Cutaneous manifestations of Lyme borreliosis
1Department of Dermatology, New York University School of Medicine, New York.
Abstract:
Erythema migrans is the distinctive cutaneous marker of Lyme borreliosis. The clinical picture is variable but at some point in its evolution, erythema migrans presents as a red, centrifugally expanding, annular plaque. Erythema migrans may appear as a solitary lesion or in multiplicity. It may be accompanied by extra cutaneous signs and symptoms as fever, headache, musculoskeletal discomfort, and regional lymphadenopathy. The diagnosis of erythema migrans is based primarily on clinical findings because serologic tests to detect elevated antibody levels to Borrelia burgdorferi are frequently negative during the first few weeks of the illness. Identification of Borrelia burgdorferi from skin biopsy specimens obtained from erythema migrans lesions microbiologically or histopathologically will confirm the clinical diagnosis of erythema migrans.
Insights
Erythema migrans, a skin rash from Lyme borreliosis, is diagnosed clinically. Early serologic tests for Borrelia burgdorferi are often negative, making early diagnosis challenging.
Area of Science:
- Dermatology
- Infectious Diseases
- Microbiology
Background:
- Erythema migrans is the hallmark skin manifestation of Lyme borreliosis.
- The rash typically appears as an expanding, annular red plaque, sometimes with multiple lesions.
- Associated symptoms can include fever, headache, and swollen lymph nodes.
Purpose of the Study:
- To describe the clinical presentation and diagnostic considerations for erythema migrans.
- To highlight the challenges in early Lyme borreliosis diagnosis due to serology limitations.
Main Methods:
- Clinical observation and description of erythema migrans.
- Review of diagnostic criteria and methods for Lyme borreliosis.
- Discussion of microbiological and histopathological confirmation techniques.
Main Results:
- Erythema migrans diagnosis relies heavily on clinical presentation.
- Serological tests for Borrelia burgdorferi antibodies are often negative in the early stages.
- Microbiological or histopathological identification of Borrelia burgdorferi confirms the diagnosis.
Conclusions:
- Clinical diagnosis of erythema migrans is primary, especially early in Lyme borreliosis.
- Confirmation can be achieved through laboratory identification of the causative agent in skin lesions.
