Acute Appendicitis
Acute Appendicitis

Acute appendicitis is inflammation of the appendix, a small pouch that hangs off of the beginning of the large intestine. Thus usually occurs due to an obstruction and can become infected.

In this image, the various layers of the appendix can be seen. The purplish haze seen through the appendiceal layers is evidence of the inflammatory cells.

Cholangiocarcinoma
Cholangiocarcinoma

Cholangiocarcinoma is a cancer of the biliary tree; a system of ducts that carries bile from the liver to the small intestine where it is used to aid in digestion.

In image 2, the ducts, which appear as large circular structures, are disorganized with irregular lumens. The nuclei of their cells, which appear as smaller dark purple structures, show variation in shape and size when in normal ducts they should be the same size and shape. In image 3, the ducts are again disorganized. In this image, mucinous secretions are more evident than in image 2.

Congo Red Positive Amyloid Deposits in the GI Tract
Congo Red Positive Amyloid Deposits in the GI Tract

Amyloid deposits are insoluble collections of misfolded proteins. These misfolded proteins can be involved in a number of disease processes including amyloidosis, Alzheimer’s disease, rheumatoid arthritis and many more.

In this image, the amyloid deposits are highlighted by a special stain called Congo Red which gives them a bright red-orange color under standard microscopy. Under polarized light the amyloid will have an apple-green color.

BILLING INFORMATION

Why did I get a bill for pathology services? Pathologists practice independently from your primary care physician or specialist. If you have received a bill from Michigan Diagnostic Pathologists, this is because your physician has requested us to perform a diagnostic test on either a blood or tissue specimen from you. Even if you do not physically visit our laboratory, we may still perform a test on the samples sent to us.

When our services are requested by your physician, we track the specimens and the tests which were performed on them. We then provide this information to our billing company, a specialist who sends the bill to your insurance company. In most cases, this bill will be separate from the bill submitted to your insurance company by your physician. Our bill will generally not be covered by any co-pay made at the time you saw your doctor.

If you have questions about a bill, feel free to contact our billing company and reference Michigan Diagnostic Pathologists. All billing questions are handled in strict confidence. For general questions about billing, please visit the "Contact Us" page.
