In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue. This abnormal tissue will never function as normal lung tissue. The underlying cause for CPAM is not known. It occurs in approximately 1 in every 30000 pregnancies. The association between CPAM and malignancy has been well documented. There is a small risk(0.7%) of malignant transformation within the cyst. So early diagnosis and surgical resection is important to prevent the grave complications. Herein, we are reporting two interesting cases of CPAM and one belonged to Type Ⅱ and other belonged to Type Ⅲ of Stocker's classification.展开更多

It is highly aggressive soft tissue tumor with higher local recurrence rate. MTT has poor prognosis than MPNST. MTT seems to be more aggressive in patients with neurofibromatosis(NF-1). We herein, reporting an interesting case of 55 years male with multiple neurofibromas all over the body since 30 years and multiple café-au-lait spots, diagnosed as NF-1. Since 6 years, he had an enlarged mass in left thigh. Wide excision of mass was done. On histopathological examination revealed the diagnosis of MTT and diagnosis of which was confirmed on immunohistochemistry.展开更多
