[Thyroid microcarcinoma with a fatal outcome and 34 other unusually aggressive cases reported in the literature].

A follicular thyroid microcarcinoma was revealed by scapular metastases. Despite treatment, other metastases were the cause of death after a course of 14 years. In the medical literature there are at least thirty-four other examples of follicular or papillary carcinoma of less than 15 mm (previously called occult) that have either given rise to blood-born metastases or have been the cause of death. Present data from light and electron microscopy, immunohistochemistry and microspectrophotometry cannot differentiate between small and large carcinomas. Microcarcinomas (particularly papillary ones) are frequent in the general population and are found in 5% of thyroids. They are usually not aggressive. Those which show vascular or capsular invasion, a lack of lymphoid infiltrate and large cervical lymph node metastases are more likely to have an unfavorable course. The discovery of a microcarcinoma in a thyroid cells for an extended follow-up.

[Neonatal carcinoma. Review of the literature apropos of a case].

A cortical adrenal carcinoma arising during the neonatal period and associated with virilization recurred after an initial excision and is in complete remission after a follow-up period of 10 years. The authors have performed a review of the medical literature which has yielded 56 neonatal carcinomas including this one. More than half of these cases concerned the thyroid gland (15 cases) and the adrenal cortex (14 cases). These were followed by malignant melanomas (12 cases), carcinomas of the parotid gland (6 cases), oropharyngeal region (3 cases), adrenal medulla (2 cases) and stomach, liver, breast and cutaneous sweat gland (one case each). Six tumors were associated with congenital malformations which included Beckwith-Wiedeman's syndrome; 4 tumors arose from preexisting tissue lesions; in one case, oral contraceptives were taken during pregnancy. The main treatment of neonatal carcinomas is surgery. Local recurrences (7 cases) do not markedly affect the outcome, whereas metastases (12 cases) have a very unfavorable prognosis. Superficial tumors are diagnosed earlier and more frequently cured. Out of 44 cases for which the outcome is known, only 18 children survived.

Angioinvasive plasma cell granulomas of the lung.

A series of eight plasma cell granulomas of the lung were examined. Their clinical, pathologic, and immunohistochemical characteristics as well as the ultrastructural features of one case are in agreement with those found in the literature. One patient died after a surgical intervention complicated by invasion of pulmonary veins. This led to a search for vascular injuries in the other cases. On the whole, of eight cases, two showed vascular invasions at a distance, five (including the preceding ones) showed invasion of medium-sized blood vessels in the peripheral parts of the lesion, and three showed older invasions in their center; only two had no vascular lesions. To the authors' knowledge, vascular invasion at a distance has been reported only once to date. An inflammatory origin for these cytologically benign lesions remains possible, although a striking resemblance with intravascular fasciitis can also be shown. These lesions should be treated by radical and precocious surgery.

[Sacrococcygeal teratoma in 2 fetuses at 5 and 6 months].

The two large mature sacro-coccygeal teratomas reported seem to be responsible for the death of fetuses in the fifth and sixth months of pregnancy. A review of the literature shows that teratomas are exceptionally rare during this period. Their outcome depends upon the degree of maturity of the tumor, its size, whether its location is pelvic or not, the presence of any associated malformations and upon prematurity.

[Giant cell lesions of the mandible: problems of differential diagnosis apropos of 3 cases of central giant cell reparative granuloma].

Three cases of central giant cell reparative granulomas of the mandible are reported. The first shows classic manifestations. The second illustrates the role of traumatism in the genesis of these lesions. The third highlights the effect of pregnancy in their growth. The bilateral character of the lesions in this last patient led us to evoke the diagnosis of hyperparathyroidism and cherubism. They were ultimately discarded. A diagnostic approach is proposed which takes into account the location of the lesion and the medical history of the patient. Both experimental data concerning the potential of the cells found in the ramus of the mandible in laboratory animals and notions which apply to the periodontal bone remodelling enable one to better understand and differentiate between the central giant cell reparative granuloma and the genuine cell tumor of the mandible.
