Patient's question:
A small, flesh-colored or oily lump (about the size of a blackhead) has grown near the labia (vulva), with a black center. It's not squeezable, painless, or itchy, and only noticeable during bathing. The doctor diagnosed it as a sebaceous cyst and prescribed erythromycin ointment and a vulva-cleaning liquid. After using it for a week without improvement, can I switch to Bacitracin? Could it be folliculitis or eczema? Are there other medications? Does it require surgery?Doctor's answer:
Folliculitis in its initial stage presents as red, or follicular impetigo that matches the size of the hair follicle opening. It then rapidly evolves into pustular papules, with a red halo surrounding the pustules. Eventually, it dries and forms a scab, which typically falls off and heals within about a week. However, it can also recur repeatedly, persist for years, or develop into a deep infection. Folliculitis generally does not leave scars.Sebaceous cysts often appear as single or multiple formations. Sometimes, small black dots caused by blocked sebaceous gland openings can be seen on the cyst surface. These cysts have a medium hardness or elasticity, are elevated above the skin surface, and have a smooth surface. Sebaceous cysts frequently become infected, leading to temporary resolution when the cyst ruptures. This can result in the formation of scars and make the cysts prone to recurrence. But
