Primitive neuroectodermal tumor (PNET) is anundifferentiated neoplasm arising from the germinal matrix of the primitive neural tube. It is predominantly an infratentorial tumor of childhood. Adult supratentorial PNETs are less common and extraneural metastasis are extremely unusual. Only five sporadic cases were reported in the international literature.1–6 In this article, we report a rare case...

INTRODUCTION An umbilical mass can be the first symptom of an intra-abdominal neoplasia, and this condition is also defined as Sister Mary Joseph Syndrome. CASE PRESENTATION An eighty-year-old patient presented with a complicated umbilical hernia. CT scan abdomen revealed a pancreatic neoplasm and an umbilical biopsy confirmed diagnosis of metastasis. Patient started chemotherapy by Oncologis...

Carcinoid tumours occur predominantly in the gastrointestinal tract and bronchial system of the lungs, but they can originate in less common anatomical sites such as the testes, which accounts for <1% of all testicular neoplasms. Carcinoid tumour is a rare and indolent neoplasm with the potential for distant metastasis. We report on a man with metastatic right testicular carcinoid tumour who ha...

Cutaneous metastasis is an uncommon manifestation of visceral malignancy. It occurs late in the course of the disease but can be a sign of an unknown neoplasm. A case of local cutaneous metastasis by contiguity with breast adenocarcinoma is reported. It presented as initial manifestation and main complaint of a 68-year-old woman, with no family history and negative screening tests for the disea...

In the Introduction of a recent review entitled ‘‘Exploring a New Twist on Tumor Metastasis,’’ Yang et al. state that, to understand the complex nature of the pathogenesis of cancer metastasis, ‘‘it is important to use experimental metastasis models that can recapitulate, at least in outline, the physiologic and pathologic conditions observed in human cancer patients.’’ The authors then state t...

Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral lesions such as sarcoidosis may also express somatostatin receptors, which may present a diagnost...

RATIONALE Gastrointestinal stromal tumor (GIST) is the neoplasm of gastrointestinal tract. PATIENT CONCERNS The patient complained about the retention of urinary. DIAGNOSES GIST. INTERVENTIONS radical prostatectomy and the imatinib therapy. OUTCOMES No recurrence and metastasis have been found during a 14-month follow-up. LESSONS comprehensive treatment is necessary for the GIST treat...

A 46-year-old woman presented with massive left temporal lobe intraparenchymal and diffuse subarachnoid hemorrhage on CT. Lack of enhancement excluded intermediate and high-grade primary tumor or metastasis as likely causes. At surgery, a fibrovascular left temporal lobe mass adherent to the dura proved to be a pleomorphic xanthoastrocytoma. The unusual hemorrhagic presentation of this typicall...
