Background: Benign neural tumors, including schwannomas, neurofibromas, and meningiomas, are non-malignant growths originating from nerve tissues. Despite their benign nature, these tumors can cause significant morbidity due to their location and potential for recurrence, posing challenges in clinical management. Understanding the clinico-pathologic characteristics of these tumors is essential to optimize treatment strategies and improve patient outcomes. Aim: This study aims to analyze the clinical presentations, histopathological features, and surgical outcomes of benign neural tumors, focus

Maximum breast cancer cells are eventually form a lump or mass called a tumor. Moreover, some tumors are cancerous and some are not cancerous. The cancerous tumors are called malignant and non-cancerous tumors are called benign. The benign tumors are not dangerous to health.

Abstract Over a 17-year period, 56 patients with 57 tumors involving the brachial plexus were operated upon. The 40 neural sheath tumors included 26 neurofibromas, 8 schwannomas, 4 malignant neural sheath tumors, 1 fibrosarcoma, and 1 meningioma. Nine of the neurofibromas were associated with von Recklinghausen's disease (VRD), and 2 others were what was termed regionalized neurofibromatosis characterized by involvement of one limb with extension along the course of one or more plexus elements. Seventeen tumors were not of neural sheath origin; 7 were benign and 10 were metastatic malignant tu

Eyelid tumors in about 80–95% of cases belong to benign lesions. Because of the complex anatomy of the eyelids and the resulting diversity of potential sites of initiation of the neoplastic process, as well as because of the morphological similarity of the observed lesions, making a correct diagnosis at the initial stage of the diagnostic process is challenging. Neural tumors originating from peripheral nerves and neuroendocrine cells are rare neoplastic lesions of the eyelids.

Neuroendocrine neoplasms of the larynx have either an epithelial or a neural basis. The former are more numerous and are classified as typical or atypical carcinoids and small cell neuroendocrine carcinomas. Paraganglioma is the sole type of neural neuroendocrine neoplasm. There is a significant worsening of prognosis from typical carcinoid to small cell neuroendocrine carcinoma, with the latter having a dismal 5-year survival rate regardless of therapy.

Object The operative management of combined intrapelvic and extrapelvic sciatic notch dumbbell-shaped tumors is challenging. The relatively rare occurrence of these tumors and the varied extent of disease have made it difficult for surgeons to establish definitive surgical indications or predict favorable neurological outcomes based on preoperative imaging data. Methods In the past 3 years, the authors treated five patients presenting with radiating leg pain as a result of benign sciatic notch dumbbell-shaped tumors. These tumors in three patients with unilateral leg symptoms were considered u

Carotid body tumors (CBT) are a rare form of paragangliomas of the head and neck. They are described as rare, slow-growing, mostly benign, clinically silent tumors of neural crest cells. This tumor should be considered as a differential diagnosis when evaluating a lateral neck mass. A report of a rare case, a carotid body tumor, is presented that was incidentally noted as a lateral neck mass during a screening sonogram. A mass located at the level of the left carotid bifurcation demonstrated significant vascular flow with the use of contrast enhanced ultrasound (CEUS) techniques. Computed tomo

Choroid plexus papillomas (CPPs) are typically benign tumors that can occur in any age group but are more commonly found in pediatric patients. Although these tumors are benign, there are several reports in adult patients of distant metastases present either at the time of diagnosis or occurring months to years after initial resection. Here, the authors report the case of a 14-year-old boy who presented with symptoms of elevated intracranial pressure due to obstructive hydrocephalus that was caused by a large fourth ventricular mass. Preoperative imaging included a full MRI of the spine, which

Although most pituitary tumors are benign, some are invasive or aggressive. In the absence of specific markers of malignancy, only tumors with metastases are considered malignant. To identify markers of invasion and aggressiveness, we focused on prolactin (PRL) tumors in the human and rat. Using radiology and histological methods, we classified 25 human PRL tumors into three groups (non-invasive, invasive, and aggressive–invasive) and compared them with a model of transplantable rat PRL tumors with benign and malignant lineages.

Neurofibromatosis type 1 (NF1) is a genetic disorder that predisposes individuals to develop benign and malignant tumors of the nerve sheath. Understanding the signatures of cancer stem cells (CSCs) for NF1-associated tumors may facilitate the early detection of tumor progression. Background: Neural crest cells, the cell of origin of NF1-associated tumors, can initiate multiple tumor types, including melanoma, neuroblastoma, and schwannoma. CSCs within these tumors have been reported; however, identifying and targeting CSC populations remains a challenge. Results: This study aims to leverage e

Our objective in this paper is to introduce the efficacies of texture in the interpretation of color skin images. Melanoma is the most malignant skin tumor, growing in melanocytes, the cells responsible for pigmentation. This type of cancer is nowadays increasing rapidly; its related mortality rate increases by more modest and inversely proportional to the thickness of the tumor. This rate can be decreased by an earlier detection and better prevention. Using the features of skin tumors, such as color, symmetry, and border regularity, an attempt is made to determinate if the skin tumor is a mel

Schwannomas are benign tumors of neural crest origin that can arise from any nerve. Ancient Schwannomas are an exceedingly rare but benign variant characterized by degenerative changes on histopathology, often mimicking malignancy. Here, we report a case of a 45-year-old man presenting with a painful swelling in the left hand. Magnetic resonance imaging (MRI) suggested Schwannoma. Surgical excision revealed the tumor arising from a branch of the ulnar nerve. Histopathological examination confirmed the diagnosis of ancient Schwannoma through immunohistochemistry.

Fewer than 9% of schwannomas are located in the mediastinum. Posterior mediastinal schwannomas originate from neural crest cells and typically from the intercostal nerves.
