H&E stain. Acinar cell carcinoma of the pancreas, also acinar cell carcinoma, is a rare malignant exocrine tumour of the pancreas. It represents 5% of all exocrine tumours of the pancreas, making it the second most common type of pancreatic cancer. [ 1 ] It is abbreviated ACC. It typically has a guarded prognosis.
Acinar adenocarcinoma of the lung is a highly lethal disease. Overall, the five-year survival rates approximate 16% to 22%. Generally, survival is better in all stages for patients with the acinar (or papillary) pattern than it is in patients with the solid pattern, but considerably worse than those with the bronchioloalveolar pattern.
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
Pancreatic cancer can be treated with surgery, radiotherapy, chemotherapy, palliative care, or a combination of these. [1] Treatment options are partly based on the cancer stage. [1] Surgery is the only treatment that can cure pancreatic adenocarcinoma, [12] and may also be done to improve quality of life without the potential for cure.
The metaplastic epithelial is at the junction (center of image) and has an intensely eosinophilic (bright pink) cytoplasm. H&E stain. Specialty. Oncology. Pancreatic acinar metaplasia (PAM) is a common incidental histopathologic finding present in approximately 20-25% of patients undergoing an esophagogastroduodenoscopy. [1][2]
Resected pancreatoblastomas can be quite large, ranging from 2 centimeters to 20 centimeters in size (1 to 8 inches). They are typically solid, soft masses. Under the microscope, at least two cell types are seen: cells with “acinar” differentiation, and cells forming small “squamoid” nests. The cells with acinar differentiation have ...
A subtype of adenocarcinoma, the bronchioloalveolar carcinoma, is more common in female never-smokers, and may have a better long-term survival. [13] This cancer usually is seen peripherally in the lungs, as opposed to small cell lung cancer and squamous cell lung cancer, which both tend to be more centrally located. [14] [15]
0.6% (cats) 0.8% dogs. Pancreatitis is a common condition in cats and dogs. Pancreatitis is inflammation of the pancreas that can occur in two very different forms. Acute pancreatitis [ 2 ] is sudden, while chronic pancreatitis is characterized by recurring or persistent form of pancreatic inflammation. Cases of both can be considered mild or ...
