A 48-year-old woman presented with left abdominal pain and fullness. Computed tomography scan revealed a multicystic mass with multifocal mural nodules. Histologic examination showed a mucinous cystic tumor with cystadenoma, borderline malignant cystadenoma and cystadenocarcinoma, which were associated with sarcoma-like mural nodules (SLMNs) and multifocal anaplastic carcinoma. Mural nodules sh...
Infiltrative cerebral gliomas remain a neurosurgical challenge despite the latest achievements in neuroimaging techniques and microsurgical approaches. In this paper the authors present their experience in 85 cases of stereotactic biopsies performed for infiltrative, multicentric and deep-seated cerebral gliomas. The stereotactic and neuroimagistic tools used for these procedures included the L...
A new adjuvant therapy, individual adjuvant therapy (IAT), which is individualized according to the results of real-time reverse-transcription polymerase chain-reaction (RT-PCR) for O6-methylguanine-DNA methyltransferase (MGMT), was used to treat malignant gliomas. Immediately after the operation, mRNA expression for drug-resistance genes was investigated in frozen samples of malignant gliomas ...
Patients with human immunodeficiency virus infection are known to have increased risk of various neoplasms, including Kaposi sarcoma, which classically involves the skin and mucosal locations. The anaplastic variant of Kaposi sarcoma is rare and poorly documented in the literature. It is characterised clinically by a more aggressive behaviour and increased metastatic potential, and histological...
Primary cutaneous anaplastic large cell lymphoma is a T-cell malignancy with atypical CD30 positive lymphocytes. Pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. Careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...
Primary cutaneous anaplastic large-cell lymphoma is part of the spectrum of CD30+ lymphoproliferative cutaneous processes, characterized by single or multifocal nodules that ulcerate, are autoregressive and recurrent. Extracutaneous dissemination may occur, especially to regional lymph nodes. Histology shows a diffuse, non-epidermotropic infiltrate , anaplastic large lymphoid cells of immunohis...
AIM To study the outcome and recurrence in supratentorial anaplastic ependymoma. METHODS Sixteen cases of supratentorial anaplastic ependymoma were reviewed. The average age of presentation was 8.2 years ranging from 1 to 16 years of age. The mean duration between the onset of first symptoms to time of presentation was 4.2 months. Follow-up ranged from 5 to 58 months with a mean of 16.8 month...
BACKGROUND The clinical course of oligodendroglial tumors is variable and there is a lack of consensus with regard to precisely diagnose which minimal criteria are required to make a diagnosis of a high-grade oligodendrial tumor. The aims of the present study are to assess pathologic factors with prognostic significance, in addiction to clinical and neuroradiologic variables, in an attempt to i...
