Differential Diagnosis for Small Lesions on Left Hand
Single Most Likely Diagnosis
- Milia: Small, non-pruritic, and non-erythematous lesions on the hand could be milia, which are small, white bumps that occur when dead skin cells or keratin get trapped under the skin surface.
Other Likely Diagnoses
- Seborrheic keratoses: These are benign growths that can appear as small, non-pruritic, and non-erythematous lesions on the skin, often on the hands.
- Syringomas: These are small, benign tumors that can appear as non-pruritic and non-erythematous lesions on the skin, often on the hands.
- Eccrine poroma: A rare, benign tumor of the sweat glands that can appear as a small, non-pruritic, and non-erythematous lesion on the hand.
Do Not Miss Diagnoses
- Squamous cell carcinoma: Although less likely, it's crucial to consider skin cancer, especially if the lesion is new, growing, or has an unusual appearance.
- Merkel cell carcinoma: A rare, aggressive skin cancer that can appear as a small, non-pruritic, and non-erythematous lesion on the skin.
- Lymphoma: Cutaneous lymphoma can manifest as small, non-pruritic, and non-erythematous lesions on the skin, although this is relatively rare.
Rare Diagnoses
- Glomus tumor: A rare, benign tumor of the glomus body that can appear as a small, non-pruritic, and non-erythematous lesion on the hand, often under the nail.
- Neurofibroma: A rare, benign tumor of the nerve tissue that can appear as a small, non-pruritic, and non-erythematous lesion on the hand.
- Dermatofibroma: A rare, benign growth that can appear as a small, non-pruritic, and non-erythematous lesion on the skin, often on the hands.
