Although spontaneous resolution of MCC has been described for other head neck sites, there has not been any published case of nasal MCC regression. We present this rare case of nasal MCC with neck metastases and its regression.
Breast cancer rarely metastasises to the gastrointestinal tract. Lobular carcinoma more commonly metastasises to the uterus and appendages, peritoneum, and gastrointestinal tract than other types of breast cancer, while ductal carcinoma has a propensity to metastasise to the lungs, liver, and brain. We describe the case of a patient with no known history of breast cancer, whose primary presentation of lobular breast cancer was with malignant small intestinal and colonic strictures, with coexisting previously undiagnosed adenocarcinoma of the colon.
We describe a rare case of chondroblastoma of the acromion in a 29-year-old man. In addition to the radiological progression and confirmatory histological evidence of the lesion, the relevant and more unusual aspects of this tumour are discussed.
To investigate the effect of needle size and number of passes into a tumour mass on the cell yield from a fine needle aspirate, an in vitro study was undertaken in 19 consecutive tumours removed surgically for biopsy. Different needle sizes (23G, 21G, 19G) passed in random order, five, ten and fifteen times into the tumours, were compared. The type of tumour, needle size and number of passes independently and significantly influenced cell yield. A 21G(green) needle passed into the tumour at least 10 times was the most efficient in obtaining cells. This in vitro study could explain the variation in the reported accuracy of fine needle aspiration cytology from groups using different techniques and is perhaps one reason why the highest diagnostic accuracy and the lowest rate of unsatisfactory aspirates comes from a centre which uses a 21G needle and at least 10 passes through the tumour.
This is a case of a 71-year-old woman, who presented with a large abdominal mass. Microscopic examination revealed metastatic renal cell carcinoma in an otherwise massively enlarged benign ovarian tumour of mixed mucinous cystadenoma and Brenner tumour. Clinicopathological and radiological assessment together with a thorough evaluation of gross and histological features, including the use of immunohistochemical stains, is essential to confirm the diagnosis and rule out the possibility of primary clear cell carcinoma of ovary, as this has important prognostic and therapeutic implications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
