Spontaneous regression of Merkel cell carcinoma of the skin.

We report a 65-year-old man who presented with a Merkel cell carcinoma on his right ear, a small satellite nodule and regional lymph node metastases. No treatment was given because of his generally poor state of health. Spontaneous regression of all the lesions was observed within a month. Merkel cell carcinoma is a potentially aggressive tumour. Only four cases of spontaneous regression have been reported previously.

Focal dermal hypoplasia (Goltz syndrome): an adult case with multisystemic involvement.

Focal dermal hypoplasia (Goltz syndrome) is a rare congenital syndrome with suspected X-linked transmission that is characterized by a wide range of mesoectodermal defects. We describe a 39-year-old woman who had a peculiar phenotype and asymmetry of the body. Examination revealed atrophic erythematous and hyperpigmented linear streaks following Blaschko's lines, some of which were in a reticular or cribriform arrangement. Yellow, soft nodules caused by fat herniation were visible mainly in skin folds. The patient had multiple bone anomalies, including longitudinal striation of long bones (osteopathia striata). She had several ocular, dental, and kidney defects. Histopathologic examination showed a markedly thinned dermis that was replaced by adipose tissue.
