Contact dermatitis in patients with leg ulcers.

The incidence of contact allergy to 63 substances, including active principles and excipients used in a variety of topical preparations, has been studied by patch testing in 306 patients being treated conservatively for stasis dermatitis with or without ulceration. Positive reactions to one or more test compounds were recorded in 177 patients. The main offenders among drugs were neomycin, sulphonamide and promethazine; among the excipients, they were parabens, lanolins and benzoyl peroxide. Frequent reactions were observed to certain substances of the 'para' group, benzocaine, diaminodiphenylmethane, aniline and paraphenylendiamine, with the first three acting mainly as indicators of cross-sensitization. The extension and spread of allergic dermatitis can also be produced by drugs administered systematically. Recognition of the allergens responsible for allergic contact dermatitis arising at the lower leg site is a necessary condition if chronicity and spread of the dermatitis are to be prevented. For the same reason it is important to restrict topical applications to non-allergic substances.

Allergy to various components of topical preparations in stasis dermatitis and leg ulcer.

Patients suffering from stasis dermatitis and leg ulcers (192) were found to give an allergic reaction in epicutaneous tests to one or more components of topical preparations in 69.2% of cases. The most common reactions were obtained with neomycin 34.0% and its component framycetin 31.2%, wool alcohols 22.9%, balsam of Peru 21.4%, chlorquinaldon 16.7%, bacitracin 13.1%, chinoform 10.9%, dequalin 9.9%, formaldehyde 4.2% and parabens 3.6%. The incidence of allergic reactions reflects local use of preparations containing various allergens as well as their capacity to produce alllergy. Allergy may in some cases interfere with effective topical therapy. Debrisan dextran polymer beads were found to be suitable for treatment of ulcers of multiallergic patients without risk of contact allergy.

Paraproteinaemia in erythema elevatum diutinum.

Paraproteinaemia (IgGkappa) was observed in a 68 year-old patient with erythema elevatum diutinum. The association of this skin disease with paraproteinaemia as already reported by other authors may indicate a pathogenetic relationship.

Cryofibrinogenemia, monoclonal gammopathy, and purpura. Report of a case and review of the literature.

A patient with purpura, acral blisters, and ulcerations was evaluated and found to have cryofibrinogenemia and an IgG K light chain monoclonal gammopathy. No other systemic illness was found. The overall incidence of significant cryofibrinogenemia include neoplastic, thrombotic, infectious, and miscellaneous disorders. The patient described was not easily classified. This case is probably best considered primary or idiopathic cryofibrinogenemia.

Porokeratosis of Mibelli. A report of two unusual cases.

2 cases are reported with unusual manifestations of porokeratosis of Mibelli. In 1 case multiple atrophic facial lesions resembled plaques of chronic discoid lupus erythematosus. The second case exhibited extensive cutaneous involvement in the form of hyperkeratotic lesions in linear configuration.

Keratolytic winter erythema or 'oudtshoorn skin': a newly recognized inherited dermatosis prevalent in South Africa.

A hitherto undescribed inherited dermatosis, traceable to certain 19th-century inhabitants of Oudtshoorn, CP, has been transmitted as an autosomal dominant to a large number of their present-day descendants. The disease consists of intermittent and recurrent centrifugal peeling, with redness, of the palms and soles in particular. In more severe cases similar patches are found extending up the limbs to the buttocks and the trunk generally. The inconvenience is usually moderate, but it may be incapacitating. Some temporary relief, but so far nothing permanent, can be offered through treatment.

Multiple persistent keratoacanthomas.

A unique case of multiple keratoacanthomas is described, with involvement of the face and lower extremities with persistent lesions clinically and histologically diagnostic of keratoacanthomas. The lower extremity lesions appear as giant keratoacanthomas, with evolution into a distinctive confluent plaque. This important tumor and its present classification are reviewed.
