Abstract

In 2012, a novel canine Dirofilaria species, D. hongkongensis was identified in Hong Kong that caused human diseases and subsequently reported in an Austrian traveller returning from the Indian subcontinent. Here we present a case of human infection by D. hongkongensis manifested as recurrent shoulder mass. Diagnosis was achieved by cox1 gene sequencing of the excised specimen. The case illustrated that parasitic infection represents an important differential diagnosis for musculoskeletal lesions.

Keywords: Dirofilaria hongkongensis; Human; Recurrent; Sequencing; Subcutaneous; Zoonosis.
