A very important part of being a pathologist is giving real-time diagnosis of biopsies. In this case, a liver biopsy arrived and they wanted to know if it was cancer. He was able to tell them withing 10 minutes the answer. Here, he's using a disection microscope to quickly choose a set of cells to put on a slide.
The patient had been ingesting iron pills but there was no known history of aspiration. This is not unusual. The diagnosis of aspiration is often initially made by microscopic examination of lung tissue by pathologists. Aspiration often goes unrecognized by both clinicians and pathologists. In a review of 59 surgical lung specimens exhibiting aspiration pneumonia, aspiration was suspected clinically in only 4/45 (9%) of cases in which a clinical impression or differential diagnosis was provided (PMID 17460460). In a report of one hundred consecutive granulomas in a pulmonary pathology consultation practice, it was determined that aspiration pneumonia was the condition most commonly unrecognized by the referring pathologist (PMID 20871220).

U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) team led by Research Leader and Plant Pathologist Timothy Gottwald (now retired) at the U.S. Horticultural Research Laboratory in Fort Pierce, FL, answered the call from the Farm Bureau of Ventura County, California, who needed a fast and effective way to detect huanglongbing—also known as HLB or citrus greening that has no cure for the tree. Detection dog that could sniff and detect the presence of the virus in individual trees in an orchard.
Testing started in California in 2017 and deployment by F1K9 began in 2019. They developed and delivered the first-ever team of HLB detection dogs”
Their 99 percent accuracy and the cost-efficient operation proved to be a success. For more information, go to tellus.ars.usda.gov/stories/articles/barking-up-the-right-tree-canines-detect-hlb/.
The canine-detection method was validated in blind tests by USDA ARS in collaboration with the California Department of Food and Agriculture, with results published in 2020.

Forest pathologists Josh Bronson and Ellen Goheen (Southwest Oregon Service Center) collecting whitebark pine samples that died from an unknown cause to test for Phytophthora. Dorena Genetic Resouce Center. Cottage Grove, Oregon.
A note on the initial test results from Josh Bronson, via Richard Sniezko:
“I tested some roots from the WBP that we collected samples from on Friday. All tested positive in our Phytophthora ELISA kits (see attached). This may or may not be the cause of death, it only indicates presence of antibodies. Many of them were resin-soaked and stained at the root collar. A few of the smaller seedlings from frame 76,113 also appeared to have sunken stem cankers on the main stem most likely caused by our favorite shoot blight. I will continue to investigate, I would suggest you get in touch with the plant ID clinic at OSU to get a species on the Phytophthora.”
Additional note from Richard Sniezko: "This might be (???) the first documentation (?) of Phytophthora mortality in whitebark."

Dogs can be trained to detect specific bacterial or viral pathogens in any part of a plant with greater than 99% accuracy, significantly faster than laboratory tests, and before visible symptoms are obvious. Conventional analysis typically uses only one leaf from a plant. At the early stages of infection, before the disease spreads throughout the plant, a healthy leaf may be taken from an infected plant resulting in a negative laboratory test. In contrast, dogs sample the entire plant while walking by and sniffing it.

Summary: Maud Slye (1879-1954) was a pathologist and noted cancer researcher at the University of Chicago. A descendant of John Alden of the Plymouth Colony, Slye had attended the University of Chicago in 1896 with little money but, as her New York Times obituary wrote, "with the urge to become a scientist." She eventually earned a degree from Brown University, taught school for a while, and then returned to Chicago for graduate work, beginning a research and teaching career at the university that ended with her retirement in 1944. Well-known for arguing in 1926 that "heredity of cancer and non-cancer uniformly follows a perfect Mendelian pattern" ("Cancer Hereditary, Chicago Woman Shows," Science News-Letter, March 20, 1926), Slye was a tireless researcher and a prolific poet. Two volumes of her verses appeared during the 1930s, including the 450-page Songs and Solaces

My name is Cindy and my rare disease story starts in August 2011, the day after my 47th birthday. I underwent an emergency appendectomy that seemed to be a routine procedure. However, three days later, I would learn that lurking within my appendix was a malignant tumor. Nobody can ever be prepared to hear those devastating words … cancer. I had never heard of appendix cancer before. The pathologist and the surgeon had never seen a case before. As the days and weeks went by, I started to realize just how rare this cancer was. That was frustrating for me; but even more so, it was very frightening as I felt so alone.
My formal diagnosis was Pseudomyxoma Peritonei (pronounced sue-doh-mix-oh-muh payr-ih-toh-nee-i) or abbreviated as PMP. This rare cancer usually starts as a small growth in the appendix. The tumor will eventually break through the appendix wall creating a condition characterized by spreading of tumor cells into the peritoneum (abdominal cavity) via the jelly-like mucin the tumors produce. Although estimates vary, PMP was once thought to be diagnosed in about 1000 people world-wide each year. In other words, the lifetime odds of being diagnosed with PMP are about 1 in 1 million.
I was fortunate in that my PMP was diagnosed following a rapid-onset appendicitis in which my appendix had not ruptured. However, the tumor had grown to within 1 mm of coming through the wall of the appendix. Not enough to be considered a clean margin. I was so confused and troubled by talk of additional surgeries and treatments by doctors and surgeons that had never dealt with this cancer before. After doing my own research on the internet, I came across information and treatment options with a limited number of “specialists” here in the US. By God’s grace, I had two of those doctor’s within an hours drive of where I live.
After one visit with a surgical oncologist at the University of Nebraska Medical Center (UNMC), I knew God had put me in the right place. I underwent a 7 hour surgery at the end of November 2011. The exploratory part of the surgery resulted in no visual evidence of cancer spread within the peritoneal cavity! The diagnostic part of the surgery (right hemicolectomy) resulted in twenty-eight cancer-free lymph nodes!
Though I am only three months out from my surgery and my journey continues, I am hopeful for my future. Those two faces in this picture with me are my children. They are the reason I live for. They are the reason I have shared my story here … to help raise awareness of PMP. While my faith, family and friends have gotten me through thus far; it will be through improved awareness, more research, improved diagnostic methods, and more funding that will help me and many others inflicted by an “orphan” disease truly have a brighter tomorrow.

