[Malignant skin tumours in a private dermatology practice. A quality control study]

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Growing campaigns for early malignant melanoma detection influence dermatological practice.
• Increased prevalence of photodamaged skin necessitates robust diagnostic protocols.
• The study investigates the potential for quality control implementation in private dermatology.

Purpose of the Study:

• To evaluate the diagnostic accuracy of dermatologists in identifying skin tumors.
• To assess the concordance between clinical and histopathological diagnoses.
• To determine the role of private dermatology practices in skin cancer prophylaxis.

Main Methods:

• Prospective registration of all patient diagnoses over one year.
• Comparison of clinical diagnosis with final histopathological diagnosis for surgically removed skin tumors.
• Analysis of diagnostic accuracy for various skin tumor types, including malignant and precursor lesions.

Main Results:

• Of 291 removed tumors, 49% were malignant (including basal cell carcinoma, squamous cell carcinoma, and melanoma).
• Clinical diagnosis agreed with histopathological findings in 71.8% of cases.
• No cancers were detected in clinically benign tumors; however, 48% of atypical melanocytic nevi showed dysplasia.

Conclusions:

• Dermatologists provide high-quality diagnosis and prophylaxis for malignant skin tumors.
• Dermatologists are competent partners for patients and health insurance, offering an optimal cost-performance ratio.
• The findings support the integration of quality control measures within private dermatology practices.
