Differential Diagnosis for Warts on the Cuticles of the Left Big Ring Finger
- Single most likely diagnosis:
- Periungual warts: This is the most likely diagnosis given the location of the warts on the cuticles of the finger. Periungual warts are a type of wart that occurs around the nails and are caused by the human papillomavirus (HPV).
- Other Likely diagnoses:
- Common warts (Verruca vulgaris): These are also caused by HPV and can occur on any part of the body, including the fingers.
- Flat warts (Verruca plana): These are small, flat warts that can occur on the hands and fingers.
- Mosaic warts: These are a type of wart that occurs when multiple warts grow together in a mosaic pattern.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- Squamous cell carcinoma: Although rare, squamous cell carcinoma can present as a wart-like lesion on the finger. It is a type of skin cancer that can be deadly if left untreated.
- Melanoma: In rare cases, melanoma can present as a pigmented lesion on the finger that resembles a wart.
- Rare diagnoses:
- Epidermoid cysts: These are small, benign cysts that can occur on the fingers and may resemble warts.
- Keratoacanthoma: This is a rare, benign tumor that can occur on the fingers and may resemble a wart.
- Verrucous carcinoma: This is a rare type of skin cancer that can present as a wart-like lesion on the finger.
