BACKGROUND We report a case of primary mucinous cystadenocarcinoma of renal pelvis which radiologically resembled large multicystic mass in 45 years old man. CASE PRESENTATION The patient referred to our center with loin pain and progressive abdominal distention from 4 years ago. In the previous published literature, four cases of mucinous cystadenocarcinoma of renal origin have been publishe...

Schwannomas, or neurinomas, are generally benign, slow-growing, asymptomatic neoplasms originating from the Schwann cells of a nerve sheath. As a part of spindle cell mesenchymal tumours, schwannomas arising from the gastrointestinal tract (GIT) are unusual; however, when they occur, the most common site involved is the stomach, which represents 0.2% of all gastric tumours. We report the case o...

The en-bloc resection of neoplasms on the abdominal wall often causes extensive defects that are difficult to manage. The anterolateral thigh (ALT) flap is a widely used flap in reconstructive surgery of defects. In this article, we present a case using bilateral pedicle anterolateral thigh flaps combined with a surgical polymesh to repair a large defect (22 cm × 18 cm) caused by dissection of ...

Desmoid tumors are cytologically bland fibrous neoplasms originating from musculoaponeurotic structures throughout the body. The cause of desmoid tumors is uncertain, but may be related to trauma or hormonal factors, or may have a genetic association. These tumors can be found in some young women during pregnancy or just after giving birth. We report herein a case of desmoid tumor on the inner ...

Although alveolar echinococcosis (AE) can cause a serious disease with high mortality and morbidity similar to malign neoplasms. A 62-year-old woman admitted to a hospital located in Sivas, Turkey, with the complaints of fatigue and right upper abdominal pain. On contrast abdominal CT, a 54×70×45 mm sized cystic lesion was detected in the left lobe of the liver that was seen to extend to the po...

Gestational trophoblastic neoplasms (GTN) are proliferative degenerative disorders of placental elements and include complete or partial mole (90%), invasivemole (5-8%), choriocarcinoma (1-2%) and placental site tumor (1-2%). Chorioadenoma destruens is a trophoblastic tumor, characterized by myometrial invasion through direct extension or via venous channels. We present a case of invasive mole ...

Granular cell tumors (GCTs) are uncommon benign neoplasms deriving from Schwann cells of the peripheral nerve fibers. Although these tumors can be found anywhere in the body, the most frequent site is the tongue, followed by the chest wall and the arm. The abdominal wall is an extremely rare site for GCTs. These tumors are generally asymptomatic and have a slow growth rate. Today, thanks to the...

Context Mucinous cystic neoplasms are a family of morphologically similar tumors arising in the pancreas, ovarium, appendix, hepatobiliary tract, and more rarely in the retroperitoneum, testis, lung, breast, spleen, bowel, and mesentery. Case report A sixty-three-year-old male diagnosed with abdominal cystic lesions was referred to our hospital. Abdominal computed tomography revealed two cystic...

Malignant lymphomas involve the gastrointestinal tract either as primary neoplasms or as part of disseminated disease. Primary lymphoma of the colon is rare, constituting 0.4 % of all colonic malignancies. Non-Hodgkin lymphoma accounts for almost all colonic lymphomas.1-3 The signs and symptoms of colonic lymphoma are non-specific. The lack of specific symptoms can be the reason for delayed dia...

Lymphangioma is a benign tumor, which is a consequence of lymphatic malformation with blockage of lymphatic flow. Most lymphangiomas occur in the neck and axillary region, and < 1% occur in the mesentery or retroperitoneum. Lymphangiomas arising from the pancreas are extremely rare. We report the case of a 34-year-old woman with cystic lymphangioma of the pancreas without major symptoms or sign...
