Vasculitis is an inflammatory process occurring primarily on the vessel wall. It results in vessel wall destruction and subsequent hemorrhagic and ischemic events. Skin is the most common target organ for vasculitis.1,2,3,4 Cutaneous vasculitis includes vasculitis of the dermal small vessels5 and subcutaneous small muscular vessels.6 It can be a self-limited benign disease restricted to the ski...

Investigators from Sainte Justine Hospital (Montreal), Montreal Neurological Hospital and Institute, King's College Hospital (London), and John Radcliffe Hospital (Oxford) retrospectively reviewed medical records, autopsy reports, and genetic studies containing "Polymicrogyria."

stated, " almost exclusively non-sulphated". This does not detract, however , from the important finding of intense focal sulphomucin positivity in our case. We also agree that increased sulphomucins may be found in other epithelial sites in non-cystic fibrosis inflammatory disorders. In our paper we made no attempt to attribute directly the increased viscosity and other properties of cystic fi...

Spindle cell proliferations of diverse types which vary greatly in their behavior may occur in the urinary bladder. Some of them such as the inflammatory pseudotumor and the postoperative spindle cell nodule are reactive and clinically benign although they may be responsible for significant symptoms. On the other hand, certain other lesions such as sarcomatoid carcinomas are typically highly ma...

HIGHLIGHT Histopathology of birdshot retinochoroidopathy Birdshot retinochoroidopathy is a chronic posterior segment inflammatory disease with a characteristic clinical presentation and strong correlation with the HLA-A29 antigen. 1 2 In this report, we describe the his-topathological findings in the eye of a patient with this disease. A 49 year old white man was referred to the Proctor Medical...

Hematoxylin and Eosin stained histopathology image analysis is essential for the diagnosis and study of complicated diseases such as cancer. Existing state-of-the-art approaches demand extensive amount of supervised training data from trained pathologists. In this work we synthesize in an unsupervised manner, large histopathology image datasets, suitable for supervised training tasks. We propos...

The accurate histopathological evaluation, the diagnosis, and the assessment of level of invasion of malignant melanoma have assumed a role of paramount importance in defining need for further surgery, a chemotherapeutic or immunotherapeutic approach to management, and prognosis. The classification of melanoma into lentigo maligna melanoma, superficial spreading melanoma, and nodular melanoma a...

  Background and Objective: Ovarian tumors are among the most frequent pathologic conditions in gynecologic practice and a frequent cause of hospitalization and surgery. The aim of this study was to determine histologic distribution of benign operated masses especially functional ovarian cysts. Material and Methods: Benign ovarian files of operated patients (2961 cases) in 20 tertiary and sec...
