Intrascrotal solitary neurofibroma: A case report and review of the literature

A Giant Scrotal Neurofibroma in a Child Masquerading as Filariasis: Uncommon Presentation of a Common Disease

Neurofibroma of the scrotum is a very uncommon benign neoplasm, specifically when it affects teenagers and is not associated with neurofibromatosis type I. To the best of our knowledge, only a couple of cases of neurofibroma in children have been documented. Here, we report a case study of a 17-year-old boy who had a giant scrotal lump for ten years masquerading clinically as filariasis. A provisional diagnosis of benign nerve sheath neoplasm was made based on cytology findings. The lump was surgically removed from the patient, and a histopathological and immunohistochemistry examination established the diagnosis of neurofibroma. The combined clinical, preoperative cytological, histological, and immunohistochemistry findings were not presented in the literature in any of the formerly documented cases of scrotal neurofibroma. The current case expands the spectrum of differential diagnoses for scrotal tumours that clinicians have previously observed.

Diagnosis and Management of Intrascrotal Nerve Tumors: A Systematic Review of the Literature

Scrotal tumors of nerve origin are extremely rare and occur mostly in the extratesticular tissues of scrotum, such as the spermatic cord and epididymis. A systematic search of the literature in PubMed, Medline, and Google Scholar databases concerning intrascrotal nerve tumors was performed by 2 independent investigators. The systematic search retrieved 45 male adults, with a mean age of included patients at 43.9 ± 18.8 years. The majority of nerve tumors were extra-testicular (86.7%), and only 13.3% originated from the testis. Out of that, 51.1% of neoplasms were histologically proved as schwannomas, 44.4% as neurofibromatosis, and 4.4% as malignant peripheral nerve sheath tumors. The majority of patients presented with atypical symptoms such as scrotal swelling (51.1%), while only 4.4% of patients were asymptomatic. Ultrasonography is the diagnostic modality of choice (97.2%) for the detection of primary lesion, while magnetic resonance imaging and computed tomography comprise supplementary diagnostic tools. Surgical excision of the mass was the preferred type of surgery performed (75.6%), whereas orchiectomy was performed only in 22.2% of patients. Intrascrotal tumors of nerve origin are extremely rare neoplasms that present mainly in middle-aged males. Increased clinical suspicion is required for accurate diagnosis of this rare entity.

Solitary Intrascrotal Plexiform Neurofibroma in a 10-Year-Old Male

Intrascrotal neurofibromas are extensive tumors that grow from peripheral nerves within the scrotum and are exceedingly rare among the benign extratesticular tumors. Though the risk is low, potential for malignancy and patient discomfort make diagnosis and surgical evaluation imperative. Pediatric neurofibromas are typically only associated with neurofibromatosis type 1. However, herein, we describe a rare case of a benign, intrascrotal plexiform neurofibroma in a 10-year-old male who lacks any stigmata associated with this genetic disorder. Diagnostic and surgical challenges as well as histopathological findings are discussed.

Atypical scrotal masses: Surgical surprise

We present three unusual cases of atypical scrotal lesions in children. The first was a firm left scrotal mass with the testis indistinguishable. The second with apparently a large hydrocoele, which was a cyst, and the third with multiple nodular lesions, pushing the left testis into the right hemiscrotum. These turned out to be a pigmented neuroectodermal tumour, a lymphatic malformation and neurofibromas respectively. Paediatric surgeons should be aware of such surgical surprises.

A case report of solitary neurofibroma of the Vas deferens

Solitary neurofibroma of the male genital tract is a rare benign peripheral nerve sheath tumor which is considered to originate from the Schwann cell. Neurofibroma of the male genital tract has been reported extremely rarely in the literature. We present a case of neurofibroma of the Vas deferens in a 59-year-old patient. The clinical and pathological data of a patient with Neurofibroma of the Vas deferens were retrospectively analyzed and radical resection of the left side spermatic cord tumor was performed. This case report will help in understanding this rare tumor.

Neoplastic diseases of the spermatic cord: an overview of pathological features, evaluation, and management

Extracellular tumors found with the spermatic cord, known as neoplasms, are usually identified to be benign. However, the accurate and timely diagnosis of spermatic cord masses is highly crucial, especially when most results are often overlooked or unclear. In this review, we discuss the anatomy and embryology of the spermatic cord. Upon rooting these fundamental concepts, we discuss an array of benign and malignant neoplastic tumors, including their origin, pathological features, clinical evaluation and management, as well as other case-specific characteristics of unique presentation. Many of these neoplasms are based on local neurological, vascular, muscular, bone, soft tissue, or lymphatic origin, while others have metastasized from particular areas of the body.

Solitary Neurofibroma Of The Spermatic Cord: A Case Report

We report the ultrasound, computerized tomography, positron emission tomography and magnetic resonance imaging findings of a 38-year-old man with a biopsy proven solitary neurofibroma of the spermatic cord. Solitary neurofibromas of the male genital tract are exceedingly rare benign peripheral nerve sheath neoplasms composed of Schwann cells and fibroblasts. In contrast to schwannomas they are not bound by a capsule thus allowing infiltration between the nerve fascicles. Although they are benign lesions whose potential for malignant degeneration is very low, especially in the absence of neurofibromatosis type 1, accurate diagnosis is important as neurofibromas in this location can cause significant morbidity and psychological distress. Despite the extensive differential diagnosis of masses in the male inguinal canal, including both benign and malignant entities, a diagnosis of benign peripheral nerve sheath tumor can be potentially suggested based on imaging, particularly if MRI is performed. Surgical resection is the treatment of choice and the final diagnosis should be provided by histopathology, as was the case with this patient.

A case of diffuse bilateral scrotal neurofibroma in a rabbit

This report details a rare case of diffuse bilateral scrotal neurofibroma complicated by hindlimb paralysis in a rabbit. The animal was evaluated for unusual bilateral scrotal enlargement. After physical examination, ultrasound scan, radiography, computed tomography and laparoscopy, surgical exploration of the scrotum was undertaken. A homogeneous rubbery firm mass was revealed in contact with the subcutaneous tissue expanding to the entire scrotum without involving the testicles. The mass was excised and diagnosed as diffuse scrotal neurofibroma based on histological and immunohistochemical findings (S-100 antibody positive). Over the following month, progressive neurological signs (faecal incontinence, flaccid bladder and hindlimb paralysis) were observed. After excluding central nervous system infection with Encephalitozoon cuniculi, expansion of the neurofibroma to the vertebral canal causing compression of the spinal cord was suspected, although not histopathologically verified.

Intrascrotal multiple neurofibromas unassociated with neurofibromatosis: a case report

We report the case of a 33-year-old male with multiple intrascrotal neurofibromas not associated with neurofibromatosis, treated by surgical excision.
