Had a shave biopsy last week. Nurse called yesterday and said I had to have an excisional biopsy done soon but not to worry because it's not melanoma. I'm scheduled for the next biopsy on December 4th. I'm just not sure why I have to have another biopsy if it's not melanoma. This is what my path report says:
Diagnosis:
Skin of lateral back, T4, right, shave biopsy:
Melanocytic nevus, compound type with unusual architectural features and
severe cytologic atypia. See microscopic description and comment.
Margins negative for nevus in the plane of the sections examined.
MICROSCOPIC DESCRIPTION:
Histologic sections are that of a shave biopsy of skin to the deep
reticular dermis. Centrally, is a compound melanocytic proliferation. The
majority of the lesion is an epidermal melanocytic proliferation consisting
of enlarged vacuolated melanocytes with variable cytologic atypia forming
irregularly sized and shaped nests and single cells which are unevenly
spaced along the dermal epidermal junction. In the superficial dermis are
smaller melanocytes forming nests with a tendency for smaller nests and
single celled growth with descent. A rare mitotic figure is present in the
superficial dermis. There is an associated mild to moderately dense
superficial lymphomononuclear infiltrate and associated dermal melanocytes.
Immunohistochemical stain for MART 1 performed and interpreted here
highlights the aforementioned features and rare scattered melanocytes
demonstrating upward migration but no well-developed upward migration or
confluent growth is identified. Deeper sections have been reviewed.
Any help interpreting this would be greatly appreciated.
