A littoral cell angioma (LCA) is a rare benign vascular tumor of the spleen. A 60-year-old man, with multiple nodules in imaging study and liver cirrhosis graded as Child-Pugh classification class A, was transferred for splenomegaly. A thrombocytopenia was found on hematological evaluation. Because there was no evidence of hematological and visceral malignancy, a splenectomy was performed for a definitive diagnosis. The histological and immunohistochemical features of the splenic specimens were consistent with a LCA. After the splenectomy, the thrombocytopenia recovered to the normal platelet count. There has been no previous report of a LCA combined with liver cirrhosis. Herein, the first case of a LCA in Korea, diagnosed and treated by a splenectomy, is reported.

Intussusception is primarily a disease of children, and is relatively rare in adults. Unlike childhood intussusception, adult intussusception has an identifiable leading lesion such as malignant or benign neoplasm. However, intussusception caused by hemangioma is very rare. There were few cases of small bowel intussusception caused by hemangioma in adults, but those reports were presented with abdominal pain. This report describes a 65-year-old female who suffered from small bowel intussusception caused by hemangioma presenting with intestinal bleeding. Upper gastrointestinal endoscopy and colonoscopy were performed, but bleeding focus was not found. Abdominal computed tomography showed the target sign of small bowel with a leading point of mass. This mass turned out to be a hemangioma after the small bowel resection. Therefore, small bowel intussusception by hemangioma should be also considered as a bleeding focus when an adult patient presented intestinal bleeding without bleeding focus in the stomach and colon. Herein we report a case of small bowel intussusception caused by hemangioma presenting with intestinal bleeding.

OBJECTIVETo investigate the clinicopathological characteristics, diagnostic criteria and differential diagnosis of placental chorioangioma.

METHODSTwenty-five cases of placental chorioangioma were analyzed for their clinical data, histomorphology and immumohisto chemical staining. Relevant literature was reviewed.

RESULTSThe average age of the 25 patients was 29 years. Fourteen patients had full-term pregnancy, 10 had preterm labor, and 1 had intrauterine fetal death. Nineteen patients had pregnancy complications. The tumors presented as red or dusty pink nodules with clear borders. The tumor size ranged from 1 to 16 cm. Microscopically, the tumors possessed abundant capillaries or cavernous blood spaces lined by hyperplastic endothelial cells. These cells were positive for CD34 and Ki-67 index < 10%.

CONCLUSIONSPlacental chorioangioma is a rare benign tumor of the placenta, and is associated with various pregnancy complications. Misdiagnosis of cell-rich type tumor should be avoided.

A pregnant lady in her third trimester presented with a rapidly growing right-sided nasal mass associated with epistaxis and nasal obstruction for six months. Examination showed a non tender, protruding mass completely occluding her right nostril. Wide surgical excision was done under anaesthesia. Histopathology revealed capillary haemangioma. In a gravid patient with a rapidly growing intranasal lesion, capillary haemangioma should be considered as a differential diagnosis.

PURPOSE: We aimed to evaluate the histologic and radiologic findings of vascular lesions after stereotactic radiosurgery (SRS) categorized as radiation-induced cavernous hemangioma (RICH). MATERIALS AND METHODS: Among 89 patients who underwent neurosurgery for cavernous hemangioma, eight RICHs from 7 patients and 10 de novo CHs from 10 patients were selected for histopathological and radiological comparison. RESULTS: Histologically, RICHs showed hematoma-like gross appearance. Microscopically, RICH exhibited a hematoma-like area accompanied by proliferation of thin-walled vasculature with fibrin deposits and infiltrating foamy macrophages. In contrast, CHs demonstrated localized malformed vasculature containing fresh and old clotted blood on gross examination. Typically, CHs consisted of thick, ectatic hyalinized vessels lined by endothelium under a light microscope. Magnetic resonance imaging of RICHs revealed some overlapping but distinct features with CHs, including enhancing cystic and solid components with absence or incomplete popcorn-like appearance and partial hemosiderin rims. CONCLUSION: Together with histologic and radiologic findings, RICH may result from blood-filled space after tissue destruction by SRS, accompanied with radiation-induced reactive changes rather than vascular malformation. Thus, the term "RICH" would be inappropriate, because it is more likely to be an inactive organizing hematoma rather than proliferation of malformed vasculature.

OBJECTIVE: To heighten the awareness of the facial nerve tumors. METHOD: The clinical data of twenty-three patients complaining of facial paralysis who were diagnosed postoperatively as facial nerve tumors were analyzed. The hearing assessment of all patients was based on pure tone audiometry at the frequency of 0. 5, 1, 2, 4 kHz. Temporal bone high resolution CT scan and temporal bone MRI with gadolinium enhancement were conducted on all patients. Facial nerve function was assessed with the House-Brackmann (HB) grading system. Facial electroneurography (ENoG) was conducted on 20 patients to quantify the degree of nerve degeneration preoperatively. The pathological types of tumor were determined by postoperative pathological reports. RESULT: Nineteen out of 23 cases presented hearing loss (82.6%), 10 cases suffered from tinnitus (43.5%), otalgia (17.4%) affected 4 cases, 3 cases manifested otorrhea (13.0%), and 2 cases presented vertigo (8.7%). Geniculate ganglion was the most commonly involved site (20 cases, 87.0%), followed by tympanic segments (18 cases, 78.3%), pyramid segment (16 cases, 69.6%), mastoid segment (10 cases, 43.5%), labyrinthine segment (9 cases, 39.1%), internal auditory canal segment and parotid gland segment (5 cases, 21.7%, respectively). Twenty-one cases (91.3%) of schwannomas, 1 case (4.3%) of neurofibroma and 1 case (4.3%) of hemangiomas were identified with histopathology postoperatively. The tumors were all completely excised, and the facial nerve function could recovered to HB III at the best after facial nerve repairment. CONCLUSION Facial nerve tumor is a rare and often misdiagnosed disease which was commonly manifested as facial nerve paralysis. Temporal bone CT and MRI can help to clarify the diagnosis preoperatively. Pure tone audiometry and electroneurography also plays a some certain roles in the diagnosis of facial nerve tumors. The tumors should be completely resected and the surgical approaches were determined based on tumor size, facial nerve function and preoperative auditory function.
