In patients with multiple synchronous lung tumors, discrimination of multicentric lung cancers from intrapulmonary metastasis is important for treatment decision, but this is sometimes difficult. The aim of this study was to retrospectively distinguish multicentric lung cancers from intrapulmonary metastases in 14 such cases by loss of heterozygosity (LOH) and p53 mutational status. DNA was ext...

Aims—Human herpesvirus 8 (HHV-8) has been identified in multicentric Castleman’s disease and in angioimmunoblastic lymphadenopathies. However, the presence of the virus does not necessarily indicate an aetiological role in these conditions. This study investigates the cell types infected by HHV-8 in Castleman’s disease and examines the correlation between HHV-8 and Castleman’s disease lymph nod...

BACKGROUND This study was conducted to investigate the clinical advantages of modified double ring areola incision (MDRAI) compared to ordinary areola incision (OAI) in multicentric breast fibroadenoma in women. METHODS Sixty cases of multicentric benign breast tumor were recruited from the First Affiliated Hospital of Bengbu Medical College from January to December 2016. The cases were divid...

AIM few data have been published regarding the causes of synchronous lesions in patients with colorectal cancer. The aim of our study was to identify potential factors that might be implicated in the development of multicentric lesions, since this knowledge could be useful for tailored follow-up once initial synchronous lesions have been removed. METHODS we retrospectively reviewed 382 colore...

Multicentric Castleman's disease (MCD) is a rare lymphoproliferative disorder found with a higher frequency in HIV-seropositive patients. Human herpes virus 8 is found in virtually all cases of HIV-associated MCD. The majority of cases of MCD in patients with HIV are also associated with Kaposi's sarcoma. The dysregulated production of human IL-6 is thought to be an important factor in the path...

Multicentric Castleman's disease (MCD) is a rare lymphoproliferative disorder. It is found with higher frequency in patients with HIV infection, with systemic symptoms and poor prognosis. We present the case of a 32-year old man with HIV disease, Kaposi's sarcoma, lymphadenopathy, fever and hemolytic anemia. A diagnosis of Castleman's disease is confirmed through biopsy and treatment is often b...

Posterior fossa glioblastoma multiforme is a very rare childhood tumor with an extremely poor prognosis. There are only few cases of primary cerebellar glioblastoma described in the literature, and primary cerebellar glioblastoma presenting radiologically as a cerebellopontine angle mass lesion has not been reported previously. The authors report a multicentric glioblastoma multiforme in an 11-...

Bone epithelioid angiosarcoma is rare and generally shows positive immunostaining for epithelial markers. Multicentric bone epithelioid angiosarcoma is easily misdiagnosed as carcinoma, including metastatic carcinoma, multiple myeloma, and multiple lymphoma of bone. This article describes a case of multicentric bone epithelioid angiosarcoma. The patient was first misdiagnosed as having metastat...

A patient with multiple sclerosis and a multicentric anaplastic astrocytoma is described. The evidence suggests that the relationship is not coincidental and that the astrocytomas originate in multiple sclerosis plaques.
