dermoid cyst/phosphatase

Mature cystic teratomas of the ovary containing prostatic remnants are reported in 2 women aged 31 and 20 years. Both cases showed the expected histology of mature teratomas with a mixture of ecto- and endodermal structures lying in a fibrous stroma. In both cases, the foci of prostate tissue were

Four cases of mature cystic teratoma that contained prostatic tissue are reported. The ovarian tumors occurred in patients from 17 to 38 (mean 31) years of age and had no unusual clinical or gross aspects. The microscopic findings for the most part were typical of a mature cystic teratoma, but they

BACKGROUND Strumal carcinoids (SC) are ovarian tumors containing thyroid parenchyma admixed with carcinoid elements. Microscopically, the carcinoid component of SC usually presents a ribbon or trabecular pattern similar to the pattern exhibited by hindgut carcinoids. The authors designed an

A tumor suppressor gene at 10q23.3, designated PTEN, encoding a dual-specificity phosphatase with lipid and protein phosphatase activity, has been shown to play a pivotal role in the pathogenesis of a variety of human cancers. A frequent loss of heterozygosity (LOH) at 10q is found in melanoma;

OBJECTIVE Testis-sparing surgery might benefit quality of life, but can only be applied with histological examination for the presence of invasive germ cell tumour components, and the precursor carcinoma in situ (CIS). Currently, diagnosis is based on paraffin-embedded tissue, therefore a delay in

We present an extremely rare case of a benign cystic ovarian teratoma with structures of male accessory sexual glands. The patient was a 30-year-old woman. A unilocular cystic tumor, measuring 5 cm in the largest diameter, was found in her right ovary and was removed. The teratoma contained

A strumal carcinoid associated with mature cystic teratoma of the ovary in a 59-year-old was investigated immunohistochemically and electron microscopically. Histologically it was composed largely of trabecular and partly of insular carcinoid and individual thyroid follicles. Intensive argyrophilia

Gonadal germ cell tumors continue to be the cause of diverse, diagnostically challenging issues for the pathologist, and their correct resolution often has major important therapeutic and prognostic implications. They are academically interesting because of the biological diversity exhibited in the
