Black Growth on the Neck: What to Know

Colour alone cannot identify a skin growth. Possibilities include a pigmented mole, a skin tag that has twisted and lost its blood supply, a blocked pore, an inflamed lump, or another skin lesion. A clinician may inspect it with magnification and decide whether sampling or removal is appropriate.

Notice whether the growth sits on the surface or beneath the skin, and whether it feels soft, firm, rough, or fluid-filled. A boil commonly presents as a tender, inflamed lump and may develop drainage. Basal cell carcinoma can present as a persistent growth or sore, sometimes with crusting or bleeding; it is not diagnosed by dark colour alone.

Photographs taken in consistent lighting can help show change. Do not squeeze, cut, tie off, or apply corrosive products to the growth, because this can cause bleeding, infection, burns, and delayed diagnosis.

Arrange a routine medical appointment if the growth is unexplained or persists. Before the visit, record when you first noticed it, whether it changed in colour or size, and whether clothing, shaving, or jewellery irritates it. Mention previous skin cancers, immune suppression, and medicines that affect bleeding.

Treatment depends on the diagnosis. Some harmless growths need no treatment; others may be removed or sampled. A steroid injection into the skin is useful only for selected inflammatory or scar-related lesions and should not be used before the diagnosis is clear.

Seek prompt assessment if the growth is rapidly changing, repeatedly bleeding, ulcerated, producing pus, or surrounded by spreading redness. Fever, severe pain, red streaking, facial or neck swelling, difficulty swallowing, or difficulty breathing warrants urgent medical care.

Ask what diagnosis fits the examination, whether dermoscopy or a biopsy is needed, what changes should trigger an earlier return, and whether removal could leave a scar or pigment change. Also ask how to protect the area from friction while waiting for treatment.
