We describe a previously healthy 14-year-old girl who presented with chronic productive cough. Chest computed tomography (CT) revealed a right lower mass with involvement of the parietal pleura, chest wall, diaphragm, liver and costovertebral junction. Thoracostomy biopsy was performed due to suspicion of low-grade mucosa-associated lymphoid tissue lymphoma. However, histological analysis revealed a pulmonary botryomycosis. The right lower lung mass completely resolved after 3 months of antibiotics treatment. This case emphasizes that primary pulmonary botryomycosis with extensive contiguous involvement may not be distinguishable from lung cancer, lymphoma or fungal infection on chest CT.Diagnosis, differential; Gram-positive bacterial infection; Liver; Lymphoma, mucosa-associated lymphoid tissue[SDGs]SDG3albumin; alpha 2 globulin; amoxicillin; ampicillin; antibiotic agent; beta globulin; C reactive protein; CD2 antigen; CD20 antigen; CD3 antigen; clavulanic acid; leukosialin; sulbactam; sulfur; adolescent; article; case report; chronic disease; computer assisted tomography; coughing; dyspnea; female; histopathology; hospital admission; human; human tissue; hypergammaglobulinemia; laboratory test; lung cyst; lung infection; lymphadenopathy; lymphocytosis; mucosa associated lymphoid tissue lymphoma; physical examination; pleura effusion; pneumonia; thorax drainage; thorax radiography; treatment outcome; Botrytis; diaphragm; differential diagnosis; isolation and purification; liver; lung mycosis; lung tumor; microbiology; mucosa associated lymphoid tissue lymphoma; pleura; thorax wall; vertebra; Adolescent; Botrytis; Diagnosis, Differential; Diaphragm; Female; Humans; Liver; Lung Diseases, Fungal; Lung Neoplasms; Lymphoma, Mucosa-Associated Lymphoid Tissue; Pleura; Thoracic Vertebrae; Thoracic Walljournal article163853772-s2.0-33644875476
