Glomus tumors are benign neoplasms that arise from neuromyoarterial glomus bodies. They represent around 1-5% of all soft-tissue tumors. High temperature, sensitivity, and pain and localized tenderness are the classical triad of symptoms. Most glomus tumors represent in the subungual area of digits. Extradigital glomu…

Glomus tumors in the gastrointestinal tract are unusual, as the previous series in the literature have been mainly limited to the stomach. Less than 10 cases of esophageal glomus tumors have been described in the literature. Oncocytic glomus tumors are a recently identified, rare variant of the glomus tumor. We report…

Glomus tumor is a rare benign mesenchymal neoplasm derived from the glomus body, an arteriovenous shunt mainly located in dermis and subcutis. The most common localization of this tumor is extremities, especially nailbed. Glomus tumor in the gastrointestinal system is a rare condition. Here we report a gastric glomus…

In this article, we study the Trivariate Fibonacci and Lucas poly- nomials. The classical Tribonacci numbers and Tribonacci polynomials are the special cases of the trivariate Fibonacci polynomials. Also, we obtain some properties of the trivariate Fibonacci and Lucas polynomials. Using these properties, we give some…

Glomus tumours around the shoulder are very rare. To the best of our knowledge, seven cases have been reported to date. We present a case with special emphasis on its localization and time of appearance. Contrary to the related reports in the literature, the lesion was of short duration and it became symptomatic just…

Abstract Lichens are understood to be symbiotic organisms consisting of mycobiont and photobiont partners. This mutual partnership results in the production of unique secondary metabolites, which are used in contemporary pharmacy and medicine. The purpose of this study is to explore the uses of lichens in a particular…

Research in history of mathematics gained momentum in the past two decades in Turkey. The present paper aims to describe the patterns in the history of mathematics research in Turkey and to analyse the research in Turkey using a mathematics education framework. The qualitative paradigm and a case study design are used…

We know that Bonnet surfaces are the surfaces which can admit at least one non-trivial isometry that preserves the principal curvatures in the Euclidean three-dimensional space.In this study, firstly, we have examined the required conditions for the canal surfaces, which are called the special swept surfaces, to be Bo…
