Pleural desmoid tumor: A rare site of presentation

Summary

Desmoids are a rare type of tumor with an unpredictable natural history. The annual incidence in the general population is estimated at 2.4-4.3 cases per million. This rare case is considered a diagnostic challenge. Therefore, the emergence of knowledge of CT features and other findings is an important aspect in the diagnosis. In this case study, we present a 57-year-old female patient with a 2-year history of chest pain in the right upper chest. To establish a proper diagnosis a chest X-ray was performed and showed opacities in the right hemithorax, and computed tomography revealed a solid pleural mass measuring 4.4 cm × 4 cm × 3 cm. Along with imaging results, histopathological examination and immunohistochemical analysis of an open biopsy revealed a desmoid tumor.
