Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...
Gross image of an excised phyllodes tumor. Malignant phyllodes tumors can behave similarly to sarcomas leading to development of blood-borne metastases. [ 16 ] Approximately 10% of phyllodes tumor develop distant metastases and this occurrence is higher (20%) in patients with histological-identified malignant tumors. [ 16 ]
One weakness of adenomatoid tumor ultrasound imaging is that it is only possible if the tumor is hyperechoic. Ultrasonically can help identify if it fits this category or not. This specific characteristic in adenomatoid tumors is variable and can determine whether or not ultrasound is the right technique for the job. [11]
A juvenile active ossifying fibroma is a benign fibro-osseous neoplasm composed of mixture of ... MRI shows a variable finding depending on T1 or T2 weighted images ...
Diffuse infantile fibromatosis is a rare condition affecting infants during the first three years of life. This condition is a multicentric infiltration of muscle fibers with fibroblasts resembling those seen in aponeurotic fibromas, presenting as lesions and tumors confined usually to the muscles of the arms, neck, and shoulder area [1]: 607 Diffuse infantile fibromatosis is characterized by ...
Embryonal rhabdomyosarcoma (ERMS) is the most common histological variant, comprising about 60–70% of childhood cases. It is most common in children birth to four years old, with a maximum reported incidence of four cases per million children.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Adenomyoma is a tumor (-oma) including components derived from glands (adeno-) and muscle (-my-). [1] It is a type of complex and mixed tumor, and several variants have been described in the medical literature.
