Summary
Brucellosis can cause fever of unknown origin with distinct skin eruptions, including papules and erythema nodosum-like lesions. Blood cultures are crucial for diagnosis when skin biopsy findings are suggestive.
Area of Science:
- Dermatology
- Infectious Diseases
- Microbiology
Background:
- Fever of unknown origin (FUO) presents a diagnostic challenge.
- Cutaneous manifestations can be key indicators of underlying systemic infections.
Observation:
- A patient with FUO presented with two distinct types of skin eruptions: papules on the trunk/extremities and erythema nodosum-like nodules on the legs.
- Initial Brucella agglutinin tests were negative.
Findings:
- Blood culture confirmed infection with *Brucella melitensis*.
- Histologic examination of skin lesions revealed features suggestive of Brucellosis.
- Brucellosis diagnosis requires considering FUO with specific dermatologic findings.
Implications:
- Brucellosis should be included in the differential diagnosis for FUO with papular eruptions or erythema nodosum-like lesions.
- Dermatologic findings and skin biopsies can aid in diagnosing challenging Brucellosis cases.
- Early recognition of these cutaneous signs can lead to timely diagnosis and treatment of Brucellosis.
