What is a characteristic symptom of scabies?

• A. Intensely pruritic erythematous papules
• B. Yellow crusted lesions
• C. Vesicular eruption on the scalp
• D. Ulcerated skin lesions

Answer: (A)

Scabies is characterized by intensely pruritic (itchy) erythematous papules due to an allergic response to the mites and their feces. The intense itching often worsens at night and can lead to secondary infections from scratching. The papules are typically found in specific areas, such as between the fingers, on the wrists, and in the genital area, often accompanied by burrows formed by the mites. The presentation of yellow crusted lesions is more indicative of impetigo or other bacterial infections, rather than scabies. Meanwhile, vesicular eruptions on the scalp might be related to conditions like herpes simplex or varicella rather than scabies. Lastly, ulcerated skin lesions can occur in various skin conditions but do not specifically characterize scabies, which is primarily associated with papular lesions and intense itching rather than ulceration.
