Read this article to learn more about:

• identifying some mutual skin lesions that you lot might run across in full general do
• managing pare lesions after a diagnosis
• when an urgent referral for suspected skin cancer may exist required.

Skin lesions are a frequent presentation in general practice so it is important for clinicians to be able to distinguish benign weather from those such as melanoma that will crave urgent referral and treatment. The majority of skin lesions referred urgently via 2-calendar week wait referrals for suspected peel cancer are constitute non to be malignant, indicating that there is a need for ameliorate recognition of not-cancerous peel lesions in primary intendance.¹

A thorough history and examination will help with diagnosing skin atmospheric condition and guide the next steps for referral and management. Ask the patient almost how long the lesion has been present, if information technology has grown and/or changed in shape, if in that location is any associated pain, and if information technology bleeds or oozes. Any by medical history or family history of skin cancer should exist identified.²

A systematic examination of the lesion based on the history will help with diagnosis and ensure that serious conditions such as melanoma can be ruled out. If the diagnosis is uncertain, specially if symptoms are non typical, then the clinician may desire to talk over the signs and symptoms with a specialist to decide whether a referral is required.³

Red flags

Around thirteen,000 melanomas are diagnosed every year in the UK, which ways the boilerplate GP is probable to encounter a melanoma one time every 3 to v years. NICE recommends referring patients urgently via a 2-calendar week suspected cancer pathway for melanoma if a suspicious pigmented skin lesion scores 3 or more than using the weighted seven-point checklist (see Box one).³

Box 1: Weighted 7-bespeak checklist for melanoma^three

• Major features of the skin lesions (scoring 2 points each):
  • change in size
  • irregular shape
  • irregular colour
• Small features of the peel lesions (scoring 1 bespeak each):
  • largest diameter ≥7 mm
  • inflammation
  • oozing
  • change in sensation.

The following case studies aim to illustrate the classic features of some common skin lesions and how to manage and refer as appropriate.

Case 1

A 68-year-one-time man presents with a small lesion on his right cheek, which he says has been at that place for several weeks. Information technology is a firm lesion which is dry, crimson, and does not bleed.

Diagnosis

The diagnosis is basal cell carcinoma (BCC) (come across Figure 1). BCCs are the most common course of skin cancer, accounting for around 80% of all skin cancers. People with white skin have a lifetime risk of 20–40% of having a BCC.^iv Effectually 75,000 BCCs are diagnosed every yr in the UK, which means the average GP is likely to diagnose one BCC per year. BCCs are very rarely fatal only early diagnosis is important to avert extensive and potentially disfiguring handling.³

Known hazard factors for BCC include exposure to ultraviolet light, increasing historic period, having fair skin that burns easily, immunosuppression, smoking, trauma, previous BCCs, and Gorlin syndrome. Sunday-exposed areas, particularly on the caput and neck, are most commonly affected but BCCs tin can occur on any office of the body. Patients may have more than one BCC then it is important to examine their peel thoroughly.^{4 , 5}

BCCs are often slow growing, vary in size and appearance, and may exhibit spontaneous haemorrhage, scabbing, or ulceration. They are not normally painful. They may exist skin-coloured, pink, or pigmented, but the appearance will vary according to the blazon of BCC (Table ane). While it might be possible to diagnose a BCC visually, excision biopsy is often used to confirm the diagnosis.^{ane ,3–5}

Table 1: Dissimilar types of BCC¹

	Common location	Features
Nodular	Face	Cystic, pearly, telangiectasia May be ulcerated Micronodular and microcystic types may infiltrate deeply
Superficial	Upper torso and shoulders Often multiple	Erythematous well-demarcated scaly plaques, often >xx mm Boring growth over months or years May be confused with Bowen'due south disease or inflammatory dermatoses
Morphoeic (or sclerosing or infiltrative)	Mid-facial sites	Skin-coloured, waxy, scar-like Prone to recurrence later treatment May infiltrate cutaneous nerves
Pigmented		Brown, blue or greyish lesion Nodular or superficial histology May resemble cancerous melanoma
Basosquamous		Mixed BCC and squamous cell carcinoma Potentially more aggressive than other forms of BCC

BCC=basal cell carcinoma

Management

NICE recommends routine referral for peel lesions suspected to be BCCs; however, if the clinician is concerned about factors such every bit lesion site or size relating to a suspected BCC, then an urgent 2-week cancer referral may be appropriate.ⁱⁱⁱ The Principal Intendance Dermatology Guild recommends that basosquamous BCCs should as well exist referred urgently.^four

Nearly BCCs will exist removed using superficial skin surgery or cryotherapy, with other methods including photodynamic therapy and radiotherapy. However, superficial BCCs can often be managed medically without the need for surgery.^one

Clinical outcome

The patient's BCC was surgically removed via excision and primary closure. Histology confirmed a 'nodular basal cell carcinoma reaching the reticular dermis'.

