We describe here diagnosis treatment of a case that rose from the sternocleidomastoid muscle and was treated without surgical excision. A 56-year-old man presented with a rapidly growing, painless and not well-circumscribed mass at the right side of the neck. We diagnosed this tumor as proliferative myositis (PM) based on the typical findings from ultrasonography, computed tomography, and core-needle biopsy, and treated it without surgical excision. Herein we report a successful diagnosis and treatment process of a case of PM, which was followed-up with ultrasonography.

A 75-year-old man presented very late with a huge sternal mass that measured 91 × 84 mm on computed tomography. A core needle biopsy revealed atypical cartilage tissue, suggesting chondrosarcoma. The mass was resected and the defect was reconstructed with bone cement, Prolene mesh, and a muscle flap.

A 37-year-old Burmese woman presented with an incidentally found retroperitoneal fat-containing tumor. The tumor was 9 cm in the longest diameter, surrounding the right kidney, and composed of homogenous adipose tissue with thickened septum-like structures and spotty nonadipose structures, which were enhanced on contrast-enhanced computed tomography and magnetic resonance imaging. The tumor did not show either a beak sign or synchronous angiomyolipoma-like lesion in the kidneys. The tumor had irregular septa, thin blood vessels, and spotty small soft-tissue nodules. The tumor did not contain any heterogeneously enhanced solid lesions suspicious for dedifferentiated liposarcomas. Based on these imaging findings, a clinical diagnosis of a well-differentiated liposarcoma was made. Under the consensus of a multidisciplinary cancer board, she was recommended to undergo core-needle biopsy to confirm the clinical diagnosis. However, she declined to undergo biopsy for financial reasons. She underwent kidney-sparing retroperitoneal tumor resection. Histopathologically, the tumor was an angiomyolipoma with positive immunostaining for HMB45 and Melan A. The present case suggests the importance of core-needle biopsy prior to surgical intervention for retroperitoneal fat-containing tumors.
