Malignant melanoma of the conjunctiva – successful surgical excision of the primary tumor and reconstruction by conjunctival auto transplantation from the contralateral eye.

Malignant melanoma of the conjunctiva is a rare tumor with incidence of 0.5 cases/year per million population. It may also occur as de novo, as on the basis of preexisting melanocytic lesions (nevus or freckle) or most often from the so-called primary acquired melanosis of the conjuctiva (PAM).

[Two autopsy cases with microchimerism].

Identification of chorionic villi in spiral arterioles and later in maternal circulation is known as maternal microchimerism. Distant consequences of this condition are unclear associated mainly with risk from autoimmune diseases. Our presentation is aiming at introducing the term microchimerism and to propose a connection between this phenomenon and the reasons for the death of the fetus.

[Intrauterine fetal death in furcate insertion of umbilical cord].

Fatal complications associated with abnormal umbilical cord insertions occupy 7.7-11.4% of all stillbirths and only 0.

[Single umbilical artery (SUA)].

Single umbilical artery (SUA) is the most common abnormality of the umbilical cord. It is associated with an increased incidence of atresia of hollow organs, renal abnormalities, limb reduction defects and spontaneous abortions. The aim of our study is to establish the association of SUA with types of malformations and the corresponding pathology of pregnancy and parturition.
