Pleomorphic lipoma is an uncommon, pseudosarcomatous lesion. It is characterized by the pleomorphic appearance on cytology and histology, follows a benign course, with a low rate of recurrence after complete excision, and has no risk of metastasis. Here, we describe a case of pleomorphic lipoma/spindle cell lipoma in a 41-year-old man who presented with a slow-growing mass on the inner aspect of the left thigh. On fineneedle aspiration cytology, it was reported as a cellular nerve sheath tumour followed by a wide excision sample sent for histopathological examination, which revealed spindle cells exhibiting pleomorphism with mature adipocytic cells and multinucleated floret cells in a myxoid background. It was reported as pleomorphic lipoma on histological examination.
Chondroid syringoma is also known as mixed tumour of the skin. It is a rare, biphasic cutaneous neoplasm similar to pleomorphic adenoma of salivary glands. Because of its rarity, many cases are misdiagnosed in the initial stages as cysts or other cutaneous adnexal neoplasms and are often identified only after being sent for histopathological examination.Although it usually presents in middle and older aged patients, we are presenting three younger patients with Chondroid syringoma, located over the back, nose and cheek, respectively.
In recent years, indoor scene recognition has attracted much attention and its research has rapidly expanded by not only engineers but also neuroscientists, since it has many potential applications in computer vision communication and automatic access control system. Especially, indoor scene recognition is an important part of computer vision and feature recognition as the first step of automatic uninterrupted robotic movement or computer vision applications like automatic interior designing algorithms. However, the indoor scene detection is not straightforward because it has lots of variations of image appearance, such as light effect, occlusion, image orientation, illuminating condition and object variety. Many novel methods have been proposed to resolve each variation listed above. For example, the template-matching methods are used for indoor scene localization and detection by computing the correlation of an input image to a standard and training scene appearance or pattern. The feature invariant approaches are used for feature detection of bed, chair, cabinet, table, door, electrical or electronic items, etc. The appearance-based methods are used for indoor feature detection with support vector machine and information theoretical approach. Nevertheless, implementing the methods altogether is still a great challenge. Fortunately, the images used in this project have some degree of uniformity thus the detection algorithm can be simpler: first, the all the faces are vertical and have frontal view; second, they are under almost the same illuminate condition. This project presents an indoor scene detection technique mainly based on the appearance based feature segmentation, SVM training and SVM classification methods to recognize the indoor scenes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
