What should you know about granuloma annulare subcutaneous?

Unlike the common surface pattern, subcutaneous granuloma annulare is located in deeper skin or the tissue just beneath it. The lumps may feel firm, smooth and mobile, and the overlying skin may look normal or only slightly changed. They can occur near the scalp, hands, feet or lower legs, particularly in children, although any new deep lump deserves an appropriate assessment. The appearance can overlap with cysts, lipomas, inflamed nodules or other growths, so touch and location alone cannot establish the diagnosis.

Arrange a dermatology visit rather than squeezing or repeatedly pressing the lump. The clinician may measure it, examine nearby skin and decide whether imaging or a biopsy would clarify its depth and nature. Treatment depends on the diagnosis, size, site and symptoms. Some lesions can be observed; others may need a procedure or anti-inflammatory treatment. Topical medicine may not reach a deep nodule, while an intralesional steroid injection is a clinician-delivered option that can be discussed when suitable. Learn about [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) and [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/).

Seek timely assessment if a lump grows, becomes fixed, painful, warm, red or soft in the centre, or begins draining. Prompt care is also appropriate for fever, several rapidly appearing lumps, numbness, or difficulty moving a nearby joint. These changes can reflect infection or another process rather than a quiet granuloma annulare nodule.

Ask how deep the lump seems, whether a biopsy or scan is useful, and what changes should trigger an earlier review. Ask whether observation is reasonable, how the diagnosis differs from a cyst or lipoma, and whether an injection would reach the affected tissue.
