A case series of rare and aggressive extra cranial malignant rhabdoid tumors.

Malignant rhabdoid tumors (MRT) are very aggressive neoplasms seen in infantile age groups. A high index of suspicion is needed for early diagnosis. They are small round cell tumors with characteristic loss of INI -1 expression. Here we present a case series of 6 rhabdoid tumors diagnosed over 2 years, of which 4 of them presented as soft tissue swelling neck and chest wall. All of them had a very short duration of presentation and despite timely diagnosis, 4 of them progressed while on treatment and resulted in mortality.
