Melanoma (c28t3P2)

c28t3P1 (case 10): This first illustration is representative of a biopsy specimen. The biopsy was superficial; tumor extends to the deep margin. Fascicles of spindle cells rain down into a widened, edematous papillary dermis. The epidermis is hyperplastic and covered by an inflammatory crust. Some of the nests of cells have migrated upward into the epidermis.

c28t3P2: The lesion recurred approximately one year later. The recurrent tumor was polypoid. In it, fascicles of thin spindle cells are closely aggregated in vertical growth-like patterns. The fascicles of cells extend in the reticular dermis to the deep margin of the field. The lesion is expansile but not encapsulated. Inflammation is not a feature. Lentiginous and junctional patterns are not a feature; the lesion in the recurrence does not have a primary configuration.

GENERAL INDEX

c28t3P3: At its deep margin, the lesion shows an infiltrating pattern of growth. The level is deep level IV. Inflammation is not a feature.

c28t3P4: The pattern is deep level IV growth and also qualifies as migrant vertical growth-like. Inflammation is not a feature.

c28t3P5: The lesion is fairly solid and has an infiltrating quality. Inflammation is not a feature.

c28t3P6: A solid column of tumor cells extend from the main lesion to the deep margin of the field (probably to level V). To the right of the column, thin fascicles of tumor cells infiltrate the reticular dermis among collagen bundles.

c28t3P7: A later recurrence, shows tumor infiltrating a scar; the lesion in this field does not have a primary configuration.
