RESUMO
In order to describe the clinical and epidemiological characteristics of paracoccidioidomycosis, a descriptive study of all the cases diagnosed by the Clinical Microbiology Service at Dr. Julio C. Perrando hospital in the city of Resistencia (Chaco Province, Argentina) was conducted. Between 2011 and 2014, 46 cases were detected. In the period 2013-2014, an almost 4-fold increase in the incidence rate was detected. The chronic form of the disease was predominant with an average age of 53 years. Serological tests in 39 out of 46 patients were performed. In 15 of 39 patients, serological tests were the only diagnostic tool while in 4 patients with a microbiological diagnosis serological tests were non-reactive. In patients from endemic areas with non-specific infectious syndrome it is important to include paracoccidioidomycosis in the differential diagnosis and to apply all available diagnostic tools to reach a timely diagnosis and to reduce the long-term sequelae and their socio-economic impact.

In the second part of this review on the deep mycoses, we describe the main systemic mycoses-paracoccidioidomycosis, coccidioidomycosis, histoplasmosis, mucormycosis, and cryptococcosis-and their cutaneous manifestations. Skin lesions are only occasionally seen in deep systemic mycoses either directly, when the skin is the route of entry for the fungus, or indirectly, when the infection has spread from a deeper focus. These cutaneous signs are often the only clue to the presence of a potentially fatal infection. As with the subcutaneous mycoses, early diagnosis and treatment is important, but in this case, even more so.

OBJECTIVE: To analyse hospital morbidity records due to paracoccidioidomycosis in Brazil, including its nationwide distribution in time and space, as well as key epidemiological and sociodemographic characteristics. METHODS: Descriptive analysis of hospital morbidity records due to paracoccidioidomycosis covering the period January 1998 to December 2006. Hospital records were obtained from the Hospital Information System of the Brazilian Unified Health System (SIH/SUS). RESULTS: There were 6732 hospitalisations (82% male) due to paracoccidioidomycosis in the period, representing 4.3 per 1.0 million inhabitants. Admissions due to this mycosis were recorded in 27% of the 5560 Brazilian municipalities, covering 35% of the country. Ten municipalities concentrated 52% of all admissions. The temporal distribution of admissions for paracoccidioidomycosis showed a slight increase. The geographical analysis showed two distinct patterns of the disease: (i) traditional areas of southern and south-eastern regions, covering 60% of admissions, and (ii) a second pattern in northern Brazil revealed a transverse band of higher concentration with about 27% of admissions, particularly along the southern border of the Amazon region. CONCLUSION: This first nationwide analysis of hospitalisation due to paracoccidioidomycosis in Brazil shows that it is the most prevalent systemic mycosis in Brazil. Despite its importance, there are major deficits in its proper registry, diagnostics and treatment. The particular epidemiological and medical challenges of paracoccidioidomycosis will not be met while the disease continues to be perceived as an isolated infectious entity restricted to a few faraway regions of the globe.
RESUMO
OBJECTIVE: To describe magnetic resonance imaging (MRI) findings in musculoskeletal paracoccidioidomycosis (PCM). METHODS: Retrospective case series study after IRB approval. Two musculoskeletal radiologists reviewed in consensus the MRI findings of 11 patients with microbiologically and/or pathologically proven osteoarticular PCM. The MRI evaluation included discrimination of abnormalities in joints, bones and soft tissues. RESULTS: Mean age of patients was 29 years (10-55 years), eight men and three women. Musculoskeletal involvement was the only or the primary presentation of the disease in seven patients (63%). Osteomyelitis was the most common presentation, with seven cases (63%). Primary arthritis was found in one patient (9%). Isolated extra-articular soft tissue PCM was found in three patients: myositis (2) and subcutaneous infection (1). All cases showed regions with signal intensity higher than or similar to the signal of muscle on T1-weighted images. Penumbra sign was present in five cases (45%). T2-weighted images showed reactive soft tissue oedema in eight cases (72%). Post-gadolinium images showed peripheral (8/9) or heterogeneous (1/9) enhancement. Synovial enhancement was present in all cases of joint involvement (6/6). Lipomatosis arborescens was documented in one case of chronic knee involvement. CONCLUSION: To our knowledge, this is the first case series describing MRI findings of musculoskeletal PCM. Musculoskeletal involvement was the primary presentation of the disease in most cases, and therefore, neoplasms were initially in the differential diagnosis. Osteomyelitis was the most common presentation, often with secondary involvement of joint and or soft tissue.

