chloroma or granulocytic sarcoma (gs) is a malignant neoplasm of myeloid lineage that occur in a variety of anatomic sites other than the bone marrow including soft tissue, bone, lymph node, nasal fossa, skin and sometime in the orbit. in the subconjunctiva it is rarely reported. a 4-year-old girl with a history of treated acute myelogenous leukemia was referred to farabi eye hospital, tehran, ...

Clear cell sarcoma of the tendons and aponeuroses is an aggressive, rare soft tissue tumor with frequent metastases to regional lymph nodes. Sentinel lymph node biopsy, which has dramatically changed the management of melanoma, was used for clear cell sarcoma for an evaluation of popliteal and groin lymph node status. Although all isosulfan blue-stained groin lymph nodes were negative for malig...

A case report is presented describing a clear cell sarcoma of the foot (malignant melanoma of soft parts). Melanoma is most commonly associated with pigmented lesions and nodules of the skin. Clear cell sarcoma (CCS) is an anaplastic tumor consisting of cells derived from melanoblasts not forming melanin in the skin, but rather mitotic changes more consistent with malignant melanoma in subcutan...

Background: Sarcomas rarely involve body cavity fluids, accounting for less than 5% of all malignant effusions. Most existing literature describes the cytomorphologic features sarcomas in setting fine-needle aspiration and/or touch preparations targeted tissue biopsies. The objective this study was to investigate morphologic spectrum displayed by metastatic fluid specimens. Methods: pathology d...

follicular dendritic cells or dendritic reticulum cells are important components of the immune system essential for antigen presentation. malignancies arising from these cells are uncommon and the first case was reported in 1986. the most common sites of follicular dendritic cell sarcomas are lymph nodes, especially cervical, axillary and mediastinal regions, but extranodal sites including head...

Clear cell sarcoma of tendons and aponeuroses is a rare, slow-growing malignant tumor arising from the tendons and aponeuroses of the lower extremity, more often in the foot. Although it appears to be a benign tumor, the clear cell sarcoma can be a malignant sarcoma capable of local recurrences or distant metastases. Microscopically, there is a rather distinctive picture characterized by discre...
