8500/3 Duct cell carcinoma

Pancreas

/span> malignant tumour derived from ductal epithelia. Microscopically, randomly arranged epithelial elements are seen. When large sheets of malignant cells are present, necrosis may be seen. With adequate tissue sampling, in situ carcinoma can be demonstrated in association with the infiltrating carcinoma.

Infiltrating duct carcinoma of the pancreas
The epidemiological study of pancreatic carcinomas is complicated by significant geographical and temporal variations in the sensitivity and specificity of clinical diagnosis and in the proportion of cases that are histologically verified. The best-known risk factor for pancreatic cancer is tobacco smoking, but nutritional and dietary factors such as obesity, low physical activity, low intake of vegetables and fruits, as well as preexisting conditions such as chronic pancreatitis, diabetes mellitus and patients with gastrectomy have been reported. Ductal adenocarcinoma is fatal in almost all cases 1

Breast
ICD-O-3 topography code: C50
ICD10: C50
           

Invasive breast carcinoma of no special type (NST), commonly known as ductal carcinoma NST, comprises the largest group of invasive breast cancers. It is not an easily defined entity as it represents the heterogeneous group of tumours that fail to exhibit sufficient characteristics to achieve classification as a specific histological type, such as lobular or tubular carcinoma.



Lip, Oral Cavity and Oropharynx
ICD-O-3 topography code: C00-C06, C09-C10, C14
ICD10: C00-C06, C09-C10, C14
           

A malignant tumour derived from ductal epithelia. Microscopically, randomly arranged epithelial elements are seen. When large sheets of malignant cells are present, necrosis may be seen. With adequate tissue sampling, in situ carcinoma can be demonstrated in association with the infiltrating carcinoma.



Prostate gland
ICD-O-3 topography code: C61
ICD10: C61
           

A malignant tumour derived from ductal epithelia. Microscopically, randomly arranged epithelial elements are seen. When large sheets of malignant cells are present, necrosis may be seen. With adequate tissue sampling, in situ carcinoma can be demonstrated in association with the infiltrating carcinoma.



Salivary glands
ICD-O-3 topography code: C07-C08
ICD10: C07-C08
           

A malignant tumour derived from ductal epithelia. Microscopically, randomly arranged epithelial elements are seen. When large sheets of malignant cells are present, necrosis may be seen. With adequate tissue sampling, in situ carcinoma can be demonstrated in association with the infiltrating carcinoma.



Vulva
ICD-O-3 topography code: C51
ICD10: C51
           

In the vulva, carcinoma resembling invasive duct carcinoma of the breast arise from specialized anogenital mammary-like glands typically in or adjacent to the intralabial sulcus