BACKGROUND: Paracoccidioidomycosis is a neglected tropical disease caused by fungi of the genus Paracoccidioides. A wide range of symptoms is related to the disease; however, lungs and skin are the sites predominantly affected. The disease is mostly seen in people living in rural areas in Latin America. CASE REPORT: We present a pediatric case of severe disseminated paracoccidioidomycosis that slowly responded to the antifungal treatment. Within three months, symptoms evolved into hepatosplenomegaly, necrotic cervical and abdominal lymph nodes, and splenic abscess. Clinical response to amphotericin B deoxycholate and itraconazole was slow, resulting in pleural and peritoneal cavity effusions, heart failure and shock. Amphotericin B deoxycholate was replaced by the liposomal formulation, with no response. Subsequently, prednisone was added to the treatment, which led to improvement in the clinical response. Serological Paracoccidioides antibody titers were atypical, with very low titers in the critical phase and significant increase during the convalescence phase. The infection was finally cleared up with amphotericin B deoxycholate, liposomal amphotericin B and the use of corticosteroids. Paracoccidioidomycosis serology was non-reactive two years post-discharge. CONCLUSIONS: Due to the intense inflammatory response triggered by Paracoccidioides cells, giving low-dose prednisone for a short period of time modulated the inflammatory response and supported antifungal treatment.
RESUMO
BACKGROUND: Paracoccidioidomycosis is a systemic infection caused by the fungus Paracoccidioides. It may present in two forms: an acute/subacute form, whose most frequent manifestations include weight loss, fever, anemia, and adenopathy, and a chronic condition with mainly respiratory symptoms. Digestive symptoms, although they may occur, are not frequently reported. Paracoccidioidomycosis usually affects adult male agricultural workers; thus, its presentation in children is rare. CASE REPORT: We describe the case of a 9-year-old male patient diagnosed with paracoccidioidomycosis, who showed abdominal pain and diarrhea as initial manifestations of the disease. CONCLUSIONS: This case is reported not only because of the age of presentation but also due to the existence of digestive symptoms from the onset of the disease, both infrequently reported in the literature.
INTRODUCCIÓN: La paracoccidioidomicosis es una infección sistémica producida por el hongo Paracoccidioides. Se puede presentar de dos formasuna forma aguda/subaguda, cuyas manifestaciones más frecuentes incluyen pérdida de peso, fiebre, anemia y adenopatías, y una forma crónica con manifestaciones principalmente respiratorias. Las manifestaciones digestivas, aunque pueden presentarse, no se reportan frecuentemente. La paracoccidioidomicosis afecta usualmente a varones adultos que trabajan en labores agrícolas, por lo que su presentación en niños es poco frecuente. CASO CLÍNICO: Se describe el caso de un paciente de sexo masculino de 9 años de edad con diagnóstico de paracoccidioidomicosis, con dolor abdominal y diarrea como manifestaciones iniciales de la enfermedad. CONCLUSIONES: Se reporta este caso, no solamente por la edad de presentación, sino también por la existencia de síntomas digestivos desde el inicio de la enfermedad, ambos reportados en forma infrecuente en la literatura.

BACKGROUND: Paracoccidioidomycosis (PCM) is an endemic disease in Latin America. In immunocompetent hosts, PCM occurs in two main clinical forms: acute and chronic. However, in HIV-infected patients PCM may show up simultaneous manifestations of acute and chronic forms. CASE REPORT: We present the case of a patient diagnosed with HIV who had disseminated skin lesions and generalized lymphadenopathy, as well as respiratory and central nervous system involvement. The PCM diagnosis was confirmed by direct KOH examination, double immunodiffusion and the isolation of the fungus in samples of an abscess in the subcostal region. The isolate was identified as Paracoccidioides brasiliensis S1 by species-specific PCR using primers for protein-coding gene GP43 (exon 2) followed by PCR-RFLP of the alpha-tubulin gene. CONCLUSIONS: There are few data in literature reporting species-specific molecular identification of Paracoccidioides in HIV/PCM patients. Therefore, this case report may contribute to improve the knowledge about this severe disease, its causative cryptic species, and its consequences to patients.

