ABSTRACT
Mycobacterium fortuitum is associated with skin and soft-tissue infections, yet isolated liver involvement is rare. A 67-year-old asymptomatic man was referred for endoscopic ultrasound (EUS) to evaluate a gastric lesion and an incidental liver mass. EUS revealed a heterogeneous liver mass that was sampled. Pathology revealed necrotic granulomatous inflammation and positive acid-fast bacilli stain with M. fortuitum deoxyribonucleic acid. Levofloxacin plus trimethoprim and sulfamethoxazole for 3 months were used for complete resolution of liver lesion. Isolated nontuberculous liver involvement is uncommon. We report the first case of a liver mass caused by M. fortuitum diagnosed by EUS-fine needle aspiration.
ABSTRACT
RESUMEN El pseudotumor inflamatorio hepático es una lesión muy infrecuente, sin una etiología ni patogenia claras. Su diagnóstico preoperatorio no es habitual pero, en caso de realizarse, puede evitar la cirugía. Presentamos el caso de un paciente joven, con antecedente de lupus cutáneo que, tras debutar con una pancreatitis aguda, presenta episodios de colangitis y cuyos hallazgos radiológicos no permiten descartar la presencia de un colangiocarcinoma, por lo que se realiza hepatectomía izquierda, siendo el diagnóstico histológico final de pseudotumor inflamatorio hepático.
ABSTRACT Inflammatory pseudotumors of the liver are rare and lack clear etiology and pathogenesis. The preoperative diagnosis is seldom made but it avoids unnecessary surgery. We report the case of a young male patient with a history of cutaneous lupus and episodes cholangitis after an acute pancreatitis. As the imaging tests could not rule out cholangiocarcinoma, a left liver resection was performed, and the final histologic diagnosis was inflammatory pseudotumor of the liver.

Se realizó un estudio descriptivo y transversal de 87 pacientes diagnosticados con masa hepática sólida, los cuales fueron atendidos en el hospital gambiano de Farafenni, de enero a diciembre del 2008, con vistas a caracterizarles desde los puntos de vista clinicoepidemiológico y ecográfico. Se analizaron variables sociodemográficas y clínicas. Se tuvieron en cuenta criterios de inclusión y exclusión. Además, se empleó el porcentaje como medida de resumen. En la serie predominaron el sexo masculino, el grupo etario de 45-59 años, la hepatitis viral B como el antecedente patológico, el dolor abdominal como la manifestación clínica más frecuente y desde el punto de vista ecográfico los nódulos múltiples y la infiltración difusa.
A descriptive and cross sectional study was carried out in 87 patients diagnosed with solid liver mass, who were attended in the hospital of Farafenni, Gambia, from January to December 2008, in order to characterize them from clinical, epidemiological and ultrasonic points of view. Sociodemographic and clinical variates were analyzed. Inclusion and exclusion criteria were considered. Also, the percentage as summary measure was used. Male sex, age group of 45-59 years, viral hepatitis B as medical history, and abdominal pain as the most frequent clinical manifestation and multiple nodes and diffuse infiltration as ultrasonic findings prevailed in the series.
