stubborn lesion
Is this stubborn lesion a “callus” - or something else?
Case 2: A 42-year-old woman complains of a “callus” of 6 months’ duration on the thumb of her dominant hand. The persistent lesion responds to the use of a pumice stone and moisturizers but quickly returns.
What do you suspect?
- Callus.
- Wart.
- Dyshidrosis.
- Psoriasis.
- Fungal infection.
Answer: Wart
The stubborn lesion was a wart, B, which responds to salicylic acid or cryosurgery. The patient opted for the more expeditious cryosurgery. The lesion did not have the clinical appearance of a callus. Psoriasis and fungal infection eruptions are erythematous and scaly. The lesions of dyshidrosis are vesicular.
