Differential Diagnosis for Recurrent Labial Abscess
- Single most likely diagnosis
- Furuncle or Carbuncle: A furuncle (boil) or carbuncle, which is a group of furuncles, is the most likely diagnosis given the patient's history of a recurrent labial abscess that has been draining. This condition is typically caused by Staphylococcus aureus and can be recurrent due to bacterial colonization or poor hygiene.
- Other Likely diagnoses
- Folliculitis: An inflammation of the hair follicles, which can lead to abscess formation, especially if the patient has been shaving or waxing the area, causing irritation and introducing bacteria into the follicles.
- Hidradenitis Suppurativa: A chronic skin condition characterized by recurrent abscesses and nodules, often in areas with apocrine glands, such as the groin. Although less common, it could be considered given the recurrent nature of the abscess.
- Infected Bartholin's Cyst: If the abscess is located near the vaginal opening, an infected Bartholin's cyst could be a possibility, especially if the patient reports symptoms like a painful lump or difficulty walking.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Necrotizing Fasciitis: Although rare, necrotizing fasciitis is a life-threatening condition that requires immediate attention. It is characterized by rapid progression of infection, severe pain, and signs of systemic illness.
- Methicillin-Resistant Staphylococcus aureus (MRSA) Infection: MRSA can cause severe skin and soft tissue infections, including abscesses. It is essential to consider this diagnosis, especially if the patient does not respond to standard antibiotic therapy.
- Rare diagnoses
- Actinomycosis: A rare bacterial infection that can cause abscesses, often in the face and neck area. It is usually associated with poor dental hygiene or the use of intrauterine devices (IUDs).
- Tuberculosis: Although rare, cutaneous tuberculosis can cause abscess-like lesions, especially in immunocompromised patients or those from endemic areas.
