A case of eccrine angiomatous nevus in a 46-year-old woman is described. The histological examination revealed convolutions of eccrine sweat glands with no major structural abnormalities, and a closely related angiomatous component. Two components of this tumour are of special interest: the bone formation and a medium-sized artery with pathologic wall structure.
A 44-year-old female with Sneddon's syndrome, i.e. generalized racemose livedo and recurrent cerebrovascular disease, is presented. Significant levels of IgG anticardiolipin antibodies were found in her serum.

We report on an 81-year-old woman suffering from extensive acrodermatitis chronica atrophicans with facial involvement. This unusual manifestation may be related to an immunodeficiency state in the course of multiple malignancies. The cutaneous lesions cleared significantly during an aminopenicillin therapy administered orally over 4 weeks.
Eccrine sweat gland carcinoma is a rare malignancy of skin adnexa with potential aggressive growth and metastatic spread. We report here a case of eccrine carcinoma arising on a finger with widespread pulmonary metastasis. A brief synopsis of the pathological and clinical aspects of eccrine sweat gland carcinoma is presented and currently available therapeutic modalities are discussed.
The pemphigus vulgaris lesions first developed in a 70-year-old man as a reaction to superficial X-ray treatment of solar keratoses on the forehead.
Irradiation of 20 tattoos using the Q-switched Nd:YAG laser (energy density 3-5 J/cm2, asymmetrical pulse shape with 50% energy output in 18 ns, spot size 3 mm in diameter) gave the impression that black ink tattoos can be completely removed without scarring. Some patients needed several treatments. The results continued to improve even some months after the irradiation. In preliminary experiments on excised tattooed and untattooed skin the non-Q-switched Nd:YAG laser had distinct burning effects. It was therefore not tested in patients. The results of chemical, physical, and histological examinations are discussed with special reference to toxic side-effects that might be induced by laser irradiation.
The larvae of green lacewings (Chrysopidae) may occasionally attack man as temporary ectoparasites, causing papular reactions similar to those produced by gnat bites.
Following glomerulonephritis with subsequent anasarca and repeated penicillin treatments, generalized cutis laxa developed in a forty-year-old patient. Progressive signs of pulmonary emphysema appeared in the same period. Additionally, a monoclonal gammopathy was detected during extensive examination.

Two patients, who we had under surveillance since 1969, were found to develop photo-onycholysis from orally administered 8-methoxypsoralen and sunlight irradiation. Morphological examination of the nail bed revealed characteristics of a microtrauma. The photosensitizing effect of the drug induced the generation numerous binucleate, tetranucleate and multinucleate epithelial cells as well as numerous binucleate and tetranucleate fibroblasts in the dermis.

The treatment of hemangiomas with X-rays has been sharply criticized because of their tendency to involute spontaneously. It has been the aim of this catamnestic study to re-examine for X-ray injury those patients, whose hemangiomas were irradiated 15-20 years ago. The findings indicate that signs of roentgenoderma can appear already with 800 r and increase rapidly over 1,500 r. The observed irreversible damages, however, were mostly not grave, but admonish a certain amount of restraint. An assessment of the effectiveness of low X-ray doses still requires verification considering a faster spontaneous involution.
Focal dermal hypoplasia (Goltz's syndrome, Goltz-Gorlin syndrome), an uncommon malady belonging to the group of congenital poikloderma, is characterized by its broad spectrum of meso-ectodermal defects involving the skin as well as the eyes, skeletal system and teeth. The case represented her is identical with the one published by Naegeli 1926, and contains some additional findings that have not yet been reported, namely: multiple hidrocystomas, bilateral keratoconus, papillomatosis of esophagus, hiatus hernia.
