This is now corrected and a new case has been added! 

Dear Iskander & Arti. Looks like I was too late to accept your kind invitation! I was a little distracted with the ISDP meeting in Glasgow. Maybe next year. Good luck with the course. Warm regards, Richard

Your still welcome to attend !

 I believe this is melanoma.

To me, melanoma arising in a nevus. 

From Dr Chaudhry:

Thank you I would like to wait for other comments. I would be interested if you both thought the dermal component was benign or malignant - how compelling is the epidermal component towards melanoma in situ? 

In situ melanoma, but I´m concerned about the dermal component. Maybe it represents a desmoplastic melanoma. The lymphocytic inflammation is a clue to this diagnosis.

Melanoma

Severely dysplastic at-least. Not entirely sure about the dermal component on these images. Can't see mitotic figures. Ki67 and p16.

I agree with Nitin, at least dysplastic nevus and I too have not seen any mitoses. But moderate lymphocytic response with areas of fibrosis in the dermis worries me. ?regression

Although dermal component shows smaller cells then junctional ones, I think this is IV level Melanoma, because my impression is there aren’t two different lesions here.  The spindle cells in dermis have spitzoid features and would like knowing about this same case in a teenager.....?????

Difficult one!.... I would probably go for melanoma in situ for the junctional component mainly because the atypia gets diffuse (as opposed to random) and confluent in the 4th image.

Dermal component more tricky. It does appear to mature, but some large cells at the base. Would look carefully for dermal mitoses (including levels) before going for invasive vertical phase melanoma though.

Thanks every one: this case was shown to Dr Alistair Robson and his comments are below:

'It is odd, agreed, but I think this is benign. 

Melanocytic lesions!!....refuse to get easier with time.

A range of diagnosis as usual but have to say Dr Robson's assessment is pretty comprehensive and probably accurate.

Wow we have some very malignant dermatopathologists on this site. My report is brief. Combined dysplastic (Clark) /desmoplastic Spitz (SPARK naevus). A nice combination that makes it stand out clinically and histologically. It needs removing for a blissful nights sleep but surely not a melanoma?
