Acute haemorrhagic oedema of infancy associated with cytomegalovirus infection.

Acute haemorrhagic oedema (AHO) of infancy is a cutaneous leukocytoclastic vasculitis, clinically characterized by the acute development of peripheral oedema and targetoid purpuric lesions on the face and extremities. It usually affects children younger than 2 years of age. The disorder follows a benign course usually without recurrence or long-term complication. In most cases the origin is not clear, but underlying infections are assumed to play an aetiological role. We describe a 7-month-old boy whose clinical and histopathological features are typical of AHO. Serological tests clearly demonstrated a primary infection for cytomegalovirus (CMV). To our knowledge, this is the first reported case of AHO associated with CMV infection.

Etizolam-induced superficial erythema annulare centrifugum.

Erythema annulare centrifugum (EAC) is characterized by slowly enlarging annular erythematous lesions. Although the origin is not clear in most cases, EAC has been associated with infections, medications, and in rare cases, underlying malignancy. We describe a patient who developed annular erythematous lesions after etizolam administration. The eruptions were typical of the superficial form of EAC, both clinically and histopathologically. The lesions disappeared shortly after discontinuation of the medication. Patch testing with etizolam gave positive results. To our knowledge this is the first reported case of etizolam-induced superficial EAC.
