In our case, the distal acinar emphysema represents a histologic pattern which correlates with MFS [10] and an underlying history of SP.
It is however essential to remember that distal acinar emphysema is not a distinguishing feature of MFS and may be seen in other disease processes, notably in tall, thin males with SP.
