    Notes: Summary In a family with 4 children, 2 had slowly developing Cushing's syndrome and were adrenalectomized between the ages of 18 and 28 years. As in other cases with familial Cushing's syndrome, primary adrenocortical nodular dysplasia, the so-called adrenocortical adenomatosis, was demonstrated. The brother, now 39 years old, is in good health. The sister, however, died at the age of 36 years. Autopsy revealed a cardiac myxoma of the left atrium. A cardiac myxoma had been found incidentally at autopsy of these two patients' oldest brother, a boy who died at the age of 4 years. Both siblings with Cushing's syndrome presented additional Peutz-Jegher-like hyperpigmentation and myxomatous tumours of the skin. Identical observations of familial adrenocortical nodular dysplasia, Cushing's syndrome and cardiac myxomas have not been reported to date. However, the familial occurrence of cardiac myxomas and adrenocortical dysplasia in combination with bilateral large cell calcifying Sertoli cell tumours of the testis has been published recently.

    Notes: Summary In order to study the nature and significance of various giant cells encountered in seminomatous tumors of the testis, we reviewed the morphology of 243 consecutive pure seminomas and 107 combined (mixed) tumors, as well as the long term clinical follow-up in 26 patients. Giant cells were grouped into histocytic or neoplastic ones and the latter subtyped according to morphologic and immunocytochemical characteristics. Neoplastic giant cells were found in 34.6% of all pure seminomas and in 11.2% of all combined tumors, i.e. twice as often as histocytic giant cells in either tumor group. The various types of neoplastic giant cells were found alone or in combinations with other types. Giant cells capable of elaborating B-HCG were seen in 19.3 % of all pure seminomas and in 9.3% of seminomatous components of combined tumors. These incidences argue strongly against a trophoblastic element infiltrating a seminoma from a concomitant occult choriocarcinomatous focus. Large mononuclear giant cells, seen in spermatocytic seminomas, were observed in 15.6% of all pure seminomas, particularly in combination with B-HCG producing giant cells. Another type, characterized by marginated nuclei and eosinophilic cytoplasm were invariably part of a mononuclear cell population of similar features and encountered focally in 9.1% of all pure seminomas. Clinical follow-up, particularly in cases with B-HCG positive giant cells, revealed that treatment as for conventional seminomas at an early stage at least is followed by an excellent course.

    Notes: Summary Testicular seminomas may occur in various forms, of which the classical and spermatocytic are distinct, the anaplastic or atypical seminomas, however, less clearly defined. Lately, a separate group of particular clinical significance, comprising seminomas with syncytiotrophoblastic giant cells (STGC), has been specified. Although this type of seminoma had been recognized morphologically long ago, recent investigations have shown its ability to secrete HCG, a fact that raises serious difficulties in its differential diagnosis with combined seminomas and choriocarcinomas. Two cases of seminomas with STGC are presented and pertinent clinical and morphologic problems discussed.
