Paracoccidioides infection is a rare entity in the USA. This dimorphic fungus is found in Central and South America and is thought to be acquired by inhalation through the soil. We report a case of Paracoccidioides brasiliensis infection presenting as a clavicular bone lesion, peripancreatic mass, and various skin lesions. A 35-year-old man with a history significant for Hodgkin lymphoma presented with a left clavicular mass that was suspected clinically and radiologically as recurrent Hodgkin lymphoma. He was not experiencing any associated symptoms and was undergoing chemotherapy treatment for his known Hodgkin disease. On CT imaging, the mass was seen as a lytic bone lesion with an overlying soft tissue mass. This was biopsied and histologically diagnosed as a Paracoccidioides brasiliensis infection with associated necrotizing granulomatous inflammation. Also found on the CT scan was an enlarging peripancreatic mass which on endoscopic biopsy had similar histologic findings. In conclusion, this report presents a rare case of Paracoccidioides brasiliensis infection mimicking recurrent Hodgkin lymphoma.

Paracoccidioides are dimorphic fungal pathogens and the etiological agents of paracoccidioidomycosis (PCM). This severe systemic mycosis is restricted to Latin America, where it has been historically endemic. Currently, PCM presents the fewest diagnostic tools available when compared to other endemic mycoses.

Paracoccidioidomycosis (PCM) is a chronic endemic mycosis in Latin America, predominantly caused by (Pb18) and (Pl01). Diagnosing PCM is challenging due to species-specific antigenic differences, therefore new biomarkers for accurate and rapid detection are needed. This study explores multiple tolerization subtractive immunization (MTSI) to generate monoclonal antibodies against rare or weakly expressed epitopes of Pb18 and Pl01, potentially improving PCM diagnosis.

We report a patient with lobomycosis caused by Paracoccidioides loboi fungi in the Andes-Amazon region of Bolivia. We examined clinical, epidemiologic, and phylogenetic data and describe potential transmission/environmental aspects of infection. Continued surveillance and identification of lobomycosis cases in South America are crucial to prevent the spread of this disease.
