background: inflammatory myofibroblastic tumor (imt) is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. the most common sites of involvement include the lung, liver and orbit, but it has been reported to occur in nearly every site of the body, including oral cavity and soft tissue. although common in other sites, such a tumo...

breast sarcomas have relatively been rare and accounted for 1% of all primary malignant tumors of the breast. pure and primary chondrosarcoma of the male breast would be an extremely rare tumor. it might arise either from the breast stroma itself, or from underlying bone or cartilage. a 65-year-old man has presented with a rapidly growing breast mass since 5 months. physical examination has est...

splenogonadal fusion is a rare congenital malformation whereby the splenic tissue is found attached or surrounded by the testis, and presents in both continuous and discontinuous forms. splenogonadal fusion may be misinterpreted as a primary malignant testicular or an adenomatoid tumor. knowledge about the existence of such an entity is essential in order to preserve the testis during surgical ...

Malignant phylloides tumor is a relatively rare and rapidly growing tumor of the breast. Presentation during pregnancy is uncommon. Reports regarding malignancy in these tumors differ greatly in incidence, and most of them are stromal malignancies. We report this case in which 24-year old primigravid patient in the 36th week of her pregnancy had a malignant phylloides tumor of breast with sudde...

adenoid cystic carcinoma is an uncommon, slow growing malignant salivary gland tumor that is characterized by wide local infiltration, perineural spread, propensity to local recurrence anddistant metastasis. in this paper, the authors present a case of adenoid cystic carcinoma affecting the palate and involving the maxillary sinus in a 60‑year‑old male patient along with a brief reviewof litera...

Primary peritoneal tumors share a common anatomical site and therefore their clinical manifestations are very similar. When masses detected, the tentative initial diagnosis is secondary to metastatic disease, which has been determined most frequently in cavity. However, primary should always be included differential diagnosis. Among malignant neoplasms, mesothelial have identified (malignant me...
