A Case Report: Lichen Simplex Chronicus Mimicking Bowen’s Disease

Lichen simplex chronicus (LSC), also known as ‘’neurodermatitis’’. It can present clinically as isolated or multiple lichenified thickened plaques that are usually hyper pigmented and excoriated with accentuated skin markings. The diagnosis of LSC is usually easily made from characteristic lesions. In more difficult cases histopathological study is useful. A 59–year–old male patient had a one-year history of erythema and crusts beginning on the left lumbar region and enlarging peripherally. His past medical history was unremarkable. Dermatological examination revealed 3x4 cm sharply demarcated, erythematous, slightly scaling and crusted solitary plaque on the left lumbar region.  Because of  the clinical characteristics of the lesions, Bowen’s disease was suspected clinically in the diagnosis of the disease. Histological examination was compatible with the diagnosis of LSC.  Thus, a diagnosis of Bowen’s disease was eliminated. Our case is presented in order to remind that LSC should be kept in mind, in differential diagnosis of  Bowen’s disease
