Case ReportsRenal angiogram abnormalities in a case of cutaneous polyarteritis nodosa.
The existence of a limited cutaneous form of polyarteritis nodosa remains controversial. It has been characterized and contrasted with systemic polyarteritis nodosa by running a chronic course and having a relatively good long-term prognosis. We report a case with clinical features fitting the criteria for cutaneous polyarteritis nodosa but also showing evidence of associated renal aneurysms on selective visceral angiography. These findings suggest that the differentiation between systemic and cutaneous forms might be an oversimplification and we discuss the relationship between the two forms.

Rubber is an important industrial and consumer product encountered in many household items and medical devices. Whereas the chemical additives used in its manufacture are well recognized as a cause of delayed-type hypersensitivity (allergic contact dermatitis), it is only during the past decade that immediate-type allergy to natural rubber latex (NRL) proteins (latex allergy) has emerged as a serious health issue. ⋯ Undiagnosed latex allergy is potentially very serious for patients. This article briefly overviews latex allergy with emphasis on the practical issues of diagnosis and management.

Case ReportsHyperpigmentation caused by hyperthyroidism: differences from the pigmentation of Addison's disease.
Two cases of hyperthyroidism with hyperpigmentation are presented. In both cases, hyperpigmentation was seen on the lower extremities, most strikingly on the shins, backs of the feet and the nail bed. ⋯ Treatment with mercazol in both cases resulted in no significant waning of pigmentation. Distribution of hyperpigmentation, haemosiderin deposition and poor response to the treatment may be characteristic features of the pigmentation caused by hyperthyroidism, and may represent differences from the pigmentation seen in Addison's disease.
