Case 3

7 years old Indian girl has such hyperpigmented rash over the right thigh since birth. It has increased in size over the years. For the last three months, she complained of tender on touching the lesion. On palpation, there were multiple subcutaneous nodules felt, which were tender. In addition, she has mulitple (>10) cafe-au-lait spots over her back.

Other significant history was, her father also has numerous cafe-au-lait spots, as well as numerous neurofibromata and axillary freckling; clinically consistent with Neurofibromatosis type1.

Diagnosis?
I am not too sure about it.
My boss said it is congenital hairy nevomelanocytic nevus, probably not related to NF1.
