Early squamous cell carcinoma (SCC) typically presents as a firm, persistent growth or patch on skin that has been damaged by years of sun exposure. Because these areas—particularly the ears and the backs of the hands—receive significant ultraviolet (UV) radiation, they are among the most common sites for this type of skin cancer. Unlike many other skin conditions, an early SCC is often felt before it is clearly seen, often appearing as a rough or thickened area that does not resolve with standard moisturisers.
The National Health Service explains that squamous cell carcinoma often appears as a firm pink lump with a rough or crusted surface, frequently occurring on the face, ears, and hands. Identifying these changes at an early stage is vital, as SCC has the potential to grow more quickly than other common skin cancers and requires prompt clinical intervention.

The primary physical traits of early SCC
In its early stages, a squamous cell carcinoma often looks like a firm, pink or red lump (nodule) or a persistent, scaly patch. One of the most defining characteristics is the texture; the surface is usually rough, crusted, or hyperkeratotic, meaning it has a build-up of the protein keratin. This can sometimes lead to the formation of a cutaneous horn, which is a hard, spiky outgrowth of keratin that looks like a small horn or spike sticking out from the skin.
On the ears and hands, these lesions may start as a small, non-healing sore or a thickened area of skin that feels like sandpaper. Clinical guidelines from the Primary Care Dermatology Society note that SCC typically feels firm to the touch (indurated) and may have a red, inflamed base. Unlike a simple wart or a dry skin patch, an early SCC will steadily increase in size over weeks or months and may become tender when pressed.
Distinguishing SCC from actinic keratosis
It can be difficult to tell the difference between an early SCC, and a pre-cancerous condition called actinic keratosis (AK). Both conditions appear on sun-damaged skin and present as rough, scaly patches. However, actinic keratoses are generally thinner and more superficial. An early SCC is distinguished by its thickness and the presence of a firm lump beneath the scale.
A key clinical indicator of transformation into SCC is when a previously flat, scaly patch starts to thicken, grow rapidly, or become painful. While many actinic keratoses are harmless and may even regress, any lesion that begins to feel like a distinct lump or develops a raised, heaped-up edge is a cause for concern. Because SCC on the ear is considered a higher-risk site due to its potential for deeper invasion, any scaly growth in this area should be reviewed by a professional with a high degree of suspicion.
Specific signs on the ears and hands
On the ear, an early SCC often appears on the pinna (the outer rim), which is the most sun-exposed part. It may look like a small, crusty ulcer or a firm, flesh-coloured bump that occasionally bleeds. Because the skin on the ear is thin and sits close to the cartilage, even a small lesion can feel quite firm and fixed. On the hands, SCC typically develops on the dorsal surface (the back of the hand), appearing as a thickened, wart-like growth or a persistent scaly patch that catches on clothing.
NICE clinical guidelines recommend an urgent referral for suspected SCC if a lesion is growing rapidly or shows signs of ulceration and induration. On the hands, SCC is often associated with other signs of sun damage, such as blotchy pigmentation and thinning of the skin. If a spot on your hand or ear develops a central crust that repeatedly falls off and reforms, or if it feels tender when touched, it is essential to have it assessed by your General Practitioner.
The importance of rapid growth and tenderness
Unlike basal cell carcinoma, which grows very slowly over many months or years, a squamous cell carcinoma can show visible changes over just a few weeks. This rapid growth is a major clinical warning sign. Patients often report that the lesion has become noticeably larger or thicker in a short period. Another important symptom is tenderness; while many early skin cancers are painless, SCC is frequently sensitive to pressure or touch.
If a lesion starts to bleed spontaneously or develops into an open sore that does not heal within four weeks, it is a significant indicator of malignancy. In advanced or neglected cases, the centre of the lump may break down into a raw ulcer with a purulent (pus-like) or crusty surface. Because of the risk of the cancer spreading to local lymph nodes, identifying these symptoms of rapid evolution and persistent inflammation is the primary goal of early detection.
Conclusion
Early squamous cell carcinoma on the ears or hands typically presents as a firm, thickened, and scaly growth that may be tender or prone to bleeding. It is often distinguished from pre-cancerous actinic keratosis by its thickness and rapid progression over weeks rather than months. Because the ears and hands are high-risk areas, any persistent, growing, or painful skin abnormality should be examined by a healthcare professional promptly.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is a skin horn always cancerous?
No, a cutaneous horn is a build-up of keratin that can sit on top of benign, pre-cancerous, or cancerous lesions, but it must be biopsied to rule out an underlying SCC.
Does early SCC itch?
While it is more commonly tender or painful, some patients do report an itching or stinging sensation in the area as the lesion grows.
Can SCC look like a wart?
Yes, some subtypes of SCC are verrucous, meaning they have a wart-like texture, which is why any new wart in an older adult should be checked.
How fast does SCC grow?
SCC typically grows much faster than other non-melanoma skin cancers, often showing significant enlargement over a period of four to eight weeks.
Why is the ear a high-risk site?
The thin skin on the ear allows the cancer to reach deeper structures like cartilage more easily, and it has a slightly higher risk of spreading to local lymph nodes.
Is SCC curable?
Yes, the vast majority of squamous cell carcinomas are completely cured with simple surgical treatment if they are identified and treated early.
What should I do if my GP is not sure?
If there is doubt, your GP should refer you to a dermatologist for a more detailed examination, often using a dermatoscope.