BACKGROUND: Pulmonary mycoses resemble clinically and radiologically chronic pulmonary tuberculosis. Studies describing the prevalence, etiology and clinical features of pulmonary mycosis are of crucial importance in the Brazilian Amazon. AIMS: To estimate the frequency of pulmonary mycoses in smear-negative tuberculosis patients; to describe their demographic, epidemiological, and clinical characteristics; and to evaluate diagnostic methods. METHODS: A cross-sectional study was conducted at two tuberculosis reference institutions in Amazonas, Brazil. We included 213 patients and collected clinical data, blood and induced sputum to perform serological, direct microscopy, microbiologic culture and PCR-based assays to identify infections caused by Aspergillus fumigatus, Paracoccidioides brasiliensis, Histoplasma capsulatum, Cryptococcus, and HIV. Chest computed tomography was also performed. RESULTS: Pulmonary mycoses were diagnosed in 7% (15/213) of the cases, comprising ten aspergillosis cases, three cases of paracoccidioidomycosis and one case each of histoplasmosis and cryptococcosis. Among the patients with pulmonary mycoses, 86.7% were former tuberculosis patients. The most significant clinical characteristics associated with pulmonary mycoses were cavity-shaped lung injuries, prolonged chronic cough and hemoptysis. CONCLUSIONS: Our study confirmed the high prevalence of pulmonary mycoses in smear-negative tuberculosis patients in the Brazilian Amazon.

Introducción: la paracoccidioidomicosis es una micosis endémica en áreas tropicales de Suramérica y Centroamérica. 50 % de los pacientes tiene afectación de las membranas mucosas, y la mucosa laríngea se afecta en 22 %-43 % de los casos. Caso clínico: se presenta un caso ilustrativo de un paciente con paracoccidioidomicosis y afectación de la mucosa oral y laríngea con curso clínico sugestivo de tuberculosis diseminada. Discusión: el compromiso mucoso se presenta en 50 % pacientes con paracoccidioidomicosis, mientras que la afectación laríngea se da en 22 %-43 % de los pacientes. En la mayoría de los casos, las lesiones laríngeas se observan como masas granulomatosas con una superficie hemorrágica y se asocian con disfonía, por lo que son difíciles de diferenciar de una tuberculosis laríngea. Conclusión: la afectación laríngea en pacientes con paracoccidioidomicosis es frecuente y tiene curso clínico similar al de la tuberculosis, e implica un reto diagnóstico.
Introduction: Paracoccidioidomycosis is a mycosis endemic in tropical areas of South America and Central America. 50% of patients have mucous membrane in-volvement and the laryngeal mucosa is affected in 22-43% of cases. Case report: We present an illustrative case of a patient with Paracoccidioidomycosis with in-volvement of the oral and laryngeal mucosa with a clinical course suggestive of disseminated tuberculosis. Discussion: Mucosal involvement occurs in half of the patients with Paracoccidioidomycosis, while laryngeal involvement occurs in 22-43% of patients. In most cases, laryngeal lesions are observed as granulomatous masses with a hemorrhagic surface and are associated with dysphonia, making them difficult to differentiate from laryngeal tuberculosis. Conclusion: Laryngeal invol-vement in patients with Paracoccidioidomycosis is frequent and has a clinical course similar to that of tuberculosis, implying a diagnostic challenge.

