I had a punch biopsy done on [part of my mole] on my face. The mole itself is about the size of a pencil eraser. The punch biopsy was 0.3 cmx0.3 cmx0.3 cm, which took out all of the "dark" part of the mole. It's the healthy [looking] part of the mole that remains. I'm not understanding all of the scientific description below. I understand in situ to be a low risk lesion to likely not spread- is that correct? How often does in situ's ...upstage after my wide local re-excision? Anyone know how big the scar is going to be?
Diagnosis: Punch Biopsy: Melanoma in Situ (face, cheek).
Recommendation: Wide local re-excision (5mm margin) scheduled next week.
- punch biopsy shows presence of an atypical junctional melanocytic lesion characterized by occasional nests of atypical melanocytes along the base of the epidermis with the long axis parallel to hte epidermal surface as well as single melanocytes with atypical cytological features extending into the upper portions of the epidermis as well as focally showing a confluent growth patter along the basal layer.
There is involvement of follicular epithelium. There are melanophages in the superficial dermis as well as mild perivascular chronic inflammation. There is absence of an intradermal melanocytic omponent in the punch biopsy. There is minimal dermal solar elastosis. The lesion extends to and is present in the peripheral borders of the punch biopsy. The specimen is 0.3cm x 0.3 cmx 0.3 cm in depth.
