mammary sarcomas are a heterogeneous group of malignant neoplasms that arise from the mammary stroma. primary sarcomas of the breast are extremely rare and comprise less than 0.1% of all malignant tumors of the breast. we present the case of a 56-year-old female diagnosed as stromal sarcoma, not otherwise specified - a very rare entity.

PURPOSE Recent evidence suggests that at least some sarcomas arise through aberrant differentiation of mesenchymal stromal cells (MSCs), but MSCs have never been isolated directly from human sarcoma specimens. EXPERIMENTAL DESIGN We examined human sarcoma cell lines and primary adherent cultures derived from human sarcoma surgical samples for features of MSCs. We further characterized primary...

BACKGROUND Primary and metastatic cardiac sarcomas represent a heterogeneous group of rare neoplasms with varying clinical course and diverse histogenetic line of differentiation. To date, there exist no uniform guidelines for their surgical and/or oncological treatment. METHODS We evaluated retrospectively all patients undergoing cardiac surgery for primary or secondary cardiac sarcoma in th...

primary myeloid sacrom (ms) is a rare tumor and even more rare in multiple organs with no evidence of bone marrow involvement. this report describes an unusual case of a 19-year-old male presenting scrotal ms with a history of subconjunctival ms, 5 months ago. bone marrow biopsies showed no evidence of acute leukemia. despite radiotherapy for first involvement and chemotherapy for second presen...

Central nervous system metastases as the presentation of primary cardiac sarcoma are a very rare entity, with only a few previously reported cases. Sarcomas specifically make up 10 to 20% of all primary cardiac tumors. Patients with primary cardiac tumors typically present with cardiac symptomatology that may include arrhythmias, obstruction to blood flow and valve function, or symptoms of hear...
