Tracking Identifier (0062,0020) is used to store the skin lesion label.

Tracking Unique Identifier (0062,0021) is used to store a vendor generated skin lesion UID.

Lesion identifier label is auto-generated by the image display / evidence creator actor.

Measurements in the lesion tracking reporting windows are auto-populated from measurement tools in the image display / evidence creator actor.

Procedure reported is auto-populated e.g., (121058, DCM, "Procedure reported") = (446078004, SCT, "Dermoscopic photograph").

There is potential to use the DICOM Structured Report Template Section TID 1500 Measurement Report for skin lesion tracking.

The DICOM Structured Report object would contain the SOP Instance UID of the dermoscopic image as it is unlikely a segmentation object would be required given that dermoscopy field of view is a single lesion.
