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.

Safety and Efficacy of Endoscopic Treatment of Solitary Gastric Neurofibroma

Purpose

The studies on solitary gastric neurofibroma (GN) consist of only individual case reports, with little data and relevant information. We aimed to summarize the clinical features, endoscopic features, imaging findings, and pathological features and study the safety and efficacy of endoscopic treatment of solitary GN.

Patients and Methods

We retrospectively collected and analyzed clinical data of patients who underwent endoscopic treatment in Department of Gastroenterology of a well-known tertiary hospital from August 2007 to September 2019 and were accurately diagnosed as having solitary GN.

Results

A total of 788 patients with gastric submucosal tumors underwent endoscopic treatment, among whom 11 patients were found to have solitary GNs. The incidence of solitary GNs was 1.4%. All 11 patients were treated with endoscopy. Five patients underwent endoscopic full-thickness resection (EFTR) and six patients underwent endoscopic submucosal excavation (ESE). The en bloc resection rate of the 11 lesions was 100.0%. The median endoscopic operation time was 80 minutes. Average length of hospital stay was 6.4 ± 1.6 days. The median follow-up time was 29 months. No recurrence, distant metastasis, or disease-related death occurred during the follow-up.

Conclusion

EFTR and ESE can serve as feasible, safe, and effective treatments for solitary GN.

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.

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

Solitary Neurofibroma of the scrotum is an extremely rare benign tumor, particularly when it is not associated with neurofibromatosis type I. To the best of our knowledge, less than 10 cases have been reported in the English literature. Herein, we report a 52-year-old man with the diagnosis of scrotal solitary neurofibroma.

Solitary intrascrotal neurofibroma: a case diagnosed on aspiration cytology

Solitary neurofibroma of the scrotum is exceedingly rare and very few cases of this unusual occurrance have been reported till date. None of the previously reported cases had a preoperative cytologic diagnosis. A young man presented with an eight-month history of right scrotal swelling. Fine-needle aspiration cytology showed a spindle cell tumor with fibrillary matrix and wavy slender nuclei. A cytologic diagnosis of benign nerve sheath tumor was rendered. The patient underwent surgical excision of the mass and histopathologic examination confirmed the diagnosis of a neurofibroma. This case is the first reported instance of aspiration cytologic diagnosis of intrascrotal neurofibroma. This rare tumor should be considered in the cytologic differential diagnoses of testicular and paratesticular tumors.

Solitary colonic neurofibroma in a patient with transient segmental colitis: Case report

Neurofibromas of the large bowel are very rare and usually are part of the colonic involvement in neurofibromatosis type 1 (Nf1, von Recklinghausen’s disease). Solitary neurofibromas of the colon are extremely rare. We describe a case of an isolated neurofibroma that was found in the large bowel of a patient who suffered from segmental colitis and presented with bloody diarrhea. A review of the literature is also included, concerning the disclosure of isolated neurofibromas in the gut and other body parts and the type of gastrointestinal involvement in von Recklinghausen’s disease.
