Malignant small cell tumor(MSCT) of the thoracopulmonary region(Askin tumor) is
extremely rare and is seen predominantly in children and adolescents. This tumor
represents a distinct clinicopathologic entity of neuroectodermal origin, arising from the
soft tissues of the chest wall or peripheral lung. This tumor tends to recur locally, but
does not seem to disseminate widely.
The overall survival is poor.
Recently, we experienced a case of the MSCT of the thoracopulmonary region of a
12-year-old female. She was admitted because of a chest wall mass on radiographic
examination, and a complaint of intermittent chest pain. Grossly, the mass was
lobulated, round and had a solid appearance with focal necrosis and hemorrhage on the
cut surface. Histologically, small round to oval cells were arranged in compact sheets,
nests and lobular patterns with intervening fibrovascular stroma. Ultrastructurally, the
presence of loose-fitting membrane-bound neurosecretory granules was noted.
