Differential Diagnosis for a Year-Old Female with Ringworm All Over the Body in Different Areas
- Single Most Likely Diagnosis
- Tinea corporis (ringworm): This is the most likely diagnosis due to the presence of ring-shaped lesions in different areas of the body, which is characteristic of tinea corporis. It's a common fungal infection that can spread through skin-to-skin contact or by touching contaminated objects.
- Other Likely Diagnoses
- Tinea capitis (scalp ringworm): Although the question mentions ringworm all over the body, it's possible that the infection started on the scalp and spread to other areas.
- Tinea pedis (athlete's foot) or tinea cruris (jock itch): These fungal infections can spread to other parts of the body, especially if the patient touches the affected area and then touches other parts of their body.
- Eczema (atopic dermatitis): Eczema can cause ring-shaped lesions, although they are typically more irregular and accompanied by other symptoms like itching and dry skin.
- Do Not Miss Diagnoses
- Lymphoma: Although rare, some types of lymphoma, such as mycosis fungoides, can cause skin lesions that resemble ringworm. Missing this diagnosis could have severe consequences.
- Sarcoidosis: This autoimmune disease can cause skin lesions, including those that resemble ringworm. It's essential to consider sarcoidosis, especially if the patient has other symptoms like lung problems or eye issues.
- Rare Diagnoses
- Pityriasis rosea: This rare skin condition can cause ring-shaped lesions, although they are typically accompanied by other symptoms like a herald patch and a distinctive distribution of lesions.
- Granuloma annulare: This rare skin condition can cause ring-shaped lesions, although they are typically more localized and accompanied by other symptoms like nodules or papules.
