Summary
A case of naevoid lentigo maligna melanoma was identified on a man's nose. Asymmetrical dots, some grey, on dermatoscopy aided in diagnosing this early-stage melanoma.
Area of Science:
- Dermatology
- Oncology
Background:
- Naevoid lentigo maligna is an early-stage melanoma.
- Early detection of melanoma is crucial for patient outcomes.
Observation:
- A 46-year-old man with a history of two melanomas developed a new nasal lesion.
- The lesion measured 1.6 mm and exhibited asymmetrical dots on dermatoscopy.
Findings:
- The presence of grey dots among asymmetrical dots on dermatoscopy was a key diagnostic clue.
- This finding suggests naevoid lentigo maligna (WHO level 1 melanoma).
Implications:
- Dermatoscopic evaluation, including the presence of grey dots, can aid in diagnosing early-stage melanoma.
- This case highlights the importance of surveillance in high-risk patients.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
