Disease category
Skin neoplasms are a category of diseases characterized by abnormal tissue proliferation in the skin, encompassing various types including skin cancer.
Core mechanism
UV exposure, repeated sunburns, genetic predisposition, immune status, and certain environmental factors can affect the risk of development.
Main causes/related factors
Skin neoplasms occur due to a disruption in the regulation of cell growth and death, leading to abnormal cell proliferation.
Representative features
Typically, newly appearing or changing spots, nodules, or ulcers may appear, and common skin cancers frequently occur on the head, face, neck, hands, and arms.
Individual differences
Those with high sun exposure or a history of sunburn, individuals with light skin, hair, and eye color, those with a family history, and the elderly may have a higher risk.
Diagnosis
The course varies depending on the type and stage; while some lesions remain localized, if left untreated, some skin cancers can spread to other tissues or organs.
Management
Diagnosis involves synthesizing the shape and changes of the lesion, medical history, and skin examination, and suspicious lesions are confirmed with skin biopsy and pathological examination as necessary.
Treatment/Research Status
Observational criteria such as ABCDE help with screening but are not definitive diagnostic criteria, and clinical and pathological interpretation is required to distinguish between benign and malignant lesions.
Read Evidence
Management is carried out by adjusting observation, local treatment, excision, or systemic therapy based on the type, size, location, depth, presence of metastasis, and the patient's overall condition.
Key Precautions
Treatments may include surgery, radiotherapy, chemotherapy, photodynamic therapy, and biological therapy, and treatment is more likely to be effective if detected early.

At a Glance

Skin neoplasms are a category of diseases characterized by abnormal tissue proliferation in the skin, encompassing various types including skin cancer.

Typically, newly appearing or changing spots, nodules, or ulcers may appear, and common skin cancers frequently occur on the head, face, neck, hands, and arms.

How the disease works

UV exposure, repeated sunburns, genetic predisposition, immune status, and certain environmental factors can affect the risk of development.

Skin neoplasms occur due to a disruption in the regulation of cell growth and death, leading to abnormal cell proliferation.

Variations in presentation among individuals

Those with high sun exposure or a history of sunburn, individuals with light skin, hair, and eye color, those with a family history, and the elderly may have a higher risk.

The broad framework of diagnosis and management

The course varies depending on the type and stage; while some lesions remain localized, if left untreated, some skin cancers can spread to other tissues or organs.

Diagnosis involves synthesizing the shape and changes of the lesion, medical history, and skin examination, and suspicious lesions are confirmed with skin biopsy and pathological examination as necessary.

Current status of treatment

Observational criteria such as ABCDE help with screening but are not definitive diagnostic criteria, and clinical and pathological interpretation is required to distinguish between benign and malignant lesions.

Management is carried out by adjusting observation, local treatment, excision, or systemic therapy based on the type, size, location, depth, presence of metastasis, and the patient's overall condition.

Treatments may include surgery, radiotherapy, chemotherapy, photodynamic therapy, and biological therapy, and treatment is more likely to be effective if detected early.

How to read clinical trials

Follow-up is the process of checking for lesion recurrence, new lesions, and post-treatment changes, and the completion status of registered studies alone cannot be used to determine treatment effectiveness or adherence to standard care.

Points to verify during clinical consultations

In clinical practice, it is important to confirm when the lesion began and how it has changed, as well as sun exposure and sunburn history, family history, prior skin cancer and treatment history, immune status, and the need for biopsy.
