Varicose veins: While varicose veins can occur in the scrotum (varicocele), they are less commonly associated with the penis itself and would not typically cause acute pain and swelling.
- Inguinal hernia: Although an inguinal hernia can cause swelling in the groin area, it is less likely to cause pain and swelling localized to the penis.
