Non-melanocytic lesions Part 2

The Non-Melanocytic Lesions Part 2 course provides in-depth knowledge and practical tools for the identification, diagnosis, and management of malignant non-melanocytic lesions. This comprehensive unit emphasises dermoscopic evaluation, histological correlation, and evidence-based approaches.

This course explores the clinical, dermoscopic, and histological features of key malignant non-melanocytic skin lesions, including squamous cell carcinoma, basal cell carcinoma, and keratoacanthoma.
Key topics include:
- Squamous Cell Carcinoma (SCC)
- Differentiating SCC in situ (Bowen’s disease) from invasive SCC.
- Dermoscopic features of SCC, such as white circles, surface keratin, and polymorphic vessels.
- Diagnostic challenges in collision lesions and distinguishing SCC from actinic keratosis.
- Histological characteristics, including atypical keratinocytes, parakeratosis, and mitotic figures.
- Keratoacanthoma
- Recognising the architectural and cytological features of keratoacanthomas, including their symmetrical structure and central keratin-filled crater.
- Understanding their benign behaviour and management options.
- Basal Cell Carcinoma (BCC)
- Overview of BCC subtypes: nodular, pigmented, superficial, and aggressive forms such as infiltrative and morpheaform.
- Dermoscopic patterns, including fine arborizing vessels, translucent stroma, and clefting at the stromal-tumor interface.
- The importance of early detection and intervention for deep or aggressive BCC.
- Other Malignant Lesions
- Introduction to less common malignancies, such as Merkel cell carcinoma and cutaneous lymphoma.
- Dermoscopic and histopathological features for differential diagnosis.
- Practical Applications and Case Discussions
- Interactive case studies to reinforce learning and application of diagnostic algorithms.
- Evidence-based approaches to treatment and follow-up care.

By completing this course, participants will gain the expertise to accurately diagnose and manage malignant non-melanocytic lesions, reducing morbidity and improving patient outcomes. This program is essential for clinicians seeking advanced skills in dermoscopy and dermatopathology.

1. Apply clinical and dermatoscopic information in evidence-based decision making with respect to skin lesions
2. Define and use key terminology for dermatoscopy
3. Apply decision algorithms in the diagnosis of both pigmented and non-pigmented skin lesions
4. Define and use terminology used in dermatopathology
5. Distinguish the histological features of common and less common benign and malignant non-melanocytic skin lesions
