Full Answer
Mediastinal teratomas are germ cell tumors located in the anterior mediastinum, representing the most common extra-gonadal germ cell tumors. They account for approximately 15% of anterior mediastinal masses in adults and approximately 25% of anterior mediastinal masses in children.
C38.1 is a billable ICD code used to specify a diagnosis of malignant neoplasm of anterior mediastinum. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
A mediastinal dermoid cyst can be considered a variant of a mature teratoma, predominantly formed by squamous epithelium and skin appendages (ectoderm and mesoderm respectively) 9. Teratomas may either be: mature: well differentiated. immature: poorly differentiated.

Mediastinal tumors are growths that form in the area of the chest that separates the lungs. This area, called the mediastinum, is surrounded by the breastbone in front, the spine in back, and the lungs on each side. The mediastinum contains the heart, aorta, esophagus, thymus, trachea, lymph nodes and nerves.

A: Thymomas are the most common mediastinal tumors. They start in the thymus, which is a small organ in the front part of the chest under the breastbone. They represent one third of anterior mediastinal tumors and 15-20% of all tumors.
Although relatively uncommon, the precise incidence of mediastinal masses remains unclear due to lack of ubiquity in classification and definition reported in medical literature. Most tend to be benign with approximately 25% found to be malignant.

Unlike lung lesions, a mediastinal mass will not contain air bronchograms. The margins with the lung will be obtuse. Mediastinal lines (azygoesophageal recess, anterior and posterior junction lines) will be disrupted. There can be associated spinal, costal or sternal abnormalities.
Primary mediastinal B-cell lymphoma often presents with symptoms of cough, shortness of breath, or swelling of the head and neck, due to the tumor pressing on the windpipe and the large veins above the heart. With current therapies, many children with primary mediastinal B-cell lymphoma are cured of the disease.
Node resection After resection of the lung or lobe and mediastinal lymph nodes, the specimen should be examined. The lymph node stations are labeled and oriented for full pathologic review. Mediastinal lymph node dissection can be done en bloc with the lobe or lung to be removed, but this is not absolutely necessary.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
The 2022 edition of ICD-10-CM D27.9 became effective on October 1, 2021.
All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm. Morphology [Histology] Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, ...
For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned. Malignant neoplasm of ectopic tissue. Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, ...
Dermoid cyst: usually mature teratoma which resembles skin; some use these terms interchangeably. Gliomatosis peritonei: peritoneal implants exclusively composed of mature glial tissue; benign if all tissue is mature and other teratomatous elements are absent.
Definition / general. Mature if only contains adult tissues. Usually teenage women (solid) or children (cystic) Excellent prognosis, even if peritoneal implants are present. Rarely associated with hemolytic anemia.
Pathology. Mediastinal teratomas are germ cell tumors arising from ectopic pluripotent stem cells that failed to migrate from yolk endoderm to the gonad. By definition, they should contain elements from all three embryological layers: endoderm, mesoderm and ectoderm.
Mediastinal teratomas are germ cell tumors located in the anterior mediastinum, representing the most common extra-gonadal germ cell tumors.
They account for approximately 15% of anterior mediastinal masses in adults and approximately 25% of anterior mediastinal masses in children. They are by far the most common mediastinal germ cell tumor, accounting for 50-70% of such tumors 9.
In general, they have the following features: well-demarcated, displacing rather than invading adjacent structures. large: 3-25 cm 9. usually cystic: 90% 9. may be uni- or multiloculated.
Mature teratomas and most immature teratomas are benign tumors, but still, carry a risk of malignancy despite being indolent initially and require close clinical, serological, and radiological follow-up, or surgical excision 4,5,9 . There is also a low incidence of malignant transformation of somatic cells (i.e. non-germ cell components) within these tumors, e.g. carcinoma, sarcoma, leukemia 6.
Treatment depends on whether the teratoma is mature or immature. In the former, surgical resection is curative. In the later management depends on alpha-FP levels. If these are elevated then postoperative chemotherapy is usually employed 8 .
Appearances on chest radiography are usually indistinguishable from many of the other causes of an anterior mediastinal mass . Calcification may be visible.
Teratomas result from a complication in the body’s growth process, involving the way that your cells differentiate and specialize. Teratomas arise in your body’s germ cells, which are produced very early in the development of the fetus. Some of these primitive germ cells become your sperm- and egg-producing cells.
Signs and symptoms common to many teratomas include: pain. swelling and bleeding. mildly elevated levels of alpha-feroprotein (AFP), a marker for tumors. mildly elevated levels of the hormone beta-human chorionic gonadotropin (BhCG) ...
A common symptom is a swelling at the tailbone, which obstetricians look for in newborns. Your doctor may use X-ray of the pelvis, ultrasound, and CT scans to help diagnose a teratoma.
Sometimes ovarian teratoma can be accompanied by a rare condition known as NMDA encephalitis. This can produce intense headaches and psychiatric symptoms including confusion and psychosis.
In about 1 in 500,000 people, a very rare type of teratoma can appear, called fetus in fetu (fetus within a fetus).
Sacrococcygeal (tailbone) teratoma. A sacrococcygeal teratoma (SCT) is one that develops in the coccyx or tailbone. It’s the most common tumor found in newborns and children, but it’s still rare overall. It occurs in about 1 in every 35,000 to 40,000 infants.
Immature (malignant) ovarian teratomas are rare. They’re usually found in girls and young women up to the age of 20.

The mediastinum is the cavity that separates the lungs from the rest of the chest. It contains the heart, esophagus, trachea, thymus, and aorta. The mediastinum has three main parts: the anterior mediastinum (front), the middle mediastinum, and the posterior mediastinum (back). Specialty: Oncology. MeSH Codes:

Pure mature and immature teratomas derived from no transformed ovarian germ cells. Teratomatous components of mixed germ cell tumors derived from their associated nonteratomatous components.
Extensive sampling may be needed to include areas of immature teratoma at the time of frozen section in cases where a preoperative diagnosis of immature teratoma is suspected; sample nodular, soft appearing and mass forming areas
Malignant germ cell tumor of the ovary composed of cells from the three germ layers, containing variable amounts of mature and immature tissue. Affects mostly young females < 20 years old. Grossly solid ovarian tumor mass with necrosis and hemorrhage on cut sections. Grading is performed based on the amount of immature neuroepithelium.
