Differential Diagnosis for Red, Tender Bumps in Bilateral Gluteal Folds
Single Most Likely Diagnosis
- Intertrigo: This is a common condition characterized by inflammation of the skin folds, often caused by friction, heat, and moisture. The symptoms worsen with heat and humidity, making it a likely diagnosis for red, tender bumps in the gluteal folds.
Other Likely Diagnoses
- Folliculitis: An infection of the hair follicles, which can be caused by bacterial, viral, or fungal pathogens. The warm, moist environment of the gluteal folds can contribute to the development of folliculitis.
- Contact Dermatitis: A type of skin inflammation caused by contact with an irritant or allergen. This could be due to friction, soap, or other substances coming into contact with the skin in the gluteal folds.
- Candidiasis: A fungal infection that thrives in warm, moist environments, making the gluteal folds a susceptible area.
Do Not Miss Diagnoses
- Cellulitis: A bacterial skin infection that can spread rapidly and become severe if left untreated. While less likely, it's crucial to consider cellulitis due to its potential for serious complications.
- Abscess: A pocket of pus that can form in the skin, often requiring drainage. An abscess in the gluteal fold could present as a red, tender bump.
- Necrotizing Fasciitis: A rare but life-threatening infection that destroys skin and underlying tissue. Although unlikely, its severity warrants consideration in the differential diagnosis.
Rare Diagnoses
- Hidradenitis Suppurativa: A chronic skin condition characterized by recurring, painful abscesses and nodules in the apocrine-gland-bearing areas of the body, such as the gluteal folds.
- Keratosis Pilaris: A condition causing small, rough bumps on the skin, often on the arms, legs, and buttocks. While it can appear in the gluteal folds, it's less likely to cause tender bumps.
- Erythema Ab Igne: A condition caused by prolonged exposure to heat, resulting in reticulated erythema and potentially leading to more serious skin changes.
