Differential Diagnosis for Swelling and Redness in Penis with Band of Constrictive Tissue
- Single most likely diagnosis
- Peyronie's Disease: This condition is characterized by the formation of fibrous scar tissue, leading to a band of constrictive tissue that can cause swelling, redness, and curvature of the penis. The presence of a band of constrictive tissue behind the glans is a hallmark of this disease.
- Other Likely diagnoses
- Paraphimosis: This condition occurs when the foreskin is retracted behind the glans and cannot be returned to its original position, leading to swelling, redness, and constrictive tissue. It is a common condition that can cause the symptoms described.
- Phimosis: This condition is characterized by a tight foreskin that cannot be retracted over the glans, leading to swelling, redness, and constrictive tissue. It is another possible cause of the symptoms.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Penile Cancer: Although rare, penile cancer can cause swelling, redness, and constrictive tissue. It is essential to rule out this condition, as it can be life-threatening if left untreated.
- Necrotizing Fasciitis: This is a rare but life-threatening condition that can cause swelling, redness, and tissue necrosis. It requires prompt medical attention to prevent serious complications.
- Rare diagnoses
- Dupuytren's Contracture of the Penis: This is a rare condition characterized by the formation of fibrous tissue in the penis, leading to curvature and constrictive tissue.
- Kaposi's Sarcoma: This is a rare type of cancer that can cause swelling, redness, and constrictive tissue in the penis, particularly in immunocompromised individuals.
