Myxoid malignant fibrous histiocytoma is a rare type of pediatric non-rhabdomyosarcoma soft-tissue sarcoma. The case of a 5-year-old girl is presented, highlighting the potential for multiple pitfalls and aberrant differential diagnoses that need to be identified for successful treatment of pediatric myxofibrosarcomas. An awareness of these tumors and a call for standardized postsurgical treatment protocols is necessary in order to successfully treat children with this disease.

Spindle cell lipoma (SCL) is a benign adipocytic tumor usually found in the subcutis of the posterior neck, upper back, and shoulder, predominantly in middle-aged males. This case report describes an atypical presentation of SCL in a 26-year-old male with a history of malignant melanoma. The patient presented with an erythematous plaque with central hyperpigmentation on the right upper arm, an uncommon location and presentation for SCL.

Inflammatory myofibroblastic tumors (IMTs) are rare mesenchymal neoplasms characterized by spindle-cell morphology with accompanying inflammatory infiltrates. Originally described in 1939, these tumors can arise in various anatomic locations, with the urinary bladder being a rare site of occurrence but the most common within the genitourinary tract. IMTs typically present as polypoid masses or firm submucosal nodules, often with painless hematuria in bladder cases.
View Article and Find Full Text PDFLiposarcomas are the most common soft tissue sarcoma primarily originating in deep soft tissues and the retroperitoneum. Sarcoma classification includes atypical lipomatous tumor/well-differentiated liposarcoma (WDL) and dedifferentiated liposarcoma (DDL), myxoid liposarcoma, and pleomorphic liposarcoma. DDL is most prevalent in the retroperitoneum and often has two distinct components, a well-differentiated lipomatous component and a dedifferentiated nonlipomatous component that could be morphologically similar to malignant fibrous histiocytoma (MFH) or fibrosarcoma.

Background: Non-meningothelial intracranial mesenchymal tumors are a heterogeneous group of central nervous system neoplasms endowed with great variability clinically and histologically. For this precise reason, significant difficulties exist in specifically cataloguing tumor entities with such distant characteristics and such uncertain clinical course.
Case Description: In an attempt to increase the knowledge inherent in this type of central nervous system lesions we report a case of a rare and unusual myxoid mesenchymal tumor of difficult anatomopathological classification characterized by rapid progression and optimal therapeutic response after combined surgical and radiotherapy treatment, with histo-molecular definition and DNA methylation profile.
