Abstract:
We report a case of ulcerative lupus vulgaris (LV) in a unique site, which facilitated the detection of internal organ tuberculosis (TB). A 68-year-old Japanese man presented with a reddish ulcerated painless lesion on his right wrist that had initially appeared 4 weeks earlier as a nontender nodule. There was no recent history of fever, weight loss, or cough. The results of tissue culture, PCR, and contrast-enhanced chest computed tomography were consistent with the diagnosis of ulcerative LV with underlying pulmonary TB and tuberculous lymphadenitis. The patient was started on anti-TB therapy. After 1 month of therapy, epithelialization of the ulcer was noted.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
