Cutaneous Crohn's can cause fistulas and "knife-cut" ulcers in the genital area, a different presentation than the discrete, cystic swelling of a Bartholin cyst.
While both are cysts, a Bartholin cyst is specifically located at the 4 or 8 o'clock position of the vaginal introitus, arising from the Bartholin gland itself.
This is a superficial infection of multiple hair follicles, presenting as small pustules, unlike the deeper, singular, cystic nature of a Bartholin cyst.
These are verrucous (warty) papules caused by HPV, a completely different morphology from a smooth, subcutaneous cyst.
This chronic inflammatory condition involves recurrent, painful nodules, abscesses, and scarring in intertriginous areas, a more extensive and chronic process than a single Bartholin cyst.
A pilonidal sinus is located in the midline of the natal cleft (top of the buttocks), a distinct location from the vulva.
A primary syphilitic chancre is a painless ulcer, not a cyst, while secondary syphilis can cause condylomata lata, which are flat, moist, wart-like lesions.
