These pelvic tumors have a greater likelihood of being malignant. An early survey found that the rate of tumor malignancy was 48% for girls and 67% for boys older than 2 months at the time of sacrococcygeal tumor diagnosis, compared with a malignant tumor incidence of 7% for girls and 10% for boys younger than 2 months at the time of diagnosis.
Currently, the medical field prefers to use the term lymphatic malformation, because the term cystic hygroma means water tumor. [3] Lymphatic malformation is more commonly used now because it is a sponge-like collection of abnormal growth that contains clear lymphatic fluid. The fluid collects within the cysts or channels, usually in the soft ...
The diagnosis of pancreatic MCN is typically achieved with imaging. If the results of imaging (CT/MRI) are unclear, then endoscopic ultrasound with fine needle aspiration (EUS-FNA) of the cyst may be necessary. [1] Cyst fluid analysis may help distinguish potentially premalignant mucinous cysts (MCNs and IPMNs), from benign non-mucinous cysts. [1]
A teratoma may contain elements of other germ cell tumors, in which case it is not a pure teratoma, but rather is a mixed germ cell tumor and is malignant. In infants and young children, these elements usually are endodermal sinus tumor, followed by choriocarcinoma. Finally, a teratoma can be pure and not malignant yet highly aggressive; this ...
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta- human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
Macrocystic have cysts greater than 2 cubic centimetres (0.12 cu in), and microcystic lymphatic malformation have cysts that are smaller than 2 cubic centimetres (0.12 cu in). [2] These malformations can occur at any age and may involve any part of the body, but 90% occur in children less than 2 years of age and involve the head and neck.
Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.
It is the most common testicular tumor in children under three, [2] and is also known as infantile embryonal carcinoma. This age group has a very good prognosis. In contrast to the pure form typical of infants, adult endodermal sinus tumors are often found in combination with other kinds of germ cell tumor, particularly teratoma and embryonal ...
