What are the Histological Features of Malignant Lesions?
Malignant lesions exhibit certain key histological features such as cellular atypia, increased mitotic figures, and invasion into surrounding tissues. Basal cell carcinoma shows nests of basaloid cells with peripheral palisading nuclei. Squamous cell carcinoma is characterized by keratinocyte atypia and keratin pearl formation. Melanoma, one of the most aggressive forms, is identified by atypical melanocytes invading the dermis. Recognizing these features is essential for the effective management of skin cancers.
