Basal-cell carcinoma II
10.7 POJA-L4357+4355+4360+4361
Title: Basal-cell carcinoma II
Description:
(A): The tumor (1) arises from the epidermal basal layer, note scattered melanin-containing cells, stain hematoxylin-eosin, human.
(B): Tumor nodules grow deeply into the underlying dermis and are surrounded by fibroblasts and lymphocytes (2).
(3) Melanin-containing cells are present.
(C): A few basal-cell carcinomas are aggressive and tend to infiltrate extensively. They grow deeply as small clumps of cells
accompagnied by loosely stroma and show a.o. perineural invasion. (1) Tumor cells. (4) Nerve bundle.
(D): Ramification of perineural tumor invasion (1). (4) Nerve fibres.

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 centre 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.
Keywords/Mesh: skin, basal cell carcinoma, basalioma, histology, pathology, POJA collection
