Syphilis is less commonly seen in clinical practice. Hence, presenting features of primary, secondary, and tertiary forms of syphilis are not recalled during discussion. A case of syphilitic aneurysm observed in a 54-year-old male is presented to create awareness of this condition among healthcare professionals and stress importance of this entity in the differential diagnosis and treatment of mass in the chest wall.

| Introduction|| |
Syphilis, a sexually-transmitted disease caused by the spirochete Treponema pallidum continues to affect both developed and developing world. World Health Organization in 2008 estimated it to be 10.6 million new cases per year.  Primary and secondary lesions resolve even without treatment, and the infection enters a "latent" stage; it may also progress, resulting in tertiary manifestations including neurosyphilis, cardiovascular diseases, and gumma. 
Herein, we present a case of 57-year-old male, presenting with pulsatile chest wall mass as the only manifestation of tertiary syphilis in order to increase awareness and stress, the importance of this entity amongst healthcare professionals on rare presentations of less common disease.
| Case report|| |
A 57-year-old normotensive and euglycemic male truck driver presented to primary care physician with a complaint of swelling on the right upper part of anterior chest. The patient was referred to our tertiary care center for incision and drainage of the swelling-presumably an abscess. On presentation to us, we confirmed the same complaint; the swelling was insidious in onset and progressively increased in size over a period of 4 months. It was associated with a continuous, dull-aching chest pain of moderate intensity. There was no history of fever, weight loss, anorexia, neck pain, or any concurrent medications or herbal agents. Systemic examination was essentially normal with stable hemodynamics without features of heart failure or valvular heart disease. Local examination revealed an 8 × 6 cm mass on the right anterior chest wall besides the sternum. It was painful, pulsatile, non-reducible, fixed hemispherical swelling with mild hypopigmentation on the overlying skin, without any evidence of local inflammation or compression of surrounding structures [Figure 1]. Transillumination test was negative and there was no impulse on coughing.

His hematological, metabolic profile, and electrocardiogram (ECG) were within normal limits. Posteroanterior chest X-ray revealed a widened mediastinum of 10.3 cm with a mediastinal/chest width ratio of 0.49. Cardiac silhouette, pulmonary vascularity, and lung fields appeared normal [Figure 2]. His Mantoux test and human immunodeficiency virus (HIV) screening were negative. Transthoracic echocardiography revealed normal left ventricular function and dimensions with a dilated ascending aorta with a root diameter of 5.2 cm at the sinotubular junction. The aortic valve was normal without any regurgitation. On further questioning, patient gave history of contact with multiple sexual partners as a teenager with a diagnosis of primary syphilis 35 years ago, for which he was not compliant with treatment.
Tertiary syphilis was suspected, on the basis of previous history of sexual promiscuity which was confirmed with a reactive rapid plasma regain (RPR) (1:64) along with a positive fluorescent treponemal antibody adsorption (FTA-ABS) test (1:800). Cardiac catheterization demonstrated normal coronary artery anatomy with normal pulmonary artery (PA) pressure. He had no other neurological or dermatological manifestations of tertiary syphilis. An aortogram revealed a massive fusiform ascending aortic aneurysm measuring 8.8 cm (88 mm) of maximum diameter from the origin of the brachiocephalic artery with normal diameter across the descending thoracic and abdominal aorta and no flow-limiting obstruction [Figure 3], which is the classical site for syphilitic lesion. He was treated with penicillin and probenecid for 2 weeks. The size and etiology of the aneurysm warrants surgical management, but the patient refused surgical procedure and biopsy of the lesion. On summary, we have confirmed the diagnosis as tertiary syphilis induced aortic aneurysm based on untreated primary syphilis, serology titer, and classic site of the lesion.

| Discussion|| |
Tertiary cardiovascular syphilis usually manifests with a latency of 10-40 years after the initial insult. ,, The spirochete invade the aortic wall, causing an inflammation 'aortitis' - endarteritis obliterans resulting in necrosis of elastic and connective tissue of tunica media. , The scarred and weakened aortic wall, thereby progresses into vascular complications. Aortic aneurysm is the most common complication and usually affects the tubular portion of ascending aorta (50%) (due to tropism of T. pallidum to the rich lymphatic system). Followed in descending order by aortic arch (35%), descending aorta (15%), and abdominal aorta rarely.  Severe complications like valvular disease and myocardial ischemia are more common in Indian population.  Most common initial symptom is chest pain due to aneurysmal dilatation,  however, other symptoms like angina, dyspnea, and rupture occur frequently depends on the site and extent of the lesion.
Serologically,  Treponema-specific tests like FTA-ABS are more specific compared to RPR or Venereal Disease Research laboratory (VDRL) tests. Consensus statement  advises surgical repair of any ascending aorta of aortic root aneurysms greater than 5.5 cm in diameter. Even after explaining the risks involved and counseling, the patient did not want to undergo surgical repair. Long-acting penicillin for 2 weeks is the recommended treatment in tertiary syphilis.  Practicing doctor has to realize and explain the patient and family members on the progress of the disease despite antibiotic treatment, and the need for long-term follow-up.
| Conclusion|| |
This case of syphilitic aneurysm is presented not only to create awareness of rare presentations of less common disease among healthcare professionals. Also, this case highlights on the importance of never needling/draining/excising a mass without the essential investigations including imaging studies even if it looks like an 'abscess'.  Aneurysms of ascending aorta may present insidiously with very few signs and symptoms. Health policy makers have to utilize the media well to create awareness among high-risk group on the importance of barrier methods and the need for completing the treatment for early lesions.
