A rare case of a median nerve schwannoma: Case report

A median nerve schwannoma is an uncommon type of tumor that develops from Schwann cells in the peripheral nerves. We present a case report of a young prisoner with a rare median nerve schwannoma presenting as a swelling on the anterior aspect of the right wrist along the radial edge, with associated paresthesia and a positive Tinel's sign. The case was diagnosed using MRI which showed the target sign of biphasic contrast enhancement in both the mass's center and periphery as well as distinct encapsulation. The mass was managed with surgical excision which confirmed the mass to be a neurilemmoma. The radiological finding for neurinomas are not specific and the diagnosis cannot be established unless an excision is made, as neurinomas share common radiological signs with other peripheral nerve tumors and vascular tumors. This case highlights the importance of considering nerve sheath tumors, however rare, in the differential diagnosis of wrist masses, even in young patients with no history of trauma.

Neuroendocrine breast carcinoma: The importance of the correlation between histological and radiological findings

Neuroendocrine breast carcinoma (NEBC) is an uncommon and malignant breast lesion. The absence of proper testing for this type of breast cancer carcinoma exacerbates this paucity. Additionally, only scant evidence of these tumors is present because of the repeated revisions in their diagnostic criteria throughout time. This case report highlights the importance of the correlation between histological and radiological findings in the diagnosis and treatment of neuroendocrine breast cancer. We describe the clinical, radiological, and histological characteristics of a patient diagnosed with neuroendocrine carcinoma. The breast parenchyma was penetrated by a carcinomatous tumor growth that contained trabeculae and lobules, exhibiting mild cytonuclear atypia, and having a low mitotic index. This report emphasizes the value of a multidisciplinary strategy for precise diagnosis and treatment planning.

Mandibular Metastasis in Neuroblastoma in a 3 Year-Old Child: A Case Report

Neuroblastomas commonly metastasize to the cranium and orbit, although other facial bones were less implicated. In this report we present a 3 years old child with metastatic neuroblastoma to the mandible that presented with swollen right jaw. The first assessment of the head with computed tomography revealed soft tissue mass with permeative lytic changes of the osseous structures centered on the right mandible, as well as osteo-meningitis metastases. These masses were proven to be metastatic lesions from intra-abdominal neuroblastoma of the right adrenal gland. Over the previous several years, only 29 cases of neuroblastoma metastasis to the mandible have been reported in the literature.

Central nervous system manifestations of neurofibromatosis type 2: A case report

Neurofibromatosis type 2 (phacomatosis) is a rare inherited autosomal dominant condition defined by the development of numerous central neuronal tumors. In addition to classic intracranial schwannomas, intracranial and spinal meningiomas, and intramedullary ependymomas, it can be associated with a few cutaneous abnormalities. In this report, we discuss the case of a 21-year-old female who was examined for persistent headache with cutaneous masses and bilateral hearing loss. Magnetic resonance imaging of the cranium and the whole spine detected multiple meningiomas, intracranial, and intramedullary tumors.

Kasabach-Merritt syndrome complicating a giant hemangioma of the liver: A case report

Liver hemangiomas are the most common benign tumors of the liver with a prevalence of 1%-20% according to autopsy series. They can in some cases reach measurable sized. These giant hemangiomas can have fatal complications such as hemorrhaging, intraperitoneal rupture, mass of effect and Kasabach-Merritt syndrome. We report an adult case in which recent right quadrant pain revealed a liver hemangioma associated with Kasabach-Merritt syndrome.
