Differential Diagnosis for Dry and Cracked Hand with Nail Loss
The patient presents with a dry and cracked hand, resembling a burn, but without a history of burns. The following differential diagnoses are considered:
- Single most likely diagnosis
- Eczema (Dyshidrotic): This condition is characterized by dry, cracked skin, and can occur on the hands, especially after nail loss or trauma. The dry environment and potential irritants may have triggered or exacerbated the condition.
- Other Likely diagnoses
- Contact Dermatitis: An allergic or irritant reaction to a substance that came into contact with the skin, causing dryness, cracking, and potentially resembling a burn.
- Psoriasis: A chronic skin condition that can cause dry, scaly, and cracked skin, potentially affecting the hands.
- Keratoderma: A condition characterized by thickening of the skin on the hands and feet, potentially causing dryness and cracking.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Scleroderma: A rare autoimmune disorder that can cause skin thickening, dryness, and cracking, potentially leading to more severe complications if left untreated.
- Raynaud's Phenomenon: A condition that affects blood flow to the fingers and toes, potentially causing dryness, cracking, and discoloration.
- Rare diagnoses
- Pemphigus: A rare autoimmune disorder that can cause blistering and dryness of the skin, potentially affecting the hands.
- Kawasaki Disease: A rare condition that can cause skin peeling, dryness, and cracking, especially on the hands and feet, although it is more commonly associated with fever and other systemic symptoms.
