I am so happy that I found an educational gem by Sullivan Nicolaides Pathology , a private pathology lab in Australia. There are some videos of live lectures that one can find here. I am particularly excited (and maybe starstruck) to find Professor David Weedon's lectures here -- as I am particularly fond for Dermatopathology. A particular thing I learned today from Professor David Weedon was a checklist mnemonic for perivascular infiltrate in the skin: 8L's and DRUGS Light reaction Lymphoma (and pseudo) Leprosy Lues Lichen striatus Lupus erythematosus Lipoidica (and incomplete granuloma annulare) Lepidoptera (arthropods etc) Dermatophyte Reticular erthymatous mucinosis Urticaria Gyrate erythema Scleroderma
