Granulomatous reactions A foreign body reaction to pigment may cause raised red bumps at the site of the tattoo that are made up of epithelioid cells, lymphocytes and a few giant cells.
Granulomas may or may not cause symptoms. Some individuals may have granulomas without noticeable effects, while others may experience symptoms such as skin changes, pain, or discomfort depending on the location and underlying cause.
Treatment of granulomatous reactions to tattoos has variable success. Topical or intralesional corticosteroid injection or laser ablation may be beneficial; however, these treatments may cause areas of hypopigmentation or scarring within the tattoo. Some reactions may resolve spontaneously.
Treatment might clear the skin gradually, but the bumps tend to come back. Untreated, the condition might last from a few weeks to decades.
Granuloma annulare is often mistaken for ringworm. Ringworm, however, is usually scaly and itchy. Granuloma annulare is not. This rash can also be mistaken for bug bites or a rash caused by a tick with Lyme disease.
Pyogenic granuloma of the skin presents as a painless red fleshy nodule, typically 5-10mm in diameter, that grows rapidly over a few weeks. The surface is initially smooth but can ulcerate, become crusty, or verrucous. Pyogenic granuloma is usually solitary, but multiple nodules and satellite lesions can erupt.
Granuloma annulare is a skin condition that often looks like a ring of bumps. It sometimes clears up without treatment, but it can take a long time and it may come back. See a GP if you have bumps or lumps on your skin that do not go way in a few weeks.
A granuloma is a tiny cluster of white blood cells and other tissue. It can be found in the lungs, skin or other parts of the body. They form as a reaction to infections, inflammation, irritants or foreign objects.
Nevertheless, the best understood function of granulomas is their role in protection against chronic infection. The process of granuloma formation can be divided into four phases: initiation, accumulation, effector, and resolution (Fig. 1).
Granuloma inguinale (donovanosis) is a sexually transmitted infection (STI) caused by a bacterial infection of your genitals. In rare cases, a person can also contract it through skin-to-skin contact. Granuloma inguinale is rare in the U.S. but is still found in tropical and subtropical countries.
Granulomatous reactions
A foreign body reaction to pigment may cause raised red bumps at the site of the tattoo that are made up of epithelioid cells, lymphocytes and a few giant cells.
Foreign body granulomas occur several months to years after injection at all implantation sites at the same time. Without treatment, they may grow to the size of beans, remain virtually unchanged for some years, and then resolve spontaneously.
If you're having an allergic reaction to your tattoo, you might get a rash that's red, bumpy, or itchy. These symptoms can crop up in the days after you first get your tattoo or can appear months or years later. You can most likely treat the area with a steroid ointment.
Granulomas often don't cause symptoms on their own. For those who do have symptoms, they depend on where in your body the granuloma forms. You may also have symptoms of an infection that causes granulomas.
You apply petroleum jelly (for example, Vaseline®) around the pyogenic granuloma to protect your skin and then sprinkle table salt on to the lump. You can then cover the area with a plaster and repeat every day until the salt dries out the lump and makes it shrink down.
In about two or three days you should notice that the granuloma reduces in size. It may change colour, dry off and the area will gradually heal.
Pyogenic granulomas tend to ooze, and they break and bleed easily.
Most granulomas fall into one of two categories: caseating, with a necrotic center, or non-caseating, without any necrosis. Caseating granulomas are often caused by infections, while the non-caseating type is typically caused by an inflammatory condition.
Granuloma annulare often has a brownish-red color. The typical lesions of granuloma annulare are ring-like, brownish-red, and slightly elevated lesions. This image displays ring-like, non-scaling, slightly elevated lesions typical of granuloma annulare.
Nummular eczema is a skin condition that causes circular, raised spots on your skin. Nummular comes from a Latin word for “coin,” and the patches are coin-shaped. The lesions are often itchy, sometimes ooze clear fluid and may become crusty on top.
Some research suggests that chronic stress may cause granuloma annulare. Reducing your stress may help prevent granuloma annulare.
Noncalcified granulomas do not contain calcium deposits. They have a diffuse appearance. Because of this, they are often misdiagnosed as cancer growths. Calcified granulomas are denser and will therefore appear more brightly than the surrounding soft tissue on an X-ray or CT scan.
Key points about granuloma annulare
The rash is most often red and raised, and roughly in the shape of a ring. The rash may be on just one part of the body. Or it may appear on more than one area of the body. In some cases, it may itch.
An important feature of granulomas is whether or not they contain necrosis, which refers to dead cells that, under the microscope, appear as a mass of formless debris with no nuclei present.
