[Unilateral anorchidism or monorchidism].

Monorchidism is a Testicular Regression Syndrome (Vanishing Testis Syndrome), defined as the unilateral or bilateral partial and complete absence of testicular tissue with or without rudimentary epididymal and spermatic cord remnants in the presence of normal duct development and normal external genitalia. In this paper we report the results of a personal series of 36 patients. We discuss the histopathology and try to answer the question whether protection of the solitary contralateral testis by orchidopexy is necessary in monorchidism. Our results suggest that a fixation of the contralateral testis is not necessary in children operated on for monorchidism. The histopathological findings provide a support for the concept of in utero torsion of the testis as the basis for the Testicular Regression Syndrome. These findings are characteristic, if non-specific. Vas deferens, epididymis, calcification or hemosiderin pigmentation was noted in almost 90% of the cases. In the absence of these remnants clinical and surgical findings and the presence of a richly vascular stroma supported the diagnosis.

[Stress ulcer by hypovolemic shock in pregnant and normal rabbits and in the fetuses (author's transl)].

The purpose of this experimental work was to study the possibility of stress ulcer in fetal Surgery. Firstly an experimental model of production of stress ulcer by hypovolemic shock was worked out: by removing a volume of blood equivalent to 2% of body weight out of the femoral artery, a stress ulcer was was regularly induced in 25 female rabbits in the fundic area within 3 hours. In 10 pregnant rabbits and in the fetuses a stress ulcer could not be produced by the same method. This observation suggests the hypothesis that the reactions of the gastric wall are modified by the specific hormonal situation of the pregnant rabbit. This assumption ought to be elucidated by further investigations.

[The blue rubber bleb nevus or the cellular blue nevus or Bean syndrome. A rare case of iron-deficiency anemia].

Described by Bean in 1958 the Blue rubber bleb nevus syndrome is a viscero-cutaneous hemangiomatosis, a rare condition associating typical cutaneous and visceral hemangiomas of the cavernous type. We report the case of a four year old boy who presented a microcytic and hyperchromic anemia. The previous medical history of this boy was characterized by a large cavernous angioma on the right hand operated on the at the age of three months. The stools were guaiac-positive; examination of the gastrointestinal tract to clarify the etiology of gastrointestinal bleeding was negative. An oral iron therapy was prescribed for several years by the pediatrician. At age nine and half years Labeled erythrocytes demonstrated that gastrointestinal bleeding still continues. The indication for surgical operation was established: Small bowel enteroclysis revealed an oval filling defect in the lumen of ileum. Intraoperative finding: Protuberous hemangioma in the wall of small bowel; resection of the involved intestine and primary anastomosis were performed. On histological examination a cavernous hemangioma has been observed. Clinic and Pathology of this rare condition are discussed.
