Case of the Week 293

Several hairs from the groin region of a 24 year old male were submitted to the Clinical Parasitology lab for examination.  One hair contained the following structure cemented onto the hair shaft.  It measures approximately 2 mm in length.  Identification?

Phthirus pubis, note the angle against the hair and the raised operculum. However 2mm seems large for the egg, unless of course the measurement was taken from the end of the cement-like secretion