The pathologists investigate when a military helicopter crashes into a refugee detention center. Harry and Nikki actually witnessed the crash and were first on the scene but the case is complex since the center was Ministry of Defense property leased to the Home Office. The team is shocked at the conditions they find in the center and Harry, who has a close friend in the RAF, is shaken when a government Minister attributes the accident to pilot error.

Sir James Paget, 1st Baronet (11 January 1814 – 30 December 1899) was an English surgeon and pathologist who is best remembered for Paget's disease and who is considered, together with Rudolf Virchow, as one of the founders of scientific medical pathology. His famous works included Lectures on Tumours (1851) and Lectures on Surgical Pathology (1853). While most people recall Paget's disease refers to bone, two other diseases were also named after him: Paget's disease of the nipple (a form of intraductal breast cancer spreading into the skin around the nipple), and extramammary Paget's disease. Also named for him is Paget's abscess.
As a pathologist, a highlight of my trip was to visit one of the early sites of academic anatomy study. The body was placed on the marble slab and was dissected by the workers (called dieners), while the professor proclaimed the findings from the pulpit. Students observed from the benches. The statues at the front are the "Spellati," the "skinned ones"--statues of people with the skin removed, to highlight the musculature.

A sweet potato plant with galling, the abnormal enlargement or swelling of or on the root of a plant, is seen here at the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS), U.S. Vegetable Laboratory in Charleston, South Carolina, on January 28, 2021.
Research Plant Pathologist-Nematologist William Rutter, Ph.D., works here to develop tools to manage and mitigate the damage caused by the Meloidogyne enterolobii (the guava root-knot nematode), and other root-knot nematode species.
Nematodes are small microscopic roundworms in the soil.
These specific nematodes only appeared in the United States within the last 20 years and they've slowly been spreading across the southeastern states causing damage in sweet potato as well as several other crops.
This research will provide resources to develop germplasm that will help breeders develop new crop varieties that are resistant to the nematode as well as management practices that will help farmers directly manage the nematode and stop its spread in the field.
Part of the work includes the imaging of infected plants with a spectral imager that reveals signatures that are not visible to the naked eye. The hope is to score plants for their susceptibility to this nematode.
Root-knot nematodes in general and particularly Meloidogyne enterolobii can infect the majority of cultivated plants in the U.S. They're currently causing a lot of damage in sweet potato in the Carolinas, but they also infect other vegetable crops such as pepper, cucumber, watermelon, as well as soybean and cotton. Root-knot nematodes cause billions of dollars of damage each year for the U.S. and farmers globally.

The portrayed: Robert Langerhans (1859-1904) was assistant of Rudolf Virchow and later professor of Pathology in Berlin (at Moabit Hospital). In 1896, his son Ernst died shortly after being injected (by his father) with a prophylactic dose of anti-diphtheria serum. The father, claimed, in the obituary notice, that his son had been poisoned by Behring's anti-diphtheria serum, which generated a scandal (see more at
www.ncbi.nlm.nih.gov/pubmed/17144617 ).
Robert Langerhans was the step-brother of Paul Langerhans who discovered the pancreatic structures called the Langerhans islets (that produce Insulin)

Jim Hadfield retirement luncheon. Wenatchee Service Center. Forestry Sciences Lab, Wenatchee, Washington.
From Jim's 2011 Western International Forest Disease Work Conference (WIFDWC) Keynote Address:
"In 1971 I accepted a transfer and promotion to the Pacific Northwest Region in Portland, Oregon. Dave Johnson had arrived about one month before me. Dave Graham was the staff director. Walt Thies joined the staff in 1973. Over the years many forest pathologists joined this staff, including Don and Ellen Goheen, Greg Filip, Craig Schmitt, Paul Hessburg, Bob Harvey, Boris Tkacz, Sally Campbell, Susan Frankel, Alan Kanaskie and my apologies to others I have overlooked. We provided forest pathology advice to all National Forests and other federal and tribal lands in Washington and Oregon from Portland. I took a bit of a break from forest pathology from 1988 to 1993 when I more-or-less became a killer of western spruce budworms and Douglas-fir tussock moths. In 1994 I resumed being a forest pathologist when I moved to Wenatchee, WA, where I am thoroughly entrenched.
