https://www.selleckchem.com/products/reversine.html In the musculoskeletal system, tumor-like lesions may present similar imaging findings as bone and soft tissue tumors and can be defined as tumors on radiologic examinations. Misinterpretation of the imaging findings can lead to inappropriate clinical management of the patient.There is still some debate regarding the pathophysiology and origin of tumor-like lesions that include congenital, developmental, inflammatory, infectious, metabolic, reactive, posttraumatic, post-therapeutic changes, and some miscellaneous entities causing structural changes. Although tumor-like lesions are historically defined as non-neoplastic lesions, some of them are classified as real neoplasms.We discuss a spectrum of entities mimicking tumors of bone and soft tissues that include various non-neoplastic diseases and anatomical variants based on imaging findings.Most orbital diseases are rarely diagnosed in the clinic. Because the consequences for the eye can be severe, it is important to recognize the signs of orbital disease early in order to initiate the correct diagnostic and therapeutic steps in good time. This article presents the basics of the systematics, diagnostics and therapy of orbital diseases in preparation for the specialist examination for ENT medicine. Some orbital diseases are typical manifestations of systemic diseases (e. g. Graves' disease) or typical complications of diseases in the vicinity of the orbit (e. g. orbital complications from inflammatory or tumorous sinus diseases). The diseases of the lacrimal system and the eyelids as well as their therapy are closely related to the diseases of the orbit. Basically, it can be said that the diagnosis and therapy of orbital diseases should always be carried out on an interdisciplinary basis, whereby the involvement of the ophthalmologist is of particular importance.Due to development of molecular techniques at hand, the number of genomic sequence variants detected in p
