BOF:21
A 35-year-old male is seen in the follow up clinic. He has
an inherited condition for which he attends an yearly follow up.
On examination, he has 8 café-au-lait macules of over 15 mm
in greatest diameter on his trunk, he has multiple discrete skin nodules
distributed over his trunk and limbs and there is freckling in the axillae.
The patient is worried about his child; a boy of 6. He was
told that examination of the child could conclusively exclude inheritance of
this condition in the child but he has forgotten what the exclusion criteria
were. He asks you to reiterate them and your reply is that this condition may be
confidently excluded if:
a)
The child does not have any café-au-lait macules
b)
If the child has fewer than 6 café-au-lait spots
c)
If the child has no axillary freckling
d)
If the child has no skin nodules
e)
If no member of the mother’s family have been affected
