超聲診斷男性乳腺發(fā)育癥及其某些發(fā)病規(guī)律探討
[Abstract]:Research background and purpose:
In recent years, women's breast disease has been paid more and more attention. With the popularization of health knowledge and the enhancement of health awareness, the prevention and treatment of female breast cancer has been widely paid attention. In comparison, male breast disease is often ignored, and male mammary gland development is the most common male breast disease.
Male mammary gland development refers to the benign thickening of the gland tissue of the male mammary gland, which can occur at any age. According to the epidemiological report, the prevalence rate in the male population of foreign men can reach 32%-65%. ultrasonography in the diagnosis of male mammary gland development. More scattered, and there may be differences in breast disease between domestic and western white men, we need our own data.
The purpose of this study is to explore the important clinical value of ultrasound diagnosis and follow-up monitoring of male mammary gland development, and to explore and explore the age of the disease, the year and the distribution of single side and bilateral distribution, and to analyze the data of male mammary gland development by ultrasound.
Method:
178 male patients, aged 3-98 years and 36.8+21.7 years old, were selected in our hospital in January 2005 -2013 December. Among them, 145 cases of male mammary gland development, 3-98 years old and average 35.8 + 21.1 years old, were diagnosed by ultrasound. The ultrasonographic features of 145 male mammary gland development confirmed by pathology or clinical diagnosis were analyzed and summarized. The ultrasonographic diagnosis was compared with pathology and follow-up results.
The basic situation of all the data, the ultrasound examination and the results entered the computer excel file, sorting out the statistics. All male breast development patients according to the age of 19 years, 20-39 years old, 40-59, 60-79, 80 years of 5 groups; less than 30 years and 30 years of two groups; 20-39 years and non age group two; according to the year of examination, 2006, 2006, 2005, 2006. In 2007, 2008, 2008, 2009, 2010, 2011, 2012, and 2013, the 9 groups were analyzed with SPSS19.0 software. The distribution of patients in different age groups and different examination years was analyzed by spear test. The difference was statistically significant with the difference of P0.05.
Result:
Of the 145 male patients with mammary gland development, 95 were unilateral (95/145,65.52%), of which 57 were developed in the left side of the breast, 38 in the right, and 50 in the bilateral (1 of the left lesions developed to bilateral). The ultrasonographic map showed the thickening of the glands of the breast in varying degrees, the length of the diameter of about 2.1 to 6.6cm, the average length of 3.38+0.92cm, and the thickness of about 0.50 to 2.90. Cm, average 0.78+0.30cm.
Characteristics of ultrasonic image of male mammary gland development: below the nipple, the echo of thickened mammary gland tissue around the corola can be seen around the mammary gland. It can be hypoechoic or slightly hyperechoic or honeycomb echo, the boundary is clear, no capsule, and the boundary between the anterior subcutaneous adipose tissue and the posterior pectoralis major muscle is visible, the internal echo is even or less homogeneous, and there is no obvious echo calcification. Color Doppler flow imaging (CDFI) showed that the blood flow signals in and around the glands were not abundant.
In this study, we analyzed the ultrasonographic features of 145 cases of male mammary gland development, compared the pathological and follow-up results, and analyzed the age of the disease, examined the year, and the distribution of the single bilateral. The conclusions are as follows:
1. ultrasound is the first choice for the diagnosis and differential diagnosis of gynecomastia.
2. ultrasound has the advantage of follow-up and evaluation of male breast development.
3. for the first time, male patients with breast development were found in the age group of 20~39.
4. the first study found that the incidence of gynecomastia increased in recent years, the most in 2013.
5. in this group, unilateral breast development is the most common (95/145,65.52%).
