Aspergillus fumigatus is a significant pathogen responsible for a wide spectrum of pulmonary diseases, ranging from allergic reactions to invasive pulmonary aspergillosis, particularly among immunocompromised individuals. We describe a 62-year-old female kidney transplant recipient who presented with chest pain, a right anterior chest wall mass, cough and anorexia of 2 months' duration. Laboratory evaluation revealed elevated inflammatory markers, prompting consideration of malignancy and infection. Bronchoalveolar lavage was positive for Aspergillus galactomannan antigen, and biopsy of the chest wall mass confirmed Aspergillus infection. This case represents an unusual manifestation of Aspergillus involving soft tissue. Accurate diagnosis requires histopathological confirmation and molecular testing. This report emphasizes the importance of including fungal infections, particularly Aspergillus species, in the differential diagnosis of soft tissue masses in immunocompromised patients.
