I would also like to remind you about registering for this College Dermatoscopy and Histopathology Meeting in November. The visiting speaker Dr Clay Cockerell is an excellent lecturer and a leader in the field of skin cancer pathology. This should be a very worthwhile meeting to improve both your dermatoscopy and histopathology skills. We have had 3 cases for the Gems presentations. The Australian Institute of Dermatology is offering one of the following two Dermatopathology Textbooks to each Gems presenter so get in early.
I have put up the histology. This was reported as an in situ Level 1 melanoma which would not be compatible with the colour of this dermatoscopic view. There are obviously melanophages in the dermis and some lymphocytes but do you think there are other cells in the dermis as well and are they benign or malignant on what you are shown? What is causing the blue colour here? I have a video of the slide to put up later and the histology of the other two cases.
ReplyDeleteThe deep blue cells are nevus cells. The pathologists reports these as normal and maturing suggesting that this is an in situ melanoma with a banal dermal nevus component. They may be contributing to the blue colour of the dermatoscopy because of where they are situated. The dermal melanophages should be contributing more grey.
ReplyDeleteCase 2 was a solitary giant molluscum. The lesion on the lateral epicanthus was just a dermal nevus. This was not her histology as I recognised this as a molluscum and just opened the sac and emptied it out. Mind you I confess to excising the previous one she had on her cheek as a presumptive BCC 6 months before! (Always easy the next time!)
ReplyDeleteCase 3 was an SCC in situ pigmented IEC as most people said with the dots in lines. I have put up this histology as well. There is a video there of the actual path slides if you want a better view of the histology of these cases.
