But not everything that feels like \u201ca little ball of fat\u201d is a lipoma: the <b>nodules of lipedema<\/b>, a cyst, an inflamed vein or a lymph node can feel similar, and each is handled very differently.<\/p>\n\n<p>Below we explain how any lump is sorted using <b>six examination questions<\/b>, what the lipedema clinical guideline actually says about the so-called \u201cnodules\u201d and, before anything else, <b>which features mean you should see a doctor soon<\/b>.<\/p>\n\n<h2><b>First, the signs that mean you should see a doctor soon<\/b><\/h2>\n\n<p>The vast majority of soft tissue lumps turn out to be benign, and many are lipomas. Even so, the UK sarcoma guidelines state that a lump with any of these three features should be investigated <b>as if it were malignant until proven otherwise<\/b>: it is growing, it is larger than 5 cm, or it is painful. The more of them that occur together, the higher the risk, and <b>growth is the single sign that carries most weight<\/b> on its own. <b>Book an appointment with your doctor this week<\/b>, rather than waiting to see what happens, if you notice:<\/p>\n\n<ul>\n<li><p><b>A lump that is growing<\/b>, even if it does not hurt. This is the sign that carries most weight.<\/p><\/li>\n<li><p><b>A lump larger than 5 cm<\/b> (about 2 inches) across.<\/p><\/li>\n<li><p><b>A lump that is hard, deep or fixed<\/b>, and does not move when you push it with your fingers. The deeper a lump sits, the more likely it is to be a sarcoma.<\/p><\/li>\n<li><p><b>A lump that hurts<\/b> persistently, or one that <b>comes back<\/b> after being removed.<\/p><\/li>\n<li><p><b>Enlarged lymph nodes in the groin<\/b> together with fever, night sweats or unexplained weight loss.<\/p><\/li>\n<\/ul>\n\n<p>And <b>seek medical attention the same day<\/b> if a <b>red, hot, painful cord<\/b> appears along a vein, especially above the knee, or if the whole leg suddenly swells: a superficial thrombosis can extend into the deep veins.<\/p>\n\n<h3><b>What does a hard lump in the leg mean?<\/b><\/h3>\n\n<p>Hard is a description, not a diagnosis. It can be a tense cyst, an inflammatory nodule such as those of erythema nodosum, a hematoma that is organizing or, much less often, a soft tissue tumor. What changes the urgency is not hardness alone, but whether the lump is <b>fixed, deep or growing<\/b>. A hard lump with any of those three features is assessed with an ultrasound scan, not by touch.<\/p>\n\n<h2><b>The six questions that sort any lump<\/b><\/h2>\n\n<p>Before putting a name to it, whoever examines you works through six questions: how it <b>feels<\/b>, whether it <b>moves<\/b>, whether it <b>hurts<\/b>, <b>how many<\/b> there are, whether they are <b>symmetrical<\/b> and how they have <b>changed over time<\/b>. Taken together, they separate the most common conditions fairly well.<\/p>\n\n<table>\n<thead>\n<tr><td><strong>Condition<\/strong><\/td><td><strong>Feel<\/strong><\/td><td><strong>Mobility<\/strong><\/td><td><strong>Pain<\/strong><\/td><td><strong>Number and symmetry<\/strong><\/td><td><strong>Course<\/strong><\/td><\/tr>\n<\/thead>\n<tbody>\n<tr><td><p><b>Lipoma<\/b><\/p><\/td><td><p>Soft, well defined<\/p><\/td><td><p>Slides under the skin<\/p><\/td><td><p>Usually not<\/p><\/td><td><p>One, or a few with no pattern<\/p><\/td><td><p>Grows slowly over years, then stabilizes<\/p><\/td><\/tr>\n<tr><td><p><b>Angiolipoma<\/b><\/p><\/td><td><p>Similar to a lipoma<\/p><\/td><td><p>Similar to a lipoma<\/p><\/td><td><p>Can hurt: one of the causes of a painful lipoma<\/p><\/td><td><p>One or several<\/p><\/td><td><p>Slow<\/p><\/td><\/tr>\n<tr><td><p><b>Lipedema<\/b><\/p><\/td><td><p>Dense fatty tissue, sometimes with a fine granular feel<\/p><\/td><td><p>No lump to move: it is a diffuse enlargement<\/p><\/td><td><p>Yes, to pressure: it is the key symptom<\/p><\/td><td><p>Symmetrical in both legs (or in the arms), with the feet spared<\/p><\/td><td><p>Variable; does not worsen as a rule<\/p><\/td><\/tr>\n<tr><td><p><b>Dercum&rsquo;s disease<\/b><\/p><\/td><td><p>Fatty deposits, diffuse or nodular<\/p><\/td><td><p>Variable<\/p><\/td><td><p>Severe, chronic pain<\/p><\/td><td><p>Multiple, mainly on the trunk, the upper parts of the limbs and the arms<\/p><\/td><td><p>Persistent<\/p><\/td><\/tr>\n<tr><td><p><b>Erythema