Case Reports
[Spinocellular cancers and myxoid atypical fibroxanthoma of an actinically damaged burn scar].
We report on a 66-year-old male patient suffering from several squamous cell carcinomas and a myxoid atypical fibroxanthoma of the skin. The tumours developed in burn scars that the patient had had for more than 50 years and that had in part undergone actinic elastosis. The role of burn scars in the development of different skin tumours is pointed out. In addition, we discuss the differential diagnosis of the rare myxoid variant of atypical fibroxanthoma.

Apocrine chromhidrosis is an extremely rare and impressive skin disorder. Primarily after emotional stress patients complain of coloured sweat secretion (black, green, blue or yellow). The deposition of lipofuscin in the apocrine glands may be the cause of this disease, the different colours of sweat being due to various oxidation stages of lipofuscin. We report two patients, one with blue and one with green axillae; the clinical features, histopathology, differential diagnosis, and pathogenesis of apocrine chromhidrosis are discussed.
