Pinemoth caterpillar disease.
Pinemoth caterpillar disease is a well-recognised disorder which occurs in South-Eastern China and is due to contact with the cocoons or larvae of the pinemoth (Dendrolimus punctatus). Generalised symptoms, which may be noted within two weeks of contact, consist of pyrexia, anorexia, malaise, rigors, headache, or dizziness. Localised abnormalities include dermatologic changes, skin nodules, and arthritis. The arthritis is usually monoarticular and most frequently involves the knee, ankle, and wrist. The radiologic findings consist of periarticular swelling, osteoporosis, erosions, or periosteal reaction in the acute phase and osseous sclerosis, joint deformity, persistent soft tissue swelling, or premature fusion of ossification centers in the chronic stages.
