Diagnosis of skin diseases usually involves several steps:

1. Medical history:

• Questions about symptoms, their duration and severity

  •  Medical history and family history
  •  Information about medications, allergies, and other potential risk factors

2. Physical examination:

  •  Examination of the skin, including color, texture, lumps and discharge
  •  Palpation of the skin and subcutaneous structures to detect changes
  •  Examination of the head, nails, mucous membranes and lymph nodes

3. Laboratory tests:

  •  Blood and urine analysis to rule out systemic diseases
  •  Microbiological studies (e.g., smear, biopsy) to identify infectious agents
  •  Biochemical studies to assess liver and kidney function
  •  Immunological studies for the detection of autoimmune diseases

4. Diagnostic procedures:

  •  Skin biopsy: Taking a small piece of skin for microscopic examination for differential diagnosis and determination of the stage of the disease
  •  Dermatoscopy: The use of a magnifying lens to examine the skin in detail, especially moles and other lesions.
  •  Patch test: Application of various allergens to the skin to detect contact dermatitis
  •  Photobiopsy: Using ultraviolet light to detect changes in skin structure and function

5. Visualization:

  •  Radiography, ultrasound, or MRI can be used to visualize underlying skin structures and identify underlying infections or neoplasms.

6. Differential diagnosis:

  •  Comparison of symptoms and signs of a disease with similar conditions
  •  Consideration of possible causes and risk factors
  •  Exclusion of other diseases with similar manifestations

Diagnosis of skin diseases can be a complex process requiring thorough examination, laboratory tests and, if necessary, diagnostic procedures. Making an accurate diagnosis is crucial for prescribing appropriate treatment and preventing complications.
