Tuberculoid Leprosy with External Jugular Vein Thrombosis: A Case Report and Literature Review.

Unlabelled: Thrombotic disease represents a rare manifestation of leprosy. In this study, we report the case of an external jugular vein thrombosis associated with tuberculoid leprosy in a 23-year-old male patient. The patient presented with a 3-month history of painful cord-like swelling on the left side of the neck and a nearly 3-week history of skin lesions on the left cheek and right leg. Physical examination revealed cord-like, tender swelling on the left lateral aspect of the neck overlying the sternocleidomastoid muscle, and a hypopigmented, hypoaesthetic 6×7 cm lesion with an irregular margin on the left cheek. A Doppler ultrasound examination of the jugular vein showed thrombosis of the left external jugular vein. Three-dimensional reconstruction of the computed tomography scan showed the enlarged and enhanced left external jugular vein, as well as 1 of its tributaries, and the thickened skin patch. A skin punch biopsy from the left cheek lesion revealed granulomatous inflammation with occasional peri-adnexal granulomas, consistent with the clinical impression of tuberculoid leprosy. A diagnosis of leprosy with external jugular vein thrombosis was established. Anticoagulation therapy was initiated, and the patient was referred to an infectious disease clinic for treatment with anti-leprosy medications.

Learning Points: Thickened cord-like neck swelling in leprosy can be vein thrombosis rather than a thickened nerve.Leprosy should be considered if a skin lesion is associated with thrombosis.The common causes of upper extremity DVT.
