Lesions

A 65-year-old white male presents to his primary care physician, at the urging of his wife, for the evaluation of numerous chronic skin lesions. These lesions started approximately two years ago and have recently started to become thick, scaly, and crusty with areas that feel both dry and rough. Patient has no other significant past medical or surgical history. He takes a baby aspirin daily. He takes no other medications and has no allergies. The patient has a family history of “various cancers.”

Introduction Solar keratosis also known as actinic keratosis is a pre-malignant lesion of the skin that confined to the epidermis and has the potential to develop into squamous cell carcinoma (SCC) (1, 2). Solar keratosis is a common skin condition that is associated with cumulative sun exposure, increased susceptibility to sun exposure and increased with age (2, 3). Other risk factors include light-skinned individuals, outdoor workers, previous history of burns, areas directly to sun exposure and

Hemangioma is the most common non-cystic benign hepatic lesion. Depending on imaging findings, hepatic hemangiomas can be categorized as typical and atypical. Typical hemangiomas comprised of three distinct histological subtypes, including (i) the cavernous hemangioma, (ii) the capillary hemangioma and (iii) the sclerosed hemangioma (1). The atypical group includes various categories such as giant and heterogeneous large hemangiomas (2, 3). A.1.Typical hepatic hemangiomas Ultrasonography (US): Generally

2.1. Heterogeneous large and giant hepatic hemangiomas At US, large hemangiomas seem heterogeneous. With using non-contrast CT, the lesion may be seen hypoattenuating and heterogeneous with low attenuated central areas. After administration of contrast material, the filling is incomplete during the portal venous and delayed phases. On T1-weighted images, the lesion is observed as a marginated hypointense mass containing hypointense septa and a hypointense cleft. On T2-weighted images, the internal

posterior (SLAP) lesions can occur either in isolation or in conjuncture with a broad spectrum of other shoulder injuries, such as rotator cuff tears, glenohumeral instability, and isolated biceps tendon ruptures.1 The detection of SLAP lesions has developed with the improvements in diagnostic imaging, but physical examination tests remain nonspecific.1 Therefore, the purpose of this paper is to review three different research studies pertaining to the diagnostic accuracy of SLAP lesion injuries. In

Tumors and tumor-like lesions usually been discussed in a large category, because their appearances sometimes are similar and make differential diagnosis extremely difficult. But tumors are non-neoplastic lesions, while tumor-like lesions are not, therefore, treatment and prognosis of these two groups of disorders are usually different. The incidences of tumors and tumor-like lesions have big differences in literature, this may due to the classification of benign, malignant and non-neoplastic conditions

most endometriosis lesions. Perhaps the limited sensitivity and specificity of MRI also could be attributed to inherent differences between MRI and laparoscopy. Magnetic resonance imaging provides a series of cross-sectional images at 5-mm intervals, whereas laparoscopy offers a panoramic view of the peritoneal surfaces that are not in the same plane and are seen after distending the abdomen with carbon dioxide. This study also demonstrates the gap between surgical and histologic identification of

After the images are taken, a radiologist can manipulate the digital images by inverting, magnifying, and changing the contrast to double-check the site of the lesion. The computer will then graph the site of the lesion by using x, y, and z coordinates. Once the imaging has been done, the next step is setting up the needle. A sterile needle guide is attached to a movable post at the stage assembly. The biopsy instrument is then attached

Introduction Tuberculosis is an infectious disease that has afflicted individuals from the Old World for several thousands of years. This has been well documented in the archaeological record. However, the origins and development of tuberculosis in the New World have been the subject of multiple controversies. These controversies have stemmed from the discussion of whether or not Europeans introduced tuberculosis to the Americas. Evidence from South America has clearly shown that tuberculosis was

may also be singular and idiopathic. The age of onset plays a crucial role in differentiating the lesions and the course of treatment following diagnosis. Visual symptoms can range from being asymptomatic, to mild visual disturbances, to enucleation in the worst cases- which are associated with systemic conditions. The appearance of astrocytic hamartomas are comparable to a variety of other lesions associated
