Verrucous Haemangioma with Histoid Leprosy: A Case Report

Verrucous Haemangioma (VH) is a rare, congenital vascular malformation of cutaneous and subcutaneous tissue. It usually presents as macular lesion at birth which progresses with age, and may become bluish papules, nodules, and warty plaques. Linear presentation of this disease is even rarer. Here the present case report presents a case of a 30-year-old male patient with multiple raised erythematous hyperkeratotic papules and plaques over right forearm since birth which was arranged in a linear pattern.The patient also had asymptomatic papules on right thigh and lower back region, associated with sensory loss and peripheral nerve thickening. Dermoscopy of forearm showed reddish-blue lacunae, alveolar pattern, and whitish veils. Colour Doppler showed intradermal dilated venous channels with thrombosis which was suggestive of haemangioma. Histopathological examination confirmed the diagnosis of linear VH on forearm and slit skin Ziehl-Neelsen staining was suggestive of histoid leprosy. Linear VH is a rare congenital venous malformation, progresses proportionately with age. Dermoscopy can help in early diagnosis of vascular lesions. Complete surgical excision is the treatment of choice.
