2. Chvostek sign

3. Lisch nodules

Answer : Lisch nodules

There is hypertrophy of the right lower extremity and an irregular peduncular mass with overlying hyperpigmentation and hypertrichosis involving the right trunk, right buttock, and right leg. Histopathological examination was consistent with a soft-tissue neurofibroma. Lisch nodules were seen on ophthalmologic examination, and neurofibromatosis type 1 was diagnosed.
