Summary
This study explores a rare fungal infection, Paracoccidioidomycosis, prevalent in the Amazon. Gallium-67 imaging showed potential for assessing disease extent and treatment effectiveness in this cutaneous mycosis.
Area of Science:
- Medical Mycology
- Nuclear Medicine
- Dermatology
Background:
- Paracoccidioidomycosis (P. loboii) is a rare mycosis primarily affecting indigenous Amazonian populations.
- It typically manifests as a cutaneous disease, with visceral involvement rarely described.
- Generalized skin disease and cheloid presentations have been reported.
Observation:
- A case of cheloid Paracoccidioidomycosis was investigated using gallium-67 scintigraphy.
- Gallium-67 uptake was observed in the affected skin lesions and a lymph node.
- Lymphadenopathy is uncommon in this condition.
Findings:
- Accumulation of gallium-67 in affected areas and a lymph node was noted.
- The degree of radiopharmaceutical accumulation was discrete to moderate.
- The patient had a history of irregular treatment for ten years.
Implications:
- Gallium-67 scintigraphy may aid in evaluating the extent of Paracoccidioidomycosis.
- This imaging technique could potentially assess the efficacy of treatment for this mycosis.
- Further research is warranted given the lack of laboratory data for Paracoccidioidomycosis evaluation.
