A misdiagnosed case highlights crusted scabies mimicking psoriasis. Prompt diagnosis and treatment with permethrin and ivermectin are crucial for managing this contagious skin condition.

Area of Science:

  • Dermatology
  • Parasitology

Background:

  • Psoriasis and crusted scabies can present with similar skin symptoms, leading to diagnostic challenges.
  • A 67-year-old woman initially diagnosed with psoriasis was treated with topical calcipotriol and methotrexate.
  • The patient's husband had a history of chronic pruritus, suspected to be scabies.

Observation:

  • The patient presented with a year-long history of nail thickening and a non-itchy erythematous scaly eruption on the fingertips.
  • A diagnostic review prompted by the husband's persistent pruritus led to further investigation.
  • Skin scraping confirmed the presence of numerous mites, indicating crusted scabies.

Findings:

  • The patient was successfully treated with topical permethrin, keratolytics, and oral ivermectin.

  • This case underscores the importance of considering scabies in differential diagnoses, especially with a history of exposure.
  • Literature review on crusted scabies management and recommendations are provided.

    • Implications:

    • Accurate and timely diagnosis of crusted scabies is essential to prevent its spread and manage effectively.
    • Crusted scabies requires a different treatment approach than psoriasis, emphasizing the need for careful dermatological evaluation.
    • This case highlights the importance of considering the patient's social and family history in complex dermatological presentations.
