We present an unusual case of a rare vascular disorder known as blue rubber bleb nevus syndrome (BRBNS). While many cases of BRBNS occur sporadically, some have been associated with an autosomal dominant inheritance pattern with a locus on chromosome 9p [1]. Furthermore, BRBNS causes vascular malformations to occur in the skin and the gastrointestinal (GI) tract. GI bleeding is a common cause of morbidity in these patients [2]. This syndrome affects males and females in equal numbers [3].

A nineteen-year-old male presented with several soft, blue, and easily compressible papules on the trunk (Figs. 1 – 3). These papules were painful to palpation and had been present for years. The patient was referred to a dermatologist by the pediatrician as new papules described recently appeared. Additionally, an ultrasound of the trunk interpreted the areas involved as lipomas. The pertinent history includes the diagnosis of BRBNS in the patient’s uncle and diagnosed with BRBNS by the dermatologist. Finally, the patient was referred to gastroenterologist consultation for colonoscopy to evaluate possible vascular malformations in the GI tract.