Introduction. The existing methods for Paracoccidioides spp. antigen production are problematic in terms of standardization, specificity, stability, repeatability, and reproducibility. Objective. To optimize the methodology for Paracoccidioides spp. antigen production and evaluate its applicability in paracoccidioidomycosis immunodiagnosis. Materials and methods. The antigens were obtained from Paracoccidioides lutzii isolates (01, 66, and 8334), Paracoccidioides brasiliensis sensu stricto (113), and Paracoccidioides restripiensis (B-339). These fungi were grown at 36 °C ± 1 °C, on modified Fava-Netto agar, according to Freitas et al. (2018). Paracoccidioides lutzii antigens were obtained after 5, 10, and 20 days of culture, whereas P. brasiliensis and P. restripiensis antigens were obtained after 10 days. Antigens were evaluated in natura, 10 and 20 times concentrated. Antigenic capacity was evaluated using a double immunodiffusion assay against serum samples from patients with paracoccidioidomycosis, histoplasmosis, and aspergillosis, and random blood donors. Results. Cross-reactivity between Paracoccidioides spp. antigens was observed when P. brasiliensis, P. restrepiensis antigens, and P. lutzii antigens were evaluated with the polyclonal antibodies against P. lutzii and P. brasiliensis, respectively. No cross-reactivity was obtained for polyclonal antibodies against Histoplasma capsulatum, Aspergillus fumigatus, and random blood donors. The proposed protocol allowed stable, repeatable, and reproducible genus-specific antigen production at a low cost and in a short cultivation time. Conclusion. The proposed protocol allowed us to obtain genus-specific antigens that can be developed and reproduced in all laboratories in Brazil and South America, where paracoccidioidomycosis is a neglected disease, contributing to an early diagnosis, especially in endemic regions, regardless of the species.
Introducción. Los métodos existentes para la producción de los antígenos de Paracoccidioides spp. son problemáticos en su estandarización, especificidad, estabilidad, repetibilidad y reproducibilidad. Objetivo. Optimizar la metodología para la producción de antígenos de Paracoccidioides spp. y evaluar su aplicabilidad en el inmunodiagnóstico de la paracoccidioidomicosis. Materiales y métodos. Los antígenos se obtuvieron de aislamientos de P. lutzii (01, 66 y 8334), P. brasiliensis sensu stricto (113) y P. restripiensis (B-339). Estos hongos se cultivaron a 36 °C ± 1 °C en agar Fava-Netto modificado, según Freitas et al. (2018). Los antígenos de P. lutzii se obtuvieron a los 5, 10 y 20 días de cultivo y los antígenos de P. brasiliensis y P. restripiensis se obtuvieron a los 10 días. Los antígenos se evaluaron in natura, concentrados 10 y 20 veces. La capacidad antigénica se evaluó mediante un ensayo de inmunodifusión doble con muestras de suero de pacientes con paracoccidioidomicosis, histoplasmosis, aspergilosis y donantes de sangre aleatorios. Resultados. Se observó reacción cruzada con Paracoccidioides spp. cuando se evaluaron los antígenos de P. brasiliensis, P. restrepiensis y P. lutzii frente a los anticuerpos policlonales contra P. lutzii y P. brasiliensis, respectivamente. No hubo reactividad cruzada con los anticuerpos policlonales contra Histoplasma capsulatum y Aspergillus fumigatus, ni contra los donantes de sangre aleatorios. El protocolo propuesto permitió la producción estable, repetible y reproducible de antígenos dirigidos de un género específico (Paracoccidiodes) en un tiempo corto de cultivo y a un menor costo. Conclusión. El protocolo propuesto permitió obtener antígenos específicos de un género, que pueden ser desarrollados y reproducidos en todos los laboratorios de Antígenos de Paracoccidioides spp.: protocolo rápido Brasil y Surámerica donde la paracoccidioidomicosis es una enfermedad endémica y desatendida. Estos antígenos pueden contribuir al diagnóstico precoz de la infección, independientemente de la especie.

La Paracoccidiomicosis es una infección endémica. Junto con la histoplasmosis, son las infecciones micóticas más frecuentes en Latinoamérica. Esta micosis puede ser de afección local o sistémica, con un marcado trofismo por los pulmones, órganos linfoides, hígado, glándulas suprarrenales, piel y mucosa. Presentamos el caso de un varón adulto, consumidor crónico de corticoides, que desarrolla una paracoccidiomicosis sistémica con afección pulmonar y de glándulas suprarrenales con buena repuesta a la terapéutica antifúngica.
Paracoccidiomycosis is an endemic infection, together with histoplasmosis, they are the most frequent fungal infections in Latin America. This mycosis can be of local or systemic affection, with a marked trophism by the lungs, lymphoid organs, liver, adrenal glands, skin and mucosa. We present the case of an adult male, chronic steroid user, who develops systemic paracoccidiomycosis with pulmonary and adrenal gland involvement with good response to antifungal therapy.
