“…Proteolytic or digestive enzymes derived from the tumor have been proposed as the cause of tumoral rupture [13,14,15,16]. Noninfective inflammation around mediastinal teratomas has been mentioned occasionally in the literature [17]. Most authorities believe that any teratoma is likely to contain intestinal, pancreatic, or salivary tissue, and this may be the cause of such cases of noninfective inflammation.…”

Germ cell tumors of the mediastinum are histologically identical to those found in the testes and ovaries. Early diagnosis and treatment improve the survival rate. Imaging studies of teratoma demonstrate a rounded, often lobulated heterogeneous mass containing soft tissue elements with fluid and fat attenuation. Calcification is present in 20-43% of cases. Seminomas are large masses of homogeneous soft tissue attenuation. Malignant nonseminomatous germ cell tumors are heterogeneous tumors with irregular borders due to invasion of adjacent structures. CT shows the location and extent of the tumors as well as intrinsic elements including soft tissue, fat, fluid, and calcification. CT is the modality of choice for the diagnostic evaluation of these tumors. MRI reveals masses of heterogeneous signal intensity, is more sensitive in depicting infiltration of the adjacent structures by fat plane obliteration, and is performed as an ancillary study.

“…Several references suggest that irritation due to increased secretion from pancreatic tissue in mature teratoma is thought to play a role in cystic formation and inflammatory reactions. 11,12) However, in our patient's histologic result, pancreatic tissue was not found.…”

A Case of Teratoma of Thyroid Gland in Adolescence

et al. 2017

Benign teratomas of the thyroid are very rare in adolescence and adults. In this review, we report a case of 14-year-old Korean girl with huge neck mass. She presented with anterior neck enlargement and compression symptom which was rapidly aggravated in 2 months. In physical examination, enlarged and firm right thyroid lobe was palpated and laboratory test of thyroid function was normal. In ultrasonography, right lobe was mainly occupied with a solid nodule size of 44×23×25 mm, showing markedly inhomogeneous hypoechogenicity. As fine needle aspiration cytology was non-diagnostic, lobectomy was done. Histological examination demonstrated that the tumor is benign thyroid teratoma composed of tissue from all three germ layers. When large thyroid nodule is detected in adolescence and malignancy could not be ruled out, final diagnosis should be made with surgical resection. And we should at least attentive for possibility of teratomas when ultrasonographic findings are suspicious.

“…On the other hand, C. K. Hayden, Jr. et al: Benign intrathoracic teratoma the tumor may have bled without rupture, in that systemic to pulmonary artery shunts have been documented after spontaneous fistula formation [2]. The fistulae, in these cases, arose after infection or from the secretion of digestive juices from intestinal tissue in the tumor [5]. No such fistula, however, was demonstrated in our case.…”

Systemic-pulmonary shunting and hemoptysis in a benign intrathoracic teratoma

et al. 1984

View full text Add to dashboard Cite

Hemoptysis as a presenting symptom in benign intrathoracic teratoma is rare, but we have documented one such case and discuss the various possibilities of why such a problem should arise. The bleeding was secondary to systemic-pulmonary artery shunting, caused at least in part by extensive pleural adhesions. The exact cause of the adhesions was not determined but possibilities include previous infection or trauma. The tumor was successfully removed surgically.
