Early or partial results. Treat as a signal, not a conclusion.
This is a 15-year retrospective descriptive study of pediatric paracoccidioidomycosis in two Argentine endemic regions that documents striking regional variation in case distribution and clinical presentation but does not establish causation or compare outcomes to a reference standard. The findings suggest distinct regional epidemiological phenotypes but remain exploratory and require prospective validation.
Retrospective descriptive regional comparison study. Infants and children aged 0 to 14 years with paracoccidioidomycosis in the northeast (NEA) and northwest (NWA) endemic regions of Argentina.. Argentina, two primary endemic regions: northeast (NEA) and northwest (NWA) areas.
71.1% of cases recorded in NWA region versus 28.9% in NEA region NWA region exhibited constant temporal occurrence; NEA showed episodic occurrence/outbreaks Hepatosplenic enlargement and abdominal compromise with GI manifestations dominated in NWA (53.1%)
No outcome data (treatment response, mortality, sequelae) or prognostic validation provided
Clinicians in Argentina and similar endemic regions should recognize distinct regional phenotypes of pediatric PCM to guide diagnostic suspicion and tailored clinical management. However, these descriptive findings alone do not yet support changes to treatment or prevention protocols and require confirmation through prospective study.
A 15-year retrospective regional descriptive study identifying epidemiological and clinical heterogeneity in pediatric paracoccidioidomycosis without a control group, comparator arm, or hypothesis testing—raises important questions about regional phenotypes but does not yet provide the evidence needed to change clinical practice.

Paracoccidioidomycosis (PCM) is a neglected systemic mycosis in Latin America. This study aims to characterize the epidemiology and clinical profiles of infant PCM cases (0 to 14 years old) over a 15-year period (2008–2023) in the two primary endemic regions of Argentina, the northeast (NEA) and the northwest (NWA) areas. Results reveal striking regional heterogeneity. Distribution showed clear disparities, 71.1% of cases were recorded in NWA, while 28.9% in the NEA area. The NWA region exhibited a constant temporal occurrence, whereas the NEA showed episodic occurrence/outbreaks potentially triggered by anthropogenic and climatic changes. Severe nutritional impairment and generalized lymphadenopathy were common clinical signs in both regions. Hepatosplenic enlargement and abdominal compromise with gastrointestinal manifestations dominated in the NWA (53.1%), while a higher prevalence of cutaneous/mucocutaneous (76.9%), pulmonary (38.4%) and osteoarticular (38.4%) manifestations characterized the clinical profiles in the NEA. These findings support the existence of distinct regional epidemiological and clinical phenotypes of pediatric PCM in Argentina. Recognizing these disparities is essential to improve clinical suspicion, diagnostic strategies, and the implementation of effective public health strategies for this severe pediatric disease.
