Differential Diagnosis for Irregularly Shaped, Red, Dry Patch with Satellite Small Erythematous Pustules
- Single Most Likely Diagnosis
- Candidiasis: This condition is characterized by red, dry patches and satellite pustules, which are small, erythematous, and pus-filled. The presence of these satellite lesions is a hallmark of candidiasis, making it the most likely diagnosis.
- Other Likely Diagnoses
- Contact Dermatitis: This condition can cause red, dry, and irregularly shaped patches, especially if the patient has come into contact with an allergen or irritant. However, the presence of satellite pustules is less common in contact dermatitis.
- Seborrheic Dermatitis: This condition can cause red, dry patches, but it typically does not present with satellite pustules. However, it can be considered in the differential diagnosis due to its common occurrence.
- Psoriasis: While psoriasis can cause red, dry patches, it typically presents with well-defined plaques and silvery scales, rather than satellite pustules.
- Do Not Miss Diagnoses
- Infectious Eczematoid Dermatitis: This is a rare but serious condition that can present with similar symptoms to candidiasis, including satellite pustules. It is often associated with an underlying infection, such as tuberculosis or lymphoma, and requires prompt diagnosis and treatment.
- Kerion: This is a rare but serious fungal infection of the scalp that can cause red, dry patches and satellite pustules. It requires prompt diagnosis and treatment to prevent long-term hair loss and scarring.
- Rare Diagnoses
- Pityriasis Rosea: This is a rare condition that can cause red, dry patches, but it typically does not present with satellite pustules. However, it can be considered in the differential diagnosis due to its unique presentation.
- Granuloma Gluteale Infantum: This is a rare condition that can cause red, dry patches and satellite pustules in the diaper area of infants. However, it is relatively rare and typically only occurs in infants.
