INTRODUCTION It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare...

We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst. To the best of our knowledge, this appears to be the third case of a malignant fibrous histiocytoma and a squamous cell carcinoma developing from a mature cystic teratoma. Mali...

In this report, a case of malignant fibrous histiocytoma involving skin, lungs, kidneys, pancreas and mediastinal lymph node was described. Microscopically, the tumor classified as storiform-pleomorphic type malignant fibrous histiocytoma.

Benign fibrous histiocytoma (FH) is a benign tumor composed of fibroblasts and histiocytes in varying proportions. This tumor is usually found in adult extremities but rarely occurs in deep soft tissues of the oral cavity. As it is difficult to diagnose with physical and radiologic exams, deep benign FH can only be diagnosed by histopathology. We report a case of a 36-year-old female patient wh...

Fibroepithelial stromal polyp (FSP) is a benign lesion that can occur at various sites, including the lower female genital tract. In rare cases, however, it may exhibit hypercellularity, bizarre cytomorphological features, and atypical mitoses resulting in an overdiagnosis as a malignant tumor despite its benign clinical course. Recently, we experienced one case of a 30-year-old pregnant woman ...

Here we report a 38 year old male who was evaluated for splenomegaly and diagnosed to have malignant fibrous histiocytoma of spleen, which was confirmed histopathologically. Very few cases of MFH have been reported.
