Case ReportsPretibial myxedema as the initial manifestation of Graves' disease.
Pretibial myxedema (PM) is a localized thickening of the pretibial skin due to accumulation of acid mucopolysacharides (glycosaminoglycans). Its pathogenesis is still under investigation. Pretibial myxedema, exophthalmus and thyroid acropachy are the dassic extrathyroidal manifestations of Graves' disease. ⋯ Histopathologic examination revealed deposition of mucopolysacharides in the lower dermis. Laboratory investigation showed elevated serum T3 and T4 and depressed TSH levels. In our patient, pretibial myxedema was the earliest manifestation, leading to the diagnosis of Graves' disease.

A 70-year-old male with a superficial granulomatous ulcer is reported. Histopathological findings were the same as those described for superficial granulomatous pyoderma, a recognized variant of classic pyoderma gangrenosum.

Case ReportsSuccessful treatment of postoperative pyoderma gangrenosum with cyclosporin.
Postoperative pyoderma gangrenosum (PPG), also known as postoperative progressive gangrene of Cullen, is a rare and rapidly evolving complication of surgical procedures. Since the first description by Cullen in 1924 (Surg Gynecol Obstet 1924; 38: 579-582) various case reports have been published. ⋯ The therapies used for pyoderma gangrenosum include systemic corticosteroids, azathioprine, dapsone, mercaptopurine, sulphasalazine, sulphapyridine, thalidomide, cyclophosphamide, clofazimine, isotretinoin, immunoglobulins and cyclosporin. We report on two patients with PPG following breast surgery who were successfully treated with low-dose cyclosporin (2.5-5 mg/kg per day).
