    Journal: Andes Pediatr; 2022 Oct; 93(5):741-748. PubMed ID: 37906895.
    Abstract:
    UNLABELLED: Neurofibromatosis type 1 (NF1) is the most frequent genodermatosis. Its cutaneous findings are key for early diagnosis, as they usually appear at early age. Café-au-lait macules are the most known cutaneous findings. Neurofibromas are the most frequent cutaneous tumors in patients with NF1, showing multiple clinical manifestations. They are classified as superficial and deep lesions, and su perficial neurofibromas are subdivided in cutaneous or subcutaneous. Some neurofibromas may be present since birth; however, most appear during adolescence. Neurofibromas constitute 2 out of 7 of the NIH criteria of Neurofibromatosis type 1. Most of them are benign, do not require treatment and their recognition allows an early diagnosis of the disease. OBJECTIVE: To describe and classify neu rofibromas associated with NF1 through a clinical case. CLINICAL CASE: 18-year-old male diagnosed since childhood with NF1 presents with multiple oval nodules on his face, occipital area, and wrist, multiple blue-red macules on his back and an asymptomatic pink plaque in his thigh. Ultrasound of the nodules was suggestive of neurofibromas and a skin biopsy of the lesions in the back and thigh were consistent with cutaneous neurofibromas. CONCLUSION: This case illustrates the varied clinical manifestations of neurofibromas in adolescence. Recognition of neurofibromas by the pediatrician, pediatric neurologist and/or dermatologist is crucial for the early diagnosis of NF1.
