[Skin lesions after injection abuse. Chronic changes caused by ketobemidone (Ketogan)]. / Hudskader efter injektionsmisbrug. Kroniske forandringer forårsaget af ketobemidon (Ketogan).

Local complications of repeated injections of pentazocine are known among drug abusers. We hereby describe similar reactions in three patients who for several years had abused the opioid analgetic ketobemidone for chronic pain after abdominal surgery, and in six drug addicts who regularly injected ketobemidone tablets dissolved in water. In all nine patients an impressive clinical picture with disfiguring woody fibrosis and multiple irregular ulcers and scars surrounded by hyperpigmentation on the upper and lower extremities was seen. The skin lesions had been mistaken for aggressive forms of panniculitis, pyoderma gangrenosum or selfmutilation. Following direct questioning most patients admitted self-administration of the drug to the affected areas. The patients showed an apparent indifference about their extensive disabling skin disease, and no obvious complaints of pain, contrary to what might be expected from the pronounced tissue destruction and inflammation at the injection sites.

[Hemangioendothelial sarcoma of the thyroid]. / Haemangioendoteliosarkom i glandula thyreoidea.

Haemangioendothelial sarcoma in the thyroid gland is a very rare disease in regions where goitre is not endemic. The case history of a man aged 65 years who had previously enjoyed good health who developed this disease is reviewed as regards diagnosis, treatment and course of the condition and this emphasizes the poor prognosis in this condition.
