[Adamantinoid basal cell carcinoma]

The adamantinoid basal cell epithelioma is a clinically uncharacteristic but histologically typical variant of basal cell epithelioma characterized by a meshwork of stellate tumor cells.

[Detection of immunoglobulin deposits in paraffin embedded skin with the peroxidase-antiperoxidase (PAP) method]

The peroxidase-antiperoxidase (PAP) technique allows the detection of immunoglobulin deposits in formalin-fixed, paraffin-embedded tissue. The PAP technique may be used as an alternative to the direct immunofluorescence method on frozen, unfixed skin. In addition, the PAP technique is suitable for retrospective evaluation of histological samples.

[How do I treat dyshidrosiform eruptions?]

Dysfunction of sweat glands and acrosyringia are not involved in the pathogenesis of dyshidrosis. Clinically, dyshidrotic dermatitis (atopic, toxic, contact allergic, hematogen-allergic) and dyshidrotic tinea should be differentiated. Therapeutic possibilities comprise symptomatic topical and systemic treatment, whereas causal treatment is only possible in cases of tinea.

Are acrosyringia involved in the pathogenesis of "dyshidrosis"?

Investigations of dyshidrotic eruptions of various causes were done by conventional and electron microscopy. In all cases, the histological patterns were identical. The dyshidrotic vesicle is an intraepidermal, spongiotic lesion. The intraepidermal part of the eccrine sweat duct (acrosyringium) is not altered even by spongiosis. As the acrosyringium does not take part in formation of a dyshidrotic vesicle, the term "dyshidrosis" has to be regarded as a misnomer. Dyshidrosis is nothing but spongiotic dermatitis modified by the distinctive characteristics of palmar and plantar skin.

[Erythema chronicum migrans with Bannwarth syndrome (Garin-Bujadoux-Bannwarth meningopolyneuritis)]

A 54-year-old male had erythema chronicum migrans (ECM), lymphocytic meningitis, and intense pain radiating along the distribution of the corresponding dermatomal segments. Neurologic involvement, described as Bannwarth syndrome or meningopolyneuritis Garin-Bujadoux-Bannwarth, is a typical late manifestation of ECM infection and requires high-dose intravenous penicillin therapy.

[Traumatic ulcer following microwave irradiation and local anesthesia]

After microwave irradiation with simultaneous field anesthesia, acute ulceration was observed. The danger of this complication following irradiation of areas with reduced sensitivity is stressed.

[Finger varicose veins of the aged]

Palmar and finger varicosis is a common abnormality of the veins in the elderly. This often overlooked age-related condition is illustrated by three observations.
