[Metastasis of breast cancer to a uterine leiomyoma].

The authors report a case of metastasis of cancer from the breast in a uterine leiomyoma. The metastases into the body of the uterus from extragenital cancers are rare. If they occur they are usually in the myometrium where they are asymptomatic and where the diagnosis is difficult, or in the endometrium where the diagnosis can be made by biopsy after curettage. A few rare cases of metastases in uterine leiomyoma have been reported in the literature. They can be the cause of very sudden increase in size of fibroids with compression of the pelvic organs.

[Metastatic tumors of the soft tissues of the hand. Apropos of a case. Review of the literature].

Soft tissue metastases of the hands are rare tumours, representing 0.1% of all metastases. The authors report a personal case and review the literature concerning another 21 cases. The primary tumour is generally a lung or breast cancer. These metastases appear to be more frequent in men than in women. Their rarity can be explained by the absence of routine investigation of such sites. The development of such metastases always indicates a poor prognosis.

Eosinophilia associated with a composite lymphoma.

We report a case of composite lymphoma heralded by a hyper-eosinophilia syndrome. Combination of immunophenotyping and gene rearrangement analysis allowed us to confirm malignancy and to detect a minor oligoclone B within a malignant T-cell predominant population. No evidence of retroviral infection was found using western blot and gene amplification techniques.

[The presence of an ovarian granulocytic sarcoma concurrent with a type M2 acute myeloblastic leukemia: a case].

The authors report a case of granulosa cell tumor principally located in the ovary associated with M2 type acute myeloblastic leukemia (AML) in a trisomy 22 patients. Surgery and chemotherapy were combined with a bone marrow allograft. Frequency of granulosa cell tumor is 8 percent or less of AML cases. Diagnosis is particularly difficult when haematologic expression occurs late in the disease course. An immunohistochemical work-up is required in these cases. Aetiopathogenesis is discussed. Treatment relies essentially on chemotherapy. The prognostic is variable according to different case reports in the literature.

[Placental villitis].

Placental villitis, which is defined by the presence of lymphocytic or macrophagic inflammatory cells within the villosities, constitutes a recently-described histopathological entity. This condition is the consequence of an immune response of the feto-placental unit towards a non-specific, multiple aggression and the incidence is very low. The extent of the inflammatory reaction may culminate in placentitis, resulting in miscarriage. Although a large number of infecting agents are known to be responsible for the pathogenesis of villitis, in most cases the etiology remains unknown. The hypothesis of a failure of the mechanisms of immunotolerance during pregnancy is suggested by many authors to explain their origin.

[Isolated necrotizing angiitis of the cervix uteri. Apropos of a case].

A necrotizing arteritis isolated to the uterine cervix without multisystem disease was fortuitously discovered in a 52-year old woman after hysterectomy for uterine leiomyomas. This rare lesion discovered by routine histopathological examination was cured by surgery. The aetiology and pathogenesis of this arteritis are unknown.

[Malignant transformation of an intracranial epidermoid cyst].

We report the case of a 56-year-old man who underwent removal of an intracranial epidermoid cyst 16 years ago. The cyst recurred 12 years later and was once again almost completely removed. A new recurrence 4 years later proved to be due to malignant change in the form of squamous cell carcinoma. Only 17 other cases of malignant change in an intracranial epidermoid cyst have been reported. Moreover, three other cases presented as primary intracranial squamous carcinoma.
