Primary neuroendocrine tumor of the testis
Urology Annals, 2014 Testicular neuroendocrine tumor is rare. It accounts for less than 1% of all testicular neoplasms. More than 60 cases have been published in the literature.

A Rare Component of Psammomatous Meningioma in a Testicular Teratoma
Case Reports in Pathology, 2013 We report a case of a psammomatous variant of meningioma arising in a pure and mature testicular teratoma. At immunohistochemistry, the meningiomatous component showed epithelial membrane antigen, S100 protein, and vimentin positive.

Computational Intelligence Approach to Improve the Classification Accuracy of Brain Neoplasm in MRI Data [PDF]
arXiv, 2021 Automatic detection of brain neoplasm in Magnetic Resonance Imaging (MRI) is gaining importance in many medical diagnostic applications. This report presents two improvements for brain neoplasm detection in MRI data: an advanced preprocessing technique is proposed to improve the area of interest in MRI data and a hybrid technique using Convolutional ...

Neoangiogenesis in the dynamics of testicular seminoma progression
Journal of Education, Health and Sport, 2019 Testicular germ cell tumors (TGCT) is a group of neoplasms which develop from the germ cell epithelium and account 94-96% of all testicular tumors. Seminoma is the most common testicular germ cell neoplasm and accounts for about 50% of all TGCT.There is ...

Mathematical models for order of mutation problem in myeloproliferative neoplasm: non-additivity and non-commutativity [PDF]
arXiv, 2023 In some patients of myeloproliferative neoplasm, two genetic mutations can be found: JAK2 V617F and TET2. When one mutation is present or not, the other mutation has different effects on regulating gene expressions. Besides, when both mutations are present, the order of occurrence might make a difference.

Fine needle aspiration cytology and cell block in the diagnosis of seminoma testis
Journal of Cytology, 2011 Testicular neoplasms which show a wide variety of morphologic types, comprise a small proportion of malignancies. Early identification and treatment is essential for achieving long term survival.

Order-of-mutation effects on cancer progression: models for myeloproliferative neoplasm [PDF]
arXiv, 2023 We develop a modeling framework for cancer progression that distinguishes the order of two possible mutations. Recent observations and information on myeloproliferative neoplasms are analyzed within our framework. In some patients with myeloproliferative neoplasms, two genetic mutations can be found, JAK2 V617F and TET2.
