We investigate the problem of diagnostic lung nodule classification using thoracic Computed Tomography (CT) screening. Unlike traditional studies primarily relying on nodule segmentation for regional analysis, we tackle a more challenging problem on directly modelling raw nodule patches without any prior definition of nodule morphology. We propose a hierarchical learning framework--Multi-scale ...

Primary cutaneous CD30+ T cell lymphoma is rare lymphoma originally in and confined to the skin. These lymphomas usually present as a large solitary and often ulcerated nodule. Its prognosis is a good and has a good response to radiotherapy. We report a 34- year- old man who had primary cutaneous CD30+T cell lymphoma on his face, which presented as an ulcerated nodule.

Congenital umbilical cord hernia is fairly common in infants and it is rarely associated with other anomalies. Sometimes, large umbilical cord hernia is confused with Small omphaloceles. We report an unusual case of umbilical cord hernia associated with patent vitello-intestinal duct (PVID), and Meckel's diverticulum underwent surgery and discharged with good general condition.

We present a case of hepatocellular carcinoma (HCC), showing an atypical "nodule-in-nodule" appearance on ultrasonogram (US). In general, a "nodule-in-nodule" appearance is found as a hyperechoic tumor containing a hypoechoic nodule. In the present case, however, there was a hyperechoic subnodule in the center of the tumor, which was surrounded by a hypoechoic tumor area. Histologically, the su...

Metastatic cancer of the umbilicus, known as Sister Mary Joseph nodule, is typically associated with visceral malignancy. It is an uncommon and rare presentation. It indicates disseminated disease and poor prognosis. Physicians need to be aware of this rare clinical condition so that they can promptly diagnose the primary cancer.

PURPOSE To determine the prevalence, clinical characteristics and nature of subfoveal nodules in Coats' disease and the associated impact on the long-term visual outcome. METHODS Consecutive cases of Coats' disease with foveal exudation were retrospectively reviewed. The presence of a subfoveal nodule or macular fibrosis was recorded. Clinical characteristics, retinal imaging, and outcome wer...
