Describe urticaria papulosa.
Urticaria papulosa (formerly called lichen urticatus) is a variety in which the lesions are small and papular, developing usually out of the ordinary wheals. They appear as a rule suddenly, rarely in great numbers, are scattered, and after a few hours or, more commonly, days gradually disappear. The itching is intense, and in consequence their apices are excoriated. Sometimes the papules are capped with a small vesicle (vesicular urticaria). It is seen more particularly in ill-cared for and badly-nourished young children.
Describe urticaria hæmorrhagica.
Urticaria hæmorrhagica is characterized by lesions similar to ordinary wheals, except that they are somewhat hemorrhagic, partaking, in fact, of the nature of both urticaria and purpura.
Describe urticaria tuberosa.
In urticaria tuberosa the lesions, instead of being pea- or bean-sized, as in typical urticaria, are large and node-like (also called giant urticaria).
What is acute-circumscribed œdema?
In rare instances there occurs, along with the ordinary lesions of the disease or as its sole manifestation, sudden and evanescent swelling of the eyelids, ears, lips, tongue, hands, fingers, or feet (urticaria œdematosa, acute circumscribed œdema, angioneurotic œdema). One or several of these parts only may be affected at the one attack; in recurrences, so usual in this variety, the same or other parts may exhibit the manifestation.
(These œdematous swellings occurring alone might be looked upon, as they are by most observers, as an independent affection, but its close relationship to ordinary urticaria is often evident.)