nodosum<\/b><\/p><\/td><td><p>Firm, deep, with red skin on top<\/p><\/td><td><p>Barely mobile<\/p><\/td><td><p>Yes, to touch<\/p><\/td><td><p>Several, mainly on the front of the lower legs<\/p><\/td><td><p>Sudden onset; clears without scarring<\/p><\/td><\/tr>\n<tr><td><p><b>Epidermoid cyst<\/b><\/p><\/td><td><p>Encapsulated nodule just under the skin<\/p><\/td><td><p>Attached to the skin<\/p><\/td><td><p>Variable<\/p><\/td><td><p>One, anywhere on the body<\/p><\/td><td><p>Slow; can last for years<\/p><\/td><\/tr>\n<tr><td><p><b>Varicose vein or thrombophlebitis<\/b><\/p><\/td><td><p>Dilated vein (varicose vein) or a hardened, warm cord (superficial thrombosis)<\/p><\/td><td><p>Follows the course of a vein<\/p><\/td><td><p>Thrombophlebitis does<\/p><\/td><td><p>Follow the veins<\/p><\/td><td><p>Thrombophlebitis appears within days<\/p><\/td><\/tr>\n<tr><td><p><b>Lymph node<\/b><\/p><\/td><td><p>Firm, rounded<\/p><\/td><td><p>Mobile or fixed<\/p><\/td><td><p>Can hurt if it is reactive<\/p><\/td><td><p>In the groin or behind the knee<\/p><\/td><td><p>Reactive nodes usually settle within weeks<\/p><\/td><\/tr>\n<\/tbody>\n<\/table>\n\n<p>No row is a diagnosis, and one finding does not rule out another: a specific lump can coexist with underlying lipedema. The table helps you know <b>what to ask<\/b> at your appointment, not settle the question at home.<\/p>\n\n<p><img loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/lipedemaac.com\/wp-content\/uploads\/2026\/10\/exploracion-palpacion-muslo-consulta.webp\" alt=\"Hands of a female healthcare professional palpating the outer thigh of a patient lying on an exam table during an examination\" title=\"Palpating a lump on the thigh during an examination in consultation\" width=\"1600\" height=\"900\" loading=\"lazy\" decoding=\"async\"><\/p>\n\n<h2><b>Lipoma: the typical fatty lump<\/b><\/h2>\n\n<p>A <b>lipoma<\/b> is a benign tumor made of mature fat cells, almost always surrounded by a thin capsule and sitting just under the skin. It is <b>the most common tumor doctors see<\/b>. Most grow slowly, move when pushed and do not hurt; they feel softer when the muscle underneath is relaxed.<\/p>\n\n<p>They appear most often on the trunk, shoulders, neck and the upper parts of the arms and legs, although they can develop anywhere there is fat. Whether it is a <b>lipoma on the leg<\/b> or elsewhere, the usual pattern is slow growth over years, after which it <b>stays stable<\/b>.<\/p>\n\n<h3><b>Can a lipoma be painful?<\/b><\/h3>\n\n<p>A typical lipoma does not usually hurt. When it does, the most common explanations are that it is <b>pressing on something nearby<\/b> (a nerve, a tendon), that it is a variant called an <b>angiolipoma<\/b>, that it has bled internally, or that it is <b>not actually a lipoma<\/b>. That is why new pain in a lump that used to be quiet is a reason to have it examined again.<\/p>\n\n<h3><b>Does a lipoma need to be removed?<\/b><\/h3>\n\n<p>Not always. A small, superficial, stable lipoma does not usually need treatment. Removal is considered when it is bothersome because of where it is, or when it grows. And there is an important nuance: a lipoma and an <b>atypical lipomatous tumor<\/b> (a form of well-differentiated liposarcoma) are considered <b>distinct entities<\/b>, not a lipoma that \u201cturns bad\u201d. If a lump you were told was a lipoma starts growing quickly, becomes fixed or comes back after removal, the right step is to <b>review the original diagnosis<\/b>.<\/p>\n\n<h2><b>Many lumps at once: lipomatosis and Dercum&rsquo;s disease<\/b><\/h2>\n\n<p>When there is not one lump but many, some rare conditions come into play that are worth knowing by name, because they get confused with lipedema.<\/p>\n\n<h3><b>Why do fatty lumps appear on the arms and legs?<\/b><\/h3>\n\n<p>Several lipomas at once can be due to <b>hereditary multiple lipomatosis<\/b>, with a family history. If they also <b>hurt<\/b>, the name to rule out is <b>Dercum&rsquo;s disease<\/b> (adiposis dolorosa): a rare disorder with multiple painful deposits of subcutaneous fat, diffuse or nodular, mainly on the trunk, the upper parts of the limbs and the arms. It is diagnosed clinically and by exclusion.