Melanoma- Skin, right neck, shave biopsy
The Breslow thickness is 0.4 mm, with tissue pathologic staging pT1a
An asymmetrical, poorly circumscribed melanocytic proliferation is present. A confluent arrangement of melanocytes is present along the basal layer in which solitary units predominate over the formation of irregular nests. Foci of haphazard intraepithelial dispersion and adnexal extension are present. Melanocytes are pleomorphic and hyperchromatic. The underlying dermis contains a similar population of atypical melanocytes and in addition, demonstrates a lichenoid lymphohistiocytic inflammatory infiltrate with melanophages. The lesion is highlighted with Sox10 and p16 immunohistochemical staining. Additional deeper sections were obtained and reviewed.
Dysplastic compound nevus with mild architectural and cytologic atypia, tissue edges are involved
There are irregular nests and groups of melanocytes along the base of an acanthotic, lentiginous epidermis. There is frequent bridging between adjacent rate. there is mild fibroplasia and a superficial dermal lymphocytic infiltrate. The dermal infiltrate is central and the junctional component extends beyond the dermal portion. There is minimal to mild atypia of the junctional nests.
I did have the WLE on the melanoma and a bigger biopsy for clean margins on the Dysplastic nevi yesterday. 2 week wait now…again…
Plus I have another black spot like the melanoma that they will removing at my 2 month appt. He wanted to wait and see if it changes any before he removes it. It’s the size of a ballpoint pen tip.
