Case 1044 24.6.14 (M.Hurt) F 38 pigmented lesion nasal tip (hypopigmented variant)

Wedge-shaped intradermal melanocytic proliferation with spindle and dendritic cells. Variable pleomorphism but no mitoses and no activity on Ki-67 or PPH3. Adnexae not disturbed.

Case 1627 20.9.16 (U. Sundram) F 48 back

Looked like IGD pattern, but too cellular and no mucin. These HBN are S100-ve, Melan-A +ve, in comparison to normal naevi which are, of course, S100 +ve.
