Benign ulceration of the cecum is an uncommon lesion that was originally described by Cruveilhier in 1832. Etiology is unknown and symptomatology not pathognomonic. Pre-operative and intraoperative diagnosis is rare and difficult. Definitive diagnosis is usually obtained by histologic evaluation of the surgical specimen after a right hemicolectomy performed for a suspect of a neoplasm of the cecum. The authors present 7 cases of cecal ulcers and suggest that preoperative diagnosis may be due after a colonoscopy with biopsy. This examination may be performed only in that cases that appear without symptoms of acute abdomen. The authors suggest also to perform right hemicolectomy.

The experience of operative treatment in 14 cases of acute abdomen complicated by malignant hemopathy was reported. Primary diseases consisted of AL, NHL, MM, MH and MDS-RA, 13 cases of them were at progressing stage. The acute abdominal conditions included acute appendicitis, acute pancreatitis, acute cholecystitis, peritonitis secondary to intestinal perforation, intestinal obstruction, primary peritonitis and ileocecal syndrome. The type of acute abdomen was related with primary desease and chemotherapy. 8 cases were operated and 2 of them died of complications after operation. Biopsy of excised tissue showed tumor cells in 2 cases. The rate of correllation between preoper active and postoperative diagnosis was 62.5%. These findings suggest that malignant infiltration in the viscera, duration of abdominal pain before operation and the change of blood picture are the major factors for determining operative indication and the postoperative prognosis.

A 3-year-old boy presented with persistent abdominal pain, hematuria and facial pallor with progressive anemia. A computed tomography scan showed a massive intraperitoneal hemorrhage and tumor mass in the bladder. Histological examinations of the resected tumor revealed findings of pseudosarcomatous myofibroblastic tumor (PMT). The clinico-pathological features of this case warn us that PMT can cause acute abdomen syndrome with massive intraperitoneal hemorrhage.

The experience of diagnosis and treatment of the ovarial tumor and cyst in 68 girls was summarized. Children were admitted to the hospital with an acute abdomen signs and in a planned order as well. All the patients were operated on. Children with benign ovarial tumor and cyst are alive. Four patients with malignancy have died.

Lymphangioma is an uncommon tumor. Lymphangiomatosis, a benign tumor consisting of a cluster of dilated lymphatic channels, is very unusual. Most lymphangiomatoses are found in the neck and head area. Less than 5% are diagnosed intraabdominally and they are very infrequently encountered in the retroperitoneal area. Herein, we report a rare case of a 32 year-old woman who had disseminated intra-abdominal and retroperitoneal cystic lymphangiomatosis, which presented as acute abdomen. She received exploratory laparotomy due to the suspicion of malignancy, which was finally confirmed as cystic lymphangiomatosis. The clinical manifestations, imaging features, and management of this patient are discussed and compared with previous literature.

The case of an ovarian cavernous hemangioma with torsion in an 8-year-old girl is described. Current literature records less than 50 cases of which only 8 are in children. The presenting symptoms of acute abdomen and the ultrasonographic study led to the preoperative diagnosis of torsion of an ovarian tumor. Salpingo-oophorectomy and appendicectomy were performed with an uneventful postoperative course. The histological pattern of the tumor was that of an entirely cavernous hemangioma. The case is reported in view of its rarity.

Ovarian carcinoma commonly occurs in postmenopausal women and often presents with an insidious course. Acute abdomen is rarely an initial symptom. When these patients present with abdominal discomfort, the disease has already spread throughout the peritoneal cavity. We present a case of mucinous cystadenocarcinoma in a young woman who presented with acute abdomen and intra-abdominal bleeding. This 24-year-old woman was previously diagnosed with a ruptured left ovarian cystic tumor at a primary clinic. She underwent emergency exploratory laparotomy, followed by unilateral salpingo-oophorectomy at the clinic. No thorough examination of the peritoneal cavity was done during surgery. The diagnosis of mucinous cystadenocarcinoma was accidentally over-looked until one month later when she returned for routine follow-up. Upon referral to our clinic, the patient underwent a repeat laparotomy. The surgicopathologic diagnosis was intraperitoneal carcinomatosis stage IIIC that could not be excised completely, even though rigorous staging surgery including washing cytology, total abdominal hysterectomy, salpingo-oophorectomy, retroperitoneal lymphadenectomy, appendectomy, infracolic omentectomy and excision of any suspicious and removable lesions were performed. This case alerts us to consider the possibility of ovarian malignancy when a young woman presents with an acute abdomen secondary to ruptured ovarian cystic tumor and intraperitoneal hemorrhage. Careful preoperative preparation and thorough intrasurgical examination of the peritoneal cavity along with a prompt pathologic diagnosis of suspicious lesions will prevent missed diagnoses.

The spontaneous hematoma of rectus abdominis sheath is a rare condition which usually presents as acute abdomen. We report our experience with 19 patients, most of them on treatment with oral anticoagulants. The most common symptoms were abdominal pain and palpable tumor. Twenty-six percent required blood transfusion. Echography and computerized tomography, were useful for diagnosis. Treatment was mainly conservative and was the mode of choice; surgery was left only for those patients who had hemodynamic changes or infection of the hematoma.

We report elevated serum carcinoembryonic antigen (CEA) in a case of malignant carcinoid tumor of the appendix with liver and lung metastasis. A 55-year-old Thai man was found to have multiple nodules in the liver by ultrasonography. Serum CEA was 7,387.9 ng/mL (normal 0-4.1 ng/mL) leading to a clinical impression of colonic carcinoma with liver metastasis. During the investigation, he developed acute abdomen caused by ruptured acute appendicitis. Malignant carcinoid tumor of the appendix, 1 cm in diameter and located proximal to the ruptured acute appendicitis, was identified. The tumor cells showed trabecular or insular growth pattern, some nuclear pleomorphism but typically fine nuclear chromatin, frequent mitoses and focal necrosis. They were immunoreactive for antibody to chromogranin, neuron-specific enolase, CEA, and cytokeratin. Tumor metastases were discovered in the liver, right lung, mediastinal and right supraclavicular lymph nodes. Electron microscopic study demonstrated pleomorphic neurosecretory granules of the midgut type of carcinoid tumor.

Acute abdomen is a challenge to first-line physicians because of frequently missed diagnoses and potential follow-on legal problems. Improving the management of these patients is of paramount importance, not only for saving lives, but also for reducing untoward problems associated with improper management. We present a case of a patient with acute abdomen due to intraperitoneal hemorrhage secondary to rupture of an ovarian tumor. Following emergency surgery, the patient was diagnosed with metastatic ovarian carcinoma. Because of improper preparation of the gastrointestinal tract, the patient underwent repeat exploratory laparotomy for colon carcinoma. Although this situation did not affect the outcome of the patient in this case, we are concerned that the patient did not benefit from a single operation, with primary complete excision of the tumor plus a colostomy. The outcome of patients with pelvic malignancy, especially those with ovarian carcinoma, might be better if initial surgery achieved optimal tumor debulking. This is possible with good preoperative planning and preparation. We emphasize the importance of preoperative preparation in spite of urgently needed care. Furthermore, every first-line physician should communicate the possibility of malignancy to patients and their families.
