Abstract

            Hematidrosis, or bloody sweat, is a rare phenomenon with enigmatic pathogenesis. We present our second case of hematidrosis in a 13-year-old Thai girl that had bloody sweat frequently observed on her back, hands, legs and feet. Skin biopsy revealed areas of hemorrhage in the panniculus and blood-filled spaces in the dermis. These spaces were usually located just under the epidermis and next to hair follicles and eventually they broke the overlying epidermis and adjacent hair follicles, producing bleedings on her skin.  We detected continuity between these spaces and areas of hemorrhage in the panniculus. This presence of blood-filled spaces that eventuate in hemorrhage is similar to the findings disclosed in our first report [1]. Thrombosis (without vasculitis) of small capillaries was noted and was proposed as the cause of hemorrhage in hematidrosis.
