ABSTRACT
Scabies, a common and highly contagious skin infestation, is caused by the mite Sarcoptes scabiei var. hominis. Identifying individuals with scabies often poses a diagnostic challenge, as its clinical features resemble other dermatologic conditions such as drug reactions, atopic dermatitis, and contact dermatitis. Furthermore, the cutaneous manifestations arise from delayed-type immunologic reactions to the mites and their byproducts, allowing some individuals to carry the mite without showing symptoms. The significant transmissibility of scabies, along with the potential for asymptomatic carriers, creates multiple treatment hurdles for cohabiting individuals, as the failure to treat all close contacts can result in re-infestation. This report presents the case of a 46-year-old Vietnamese male who suffered from a worsening erythematous, scaly, and pruritic rash for four months. Despite being prescribed topical corticosteroids by three different dermatologists, his rash persisted. Upon thorough evaluation, scabies was diagnosed. The patient was treated with scabicidal agents, which initially alleviated his symptoms; however, three weeks later, his symptoms resurfaced. Further investigation revealed that his wife was an asymptomatic carrier who had not received treatment. This case highlights the clinical features, pathogenesis, and treatment options for scabies while emphasizing the importance of promptly identifying and treating all close contacts.