RESUMO
Introducción. La paracoccidioidomicosis es una micosis sistémica y endémica en Latinoamérica. El cambio climático y el movimiento migratorio del huésped enfatizan la necesidad de optimizar el diagnóstico de esta infección. Objetivo. Evaluar la implementación de la detección de ADN de Paracoccidioides spp. al diagnóstico micológico de pacientes con sospecha de paracoccidioidomicosis. Materiales y métodos. Estudio retrospectivo con datos de laboratorio de pacientes con sospecha de paracoccidioidomicosis en un hospital de área no endémica. Resultados. Se analizaron los resultados de las muestras de 19 pacientes con sospecha clínica de paracoccidioidomicosis. El 90 % de los pacientes había nacido o visitado un área endémica de esta micosis en Latinoamérica. En 14 pacientes varones adultos se confirmó paracoccidioidomicosis por diagnóstico convencional. El examen directo fue positivo en 12 pacientes con enfermedad comprobada y en 4 de ellos se obtuvo crecimiento del hongo. Se detectaron anticuerpos contra Paracoccidioides spp. en ocho pacientes con la enfermedad. Se realizó PCR anidada con muestras de 14 pacientes para detectar ADN de Paracoccidioides spp. En 9 de los 10 pacientes con diagnóstico convencional de paracoccidioidomicosis se obtuvo una prueba de PCR positiva. Conclusiones. La implementación de técnicas moleculares para detectar ADN de Paracoccidioides spp. complementa el diagnóstico convencional de paracoccidioidomicosis y permite instaurar el tratamiento antifúngico, sobre todo en los casos clínicos donde no se observa la presencia del hongo en las muestras clínicas. La migración actual de poblaciones humanas dificulta el diagnóstico de paracoccidioidiomicosis y otras infecciones endémicas, por lo que se requiere optimizar el diagnostico micológico en los laboratorios clínicos para tratar pacientes con este tipo micosis desatendida.
Introduction. Paracoccidioidomycosis is a systemic mycosis endemic in Latin America. Climate change and host migration emphasize the need to optimize this infection diagnosis. Objective. To evaluate the implementation of Paracoccidioides spp. DNA detection in the mycological diagnosis of patients with suspected paracoccidioidomycosis. Materials and methods. It is a retrospective study with laboratory data from patients with clinical suspicion of paracoccidioidomycosis, who consulted a university hospital from a non-endemic area. Results. We analyzed the laboratory results of samples from 19 patients with suspected paracoccidioidomycosis. Seventeen out of 19 patients were born in or had visited an endemic area in Latin America. Fourteen adult male patients were confirmed to have paracoccidioidomycosis by conventional diagnosis: the direct examination was positive in 12 samples while fungal growth was found only in 4. Anti-Paracoccidioides spp. antibodies were detected in 10 patients, 8 of them with proven paracoccidioidomycosis. Nested PCR for Paracoccidioides spp. detection was performed on clinical samples from 14 patients, and positive results were obtained for 9 out of 10 patients with the conventional diagnosis of paracoccidioidomycosis. Conclusions. The incorporation of molecular techniques to detect Paracoccidioides spp. DNA complements the conventional diagnosis of paracoccidioidomycosis. This tool allows the prescription of antifungal treatment in those cases where the fungus is not observed in the clinical samples. Current human migrations difficult the mycological diagnosis of paracoccidioidomycosis and other fungal infections. For this reason, it is necessary to improve mycological diagnosis in clinical laboratories to adequately treat patients with this neglected mycosis.

RESUMO
La paracoccidioidomicosis es una micosis sistémica endémica en Latinoamérica. La presentación más frecuente compromete crónicamente los pulmones, la piel y las mucosas. Al inicio, este paciente presentó, por varios años, una lesión única en la mucosa oral que, en ausencia de otros síntomas, se relacionó con una neoplasia maligna, específicamente con un carcinoma escamocelular. La diferenciación entre los dos diagnósticos se hace mediante un examen directo, un estudio histopatológico y cultivos iniciales y subsecuentes. Sin embargo, tales estudios no fueron concluyentes. Después de varias consultas y pruebas, con los resultados del examen directo, la inmunodifusión y la PCR en tiempo real se confirmó el diagnóstico de paracoccidioidomicosis crónica multifocal. Este caso alerta sobre la ausencia de sospecha clínica de micosis endémicas, dada la presencia de lesiones mucocutaneas que pueden ser producidas por hongos como Paracoccidioides spp, y la importancia de considerarlas entre los diagnósticos diferenciales.
