hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...

Background: Cytokines, chemokines, and chemokine receptors regulate the proliferation and survival of tumor cells, angiogenesis, and metastasis to other organs. This network of ligands and receptors has been used in molecular targeting of cancer. Methods: We compared the mRNA expression of CXCR3, CXCL-10, CXCR4, CXCL-12, IL-4, and IL-10 in tissues of benign and malignant ovarian tumors by qRT-P...

Ovarian fibrothecoma is a rare, benign neoplasm of the sex cords and stroma ovary. Patients may present with abdominal pelvic pain / or distension, sometimes postmenopausal bleeding. Large tumors (> 10cm) are often associated pleural peritoneal effusion mimicking an advanced ovarian malignancy (Deimon –Meigs syndrome). We report 2 cases giant ascites pleurisy. Both patients were postmenopa...

Pleomorphic adenoma or benign mixed tumor is the most common salivary gland tumor. It is most frequently located in the parotid gland, and is considered to be a benign neoplasm accounting for 70-80% of all benign tumors of the salivary glands [1]. Benign metastasizing pleomorphic adenoma is extremely rare, with only a handful of cases described. We report a case of a histologically benign mixed...

A case is reported with clear cell sarcoma (CCS) of the hand. Early diagnosis of clear cell sarcoma is always difficult due to its slow growing nature, benign clinical appearance, lack of pigmentation in most cases, and relatively young age of patients which make it to clinically appear as a benign soft tissue tumor. We report a case of clear cell sarcoma of hand in a 56 year old male with a no...

Central ossifying fibroma is a benign, slow-growing tumor of mesenchymal origin with a predilection for the mandibular premolar and molar areas. The immunophenotype of T cells involved in the antitumor response against this benign tumor is unknown. In this case report, we described a case of a 48-year-old woman presenting with a very large recurrent ossifying fibroma in the mandible, which was ...

Adenomatoid odontogenic tumor is a non-aggressive slow growing epithelial odontogenic tumor with varied clinical and microscopic features. This neoplasm rarely appears as a completely cystic lesion histopathologically; therefore, oral pathologists should be aware of the various histopathologic types of this lesion. The main objective of this case report is to present a rare challenging case o...

leiomyoma of nasal cavity is a rare and benign tumor of smooth muscle origin that uncommonly arises from the nasal septum. we present an unusual case of histopathologically diagnosed locally extensive leiomyoma of the nasal septum which was clinically and radiologically misdiagnosed as malignancy of the nasal cavity. this case report emphasizes the rare occurrence of this entity at this site an...
