Penile Subcutaneous Granuloma Annulare

Subcutaneous granuloma annulare forms deeper than a surface rash, so it may feel firm and smooth while the overlying skin looks close to normal. It is an inflammatory skin condition, not a sign that the skin is infected. A penile lump can have other causes, however, including a cyst or another benign growth. Location, firmness, mobility, duration, and changes in the covering skin help a dermatologist decide whether observation is reasonable or whether a biopsy is needed for confirmation.

Do not squeeze, puncture, or repeatedly handle the nodule. Use gentle washing and avoid friction if the area is tender. If the diagnosis is confirmed, some people need observation because a stable, symptom-free lesion may not require treatment. When treatment is wanted or symptoms persist, options can include [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) in selected situations or a [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/). A clinician will weigh the thin, sensitive nature of penile skin when choosing treatment.

Arrange review for any new penile lump, particularly one that grows, becomes painful, ulcerates, bleeds, drains, or changes colour. Seek prompt care for fever, rapidly increasing swelling, severe pain, or difficulty urinating. A lump that seems harmless still deserves an examination if it does not settle or if its diagnosis is uncertain; treatment should follow identification rather than guesswork.

Ask whether the nodule is superficial or subcutaneous, how confident the diagnosis is, whether observation or biopsy is appropriate, and what side effects a cream or injection could cause on penile skin.
