A case of dermal mucinosis and musculoskeletal symptoms simulating polymyositis as a presenting sign of hypothyroidism is presented. The patient presented muscle weakness and edema of the face including the eyelids. Laboratory examination revealed elevated creatinine phosphokinase, decreased free-T4, decreased free-T3, elevated TSH, positive anti-microsome antibody and positive anti-TSH receptor antibody. The skin biopsy specimen revealed swelling of the collagen bundles with the bundles splitting up into individual fibers, with some blue threads and granules of mucin interspersed. Alucian blue stain demonstrated vast amounts of mucin throughout the whole dermis, which was completely removed on incubation with Streptomyces hyaluronidase. The patient was diagnosed as having hypothyroidism due to Hashimoto's disease with possible polymyositis complications. After two months of thyroid hormone replacement therapy, she was euthyroidic and discharged. These results indicate that our case was a rare case of severe generalized myxoedema due to hypothyroidism of Hashimoto's disease simulating the musculoskeletal symptoms of polymyositis.

Localized myxedema is an uncommon complication of Graves' disease. It is characterized by the accumulation of glycosaminoglycans, particularly hyaluronate. Here we describe the case of a 51-year-old female patient suffering from Graves' disease, who has presented for years a thickening of the scalp, consistent with myxedema, and successfully treated with repeated injections of hyaluronidase.

Hyaluronidase is mostly widely recognized for its off-label use in correction of complications of hyaluronic acid fillers. However, its utility in other aspects of dermatology is less widely acknowledged. We describe the varied uses of hyaluronidase in dermatology and the underlying evidence base for its dermatological indications. This includes its uses in enhancing drug delivery (for local anesthesia, keloid and hypertrophic scars, and for Kaposi’s sarcoma), in the treatment of disorders associated with mucin deposition (myxedema, scleroderma, scleredema, and cutis verticis gyrata) and its potential uses in surgery (as a pre-operative adjuvant in dermatofibrosarcoma protuberans, for periorbital edema, and for hematomas). In select circumstances, hyaluronidase might be more efficacious than more established treatments with fewer adverse effects. We propose hyaluronidase as the latest addition to our global dermatological armamentarium and implore dermatologists to consider its use to enhance
