• low-grade extraskeletal osteosarcoma
  19 March

  LGESOS
  Definition: Low-grade extraskeletal osteosarcoma (LGESOS) is an extremely rare soft tissue tumor, and patients with LGESOS tend to have a better prognosis. Extraskeletal osteosarcoma (ESOS) is a rare soft tissue sarcoma, typically characterized by a bone-producing neoplasm.
  LGESOS represents an extremely rare but distinct form of extraskeletal osteosarcoma - ESOS.
  It is important to recognize this tumor, because other neoplasms and tumor-like lesions may mimic the radiological and (...)

  extraskeletal osteosarcomas (ESOS)
  Definition: Extraskeletal osteosarcoma (ESOS) is a rare soft tissue sarcoma, typically characterized by a bone-producing neoplasm.
  ESOS is a rare malignant mesenchymal neoplasm, accounting for 1% 2% of all soft tissue sarcomas.
  The tumor is located in soft tissue, without attachment to skeletal bones as determined by radiographic examination or inspection during surgery.
  The vast majority of ESOS cases published in the literature was typically (...)

• microcystic pattern
  10 March

  Definition : The microcystic pattern shows the formation of small cystic spaces. They may be empty or contain eosinophilic or basophilic material.
  Examples :
  microcystic acinic cell carcinoma http://www.webpathology.com/image.asp?n=38&Case=119 Microcystic pattern is one of the most common histologic patterns encountered in acinic cell carcinoma. The small cystic spaces may be empty or contain eosinophilic or basophilic material.
