INTRODUCTION
Shagreen patch (SP) was first described by Hallopeau and Leredde in 1895. Since then it has been reported to be present in 20-50% of cases of tuberous sclerosis [1].
SP is a connective tissue nevus that presents as a firm to rubbery irregular hyperpigmented rough plaque ranging in size from 1 to 10cms. The surface may resemble the surface of an orange peel. It is commonly located over the back, buttocks, thighs and nape of neck [1,2].
Although, diagnosis is easy, it can be mistaken for inflammatory verrucous epidermal nevus, plaques of other inflammatory skin conditions. Diagnosis is usually on clinical background. Sometimes biopsy is necessary to confirm the diagnosis [3].
Dermoscopy, a non-invasive, in vivo technique for the microscopic examination of pigmented skin lesions, has the potential to improve the diagnostic accuracy [4].
It can be utilized as a diagnostic aide in the diagnosis of SP. Authors evaluated the dermoscopic patterns of SP and hence, it is useful in diagnosis.
