Sclerosing orbital lesions: broadening the differential diagnosis of " idiopathic sclerosing pseudotumor "
Sclerosing orbital lesion(the biopsy revealed it to be Erdheim-Chester disease)Sclerosing lesions of the orbit can present a diagnostic conundrum. Often submitted with a differential diagnosis that includes idiopathic sclerosing pseudotumor, it is incumbent upon the pathologist to rule out other diagnostic possibilities before designating the lesion as idiopathic. In order to survey the range of diagnoses for such specimens, we searched over a 10-year period for specimens submitted to the University of Colorado pathology department which either clinically or pathologically raised the possibility of idiopathic sclerosing ps...

Paget's disease if Nipple- Review
Clinical: Approximately 1%–3% of women with adenocarcinoma of the breast have Paget disease. Clinically-Paget disease has common dermatitis-like appearance, as originally described in 1874, when Sir James Paget recorded that such lesions may resemble “ordinary chronic eczema” or present as nipple erosion or ulceration. Paget disease often has a deceptively banal clinical morphology but should lead the list of differential diagnoses when evaluating unilateral lesions of the nipple–areola complex in adults. Paget disease presenting with nipple erosion.  Most women with the histopathologic finding o...
