Papular urticaria often occurs after bites of insects such as mosquitoes, sandflies, bed bugs and fleas. Multiple bites and local pruritus are characteristic symptoms. Treatment is usually symptomatic and includes antihistamines and corticosteroids. The reappearance of the symptoms can be prevented by successful control of the parasite.
To find the causative agent of papular urticaria in afflicted households with involvement of numerous family members, all in a narrow geographic area.
We describe the cases of 20 patients belonging to seven families, who presented to the local primary clinic, suffering from papular urticaria.
The cat flea, Ctenocephalides felis, was the hematophagous insect responsible for all infestations. The pruritus and the papular urticaria were treated symptomatically with calamine lotion, topical corticosteroids or oral antihistamines. All clinical symptoms disappeared within a few weeks after effective control of the parasites by spraying and fumigating the infested locations.
Thorough investigation--including, at times, environmental inspection--is necessary to reach the rewarding discovery of the etiology of household papular urticaria. This condition may arise in other environments of similar character.
丘疹性荨麻疹常发生于蚊虫、白蛉、臭虫和跳蚤等昆虫叮咬后。多处叮咬和局部瘙痒是其特征性症状。治疗通常为对症治疗，包括使用抗组胺药和皮质类固醇。成功控制寄生虫可预防症状复发。
在一个狭小地理区域内，找出累及众多家庭成员的丘疹性荨麻疹患病家庭的病原体。
我们描述了来自7个家庭的20例患者的病例，这些患者前往当地基层诊所就诊，患有丘疹性荨麻疹。
猫栉首蚤是所有感染的吸血昆虫。使用炉甘石洗剂、外用皮质类固醇或口服抗组胺药对症治疗瘙痒和丘疹性荨麻疹。通过对受感染地点进行喷洒和熏蒸有效控制寄生虫后，所有临床症状在几周内消失。
彻底调查——有时包括环境检查——对于成功发现家庭性丘疹性荨麻疹的病因很有必要。这种情况可能出现在其他类似特征的环境中。
