Adult T-Cell Leukemia/Lymphoma in a Caucasian Patient After Sexual Transmission of Human T-Cell Lymphotropic Virus Type 1.

Adult T-cell leukemia/lymphoma (ATLL), a T-cell neoplasm caused by human T-cell lymphotropic virus type 1 (HTLV-1), develops in the majority of cases in individuals who were infected with HTLV-1 as young children, by their mother during prolonged breastfeeding. We report the case of a Caucasian French man, whose parents were HTLV-1-seronegative and who developed ATLL after HTLV-1 sexual transmission by a Cameroonian woman. This hypothesis was corroborated by genotyping of the patient's virus, which revealed an HTLV-1B strain, found only in Central Africa, especially in Cameroon.

Specific infiltration pattern of FOXP3+ regulatory T cells in chronic histiocytic intervillositis of unknown etiology.

Introduction: Chronic histiocytic intervillositis of unknown etiology (CIUE) is a rare placental lesion characterized by an intervillous mononuclear inflammatory infiltrate of maternal origin. Although the mechanism and origin of these lesions are currently not understood, they appear to be related to an immune conflict between mother and fetus cells.

Aim: To clarify the inflammatory cell profile and evaluate the T regulatory lymphocyte (Treg) status in CIUE.

[Degeneration of dermoid cysts: a case study of malignant transformation].

Malignant transformation of ovarian dermoid cyst (mature cystic teratoma) is rare and most often established in postmenopausal women after surgery by sample anatomopathological analysis. We report the case of a 58-year-old woman showing abdominal pain associated with constipation episodes. The diagnosis of dermoid cyst was established upon ultrasonographic and tomodensitometric criteria.

Mesoblastic nephroma: prenatal ultrasonographic and MRI features.

Antenatal detection of mesoblastic nephroma by US is possible. Reviewing the literature, we found 19 previously reported cases, only 1 of which underwent prenatal MRI. We present a further case diagnosed by US and confirmed with MRI.

[Autoimmune hemolytic anemia associated with a mature ovarian teratoma].

Unlabelled: The association of autoimmune hemolytic anemia and mature teratoma of the ovary is rare, particularly in childhood, but must be known and looked for since the treatment of teratoma allows to cure anemia as well.

Case Report: A 9 year-old girl was admitted for hemolytic anemia. The etiologic work-up revealed an autoimmune mechanism (IgG autoantibodies with complement), as well as an ovarian tumor after ultrasound sonography of the abdomen and pelvis.

[Polymorphic sweat gland adenocarcinoma of low grade of malignancy].

Recently, Suster and Wong added a distinctive entity to the large nomenclature of sweat gland carcinomas. This tumor is equivalent to the polymorphous low-grade adenocarcinoma of minor salivary glands. It is characterized by its variegated architecture and its relatively indolent behaviour.
