valacyclovir and Pruritus

Clopidogrel is an adenosine diphosphate receptor antagonist used for the prevention of vascular events in patients with atherothrombotic diseases manifested by recent myocardial infarction, ischemic stroke or peripheral arterial disease. Diarrhoea, rash and pruritus are rather common side effects of clopidogrel. Other side effects include epistaxis, nausea, abdominal pain, vomiting, gastritis, gastric and duodenal ulcer. Thrombocytopenia is the most common laboratory abnormality. Leucopenia and neutropenia are rare. We report three cases of purpuric herpes zoster in patients in therapy with clopidogrel. To our knowledge, only one case of haemorrhagic herpes zoster has been published in a patient in therapy with this drug.

Cutaneous eruptive xanthomas are characteristics lesions of hyperlipidemia. Rarely,these lesions may present with prominent leukocytoclasis as seen in papular neutrophilic xanthomas, which have been described in HIV positive and immunocompromised patients. Herein we describe a patient with eruptive neutrophilic xanthomas with neither hyperlipidemia nor immunocompromise. Moreover, these lesions improved with sun and UV light exposure.
