The patient is a 21 year-old woman who has noticed a blue-purple papule on the bulb of the nose for two to three months. If traumatized, it extrudes a clear fluid.
O/E: There is a two mm in diameter bluish papule on the nose. It was punctured with a # 11 blade and a drop of crystal clear fluid was extruded.
Dermatoscopic image shows a blue papule with a dark center and a paler periphery.
Diagnosis: Probable Eccrine Hidrocystoma.
Plan: This could be excised with a 2-mm punch biopsy. It could also be observed.
