The following case is a Solitary neurofibroma arising from the right-side obturator nerve, which was impressed as a right-side ovarian Tumor initially [1]. To our knowledge, this is a rare case of a solitary neurofibroma arising from the obturator nerve [2]. We present a rare, difficult to diagnose and may-be the seventh Pediatric case of solitary neurofibroma of the cauda equine in an 11-month-old Infant [3]. The patient consequently received a Roux-en-Y hepaticojejunostomy and was confirmed with neurofibroma pathologically [4]. They occur rarely in the gastro-intestinal tract as isolated neoplasms, outside the classical clinical feature of neurofibromatosis [5].

We herein present an isolated colonic neurofibroma without any Systemic signs of neurofibromatosis [6]. This case report describes an unusual presentation of solitary neurofibroma on the lingual gingiva of the mandibular posterior region of a 22-year-old Woman [7]. Based on the histopathologic findings, a final diagnosis of neurofibroma was made [8]. The patient underwent left subtotal Temporal bone resection, and histological and immunohistochemical findings confirmed the lesion to be a neurofibroma [9]. Treatment of Localized and Diffuse neurofibromas is often surgical resection, which may require sacrifice of the nerve [10].

Solitary neurofibromas of the male genital tract are exceedingly rare Benign peripheral nerve sheath neoplasms composed of Schwann Cells and fibroblasts [11]. Histopathology report identified the Mass consistent with neurofibroma [12]. He exhibited no skin Pigmentation, no hearing deficit, and no evidence suggestive of any Systemic disorders that might have been attributable to the Tongue base neurofibroma [13]. Thus, a diagnosis of isolated neurofibroma of the Tongue was established [14]. We report a case of a 55-year-old Female with no history of neurofibromatosis who presented with a slow-growing, Painless lump on her torso [15].

She was diagnosed with solitary Subcutaneous neurofibroma with features of Malignant peripheral nerve sheath Tumor transformation [16]. Although mostly associated with neurofibromatosis, it can be Solitary [17]. solitary neurofibroma may occur in deep soft tissue or Subcutaneous plane in rare cases associated with syndromes like NF1 [18]. The neurofibroma most commonly present as skin lesions as isolated soft Papules or Nodules arising in any cutaneous site [19]. They can be Solitary or may be associated with neurofibromatosis type-1 (NF-1) [20].

This work also discusses the various differential diagnoses that can be considered in similar cases [21]. Other Benign tumours included inverted papilloma, squamous papillomas and extrapleural solitary neurofibroma Tumor [22]. Neurofibromas are usually found in individuals with neurofibromatosis, which is an Autosomal dominant disease [23]. Although solitary neurofibroma that occurs in the paranasal sinus is reported occasionally, neurofibroma located in the frontal sinus is extremely rare [24]. Here, we report a case of a young Woman who had a heterogeneous Lesion in the left frontal sinus, eroding its anterior and posterior wall with signs of intracranial invasion [25].

Postoperatively, results of the histologic examination confirmed the diagnosis of solitary neurofibroma [26]. We also report a case of a solitary neurofibroma of the gingiva in a 72-year-old male of 15 years duration [27]. Generally, a solitary neurofibroma is located in the skin and rarely in other places [28]. Histological examination revealed gastric adenocarcinoma, invading the Mucosa without nodal Metastasis, and a neurofibroma [29]. Clinical, radiographic, magnetic resonance imaging (MRI), and histopathologic features are presented, as well as, a review of the literature [30].

We present a case of frontal sinus neurofibroma treated successfully with Surgical Excision [31]. Histopathological examination showed the Tumor to be a neurofibroma [32]. We studied the effect of this modality on a giant solitary neurofibroma of the Neck [33]. Three months post-PDT, MRI revealed a significant reduction in the neurofibroma size [34]. Solitary Subungual neurofibroma appears to be a rare condition [35].

Up until now, less than 10 case reports of Solitary Subungual neurofibroma have been documented [36]. Solitary Subungual neurofibroma is difficult to diagnose, particularly as it is often small and without obvious symptoms [37].
