Scabies: Are There Long-Term Effects and Symptoms? - Dermatology

Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition characterized by intense itching and a rash. It is particularly common in children and can lead to significant discomfort if not treated properly. Your child's ongoing symptoms, including the presence of granulomas and new lesions, raise important questions about potential long-term effects and the possibility of residual symptoms following treatment.

Firstly, it is essential to understand that while scabies itself is treatable, the skin can take time to heal after the infestation has been eradicated. The intense itching associated with scabies can lead to scratching, which may cause secondary infections or skin damage. This can result in post-scabetic dermatitis, where the skin remains inflamed and itchy even after the mites have been eliminated. This condition can manifest as red, raised bumps or granulomas, which may take weeks to months to resolve completely.

The granulomas you describe, particularly in the armpits and inner arms, could be a result of the body's inflammatory response to the scabies infestation or secondary infections from scratching. These lesions can sometimes persist even after the scabies mites have been treated. It is not uncommon for children to experience residual itching and skin changes for some time after treatment, especially if they had a severe infestation.

In terms of long-term effects, scabies itself does not typically cause permanent damage to the skin. However, if the infestation leads to significant scratching and subsequent skin infections, there could be scarring or changes in skin texture. It is crucial to monitor the lesions closely. If they become increasingly red, swollen, or painful, or if new lesions continue to appear, it may indicate a secondary infection or an incomplete treatment response.

Regarding the treatment regimen you mentioned—sulfur baths and topical medications—these are standard approaches for managing scabies. However, if symptoms persist, it may be necessary to consult a dermatologist or a healthcare provider specializing in infectious diseases. They may recommend further evaluation, including skin scrapings or biopsies, to confirm the absence of mites or to rule out other skin conditions.

In summary, while scabies can lead to temporary skin changes and discomfort, it typically does not result in long-term effects if treated appropriately. The symptoms your child is experiencing could be related to the body's healing process after the infestation. Continuous monitoring and follow-up with healthcare providers are essential to ensure that any lingering symptoms are addressed and to prevent complications. If you have concerns about the effectiveness of the treatment or the persistence of symptoms, do not hesitate to seek a second opinion or further evaluation.
