A Jungian Approach to Individual Neuropathological Specimens
I was readingThe Undiscovered Self (1958) by Carl Jung today, and noted that Jung ' s description of individual patients could also be applied to individual tumors:" The statistical method shows the facts in the light of the ideal average but does not give us a picture of their empirical reality.... The distinctive thing about real facts, however, is their individuality.... There is and can be no self-knowledge based on theoretical assumptions, for the object of this knowledge is an individual - a relative exception and an irregular phenomenon. Hence, it is not the universal and the regular that characterize the individual...

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...

cIMPACT-NOW Update 4: diffuse gliomas characterized by MYB, MYBL1, or FGFR1 alterations or BRAFV600E mutation
This cIMPACT-NOW update was published this month:Summary:cIMPACT (Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy) has reviewed the status of WHO grade II IDH-wt/H3-wt diffuse gliomas, focusing on those with a BRAFV600E mutation, FGFR1 alteration, or a MYB or MYBL1 rearrangement, and recommends the use of an integrated diagnosis to combine their histologic and genetic features. The consortium ecommends the use of an integrated diagnosis to combine their histologic and genetic features, as suggested in the following:Diffuse glioma, MYB...

PML in a patient with idiopathic CD4 lymphopenia
My last post prompted the inimitableDr. Murat Gokden to write to me about an interesting case he published in 2015 of a 33-year-old man who with idiopathic CD4 lymphopenia (ICL) who was ultimately diagnosed with progressive multifocal leukoencephalopathy (PML).Image from Dr. Gikden ' s paper: A and B are MRI FLAIR images showing hyperintense areas with gyral swelling and sulcal effacement (curved arrows). Image C depicts MR spectroscopy with abnormally elevated choline peak. Image D shows multifocal punctate enhancement in white matter.Murat Gokden, MD (Source: neuropathology blog)

Progressive Multifocal Leukoencephalopathy in patients without obvious immunosuppression
I recently received a case in consultation which turned out to be progressive multifocal leukoencephalopathy (PML). Reading the clinical history, it was not entirely clear what predisposed the patient to PML. It wasn ' t clear, that is, until my mentor (the illustrious BK DeMasters) to a nine-year-old paper by Sarah Gheuens, Gerald Pierone, Patrick Peeters, and Igor J. Koralnik entitled Progressive Multifocal Leukoencephalopathy in individuals with minimal or occult immunosuppression (J Neurol Neurosurg Psychiatry 2010;81:247-254). In this series, hepatic cirrhosis -- which was what my patient had -- was among the more com...
