[An endodermal sinus tumor (yolk sac tumor) of the anterior mediastinum].

An own case of a primary mediastinal endodermal sinus tumour (yolk sac tumour) is presented that was transformed under therapy into an AFP-negative process and occurred combined with an arcus aortae dexter. This is followed by a description of the clinical and diagnostic patterns of signs and symptoms and of the treatment of this very rare dysontogenetic tumour.

Endodermal sinus tumor and embryonal carcinoma of the ovary in a 53-year-old woman.

BACKGROUND: Germ cell tumors, the most common ovarian malignancies in females under the age of 21, are rare in older women. We report an unusual case of a mixed embryonal carcinoma and endodermal sinus germ cell tumor in a perimenopausal patient and review the differential diagnosis and management of these malignancies with respect to age. CASE: A 53-year-old woman complaining of irregular menses and pelvic pain was found to have a large pelvic mass and a positive pregnancy test. Subsequent investigation revealed a large left adnexal mass, and an elevated beta-HCG and alpha-AFP. At laparotomy, a mixed germ cell tumor was found. The patient was treated with multiagent chemotherapy and currently is without evidence of disease. CONCLUSION: Although rare, the diagnosis of germ cell tumor should be considered in older women presenting with a large pelvic mass. The treatment and prognosis is similar regardless of age, except that reproductive-sparing surgery is not a priority in the older patient.

[Endodermal sinus tumor. Histological changes induced by chemotherapy].

The case of a child affected at birth sacrococcygeal teratoma is reported. Twenty-eight months following surgical resection, the tumor relapsed locally and liver metastases occurred. A biopsy of the sacrococcygeal mass was performed and histologic examination proved it to be an endodermal sinus (yolk sac) tumor. Chemotherapy consisting of etoposide and high-dose carboplatin was started. When a second operation was performed the mass had disappeared and the macroscopically involved areas of liver were removed. Histologic examination demonstrated that the complete necrosis of the tumor was partially replaced by a fibrous scar tissue. The child underwent adjuvant chemotherapy and now is in complete remission fourteen months after the last operation.

[An extragonadal retroperitoneal endodermal sinus tumor--results of treatment and treatment sequelae in a 3-year-old boy].

A case of an extragonadal endodermal sinus tumour in a three-year old boy is presented. Complete resection of the retroperitoneal tumour was possible after initial chemotherapy. Combined radio-chemotherapy after tumour removal led to complete remission now lasting for more than 5 years. There was unilateral renal atrophy and diverticulum of the stomach as treatment related complications. The favourable prognosis of this tumour due to intensified treatment is discussed in relation to treatment sequelae. The interdisciplinary approach in treatment of cancer in children is emphasized.

Bleomycin-induced hyperpigmentation and hypersensitivity reactions to etoposide and vinblastine in a child with endodermal sinus tumor.

We report a pediatric case who developed bleomycin-induced hyperpigmentation and hypersensitivity reactions to both etoposide and vinblastine while receiving chemotherapy for germ cell tumor. Skin hyperpigmentation related to chemotherapeutic agents has been reported only rarely in pediatric patients. This patient developed a characteristic skin hyperpigmentation which was "flagellate" in appearance. Two features of the hyperpigmentation were noteworthy: development at a low cumulative dose of bleomycin and persistence after cessation of chemotherapy. Additive effect of cisplatinum-induced hyperpigmentation was suggested. Although hypersensitivity reactions to etoposide have been previously reported, hypersensitivity reactions to vinblastine are almost unknown. To our knowledge, this is the first report of hypersensitivity reaction to vinblastine in a child in English literature.
