Intraductal papilloma diagnostic criteria
- Because the clinical manifestations and morphological characteristics of the two are very similar, the differential diagnosis of the two is very difficult. It is generally believed that the discharge of papilloma in the duct of the breast can be bloody, or serous or serous; and papillary cancer is more common with bloody, and it is mostly unilateral and single hole. Most of the papilloma tumors are located in the areola area, and the texture is soft. The mass is generally no larger than 1 cm, and the ipsilateral axillary lymph nodes are not enlarged. Most of the papilloma tumors are located outside the areola area. The texture is hard, the surface is not smooth, and the mobility is poor. , Easy to adhere to the skin, the mass is generally greater than 1cm, ipsilateral axillary can be seen enlarged lymph nodes. A ductal angiogram of the breast showed a sudden interruption of the catheter with a smooth cup-shaped stump. The proximal catheter showed a significant dilation, sometimes a round or oval filling defect, and the catheter was soft and smooth, most of which were papillomas inside the catheter. The stump is irregular, the proximal catheter is slightly dilated, distorted, arranged disorderly, filling defect or complete obstruction, the catheter loses its natural softness and becomes stiff, etc., it is mostly intraductal cancer. A papillary carcinoma of the discharge smear cytology can find cancer cells. The final diagnosis is based on pathological diagnosis, and paraffin sections should be performed to avoid false negative or false positive results due to the limitations of frozen sections.
Clinical manifestations of intraductal papilloma
- Intraductal papilloma of the breast and duct dilatation syndrome: The main symptoms of intraductal papilloma and duct expansion syndrome can be nipple discharge, but duct expansion syndrome is often accompanied by congenital nipple depression, overflow The fluid is mostly bilaterally porous, and can be watery, milky, serous, purulent, or bloody; papilloma and duct dilatation syndrome can be seen under the areola, but the latter often have a larger mass than the former It is large, and the shape of the mass is irregular, and the texture is hard and tough. It can adhere to the skin. Redness, swelling and pain often occur. Later, ulceration and pus may occur. Catheter dilatation syndrome can also be seen in the affected axillary lymph nodes, tenderness. Catheterization of the mammary ducts shows that the catheter is abruptly interrupted, and those with regular filling defects are mostly papilloma; if the larger catheter is significantly dilated, the thickness of the catheter is uneven, and the normal dendritic shape is lost, the catheter expansion syndrome . If necessary, needle aspiration cytology or biopsy of the mass can be performed.
