[Erythema elevatum diutinum. A rare dermatosis with a broad spectrum of associated illnesses].

Erythema elevatum diutinum (EED) is a rare disease presenting with persistent red to yellow-brown papules or plaques which are mainly localized symmetrically on the extensor aspects of the hands and fingers, the elbows and the knees. The histology shows a leucocytoclastic vasculitis in early lesions and fibrosis of the dermis later on. Dapsone is the treatment of choice. Today, EED is usually assigned to the neutrophilic dermatoses in which an association with hematological disturbances is well documented. We report on a patient with EED and glioma WHO grade IV, a coincidence unreported hitherto. Additionally, we review the literature on diseases associated with EED.

[Angioma serpiginosum, a skin change along Blaschko lines?].

We present a 34-year-old woman with angioma serpiginosum on the medial aspect of the left thigh, extending to the groin and the lower abdomen, and on the volar aspect of the left forearm. In addition to the late onset, the distribution along the lines of Blaschko was a remarkable feature of this case. We therefore reexamined our recent cases of angioma serpiginosum. In 6 of 7 cases, the distribution indeed corresponded to the lines of Blaschko. Thus, we suggest adding angioma serpiginosum to the list of skin lesions that may follow the lines of Blaschko.

Livedo racemosa: a report of five cases.

We present 5 patients in whom the diagnosis of livedo racemosa gave rise to clinical and laboratory investigations revealing arterial disease of different etiologies. This presentation emphasizes the importance of not missing the clinical diagnosis of livedo racemosa.

Pigmentation following long-term bismuth therapy for pneumatosis cystoides intestinalis.

In the recent literature, only a few reports deal with generalized pigmentation caused by bismuth treatment. We report a patient developing generalized pigmentation of the skin and mucous membranes without further signs of chronic bismuth poisoning following long-term administration of bismuth for pneumatosis cystoides intestinalis. Bismuth deposits were documented in a skin biopsy.

Chronic cutaneous infection caused by Mycobacterium gordonae.

We report on a patient with a chronic nodular cutaneous infection histologically presenting with tuberculoid granulomas and growing Mycobacterium gordonae in culture from a biopsy. The lesions were treated surgically. M. gordonae is a potentially pathogenic environmental mycobacterium only rarely causing skin infections.

[Eccrine angiomatous nevus].

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.

[Sneddon syndrome].

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.

[Extensive acrodermatitis chronica atrophicans involving the face].

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.

Metastatic eccrine sweat gland carcinoma: case report.

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.

[Removal of tattoos with the Nd:YAG laser].

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.

[Acquired cutis laxa (elastolysis generalisata)].

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.

[Merkel cell carcinoma (trabecular carcinoma) of the skin].

The Merkel cell carcinoma was first designated some years ago by the descriptive term trabecular carcinoma. Both names refer to a skin tumor occurring in elderly patients. This is another example where ultrastructural differentiating criteria are necessary for a definite diagnosis i.e., identification of so-called neurosecretory-like granules by electron microscopy. We report clinical, histological, ultrastructural, and histogenetic aspects of such a disease in a woman suffering from a metastasizing Merkel cell carcinoma.
