1800 867 1390Case discussion: How would you treat this patient? [6 June]
In this week’s case discussion, submitted by Dr David Stewart, we look at a 58-year-old male patient with a lesion on his foot that was thought to be from rubbing of his shoes. It has been present for three months.
What do you think, and what would you do?
Update
Here is the pathology result. What next?
– Prof David Wilkinson
We encourage you to participate in the case discussions and submit your own clinical images and questions, so we can all learn together.

Hi One may ask a theme
Hi
Possible scc
Biopsy
Bcc
Excision biopsy
Gray color/dots …white crystalline strictures …….pigmented nevi on periphery……erosion……definitely needs biopsy to rule out melanoma or SCC
Looks like a dermatofibroma, but some atypical features – would do a punch biopsy 3mm to exclude a BCC
Melanoma-ulcerated
Not very clear to comment on though. I can see some subtle branching / polymorphic vessels ? And two ulceration areas. The brownish periphery I don’t know how to comment – is it pigment ?? Anyway would excise to rule out BCC vs AMM.
Peripheral pigmented areas at 12, 3, and 7 o’clock which look like atypical networks with large central white area which could do for regression.
Would consider the lesion as suspicious. Given the poor healing area I would to two punch biopsies. SCC even BCC a possibility.
If the results were negative for skin cancer I would then consider excision biopsy with 2mm margins.
EROSION SURROUNDED BY HYPOPIGMNETED AREA( SCARE)
I THINK TRAUMATIC
Excision biopsy with 2 mm margin
The way the light catches the surrounding skin on the macro picture makes me think there is some tethering going on suggesting something with high cell turnover. I also think the distribution of pigment across the surface of the dorsum is not randomly distributed and may be related to this lesion.
I don’t find the dermoscopy that helpful here, could be anything. I’m inclined to do a good sized punch right in the middle.
BCC
Biopsy
Painless and Non healing for 3 months. Suspicious. Will biopsy and check it out. Not sure of dermatoscope features.
Acc, excision
I would do a shave bx. because it covers a wide are. Excision Bx would not be practical.
SCC? Punch biopsy
An ulcer that persists for 3 months, needs a biopsy clinically. Dermoscopy there is not much to show apart from an ulcer and crystalline white line. Some dotted BVs .The white circles on red could be just actinic sun damage.
IMPRESSION a Basal Cell Carcinoma vs ongoing Trauma vs Bowens ( not many features)
PLAN a biopsy first , then management will be dependent on the histology.
Looking again at the Clinical and Dermoscopic images, the BCC reported with the histology is likely superficial BCC rather than deeper or more aggressive. The size and location is problematic.
PLAN I would follow up after the curette, to allow time for healing. I am not sure whether the base had diathermy treatment. Cryosurgery or imiquimod ( though could be problematic in that area ) could be used to deal with any residual BCC.
It is necessary to remove the lesion as far as possible ( more than $mm margin ) and to take a sample from the bones and surrounding tissue to assess the extension of the lesion and bring all to the pathologist.
5 mm eclipse excision
Appears like a morpehaform BCC, an aggressive subtype, a WLE with 5mm margin can be done and close with a rotation flap.
BCC subtype, depth and any infiltration not established as curettage only not formally biopsied. It is unknown if the cancer is cured or not.
I would do a couple of punch biopies of the area to try and determine this including to determine if there is undeed residual tumour. Any further action other than continued observation would be dictated I think by the histology.
I believe it is a SCC that needs to have an excision biopsy with 2-3mm marginal clearance, viewing for wider excision if required.
use serial 4 weekly cryotherapy- can get excellent results without need for excision
Clearly a lesion that needs a biopsy, despite the history and possible cause from trauma. What biopsy is best? Perhaps, I suggest a shave here, and the shave itself might be enough as a cure as well, noting that the lesion is fairly small
