Lipschütz ulcer – This is a rare and acute form of genital ulcers that primarily affects young, sexually active women. While it was initially described in the context of infectious mononucleosis, these ulcers can occur in the absence of this infection. Other factors, such as viral or bacterial infections, systemic illnesses, and hypersensitivity reactions, have been suggested as potential triggers. The condition is characterized by the sudden appearance of painful, shallow ulcers on the labia minora, vestibule, or perineum. The ulcers are typically solitary or few, with well-defined borders. They may be associated with systemic symptoms such as fever and malaise.17
