We report a case of a 67-year-old Caucasian man with right upper quadrant abdominal pain. He underwent radiologic investigations that revealed a solid, focal mass, at the V hepatic segment. Because a definitive diagnosis, based on imaging appearance of the lesion, was impossible in our case, we performed a hystopathological investigation but the biopsies were inconclusive. So, the definitive di...

Mucinous ovarian tumors are the second commonest type of epithelial ovarian tumors. Most of these tumors are benign. Occasionally, these tumors may reach enormous dimensions without being symptomatic. We reported the occurrence of a huge benign ovarian tumor (mucinous cystadenoma) in Nnewi. The data were collected from history taking, clinical examination, laboratory investigation, ultrasonogra...

Intussusception is a rare cause of adult intestinal obstruction. Clinical manifestations are not specific, which makes a preoperative diagnosis difficult to establish and often causes delay. We report a case of acute intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy was performed revealing an obstructive mass at the ileocecal region resulting from an appendicular...

Primary retroperitoneal mucinous cystic tumors with borderline malignancy are rarely encountered. To date, only 12 cases have been reported in the literature. In this report, we present an additional case. A 65-year-old nulliparous woman complained of abdominal fullness. Her medical history included a hysterectomy and a single salpingo-oophorectomy performed 25 years prior to the present event....

BACKGROUND Krukenberg tumor is a metastatic ovarian tumor with primary focus usually seen in the gastrointestinal tract. Metastatic involvement of the ovary is an uncommon manifestation of malignancy. We report a [18F]-fluoro-2-deoxy-D-glucose positron-emission tomography/computed tomography (FDG PET/CT) appearance of solitary unilateral ovarian metastasis in a 44-year-old woman with a history ...

A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral stippled calcifications that demonstrate...

Primary mucinous adenocarcinoma of the eyelid is a very rare tumor arising from the eccrine sweat gland. It is locally invasive with a high rate of recurrence following removal. Although uncommon, metastasis to regional lymph nodes does occur, and there have been several reports of more distant metastasis. This tumor is characterized by the secretion of mucin. This mucin usually forms into pool...

A 59-year-old woman, suffering from back pain, visited a territory hospital. A large cystic tumor was found in the left upper abdomen by an abdominal ultrasonography. The patient was referred to our hospital, and computed tomography (CT) scan demonstrated a large unilocular cystic tumor with multiple septa, sized 15 cm in diameter, in the pancreatic tail (Fig. 1). No solid components of the cys...

BACKGROUND Elastography is widely used as a diagnostic tool for the diagnosis of invasive breast cancer. However, no study has yet shown if elastography for diagnosing mucinous carcinoma is as useful as that for diagnosing the usual invasive carcinoma. Mucinous carcinoma is considered as a soft tumor. In this study, we used elastography to evaluate the elasticity of mucinous carcinoma. METHOD...
