Abstract:

Neurofibroma of the prostate is an extremely rare benign tumor, particularly when it is not associated with neurofibromatosis-I (NF-1). This study aimed to report the case of a 44-year-old man who presented with dysuria for about 4 years. Magnetic resonance imaging (MRI) showed a mass in the prostate with “target sign” on T2-weighted imaging. The mass was surgically excised, and histopathological findings revealed a neurofibroma. No clinical or laboratorial manifestations of NF-1 were identified. Also, no local recurrence occurred after the 3-month follow-up. This was the first case of prostate solitary neurofibroma without NF-1, and the “target sign” on MRI could supply some significant implications in the diagnosis.

A Large Solitary Hemangioblastoma of the Lateral Ventricles: A Case Report and Literature Review

Hemangioblastoma (HB) in the supratentorial region of the brain is rare and only a few cases are reported on intraventricular HB. HB of the lateral ventricles is even rarer. We present a case of a 30-year-old man with generalized tonic clonic seizures. The brain computed tomography showed a 5.5 cm heterogeneous mass extending into both lateral ventricles with partial enhancement. Based on the s...

Solitary submucous neurofibroma of the mandible: review of the literature and report of a rare case

Solitary neurofibroma is a rare benign non-odontogenic tumor. Particularly in the oral cavity, neurogenic tumors are rare, especially if they are malignant. Neurofibromas may present either as solitary lesions or as part of the generalised syndrome of neurofibromatosis or von Recklinghausen's disease of the skin. Clinically, oral neurofibromas usually appear as pediculated or sessile nodules, w...

PRIMARY PANCREATIC LYMPHOMA: A CASE REPORT AND LITERATURE REVIEW

Primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of B cell non-Hodgkin's lymphoma that predominantly involves the pancreas. It comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-Hodgkin's lymphomas. This lymphoma is almost never suspected clinically. It is usually diagnosed by surgical exploration for suspected adenoca...

Presacral solitary giant neurofibroma without neurofibromatosis type 1 presenting as pelvic mass--case report.

A 35-year-old woman presented with a solitary neurofibroma in an unusual presacral location without neurofibromatosis manifesting as bilateral chronic sciatica for 2 years. She was initially considered as having a giant right ovarian mass, but was referred with a prediagnosis of solitary giant sacral nerve sheath tumor. The initial differential diagnosis was based on neuroimaging. A right-sided...
