Write answer in between .Q:A 13-year-old boy presents with several light brown macules measuring 45 cm located on his trunk. He has no other medical conditions, but his mother has similar skin findings. He takes no medications, and his vital signs are within normal limits. Ophthalmic examination findings are shown in the image below. What is the most likely neoplasm that can develop in this child?? A: Acoustic neuroma, B: Meningioma, C: Dermatofibroma, D: Neurofibroma, E: Retinoblastoma,  <response>: This is a clinical case about a 13-year-old boy with light brown macules on his trunk, similar findings in his mother, and ophthalmic exam findings as shown. The key findings are the skin lesions, family history, and eye exam. The skin findings of light brown macules are consistent with cafe-au-lait spots, which are a classic finding in neurofibromatosis type 1 NF1. The family history of similar lesions also supports NF1. The ophthalmic exam shows Lisch nodules, which are hamartomas of the iris that are pathognomonic for NF1. Neurofibromas are benign peripheral nerve sheath tumors that commonly develop in patients with NF1. Therefore, the most likely neoplasm that can develop in this patient is a neurofibroma. The other answer choices are unrelated to the clinical findings.D: Neurofibroma
