Which characteristic is typical of squamous cell carcinoma (SCC)?

• A. Rapidly growing tumor
• B. Small flat plaque or persistent ulcer
• C. Colorful raised lesions
• D. Consistently painful nodes

Answer: (B)

A small flat plaque or persistent ulcer is indeed a classic presentation of squamous cell carcinoma (SCC). This type of skin cancer commonly arises in areas of sun-damaged skin and is typically characterized by its appearance as a firm, red nodule or a flat sore that bleeds and crusts over. SCC can also present as scaly, rough patches, and while it may not be painful at first, lesions can develop into non-healing ulcers over time. The presence of a small flat plaque or persistent ulcer indicates the often subtly changing nature of SCC, where the lesion may not initially be aggressive but can become invasive. By identifying these characteristics, clinicians can better assess skin lesions for potential malignancy. In contrast, rapidly growing tumors and colorful raised lesions are generally more indicative of other types of skin cancers or dermatological conditions. Similarly, consistently painful nodes are not a hallmark feature of SCC, as lymphadenopathy can occur in various cancer types, but it is not specific to SCC.
