Solar Keratosis: Chronological Sequence

Fig. 89-7

Squamous cell carcinomas at stages of evolution from keratotic macules of solar keratosis to keratotic papules.


Fig. 89-8 A

Scaly lesions represent superficial squamous cell carcinomas (solar keratoses), whereas eroded lesions are deeper squamous cell carcinomas (solar keratotic type).


Fig. 89-8 B

Scaly lesions represent superficial squamous cell carcinomas (solar keratoses), whereas eroded lesions are deeper squamous cell carcinomas (solar keratotic type).


Fig. 89-9

Spectrum of lesions of squamous cell carcinoma from keratotic macules of solar keratosis to keratotic plaques.


Fig. 89-10

A keratotic plaque is a thick squamous cell carcinoma, and keratotic papules (solar keratoses) are thin carcinomas.
