Eccrine Hidrocystoma (Dermatoscopic Image)

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.
