Key result
A 33-year-old man was diagnosed with primary Ewing sarcoma of the lung, an extremely uncommon extraskeletal primary source, following postsurgical histological examination.
Case Report (n=1)
Highlights the rare presentation of primary Ewing sarcoma in the lung parenchyma and the need to consider unusual possibilities for unresolved clinical and radiological abnormalities.
Raises awareness for rare primary pulmonary Ewing sarcoma in young adults; extends the documented spectrum of extraskeletal sites but leaves management unchanged.
Ewing sarcoma usually develops in the second decade of life as a primary osseous malignancy. An extraskeletal primary source of this condition from the lung parenchyma is extremely uncommon. We report the case of a 33-year old man with primary Ewing sarcoma of the lung diagnosed upon postsurgical histological examination. Initially presenting with unilateral pleural effusion, our patient underwent various investigations before final diagnosis. This case report reviews the available literature of similarly reported cases and discusses the current developments on managing this rare and aggressive disease. As a supplementary learning point, this case reminds us always to consider unusual possibilities and seek further sub-specialist opinion when presented with unresolved clinical and radiological abnormalities that require further exploring beyond the primary line of investigations and treatment.
