Vulvar sebaceous adenitis
Vulvar sebaceous adenitis presents with one or more painful and tender yellowish-orange or erythematous papules on the labia minora. Some have been noted to discharge pus. The condition typically worsens in the luteal phase of the menstrual cycle and improves or resolves with the onset of menstruation. Cases that are menstrual cycle-independent have also been reported.
It is thought that cycle variation occurs as the sebaceous gland is under hormonal influence.
