Schwannomas are soft tissue sarcomas arising from neurilemma of Schwann cells in peripheral nerves, and is the most frequent type of benign tumor found in these nerves. We report a case of a Schwannoma of the ulnar nerve in the elbow joint, and along this report, give a review of the literature. A 46-year-old male patient was hospitalized with complaints of swelling and pain in the left elbow and a tingling sensation and hypoesthesia of the fourth and fifth fingers. Physical examination of the patient showed he was positive for Tinel's sign, and magnetic resonance imaging results demonstrated the presence of a Schwannoma. Subsequent biopsy and excision of the Schwannoma was carried out. The suspected mass, which had a clear margin separating it from the healthy nerve of the medial left elbow, was removed along with its 2 x 2 x 3 cm capsule after a histological diagnosis of a Schwannoma was made. Pathophysiological results confirmed the excised mass as a Schwannoma. Schwannoma of the ulnar nerve within the elbow joint is rare and differential diagnosis is difficult. Therefore, treatment can only proceed after the presence of Schwannoma has been confirmed by physical and radiological examinations.

Testicular feminization is an uncommon genetic disorder with considerably familial predisposition and results in total feminization due to end-organ unresponsiveness to androgens. It is characterized by the presence of testes in phenotypically female with adequate breast development, normal extemal genitalia, absence of mullerian structures, and meager or absence of body hair. These patients characteristically have male karyotype(XY) and negative sex chromatin and are at increased risk of undergoing malignant transformation of the undescended gonad. In recent times, the malignant potential of the dysgenetic gonads in the intersex patients with a Y chromosome has been stressed by many authors, but few reports of an association between testicular feminization syndrome and benign tumors such as Sertoli cell adenomas. In the present study, postoperative pathology revealed that the gonads were Sertoli cell adenomas. The main features of clinical presentation and histological studies are briefly discussed with a review of the literature.

Spontaneous rupture of the bile duct is an exceedingly rare and usually recognized fatal cause of peritonitis and intraabdominal sepsis. Several reports of isolated cases have demonstrated its rarity in the absence of operative trauma or severe injury. Perforation of the biliary system occurs most frequently in the gall bladder, which perforation of the hepatic duct is less common, being described mainly in infants, but extremely rarely in adults. The diagnosis of the spontaneous rupture of the bile duct depends on meticulous clinical examination and imaging investigation. The basic principles of treatment are to stop the bile leakage, evacuate the extravasated bile, apply decortication of the encapsulated fluid collection and provide adequate drainage. We report on a patient with spontaneous perforation of the right hepatic duct who presented with abdominal pain, jaundice and fever. Exploratory surgery showed proximal common bile duct obstruction with right hepatic duct perforation.

Lymphangiomas are rare congenital benign tumors arising from the lymphatic system, and are mostly encountered in the neck and axillary regions of pediatric patients (95%). Lymphangioma of the pancreas is extremely rare accounting for less than 1% of these tumors. We report here on a case of pancreatic cystic lymphangioma. A 54-year-old woman presented with intermittent postprandial abdominal discomfort and radiating back pain. Abdominal computed tomography scan revealed 8 x 6.5 cm hypodense cystic mass arising from the tail of the pancreas without septa or solid component. The initial impression was a pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenectomy. The histopathologic and immunohistochemical study helped make the diagnosis of a pancreatic cystic lymphangioma. Herein, we report a case of pancreatic cystic lymphangioma mimicking pancreatic pseudocyst and review the relevant medical literature.

PURPOSE: The purpose of the study was to evaluate the relationship between the location of bone signalabnormality and associated injury, as seen on MR, in patients with acute knee joint injury. MATERIALS AND METHODS: Thirty-six patients with acute knee injury and bone signal abnormalities on MR were included in this study. Thefemur and tibia were each divided into six compartments, namely the anteromedial, medial, posteromedial,anterolateral, lateral, and posterolateral ; these were obtained in each knee joint. We evaluated the location ofbone signal abnormality and the corresponding arthroscopic or operative findings of injury to ligaments andmenisci. Cases with signal abnormalities involving more than three compartments were excluded. RESULT: Bonesignal abnormalities were demonstrated in 51 compartments. Most(84%, 43/51) were noted in the lateral half of theknee joint, the most common location being the tibio- posterolateral compartment(13/51). The femoro-lateral(11/51) and tibio- anterolateral compartment(8/51) were the next most common locations. All cases(13/13)with bone signal abnormality in the tibio- posterolateral compartment had tears at the anterior cruciate ligament,while 9 of 11 cases(81%) with abnormality in the femoro- lateral compartment had tears at the anterior cruciateligament. Six of eight cases(75%) with signal abnormality in the tibio- anterolateral compartment had tears at theposterior cruciate ligament ; 31 of 43 cases (72%) with abnormality in the lateral half of the knee joint hadtears at the medial collateral ligament. Six of eight cases(75%) with signal abnormality in the medial half of theknee joint had tears at the medial meniscus, but no lateral meniscal tear was found. Among patients with signalabnormality in the lateral half of the knee joint, the tear was lateral meniscal in nine of 43 cases(21%) andmedial meniscal in six of 43(14%). CONCLUSION: The location of bone signal abnormality, as seen on knee MR, inpatients with acute knee joint injury could be an important finding suggesting associated injury.

Primary angiosarcoma of the spleen is an extremely rare malignancy, the pathogenesis of which is not completely understood, with high metastatic potential and an exceedingly poor prognosis, regardless of treatment regimen. The major complication is splenic rupture, which often leads to fatal hemoperitoneum. Overall, since 1879 when Langerhans described the first case of angiosarcoma of the spleen, there have been approximately 200 cases reported in the literature. Moreover, to the best of our knowledge, spontaneous rupture of primary splenic angiosarcoma and spontaneous rupture of remnant or recurred angiosarcoma is extremely rare, and no cases were reported in English literature. We report a case of spontaneous splenic rupture due to angiosarcoma in a 68-year-old man, and also review the existing literature.

Myxoid liposarcoma of the spermatic cord (MLSC) is a rare variant of spermatic sarcoma. Typically, it presents during the sixth decade of life as a painless scrotal or inguinal mass. Although local recurrences are not uncommon, prognosis following complete tumor removal is good because metastases are rare. Although myxoid liposarcoma is common elsewhere in the body, less than 20 cases have been described in the spermatic cord. Distant metastasis with MLSC (e.g., bone, liver, lung) is extremely rare, and no cases have been reported in the English literature. We report one case of MLSC with multiple bone, liver and peritoneal metastasis, incidentally found during inguinal hernia repair.
