Ewing's sarcoma (ES) and primitive neuroectodermal tumour (PNET) are now considered to be the same tumour and usually occur in long bones. Extraskeletal Ewing's sarcoma is an extremely rare neoplasm, accounting for 1% of soft tissue sarcomas, with most common location in the thorax. Gallbladder cancer (GBC) represents the most common type among the biliary tract cancers with a poor prognosis ev...

Introduction. Aggressive angiomyxoma is a rare mesenchymal neoplasm. Although benign in the majority of the cases, these neoplasms usually present a locally infiltrative nature and high rates of recurrence. Due to its rarity, misdiagnosis is a common problem. Case Presentation. We present one case of aggressive angiomyxoma in a 25-year-old pregnant woman. The patient presented with a large vagi...

Purpose Ameloblastoma is a non-encapsulated and slow-growing tumor with high recurrence rate. Orbital involvement by this neoplasm is an extremely rare entity. In this study, we present a systematic review on this situation along with clinical and paraclinical features of a case. Methods An electronic search was conducted on major medical sources. Data of the cases in the literature in additi...

This study investigates the presence of deterministic dependencies in international stock markets using recurrence plots and recurrence quantification analysis (RQA). The results are based on a large set of free float-adjustedmarket capitalization stock indices, covering a period of 15 years. The statistical tests suggest that the dynamics of stock prices in emerging markets is characterized by...

Ameloblastoma is a benign yet locally invasive odontogenic neoplasm, characterised by slow growth and painless swelling. The treatment for ameloblastoma varies from curettage to en bloc resection, with recurrence commonly occurring. safety margin of resection hence essential avoid recurrence. Understanding the three-dimensional anatomy reconstruction mandibular defects after tumour often poses ...

Abstract A newly described entity called “calcified chondroid mesenchymal neoplasms” includes neoplasms with variable amounts of calcification and FN1 fusions [Liu et al, Mod Pathol 2021]. We report a case left temporal bone giant cell granuloma-like lesion that also shows an FN1-TEK fusion. Close monitoring MRI images after surgery has showed no recurrence. Case report: 33-year-old male develo...

Bladder tumour, especially urothelial neoplasm, is a very rare condition in paediatric age. That why true and accurate information on biological grade of malignancy and, correspondingly, the surgical management absent. However, majority physicians take view that this type tumour has low malignization recurrence, even after endoscopic excision neoplasm patients. Purpose - to describe clinical ca...

the neurilemmoma is a benign neoplasm of schwann cell origin. one of the histopathologic subtypes of this tumor is ancient schwannoma which is characterized by degenerative alterations including cystic change, calcification, hemorrhage, and hyalinization. intraosseous schwannomas especially ancient ones are rare tumors. here we present a case of intraosseous ancient schwannoma in the lower jaw ...

Solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare neoplasm reported to have a favourable prognosis because of its slow-growing behaviour. Ignored and misdiagnosed in the past, SPN has recently been increasingly studied. Its clear cell variant creates challenges in distinction from other clear cell tumours in the pancreas. We report a 31-year-old Cambodian woman who presented with a...
