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.

AIMTo determine the incidence of adenocarcinoma of the prostate for patients undergoing radical cystoprostatectomy for bladder cancer in Taiwan.

METHODSA total of 248 patients in Taiwan who were histologically confirmed for transitional cell carcinoma of the bladder underwent cystoprostatectomy. Histopathologic evaluation of the prostate specimens sectioned at 5 mm intervals was performed.

RESULTSOf the 248 patients, 10 (4.03%) were found to have prostate cancer. Of the 10 cases of unsuspected prostate cancer, eight proved to be at stage T1 or T2, and two at T3 and T4, respectively. This rate of incidentally found prostate cancer amongst our bladder cancer patients appeared to be lower than that found in bladder cancer patients in similar studies in USA.

CONCLUSIONAlthough the incidence of incidental prostate cancer in patients in Taiwan with bladder cancer is not high compared with that in Western countries, we suggest that digital rectal examination and prostate-specific antigen (PSA) are important screening tools for men with bladder cancer, especially for those aged 60 years and older in Taiwan.

Unlike other non-gynecologic solid tumors, such as breast cancer, lung cancer, metastasis to bone from endometrial carcinoma is rare, metastasis to extremity is extremely rare. We report a 51-year-old multiparous woman with FIGO Stage IVb Grade 2 endometrial adenocarcinoma which metastasized to left lower extremity bone. She received an amputation of left lower extremity below the knees, and a total abdominal hysterectomy and bilateral salpingo-oophorectomy, and followed by systemic chemotherapy, radiation therapy to the pelvis and progestational agent. She had a complete response to above treatments, and disease-free survival for 10 months. After recurrence, she received chemotherapy, radiotherapy and progestational agent once again. She had lived 56 months and is still alive by the time of report. Metastasis of endometrial carcinoma to extremity bone can rarely occur and should be considered when the patient with endometrial carcinoma complained of unexplained pain and swelling associated with extremity bone.

OBJECTIVETo study the immunohistochemical expression and diagnostic significance of CD34 in brain tumors of patients with refractory epilepsy.

METHODSImmunohistochemical study for CD34 was performed on formalin-fixed paraffin-embedded tissue blocks of 54 cases of brain tumors occurring in patients with refractory epilepsy. The tumor types included ganglioglioma (GG, number = 21), dysembryoplastic neuroepithelial tumor (DNT, number = 8), tumors/lesions which had the transitional features that between glioneuronal hamartia and mixed neuronal-glial tumor (number = 21) and pleomorphic xanthoastrocytoma (PXA, number = 4). Cases of glioblastoma (number = 4) and oligoastrocytoma (number = 5) were used as controls.

RESULTSTwenty of the 21 cases of GG, 1 of the 8 cases of DNT, 16 of the 21 cases of tumors/lesions which had the transitional features and 3 of the 4 cases of PXA showed cytoplasmic and membranous positivity for CD34. The adjoining brain tissues in 9 of the 18 cases of GG, 6 of the 16 cases of tumors/lesions which had the transitional features and 1 of the 3 cases of PXA also expressed CD34. In contrast, only 1 case of glioblastoma showed membranous positivity for CD34.

CONCLUSIONSCD34 preferred to staining for GG and PXA. Which represent a valuable tool for distinguishing GG, PXA and DNT, oligoastrocytoma, glioblastoma.

The Lambert-Eaton myasthenic syndrome (LEMS) is typically recognized as a paraneoplastic syndrome associated with a small cell lung carcinoma (SCLC), whereas LEMS with other neuroendocrine lung tumors, including carcinoids or large cell lung carcinoma, are highly unusual. Here, we report a rare case of LEMS with atypical bronchopulmonary carcinoid tumor: A 65-yr-old man presented with progressive leg weakness and a diagnosis of LEMS was made by serial repetitive nerve stimulation test. Chest CT revealed a lung nodule with enlargement of paratracheal lymph nodes, and surgically resected lesion showed pathological features of atypical carcinoid tumor. We concluded that LEMS could be associated with rare pulmonary neuroendocrine tumor other than SCLC, which necessitates pathologic confirmation followed by aggressive treatment for optimal management in these rare cases.

OBJECTIVETo discuss the clinicopathological factors for lymph node metastasis (LNM) in early gastric cancer (EGC), including age, gender, location, size, macroscopic type, depth of invasion, histological type, and lymphatic invasion, and the regulation of LNM in EGC.

DATA SOURCESThe data used in this review were mainly from PubMed articles published in English. The search terms were "early gastric cancer" and "lymph node metastasis".

STUDY SELECTIONArticles were selected if they reported the clinicopathological factors and regulation of LNM in EGC.

RESULTSThe prognosis of EGC is better than advanced gastric cancer, with over 90% 5-year survival rate. The main risk factors for LNM in EGC are tumor size, macroscopic type, depth of invasion, histological type, ulceration, and lymphatic invasion.

CONCLUSIONSLNM in EGC is a critical factor for assessment of prognosis and determination of therapeutic strategy. Endoscopic mucosal resection or endoscopic submucosal dissection should be considered when patients have low risk of LNM.

Unusual presentation of localized gingival enlargement associated with a subjacent tumoural pathology is reported. The patient was a 55-year-old black male, whose chief complaint was a progressive gingival overgrowth for more than ten years, in the buccal area of the anterior left mandible. According to the clinical features and the radiological diagnosis of odontogenic keratocyst, a conservative surgery with enucleation and curettage was performed. Tissue submitted for histopathological analysis rendered the diagnosis of odontogenic myxoma. After 12-month of follow-up, no evidence of recurrence was found. Clinicians should be cautious when facing any gingival enlargement to avoid diagnostic pitfalls and to indicate the appropriate treatment.
