a neck lesion?

A 19 years old man came to us with a lesion on his neck that started since he was 4 yrs old (or ealier he s not sure) , the lesion stabilised . its asymptomatic and theres nt a simillar lesion elswhere.

on examination he had a brownish well defined patch covering the left side of his neck. the patch doesnt seem to be hairy but there an obvious swelling underneath and the uninvoloved cheacks are bigger than the other side.

we are waiting for the biopsy results but we thinking of either a beckers nevus or a congenital melanocytic nevus.

is it poiible to have a beckers with this sweeling or are we dealing with somehting else?

ur thoutghs are appreciated!

  1. from the look of it i think its more like combined lesion , us CT or MRI may help see what lies beneath

  2. poor guy! he had it on the worst site possible. i think pigment laser may be helpful here but i would go with low fluences because the neck area to prone scarring.
    i wonder what the biopsy result came to be but am with beckers.
    have you sent for x-rays beckers can be associted with skeletal abnormalties.

  3. biopsy came as:acanothsis regular elongation of the rete ridges and hyperpgimentaion of the basal layer. the upper dermis shows mild lymohcytic infiltrate and deep dermis shows irregular smooth muscle.
    we are treating him as a case of beckers, we sent him for xrays and we gonna start him on alex pigment laser soon.

  4. Yes , this is beckers nevus, especially the finding histopathologically of smmoth muscles (which are the arrector pilorum muscles that usually get hypetrophied with time), so, the color would improve but the thicness would not.I dont think the description irregular for the smooth muscle histopathologically ia apprpriate.Beckes Nevus in fact is a smooth muscle hamartoma.
