RESUMO
The shape and the position of the stomach and its anatomic relations to the round viscera vary from individual to individual, but they also vary in the same subject depending on many factors. The downward displacement of the stomach is called gastroptosis. In the literature, there are only five case reports where the stomach constituted the content of a femoral hernia. The current study presents a case of a gastric femoral hernia in a cadaver along with a review of the relevant literature. During routine dissection of a 67-year-old male cadaver with a very large stomach and gastroptosis, a femoral hernia containing a part of the great curvature of the stomach was found. The length of the hernia sac was 5 cm, and its width was 3.5 cm. There was a disposition of the intestinal coils to the posterior wall and the lesser pelvis. The cadaver's former medical history and skin observation before dissection excluded any previous abdominal surgery. This is the second case of stomach herniation through the femoral ring in a male subject ever reported. The symptoms in this pathology vary from complete absence to symptoms due to high stenosis of the digestive tract, stomach strangulation and stomach wall necrosis.

The superficial ulnar artery (SUA) is an ulnar artery of high origin that lies superficially in the forearm. Its reported frequency ranges from 0.17% to 2%. During anatomical dissection in our department we observed a unilateral case of SUA in a 75-year-old white male human cadaver. It originated from the right axillary artery at the level of the junction of the two median nerve roots and followed a looping course, crossing over the lateral root of the median nerve and running lateral to it in the upper and middle thirds of the arm, whereas in the inferior third of the arm the SUA crossed over the median nerve and ran medially to it. In the cubital fossa, it passed superficially over the medial side of the ulnar aponeurosis and coursed subcutaneously in the ulnar side of the forearm superficially to the forearm flexor muscles. In the hand the SUA anastomosed with the superficial palmar branch of the radial artery, creating the superficial palmar arch. Additionally, it participated in the development of the deep palmar arch. The axillary artery, after the origin of the SUA, continued as the brachial artery and divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. No muscular or other arterial variations were observed in this cadaver. The embryological interpretation of this variation is difficult and it may arise as a result of modifications to the normal pattern of capillary vessel maintenance and regression. The existence of a SUA is undoubtedly of interest to the clinician as well as to the anatomist. This report presents a case of unilateral SUA along with a review of the literature, embryological explanation and analysis of its clinical significance.

Femoral hernia, which is a less common occurrence than inguinal hernia, is not congenital in most cases and is uncommon in young males. It is considered to be more common in females than in males due to an enlarged femoral ring in the former. A case of bilateral femoral hernia in a 64-year-old male cadaver is described within the framework of an anatomical approach. On the right side, the protrusion of the viscus appeared as a small intestine coil, whereas on the left side the protruded viscus appeared as a pelvic colon's appendix appiplocae. On both sides, the protruded viscus was located in front of an aberrant obturator artery, which oriented from the external iliac artery and not from the internal iliac artery as should be the case. The puberal branch of the inferior epigastric artery was absent. The cadaver's medical history and his skin examination excluded an abdominal surgery. In the literature, case reports of bilateral femoral hernia appear only seldom, especially those of male patients who had not undergone inguinal hernia repair surgery. In femoral hernias more often than in other types of hernia, the protruded viscus is strangulated and undergoes a tissue necrosis. Morbidity and mortality for complicated femoral hernia is high. Knowledge of vascular variation such as presented by the cadaver under study is extremely useful to the surgeon because any iatrogenic injury of the aberrant obturator artery during a laparoscopic repair may result in dangerous hemorrhage.

PURPOSE: Even though acute lymphoblastic leukemia (ALL) responds well to chemotherapy, relapse remains the major problem. This study documents relapse and survival rates in 85 consecutive children (33 at good risk, 52 at high risk) with ALL diagnosed in 1991 to 1996. PATIENTS AND METHODS: Until 1993, the New York II protocol for the high-risk group and a combination of UKALL XI (induction) and R blocks of ALL-REZ BFM-87 (intensification) regimens for patients at good risk were used. To reduce toxicity, the protocols were subsequently modified. Consolidation treatment was the same for both groups, consisting of a lower cytarabine dose and methotrexate removal, whereas intensification was changed only for the high-risk group using the BB block of the NHL-BFM-90 protocol. The bone marrow clearance of leukemia was assessed on day 22, and minimal residual disease was detected using polymerase chain reaction analysis of Ig heavy-chain gene rearrangements. RESULTS: Seventy patients had common precursor B lineage ALL, six had pre-B-ALL, eight had T-ALL, and one had B-ALL. Two patients never achieved remission and died. Six patients died of consolidation-related complications. Four more patients died, two during induction and two during maintenance therapy. Two other children had relapse (2.3%), both of whom were treated with the earlier protocols and then underwent bone marrow transplantation. Four more children with morphologically complete remission showed minimal residual disease (which reached the levels of 1 leukemic cell among 10(2)-10(4) normal cells) with the use of clone-specific probes at several points of the study intervals, but never had relapse. The 5-year overall and event-free survival rates were 86% and 83%, respectively. The 5-year overall survival rates for good-risk and high-risk groups were 94% and 81%; the corresponding event-free rates were 91% and 78%. The 5-year event-free survival rate in the patients at high risk was significantly higher after the protocol change (90% vs. 65%, P = 0.04). CONCLUSIONS: The modification proved to be effective in diminishing the therapeutic toxicity and improving the efficacy, mainly for the high-risk group.

Non-Hodgkin's lymphomas (NHL) were often erroneously diagnosed as other malignancies and treated accordingly. In this study cisplatin combined with vincristine, cyclophosphamide, and Adriamycin was used incidentally as a front-line treatment in seven children with NHL, because the initial histologic diagnosis was that of a sarcoma. After reevaluation three patients had Ki-1 anaplastic large cell lymphoma of T-cell origin, two abdominal B-cell diffuse high-grade NHL, one mediastinal diffuse large B-cell lymphoma, and one B-cell lymphoma in the stomach. They received at least two courses of cisplatin combined regimen and continued with other protocols for NHL. All patients showed an extremely good response from the first course of therapy and the masses vanished completely. They were followed up for a mean time of 29.5 months and are all in complete remission. The data indicate that cisplatin is active against NHL and might be a promising alternative front-line therapy.

Anaplastic large cell lymphoma is a rare malignancy in childhood. We describe the case of a 6-year-old boy with Ki-1 lymphoma of the thymus who presented with an endocardiac mass. The first histologic analysis suggested a high-grade undifferentiated sarcoma, but reevaluation and immunohistochemistry confirmed the CD30+ lymphoid derivation of the process. The patient was given chemotherapy and 24 months later he remains in complete remission. It is noted that echocardiography was repeated many times to detect heart lesion.
