10.7 POJA-L4354+4358+4356
Title: Basal-cell carcinoma I
Description:
Tumor, stain hematoxylin-eosin, human.
(A): In most cases the tumor (1) arises from the epidermal basal layer and invades the underlying dermis.
Nodular lesions grow downward deeply into the dermis, surrounded by fibroblasts and lymphocytes (especially T-suppressor cells (2).
(3) Melanin-containing cells are present.
(B): Periphery of island of basophilic cells close to the basal cell layer. (3) Yellow-stained melanin in scattered cells is present.
(C): Each island of tumor cells is surrounded by a well-defined columnar layer which forms a peripheral pallisade arrangement of
nuclei (arrows).
Background: Basal-cell carcinoma (basalioma) is a common tumor most frequently in elderly after middle-age on sun-exposed skin.
It starts as a small growing lesion with a depressed center and raised edges. It is a local slow-growing malignant tumor that rarely metastasizes and consists of islands of small dark cells resembling the basal cells of the normal epidermis.