<\/p>\n\n<p>The difference from lipedema lies in the pattern: lipedema <b>does not affect the trunk<\/b> and is symmetrical in the limbs, whereas Dercum&rsquo;s disease can affect the trunk and is organized around painful deposits. The lipedema guideline itself cites work comparing the two conditions so that they are not confused.<\/p>\n\n<h2><b>Lipedema \u201cnodules\u201d: what they are and why they are not lipomas<\/b><\/h2>\n\n<p>Lipedema (spelled lipoedema in British English) is not a lump: it is a <b>symmetrical, painful enlargement of the fat of the limbs<\/b>. It affects both hips, both thighs or both calves, stops at the ankle and spares the feet and hands, unlike lymphedema, which can affect the foot and toes. To the touch the tissue can feel <b>dense<\/b>, with what many women describe as \u201clittle balls\u201d, and the medical literature refers to <b>firm nodules<\/b> in the subcutaneous fat.<\/p>\n\n<p>Here is what almost no website tells you: the reference clinical guideline (S2k, 2024) states in its <b>Recommendation 2.5<\/b>, with 100% consensus, that the criterion of <b>\u201cnodular\u201d fatty tissue should not be used to diagnose<\/b> lipedema, because it has not been shown to be valid. Feeling a granular texture does not confirm lipedema, and not feeling one does not rule it out.<\/p>\n\n<p>What does count is the whole pattern: <b>symmetry<\/b>, a <b>step change in caliber<\/b> toward the unaffected area and <b>tenderness to pressure<\/b>, which the guideline calls the key symptom. One case often causes confusion: the painful fat pads <b>above and below the knee<\/b>, which the guideline describes as typical of lipedema. Because they form a localized bulge, they are mistaken for a lipoma. But they appear <b>on both knees at once<\/b>, and a single lipoma does not usually do that. The rest of the signs are covered on our page about the <a href=\"\/en\/lipedema-symptoms\/\"><b>symptoms of lipedema<\/b><\/a>.<\/p>\n\n<h3><b>Are painful fatty lumps on the legs lipedema?<\/b><\/h3>\n\n<p>They can be, but only if the pain is in <b>diffuse, symmetrical<\/b> fatty tissue, not in a single lump. A single lump that hurts points to other things: an angiolipoma, an inflamed cyst, an erythema nodosum nodule or a lump that needs an ultrasound scan. In lipedema it is the tissue that hurts when pressed, in both legs and in the same areas, with the feet spared.<\/p>\n\n<h3><b>Why do I have lumps on my legs that do not hurt?<\/b><\/h3>\n\n<p>A soft, mobile lump that does not hurt is, by a wide margin, the description of a <b>lipoma<\/b>. The absence of pain is reassuring, but it does not rule everything out: according to the sarcoma guidelines, the criterion that carries most weight is whether it is <b>growing<\/b>. A lump that does not hurt but is getting bigger, or measures more than 5 cm, should be checked with an ultrasound scan. And lipedema, by definition, does hurt: if the tissue is not tender to pressure, it is not called lipedema.<\/p>\n\n<h3><b>Does the stage of lipedema depend on how many nodules you have?<\/b><\/h3>\n\n<p>The classic stages describe the surface of the skin and the shape of the tissue, but the guideline asks for that classification to be <b>descriptive<\/b> and not used as a measure of severity. And, as we have seen, the nodular tissue criterion should not be used for diagnosis. The stage describes the state of the tissue, not a life sentence. We explain it with our own illustrations in <a href=\"\/en\/stages-of-lipedema\/\"><b>stages and types of lipedema<\/b><\/a>.<\/p>\n\n<h2><b>Lumps that are not fat, even if they look like it<\/b><\/h2>\n\n<p>Some of the \u201cfatty lumps\u201d people ask us about are not fat at all. These are the ones most often confused in the leg:<\/p>\n\n<ul>\n<li><p><b>Erythema nodosum:<\/b> red, firm, deep nodules that are <b>tender to touch<\/b> and appear suddenly, mainly on the front of the lower legs. It is an inflammation of the fat (a panniculitis), more common in women and linked to many possible triggers. It clears without scarring, but the trigger needs to be looked for.<\/p><\/li>\n<li><p><b>Epidermoid cyst:<\/b> a rounded, firm lump attached to the skin and filled with keratin. Often wrongly called a \u201csebaceous cyst\u201d. It is benign and can last for years.