Paracoccidioidomycosis is a systemic mycosis endemic in Latin America. The most frequent form involves a chronic compromise of the lungs, skin, and mucosa. The patient started with a single oral lesion that lasted for several years. The absence of other symptoms pointed out a possible malignant neoplasm, specifically a squamous cell carcinoma. Differentiation between both diagnoses-fungal infection and carcinoma-depends on the results of the direct examination, the histopathological study, and the initial and subsequent cultures. However, in this case, those findings were not conclusive. The coexistence of both diagnoses is frequent and increases the diagnostic challenge. After several consultations and tests, direct examination, immunodiffusion and real-time PCR findings the multifocal chronic paracoccidioidomycosis diagnosis was confirmed. This case warns about a systematical absence of clinical suspicion of endemic mycoses before the appereance of mucocutaneous lesions, which can be produced by fungi like Paracoccidioides spp, and the importance of considering those mycoses among the differential diagnoses.

Resumen La Paracoccidioidomicosis (PCM) es una infección micótica endémica en Latinoamérica que se caracteriza por compromiso multiorgánico. El diagnóstico tardío y la diseminación sistémica favorecen complicaciones como falla respiratoria e insuficiencia suprarrenal que condicionan el desenlace del paciente. Se presenta el caso de un paciente de 51 años de edad, procedente de la costa pacífica colombiana, inmunocompetente con PCM diseminada a sistema nervioso central (SNC), pulmones y glándulas suprarrenales con debut clínico de síndrome neurológico. Durante estancia hospitalaria presenta pico febril, colapso hemodinámico, aci dosis metabólica severa e hiperlactatemia. Se hemocultivó e inició tratamiento antimicrobiano de amplio espectro con piperacilina-tazobactam (4.5 gr/IV cada 8 horas), vancomicina (15 mg/kg) más anfotericina B desoxicolato (1 mg/kg/dia) y se trasladó a unidad de cuidado intensivo. En la muestras de tejido suprarrenal se identificaron levaduras multigemantes de Paracoccidioides spp e inflamacion crónica granulomatosa. A los seis días posteriores a su ingreso, el paciente continuó con deterioro hemodinámico, desequilibrio electrolítico, shock séptico e insuficiencia suprarrenal que conllevó a su deceso a pesar de las medidas terapéuticas establecidas. Se intenta exponer el desafío que representa el diagnóstico de PCM sistémica y promover su sospecha clínica para poder identificar la enfermedad de forma oportuna y evitar complicaciones que conduzcan a un desenlace fulminante.
Abstract Paracoccidioidomycosis (PCM) is an endemic fungal infection in Latin America characterized by multi-organ involvement. Late diagnosis and systemic dissemina tion favor complications such as respiratory failure and adrenal insufficiency, which determine the outcome of the patient. We present the case of a 51-year-old patient from the Colombian Pacific coast, immunocompetent with PCM spread to the central nervous system (CNS), lungs, and adrenal glands with a clinical debut of the neurological syndrome. During a hospital stay, he presented fever peak, hemodynamic collapse, severe metabolic acidosis, and hyperlactatemia. Blood culture and began broad-spectrum antimicrobial treatment with piperacillin-tazobactam (4.5 gr / IV every 8 hours), vancomycin (15 mg/kg) plus amphotericin B deoxycholate (1 mg/kg/day) and was transferred to the intensive care unit. Paracoccidioides spp multigene yeasts and chronic granulomatous inflammation were identified in adrenal tissue samples. Six days after admission, the patient continued with hemodynamic deterioration, electrolyte imbalance, septic shock, and adrenal insufficiency that led to death despite the established therapeutic measures. The aim is to expose the challenge posed by the diagnosis of systemic PCM and promote its clinical suspicion to identify the disease promptly and avoid complications that lead to a fulminant outcome.
