Guest Post: Fibrous Bodies Nicely Demonstrated in a Smear from a Somatotroph Pituitary Adenoma
Christian Davidson, MDDr. Christian Davidson, director of neuropathology at theRobert Wood Johnson University Hospital in New Jersey, provides today ' s blog post:A 30-year-old man presented with bitemporal hemianopsia and a 3.0 cm pituitary mass was discovered upon MRI. His IGF-1 was elevated to 900, but he had no signs of acromegaly. A smear of tissue sent for frozen section evaluation (see above below) revealed that most cells had round, eosinophilic, perinuclear inclusions suggestive of fibrous bodies (some examples are circled). Dot-like CAM5.2 immunostain (not shown) confirmed my smear-based diagnostic suspicion...

MKSAP: 64-year-old woman with an incidental pituitary adenoma
Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians. A 64-year-old woman is seen for follow-up evaluation.

She is otherwise healthy and takes no medications. She went through menopause at age 51. She has night sweats two to three times per month and occasional hot flushes. These have improved over the past decade and are not bothersome. She is not sexually active. She has never taken hormone replac...

Symptoms of Unknown Origin – The Prevalence of False Diagnosis of Disease
This study only raises the question, “How common is the error of assigning a false diagnosis of a disease?” The literature is surprisingly silent on the prevalence of false diagnoses. I can find only one dated study of the prevalence of false diagnoses in a population. In 1967, Berman and Stamm studied over 100 children in the Seattle school system that carried a diagnosis of heart disease. (2.) Rounding off the figures, only 20 percent were found to have heart disease on careful study. Eighty percent did not have heart disease. The most telling finding was the presence of severe psychological and physical disability i...

The Story of the Dying Doctor Who Saved a Patient’s Life
By TERRY BENNETT, MD I have mentioned that in the past, often at times of great duress in my life, often in the midst of cacophony, some window in time and space opens, if only for a moment, but the moment becomes a moment of grace, and, in that moment, an extraordinary medical feat has been granted to me. I have no explanation for any of this, I admit freely that I “hear voices”, voices that others do not hear. I cannot complain about a gift, this gift, weird as it may sound to others This year, while sick as a dog from the cancer chemotherapy I was receiving for the metastatic cancer that I had discovered in De...

An Introduction to IGF-1 in Aging
Of the many proteins and signaling pathways shown to influence the pace of aging, insulin-like growth factor 1 (IGF-1) is perhaps the most studied: The really fun thing about discussing signaling networks (the inputs that let cells make decisions based on their environment) in aging is the wide range of ways that these pathways exert their influence. They take inputs (nutrition, hormones, toxic molecules) and use their existing programming (epigenetic state) to make decisions. Components that control one process, such as regulating body size, can play roles in completely different processes. Today, I'll discuss an example...