<\/p><\/li>\n<li><p><b>Hematoma:<\/b> blood collected after a knock, sometimes inside the muscle, felt as a painful lump. Those caused by an injury are managed with rest and pain relief. If you bruise without any knock, we cover that in <a href=\"\/en\/lipedema-bruising\/\"><b>bruising on the legs with no apparent cause<\/b><\/a>.<\/p><\/li>\n<li><p><b>Lymph nodes:<\/b> in the leg they can be felt in the groin and in the hollow behind the knee, where a Baker&rsquo;s cyst can also appear. As a rough guide, a node is considered enlarged from 1 cm, although the threshold varies by area.<\/p><\/li>\n<\/ul>\n\n<h3><b>Can poor circulation cause lumps on the legs?<\/b><\/h3>\n\n<p>Yes, and they are not fat. A <b>varicose vein<\/b> is a dilated, twisted superficial vein, 3 mm or more across, felt as a raised line under the skin. If a vein becomes inflamed and clots inside, <b>superficial thrombophlebitis<\/b> appears: a hardened, painful cord with warm, red skin over it. This one should not wait: above the knee it raises the risk of deep vein thrombosis, and an ultrasound scan is advisable. If the leg is also swollen and hard, we set out the causes in <a href=\"\/en\/hard-swollen-leg\/\"><b>hard swollen leg<\/b><\/a>.<\/p>\n\n<h3><b>What are lumps on the legs that come and go?<\/b><\/h3>\n\n<p>A lump that comes and goes is almost never a lipoma, which grows slowly and stays. What appears and disappears is usually inflammatory: a <b>reactive lymph node<\/b>, which settles within a few weeks; <b>erythema nodosum<\/b> nodules, which clear without after-effects; or a <b>hematoma<\/b> after a knock. If it keeps coming back in the same place, or stops going away, it needs to be examined.<\/p>\n\n<p>And a clarification we are often asked for: the dimpled, orange-peel look known as <b>cellulite<\/b> is not a lump, and it is not the same as lipedema. We separate the two in <a href=\"\/en\/difference-lipedema-cellulite\/\"><b>the difference between lipedema and cellulite<\/b><\/a> and in our piece on <a href=\"\/en\/edematous-cellulite\/\"><b>edematous cellulite<\/b><\/a>.<\/p>\n\n<h2><b>Ultrasound: the first test when a lump is unclear<\/b><\/h2>\n\n<p>When touch is not enough, the first test is an <b>ultrasound scan<\/b>. The UK&rsquo;s NICE guideline recommends an urgent ultrasound scan in adults with an unexplained lump that is <b>increasing in size<\/b>, and referral through the suspected cancer pathway if the scan is suggestive, or if it is uncertain and clinical concern persists. The UK sarcoma guidelines place it as the <b>first-line investigation<\/b> and add that, in lower-risk cases, it can confirm benign conditions such as a simple lipoma.<\/p>\n\n<p>Ultrasound tells <b>solid<\/b> from <b>fluid-filled<\/b>: a cyst or a blood vessel is recognized because it has no echoes inside. With Doppler it can also assess varicose veins and other vascular causes. What it does not do is <b>diagnose lipedema<\/b>: the S2k guideline states that the diagnosis of lipedema is <b>clinical<\/b>, because there is no imaging or laboratory test that proves it. Its role is to rule out what imitates it.<\/p>\n\n<p><img loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/lipedemaac.com\/wp-content\/uploads\/2026\/10\/ecografia-partes-blandas-muslo.webp\" alt=\"Ultrasound probe resting on a patient&rsquo;s thigh with the screen of the machine out of focus in the background\" title=\"Soft tissue ultrasound to assess a lump in the leg\" width=\"1600\" height=\"900\" loading=\"lazy\" decoding=\"async\"><\/p>\n\n<h2><b>Where we can check it for you, and where we cannot<\/b><\/h2>\n\n<p>If your lump has any of the warning signs listed at the start, the right place is not a lipedema clinic: it is your <b>GP or family doctor<\/b> and a priority ultrasound scan, wherever you live. We tell you this plainly because it is what is in your interest.<\/p>\n\n<p>If what you notice is dense fatty tissue, tender to pressure and symmetrical in both legs, and you have been told for a long time that \u201cit is just fat\u201d or \u201cit is cellulite\u201d, that is something we do assess. At our clinic in Valencia, the assessment includes an examination of the whole pattern and the differential diagnosis with lipomas, obesity, lymphedema and cellulite.