RESUMO
Resumen La paracoccidioidomicosis es una infección fúngica endémica de América del Sur, que afecta predominantemente a los hombres y, según su campo laboral, granjeros y agricultores. Es ocasionada por la aspiración del hongo en su forma micelar y debuta en tres formas de presentación: aguda, subaguda y crónica; esta última es más frecuente en adultos, cuyo tratamiento dependerá de los azoles, anfotericina B y sulfonamidas. El presente caso trata de un hombre de 57 años, colombiano, agricultor, sin antecedentes patológicos, quien presentaba dos meses de disfagia para sólidos que progresó a líquidos, sialorrea y pérdida de peso, a quien se le realizó endoscopia de vías digestivas altas y se observaron lesiones blanquecinas, por lo cual se realizó una biopsia que evidenció levaduras en múltiple gemación compatibles con paracoccidioidomicosis; a su vez, se observó en una tomografía de tórax compromiso parenquimatoso intersticial generalizado; posteriormente, recibió tratamiento con itraconazol, con el que mostró mejoría y resolución del cuadro clínico. En vista de que América del Sur es endémica de la patología descrita y puede presentarse de forma diseminada en inmunocompetentes, se debe tener en cuenta en aquellos pacientes que poseen factores de riesgo, sintomatología y hallazgos en estudios de extensión sugestivos de dicha enfermedad, dado el gran espectro de presentación de la infección, para así dar tratamiento oportuno y dirigido.
Abstract Paracoccidioidomycosis (PCM) is a fungal infection endemic to South America. It predominantly affects men, depending on their work field: farmers and agriculturists. Paracoccidioidomycosis is caused by the aspiration of the fungus in its micellar form and manifests in three conditions: acute, subacute, and chronic; the latter is more frequent in adults, whose treatment will depend on azoles, amphotericin B, and sulfonamides. This case concerns a 57-year-old Colombian man, a farmer with no pathological history who showed dysphagia for solids that progressed to liquids, sialorrhea, and weight loss for two months. He underwent upper GI endoscopy, and whitish lesions were observed; thus, he was biopsied, displaying yeasts in multiple gemmations compatible with paracoccidioidomycosis. In turn, a chest CT scan showed generalized interstitial parenchymal involvement. Subsequently, he was treated with itraconazole, showing improvement and resolution in his clinical picture. Since the pathology described is endemic in South America and can be disseminated in immunocompromised patients. Given the broad infection spectrum, consideration should be given to patients with risk factors, symptomatology, and findings in extension studies suggesting this disease to provide timely and specific treatment.
RESUMO
Abstract Background: Paracoccidioidomycosis is a systemic infection caused by the fungus Paracoccidioides. It may present in two forms: an acute/subacute form, whose most frequent manifestations include weight loss, fever, anemia, and adenopathy, and a chronic condition with mainly respiratory symptoms. Digestive symptoms, although they may occur, are not frequently reported. Paracoccidioidomycosis usually affects adult male agricultural workers; thus, its presentation in children is rare. Case report: We describe the case of a 9-year-old male patient diagnosed with paracoccidioidomycosis, who showed abdominal pain and diarrhea as initial manifestations of the disease. Conclusions: This case is reported not only because of the age of presentation but also due to the existence of digestive symptoms from the onset of the disease, both infrequently reported in the literature.
Resumen Introducción: La paracoccidioidomicosis es una infección sistémica producida por el hongo Paracoccidioides. Se puede presentar de dos formasuna forma aguda/subaguda, cuyas manifestaciones más frecuentes incluyen pérdida de peso, fiebre, anemia y adenopatías, y una forma crónica con manifestaciones principalmente respiratorias. Las manifestaciones digestivas, aunque pueden presentarse, no se reportan frecuentemente. La paracoccidioidomicosis afecta usualmente a varones adultos que trabajan en labores agrícolas, por lo que su presentación en niños es poco frecuente. Caso clínico: Se describe el caso de un paciente de sexo masculino de 9 años de edad con diagnóstico de paracoccidioidomicosis, con dolor abdominal y diarrea como manifestaciones iniciales de la enfermedad. Conclusiones: Se reporta este caso, no solamente por la edad de presentación, sino también por la existencia de síntomas digestivos desde el inicio de la enfermedad, ambos reportados en forma infrecuente en la literatura.
