Giant Congenital Melanocytic Nevus
Please click to enlarge.
Note what signs you see.
I (W. Wertelecki, M.D.) see a darkly melanic nevus – I know that it represents “tardive” “satellite” (late or post-natal in appearance as an additional, perhaps metastatic manifestation) of the giant congenital melanocytic Nevus (GCMN) evident in other regions of this patient’s skin. The GCMN more often referred to erroneous as “bathing trunk nevus”. In essence, this condition is a neuro-cutaneous melanocytosis or dysplasia, hamartomatous in nature – which is in this instance a high cancer risk syndrome (over 1% of patients develop a melanoma).
PERSPECTIVE: for further comments please, see the gallery of images of this patient.
