Erythema annulare centrifugum (EAC) is characterised by slowly enlarging annular erythematous lesions and is thought to represent a clinical reaction pattern to infections, medications, and rarely, underlying malignancy. Causative drugs include chloroquine, cimetidine, gold sodium thiomalate, amitriptyline, finasteride, etizolam etc. We present a case of 40-year-old woman who presented to us with a 10 days history of nonpruritic, peripherally growing annular erythematous eruption.

Dear Editor, Bullous pemphigoid (BP), a relatively common autoimmune blistering disease in the elderly, is characterized by large, tense bullae on urticarial, erythematous, or normal skin. However, atypical BP with polymorphic clinical presentations is rarely encountered, leading to misdiagnosis and delayed treatments (1). BP with lesions resembling erythema gyratum repens or figurate erythema has been regarded as a paraneoplastic phenomenon (1). Read More

A switch from cell-mediated to humoral immunity (helper T 1 [Th1] to helper T 2 [Th2] shift) during gestation plays a key role in placental immune tolerance. As a result, skin diseases that are Th2 mediated often worsen, whereas skin diseases that are Th1 mediated often improve during gestation. Also, due to fluctuations in glandular activity, skin diseases involving sebaceous and eccrine glands may flare, whereas those involving apocrine glands may improve during pregnancy. Read More

Introduction: Erythema annulare centrifugum is a rare cutaneous disease characterized by erythematous and violaceous annular plaques that usually involved the thighs and the legs. The eruption may be associated with an underlying disease and its accompanying characteristic symptoms. For these reasons, a full physical examination should be conducted to exclude underlying disorders. Read More

Palpable migratory arciform erythema is an entity of unknown etiology, with few published cases in the literature. The clinical and histopathological features of this disease are difficult to be distinguished from those of Jessner's lymphocytic infiltration of the skin, lupus erythematous tumidus and the deep erythema annulare centrifugum. We describe here the first two Brazilian cases of palpable migratory arciform erythema. Read More

Erythema annulare centrifugum (EAC) is a reactive erythema with distinct, annular, erythematous plaques with trailing scale. This condition has been associated with various etiologies, which include an associated malignant condition. EAC with cancers or paraneoplastic erythema annulare centrifugum eruptions (PEACE), is more likely to be associated with lymphoproliferative malignancies such as lymphomas and leukemias. Read More

The article reports survey data on 23 patients with erythemas, including 19 patients with herpes-associated erythema multiforme (HAEM) and 4 patients with Darier's erythema annulare centrifugum (DEAC). Patients in the initial state (baseline) and after two weeks of therapy with proteflazid were characterized by measuring the levels of Toll-like receptor (TLR) expression in peripheral blood mononuclear cells (PBMC) and in epithelial cells of the throat and the skin. The TLR expression in PBMC and skin was assessed by flow cytometry with monoclonal antibodies (ICA) (Caltag Laboratories, USA; Hycult Biotech, Netherlands) against relevant antigens. Read More

Erythema papulatum centrifugum (EPC) was first described in 1962 by Watanabe [Jpn J Dermatol 1962;72:573] as eczematous lesions extending centrifugally. To date, more than 150 cases have been reported, but only in the Japanese literature. A review of the Japanese literature including our 5 new cases reveals that EPC occurs in middle-aged persons, predominantly in males, as a single lesion on the trunk that is self-limiting but recurs frequently.
