Brief Answer:
Post-Inflammatory hyperpigmentation
Detailed Answer:
Hi. Thanks for posting your concern at HCM
Regarding pigmentation in the groins, it is most likely post-inflammatory hyperpigmentation secondary to recurrent fungal infections which you experienced in the past and applying super-potent
steroids over there (Keto-B Ointment contains a super-potent steroid,
BETAMETHASONE) for long can do more harm than good causing side effects like skin thinning and
stretch marks. Therefore i would advice you against applying super-potent steroids in that area.
Pigmentation would lighten by itself gradually if the fungal infections are not allowed to recur. You can use an antifungal dusting powder in the folds regularly to prevent recurrence of fungal infections.
Persistent itching and scratching in the groin folds due to fungal infection, is also very commonly associated with the skin becoming thick and dark(this is called Lichenification). This thick skin in turn elicits more itching and thus becomes a cycle (itching leads to scratching and scratching leads to lichenification which in turn elicits more itching).
Using an antihistamine to control the itch helps break this cycle along with a topical steroid+antifungal cream, which targets the fungus and also acts as an anti-inflammatory.
-I would normally advice my patients an oral anti-fungal (
fluconazole 150mg once every week for 6 weeks).
-I also advice in my patients, a topical steroid+antifungal combination cream (clotrimazole+Beclomethasone) twice daily for 4-6 weeks. BECLOMETHASONE is a mild steroid as compared to BETAMETHASONE which is a super-potent steroid (present in Keto-B ointment).
-An OTC antihistamine like
cetrizine once daily in the evening will help you with the itch part
-Once my patients are cured(usually 4-6 weeks) i ask them to use an anti-fungal dusting powder (clotrimazole dusting powder) in the folds, so as to prevent recurrence.
Take care
