Squamous cell carcinoma of the skin
小结
定义
Cutaneous SCC is the proliferation of atypical, transformed keratinocytes in the skin with malignant behavior. It ranges from in situ tumors (also known as Bowen disease) to invasive tumors and metastatic disease. Precursor lesions for SCCs are called actinic (or sun-damage) keratosis.[Figure caption and citation for the preceding image starts]: Squamous cell carcinoma on the dorsal hand with evidence of extensive sun damageFrom the private collection of Dr Nwaneshiudu and Dr Soltani [Citation ends].
The management of metastatic disease is beyond the scope of the topic.
