Back lesion

A 65-year-old man with many pigmented lesions on his back. One of this lesion was atypical.

Dermoscopy revealed:

• multiple colors
• an atypical reticular network
• regression
• a reticular depigmentation  (rectangle)

Pathology revealed a melanoma in situ.

A 32-year-old man consulted for this enlarging pigmented lesion.

Clinical presentation: multiple couleurs, asymmetry

Dermoscopy revealed:

• multiple colors
• irregular dots
• pink structureless area
• irregular blotch
• regression

This lesion was easily diagnosed superficial spreading melanoma.

Pathology revealed a superficial spreading melanoma with a Breslow index at 0.5mm

A slowly enlarging pigmented lesion

A 32-year-old woman consulted for a pigmented lesion on her left arm. This lesion was slowly enlarging for 3 years.

 Dermoscopy revealed:

• an atypical reticular pattern with a total disorganization
• multiple colors
• signs of regression

 Two punch biopsies were performed.
Pathology was in favor of a melanoma in situ.
Lesion was excised with a 0.5 margin.

Pectoral lesion

A 52-year-old man presented this pectoral lesion. No clinical history was available.

Dermoscopy revealed:

• multiple colours
• a multi-component pattern
• an atypical reticular pattern
• some pseudopods 
• irregular blotches
• regression areas

Pathology confirmed the diagnosis of superficial spreading melanoma.

Pigmented breast lesion

A 28-year-old woman consulted for an enlarging pigmented lesion on her left breast.

Dermoscopy revealed:

• a multi-colored pattern
• a multicomponent pattern
• asymmetry in 2 axes
• an atypical reticular pattern
• some atypical dots/globules
• a scar-like depigmentation
• a blue white veil

Pathology revealed a superficial spreading melanoma with a Breslow index at 0,5mm

Facial lesion

A 55-year-old woman consulted for this pigmented lesion on her forehead.

This lesion was present for 3 years and had progressively changed of colour.

Dermoscopy revealed:

• multiple colours
• an atypical reticular network (white square)
• regression areas: depigmentation and blue grey dots (yellow square)
• irregular blotches (white circle)
• follicular plugs (red arrow)

This lesion was excised and pathology revealed a superficial spreading melanoma with a Breslow Index at 0.24mm.

melanoma

A 82-year-old woman consulted for this dark pigmented lesion on her left arm. Clinically a melanoma was suspected.

Dermoscopy revealed:

• a multi-coloured pattern
• a blue white veil
• blue gray dots
• whitish scar-like depigmentation
• polymorphous vessels including linear irregular vessels

Superficial spreading melanoma

A 66-year-old man consulted for a pigmented lesion on his left scapular area.

Dermoscopy revealed a multi-component pattern, asymmetry, and multiple colours (tan, dark brown, black, blue gray, white).
Other signs were an atypical reticular pattern (irregular holes and thick lines) with a sharp demarcation, a blue-white veil and atypical vessels (irregular linear vessels), a central ulceration (crust). Dots were irregularly distributed.

All these dermoscopic signs were in favor of a superficial spreading melanoma.

Superficial spreading melanoma

A 50-year-old man presented an irregularly pigmented lesion his back. Dermoscopy revealed an asymetric pigmentation, multiple colors, streaks (red circle), and a delicate blue white veil in favor of a superficial spreading melanoma.
The lesion was removed with a 2 mm margin and histology confirmed the diagnosis. The Breslow index was measured 0.63 mm. A re-excision was performed with a 1 cm margin. No mestastases were detected.

Invasive melanoma

A 62-year-old man consulted for this multicolored tumor on his scapular area. This lesion was clinically in favor of an advanced invasive melanoma (nodular melanoma).



Asymmetrical pigmentation pattern, multiple colours , atypical vessels, atypical reticular pattern, blue-white veil, and ulceration were found in this case of invasive melanoma, Breslow thickness 9mm

Superficial spreading melanoma

The clinical aspect of this pigmented lesion was in favor of a superficial spreading melanoma.
Dermoscopy showed multiple colors (tan, dark brown, black, gray, blue), areas of regression (scar-like depigmentation), a blue white veil.
The lesion was excised and pathology revealed a superficial spreading melanoma, Breslow thickness 0.56mm.
