Are subcutaneous nodules cancerous?
The differential diagnosis of a subcutaneous nodule is extensive and mostly benign, including traumatic, infectious, inflammatory, and neoplastic etiology. Metastasis to soft tissue, defined as metastasis to skeletal muscle, skin, and subcutaneous tissues, has only rarely been reported [4].
What do subcutaneous nodules mean?
A well circumscribed lump of tissue, firm to touch, typically non-tender, predominantly occurring as a cutaneous manifestation of rheumatoid arthritis localized to extensor surfaces near joints, but may be internal. Knuckle pads.
Are subcutaneous nodules painful?
Abnormal bumps or masses (nodules) appear in the fatty layer under the skin (subcutaneous fat) of the legs, thighs and buttocks. In some patients, the arms, abdomen, and/or face may be involved. These nodules are usually 1-2 centimeters wide and may be either painful and tender or painless.
What diseases cause subcutaneous nodules?
Only two storage diseases, multicentric reticulohistiocytosis and Farber disease, cause both subcutaneous nodules and arthritis. The bacterial pathogens producing nodules and arthritis include the treponemal organisms, syphilis, yaws, and pinta, as well as leprosy.
Do nodules go away?
Mostly, nodules disappear on their own or stay the same size. Nodules are not dangerous and require no treatment as long as they don’t grow. Otherwise, your doctor may suggest treatments to shrink thyroid nodules.

What does a nodule look like?
Commonly called a “spot on the lung” or a “shadow,” a nodule is a round area that is more dense than normal lung tissue. It shows up as a white spot on a CT scan. Lung nodules are usually caused by scar tissue, a healed infection that may never have made you sick, or some irritant in the air.
Is there a difference between a nodule and a tumor?
What is the difference between a nodule and cyst?
If the cells have invaded the surrounding tissue, the diagnosis is cancer. Thyroid cysts are nodules filled with fluid. If a nodule has both fluid and solid parts, it is called a complex nodule. They need to be surgically removed if they cause neck pain or difficultly swallowing.
How do you get rid of skin nodules?
Each laser has specific uses.
- Laser excision can remove:
- Cryotherapy is a method of super-freezing tissue in order to destroy it. It is most commonly used to destroy or remove warts, actinic keratoses, seborrheic keratoses, and molluscum contagiosum.
- Mohs surgery is a way to treat and cure certain skin cancers.
What causes fibrous nodules?
Nodules appear after trauma and with such general systemic diseases as syphilis, yaws, leprosy, scleroderma, rheumatic fever, rheumatoid arthritis and acrodermatitis chronica atrophicans.
Is a nodule the same as a tumor?
What is a subcutaneous lesion?
Subcutaneous nodules are deep-seated lesions in the skin, located in the deep dermis and subcutis, often with minimal changes appreciated on the surface of the skin. They are often easier to feel than see.
What is a cutaneous nodule?
The term “subcutaneous nodule” is a medical phrase that can cover basically any sort of lump or bump that occurs beneath the skin. These bumps are noticeable and can be felt on the surface, but they aren’t skin blemishes in and of themselves the way warts and most moles are.
What are skin nodules?
Skin nodules. Skin nodules are solid or cystic raised bumps in the skin that are wider than 1 centimeter (cm), but less than 2 cm.
