Differential Diagnosis for Penis Lump around Neck of Glans, Red, Swelling
- Single most likely diagnosis
- Phimosis: This condition is characterized by the inability to retract the foreskin over the glans penis, which can lead to swelling, redness, and a lump-like appearance around the neck of the glans due to accumulated smegma or poor hygiene.
- Other Likely diagnoses
- Balanitis: An inflammation of the glans penis, often caused by poor hygiene, infections, or allergies, which can present with redness, swelling, and a lump around the neck of the glans.
- Penile cysts or abscesses: These can form around the neck of the glans due to blocked sebaceous glands or infections, leading to a lump, redness, and swelling.
- Smegma accumulation: Smegma is a substance that can accumulate under the foreskin, causing irritation, redness, and swelling, which may be perceived as a lump around the neck of the glans.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Penile cancer: Although rare, penile cancer can present with a lump, redness, and swelling around the glans or foreskin, making it crucial to rule out, especially in high-risk individuals or those with persistent symptoms.
- Gangrene or necrotizing fasciitis: Severe infections can lead to gangrene or necrotizing fasciitis, which are medical emergencies requiring immediate attention. Symptoms can include severe pain, redness, swelling, and a lump, particularly if there's a history of trauma or infection.
- Rare diagnoses
- Lymphogranuloma venereum (LGV): A sexually transmitted infection caused by certain strains of Chlamydia trachomatis, which can lead to swelling, redness, and lymphadenopathy, including around the genital area.
- Kaposi's sarcoma: A type of cancer that can affect the skin and other organs, often associated with immune suppression (e.g., HIV/AIDS), which can present with lesions or lumps on the penis, including around the glans.
