Background: Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). Case Presentation: A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initi...

the endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. they are rare neoplasms, diagnosed in most instances by microscopy. although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in end...

thyroid nodules are common, occurring in almost two-thirds of some populations; among these only about 7% are malignant. the most important question with any new discovered thyroid nodule is, “is this malignant?” the main arbiter of malignancy or benignity remains fine needle aspiration and the mainstay of treatment surgery. but given the resources involved, doing an fnac or surgery in every di...

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.

Sister Mary Joseph Nodule is an eponymous term referring to umbilical nodule harbouring malignant metastatic cancer. It a physical finding that uncommon yet significant since it indicates the late manifestation of variety deep-seated abdominopelvic malignancies. This review article briefly revisits historical background, epidemiology, anatomical routes metastasis, clinical presentation, differe...

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...
