As a whole body infection, syphilis, even in early stages of development affects many organs and systems. In late forms of syphilis, including those with tertiary syphilis, may be seen as a gummy processes in various internal organs, and diseases that can be attributed both to a truly visceral syphilis.
From the internal organs are mainly affected the cardiovascular system and liver. Syphilitic myocarditis secondary and especially tertiary period of syphilis is characterized by shortness of breath, fatigue,
general weakness, cardiac arrhythmias, muted tones of the heart and extending its borders, especially to the left. Syphilitic myocarditis has no specific clinical features and does not differ from other causes myocarditis. Diagnosing of it is carried out on the basis of other clinical and laboratory signs of syphilis, particularly aortitis, which often accompanies myocarditis.
Syphilitic aortitis - the most common manifestation of visceral syphilis. Major changes occur in the middle of the shell of the aorta, due to what there are talking about mezaortite, which leads to compaction of the aortic wall and expand it in the ascending part (the last for quite pathognomonic of syphilitic lesions of the aorta) . If the normal ascending aorta is 3-3.5 cm, with mezaortite it reaches 5-6 cm, and often has a flask-shaped expansion.
Syphilitic aortitis can lead to a dangerous complication - the emergence of an aortic aneurysm, a gap which, in 1/3-1/4 of cases is instantly fatal.
Liver damage in the tertiary period of syphilis occurs in 2-4% of cases of visceral syphilis. There are focal gummy, gummy miliary or diffuse infiltrative, epithelial and chronic syphilitic hepatitis.
Other internal organs (kidneys, lungs, stomach, intestines, etc.) are currently affected with tertiary syphilis is extremely rare (collectively constitute no more than 1-1.5% of the specific pathology of visceral Tertiary).
