Mutually exclusive histone 3.3 gene mutations have been recognized in chondroblastoma and giant cell tumor of bone (GCTB), which may be useful for differential diagnostic purposes in morphologically ambiguous cases. Although more than 90% of GCTBs present histone 3.3 variants exclusively in the

The Authors present a rare case of voluminous retroperitoneal tumor in a 41 years old woman. CT scan showed a solid abdominal expansive mass, with compression and displacement of the left lobe of the liver, spleen, stomach, pancreas, and left kidney. The patient underwent surgery for excision of a

BACKGROUND Liposarcoma is the most frequent type of retroperitoneal sarcomas. Dedifferentiated liposarcoma is the least common subtype and is an extremely rare tumor. METHODS We present the case of a 53-year-old male who was referred with a giant retroperitoneal mass. The patients' mass was deemed

We report a case of giant spermatic cord liposarcoma (SCL) in an 81-year-old patient, presenting with a huge scrotal mass that reached up to the knee joint. SCL is a rare tumor, and about 200 cases have been reported in the literature so far. Although 20% of liposarcomas arise in the

Multinucleated giant cells (MGCs) are a prominent histological feature of various mesenchymal neoplasms and are often considered a criterion of malignancy. Mesenchymal neoplasms with MGCs for which the cell lineage is unclear generally are referred to as giant cell sarcomas. Here we characterize the

Retroperitoneal liposarcomas are the most frequent soft tissue sarcomas and the second most frequent retroperitoneal tumours. They represent less then 0.1% of all human malignancies. Hereby we describe the treatment of our patient where of a 15-kg giant retroperitoneal liposarcoma was successfully

BACKGROUND Uterine leiomyosarcoma is a rare uterine malignancy. Most of the patients lack symptoms or present with a rapidly enlarging pelvic mass. METHODS We report on a very large leiomyosarcoma in a woman presenting with a 3 months history of rapidly growing adominal mass and fatigue. Laparotomy

Kaposi sarcoma usually occurs in immunosuppressed patients. A classic type has been reported in elderly men of Jewish and Mediterranean origin. We report a case of an elderly woman with giant cell arteritis (GCA) who developed Kaposi sarcoma while on a double blind trial for GCA with an

The pathological entity of intracranial giant cell tumor remains controversial, which has been considered a glioma (giant cell glioblastoma) by some and a sarcoma (monstrocellular sarcoma) by others. The authors present a case in which CT scan shows a wedge-shaped high density area at the left

Histiocytic sarcoma is an uncommon neoplasm of mature histiocytes with a poor clinical outcome. We report a case of a true histiocytic sarcoma with prominent and evenly distributed multinucleated giant cells that mimics a giant cell tumor of soft tissue. The tumor was located between the appendix,

We report a case of primary giant cell malignant fibrous histiocytoma (GCMFH) of the breast. A 56-year-old Japanese woman presented with a firm mass in the right breast. Mammography and ultrasonography revealed a well-circumscribed and lobulated mass in the upper outer quadrant of the right breast,

A 45-year old female had a long history of slow growing perianal tumor at the right side of her anus. Encapsulated tumour was found intraoperatively and completely excised using the Harmonic Scalpel. Tumour was well-circumscribed and relatively firm; measuring 12x6x4 cm. Histologically it was

BACKGROUND Retroperitoneal tumors are rare, mostly malignant. Locally aggressive, and more frequent in women in their 5th decade of life. Its symptoms are nonspecific, including abdominal pain and palpable mass. To diagnosis is helpful computed tomography and biopsy. It needs surgery for absolute

The term phyllodes tumour includes lesions ranging from completely benign tumours to malignant sarcomas. Clinically phyllodes tumours are smooth, rounded, and usually painless multinodular lesions indistinguishable from fibroadenomas. Percentage of phyllodes tumour classified as malignant ranges