Example two

An eighty-twelvemonth-old woman presents with a lump on her right shoulder, which she has had for approximately two weeks. She describes it increasing in size. She has always lived in the UK and describes her peel as 'called-for easily' on exposure to the sunday.

Diagnosis

The diagnosis is squamous cell carcinoma (SCC)—the second most common form of peel cancer (see Figure 2). Effectually 25,000 SCCs are diagnosed every yr in the United kingdom, which means the average GP is probable to diagnose one every 1 or 2 years.ⁱⁱⁱ

SCCs share many chance factors with BCCs, with the addition that patients who take had a transplant and are taking immunosuppressants are more decumbent to developing SCCs and these lesions can be aggressive. The backs of hands, forearms, upper face, lower lip, and the ear are mutual sites and they tin also be found in areas of chronic inflammation, such as leg ulcers. SCCs occur most oftentimes in older patients only they may exist found in younger patients who accept xeroderma pigmentosum, albinism, or epidermolysis bullosa.^vi

SCCs grow more rapidly than BCCs and tend to exist painful or be associated with sensory changes. A characteristic sign of SCCs is induration and the tissue around the lesion may appear inflamed. As with BCCs, the diagnosis will normally be confirmed with excision biopsy.^{3, 6}

Management

NICE recommends that suspected SCCs should exist referred via the ii-week suspected cancer pathway.³

Although almost SCCs tin can be treated successfully, they can occasionally metastasise.^{half dozen} Larger and deeper SCCs are more than likely to metastasise, as are poorly differentiated tumours.^vii

Cutaneous SCCs are nearly always managed by surgical excision, including Mohs micrographic surgery if possible, which is associated with a lower local recurrence rate than other treatments. SCCs will be excised with a margin of effectually four–10 mm depending on the size of the lesion to ensure that the whole tumour is removed. Skin grafts or flaps may be needed to repair the defect. Alternative methods of removal include curettage and electrocautery, cryotherapy, and radiation therapy.^vii

About SCCs are cured by treatment. Nearly 50% of patients at high risk of SCC develop a 2d one within five years of their first lesion. They are as well at increased risk of other skin cancers, especially melanomas.⁸

It is worth noting the importance of educating the patient regarding regular cocky-peel examinations, and longer annual pare checks.^eight

Clinical outcome

The patient had her lesion examined with a dermatoscope and features were constitute to be consequent with an SCC. This patient'south lesion was removed via minor surgery with iv mm margins. Histology confirmed a keratoacanthoma-like well differentiated phase pT1 SCC.

Case three

A 34-year-old woman presents with a four mm lesion on her left thigh that has been present for several months. It is firm, solid, and painless. She does non believe it has increased in size.

Diagnosis

The diagnosis is dermatofibroma (see Figure 3). Dermatofibromas are common benign fibrous nodules that frequently occur on the thighs and lower legs. They are more common in females and in young adults.⁹

People may have i or multiple lesions. They vary in size but most are around v mm and slightly elevated, though they can be larger. They occur as firm nodules that dimple in the middle when the pare is pinched. They are often red or light brown and are ordinarily asymptomatic but they can exist painful if knocked.⁹

Management

Dermatofibromas do non unremarkably crave treatment; however, they are occasionally removed when the diagnosis is uncertain or if causing undue discomfort. Treatment is by surgical excision, with all specimens sent for histology.⁹

Clinical consequence

The patient was told by her GP after clinical test that this peel lesion was a dermatofibroma. She was given a patient information leaflet virtually the condition and was reassured and told to come back if the lesion changed in shape or color.

Example 4

A 75-year-quondam human comes back for a check upwards for a large, night brown mole on his back that has grown bigger over the final 12 months. He said he wouldn't have come to the surgery but his wife was concerned.

Diagnosis

The diagnosis is seborrhoeic keratosis(encounter Figure 4). Seborrhoeic keratoses are mutual benign lesions that nowadays as people get older. They are often found on the torso and face and can occur in big numbers. They are usually brown or blackness, though can be paler, and therefore when highly pigmented may resemble cancerous lesions.¹⁰

They ofttimes look equally if they are greasy and have a 'stuck-on' appearance. They are typically one–3 cm in diameter, although they tin be larger. Sometimes they showroom the Leser-Trélat sign, which is the sudden occurrence of multiple seborrhoeic keratoses.^ten

Management

Most seborrhoeic keratoses do not demand whatsoever treatment. Notwithstanding, if at that place is any doubt virtually diagnosis, it is recommended to refer nether the ii-calendar week rule. If removal is desired, then the management options are cryotherapy, curettage, and cautery, with samples sent for histology.¹⁰

Treatment outcome

After clinical exam by his GP, the patient was told that the lesion was a seborrhoeic keratosis. He was reassured and was told to come back if the lesion changed in shape or colour.

Conclusion

Peel lesions are a common presentation in master care, many of which can be diagnosed based on history and clinical exam. The challenge for GPs is in distinguishing between benign and malignant lesions, so that only those that require urgent review and treatment are referred under the ii-week expect.
