Other findings may include adenomatous hyperplasia of the thyroid and parathyroid glands, multinodular hyperplasia of the adrenal cortices, multifocal or disseminated nodular hyperplasia of the pancreas with ductal fibrosis, lymphocytic-plasmacytic infiltration, hyalinisation of the islets, and amyloid deposition.

Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases. Microscopically, a lobular proliferation of bland-appearing hepatocytes with a bile ductular proliferation and malformed vessels within the fibrous scar is the most common pattern.
Focal nodular hyperplasia (FNH) is the second most common benign tumor of the liver. [2] FNH is found in 0.2%– 0.3% of adults worldwide. [2] FNH is more common in females (10:1 female to male ratio) except in Japan and China, in which there is a more equal prevalence of cases between females and males. [2]
Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).
Hepatic adenomas may be misidentified as focal nodular hyperplasia in diagnostic imaging, though this condition is rare. However, hepatic adenomas in GSD I uniquely involve diffuse Mallory hyaline deposition, which is otherwise commonly observed in focal nodular hyperplasia. Unlike common hepatic adenomas related to oral contraception ...
Desmoplastic small-round-cell tumor (DSRCT) is an aggressive and rare cancer that primarily occurs as masses in the abdomen. [4] Other areas affected may include the lymph nodes, the lining of the abdomen, diaphragm, spleen, liver, chest wall, skull, spinal cord, large intestine, small intestine, bladder, brain, lungs, testicles, ovaries, and the pelvis.
Genetics may play a part in the risk factor. [2] Certain cat breeds may have a predisposition. [4] Dogs suffering from diabetes mellitus, Cushing's disease (hyperadrenocorticism), hypothyroidism, and epilepsy have been reported to have an increased risk but no there is a lack of evidence to support a link between the conditions and pancreatitis ...
It is a rare disease in dogs, with cat and horse infections predominating in veterinary medicine. The disease in dogs is usually nodular skin lesions of the head and trunk. [22] Aspergillosis* is a fungal disease that in dogs is caused primarily by Aspergillus fumigatus. Infection is usually in the nasal cavity.
