UNASSIGNED: Neurofibromatosis type 1 is a benign peripheral nerve tumor, often manifests as plexiform neurofibroma that may cause severe dysfunction, pain, and disfigurement. Bleeding has been reported as a complication of plexiform neurofibroma due to vascular fragility and vasculopathy that may develop into life-threatening bleeding especially after excision procedure. Consequently, post excision complications also include dehiscence and infection.
METHODS: We report a 23-year-old male with elephantiasis of the left lower extremity due to giant plexiform neurofibroma who underwent preoperative embolization followed by serial surgical mass reduction. There were postoperative complications consisting of hematoma, wound dehiscence, and infection.
UNASSIGNED: Negative pressure wound therapy is often used to accelerate wound healing, including infected wounds. However, negative pressure wound therapy has been a debatable modality for wound care of neurofibroma due to reported risks of profuse bleeding during its use.
CONCLUSIONS: In this case, despite the size, negative-pressure wound therapy has shown good results for infected neurofibroma wounds and as an adjunct as wound dressing for defect closure of neurofibroma with split-thickness skin graft.

Neurofibromatosis type 1 (NF-1) is the most common neurocutaneous syndrome. Despite its more common appearance relative to other phakomatoses, it has a large variety of disease manifestations that can, at times, make swift diagnosis more challenging if not readily recognized, especially when presenting in an atypical manner. Our case reveals an unusual presentation of NF-1. After initially presenting with a bug bite on the lip with progressive swelling and surrounding inflammatory changes despite treatment with oral antibiotics, a CT scan was performed and demonstrated inflammatory changes surrounding the lip with an adjacent inflammatory mass lesion. Due to hypoattenuating lesions within the retropharyngeal space and misinterpretation by the otorhinolaryngologist, aspiration was attempted but unsuccessful, and the patient\'s condition worsened. Subsequent MRI was able to confirm the presence of numerous neurofibromas. The patient gradually improved on an extended course of antibiotics and was discharged in stable condition. Familiarizing oneself with the more specific imaging characteristics of this relatively common neurocutaneous disorder can help prevent incorrect or delayed diagnosis and ensure proper management. Furthermore, identifying these features on CT scan and MRI can differentiate them from other mimicking pathologies on each modality. Recognition of a scarcely reported infected neurofibroma as an established diagnostic entity could be important to include in the differential of similar cases in the future and subsequently aid in proper diagnosis and management.
