5506206059	Lipoma	Benign, most common soft tissue tumor in adult Mobile, slowly enlarging Encapsulated	5
5506207598	Liposarcoma	Malignant neoplasm Deep soft tissue in the retroperitoneum Well-differentiated - good Myxoid/round cell - bad, metastasize to lung after excision	6
5506215807	Nodular Fascitis	Reactive proliferation, trauma precedes growth Fibroblastic proliferation on forearm, chest, back Painful, rapidly growing	7
5506218067	Myositis Ossificans	Reactive proliferation, trauma precedes growth Proximal muscles of extremities in young adults --> calcification	8
5506220719	Fibromatoses	Fibroblastic proliferations that infiltrate 2 types - superficial and deep	9
5506223385	Superficial Fibromatoses	Palmar Plantar Penile Well differentiated, long sweeping bundles	10
5506224307	Palmar Fibromatosis	Dupuytren's contracture Nodular thickening of palmar aponeurosis --> flexion deformities in fingers Middle aged men	11

5506471135	Fibrosarcoma	Malignant neoplasm of fibroblasts Deep tissues of thigh, knee, retroperitoneal area Slow growth Metastasize to lungs Soft, unencapsulated, w/ hemorrhage and areas of necrosis	18
5506474207	Fibrohistiocytic Tumors	Mix of fibroblasts and phagocytic lipid laden cells that resemble activated macrophages Benign or Sarcoma	19
5506477533	Benign Fibrohistiocytic Tumors	Common and small Mobile nodule in dermis or subcutaneous tissue	20
5506478762	Pleomorphic Fibrohistiocytic Tumors	Ploemorphic fibroblastic sarcoma or pleomorphic undifferentiated sarcoma Swirling pattern 30-50% will metastasize	21
