A patient is described with a unilateral pleural effusion persistently infected with Salmonella enteritidis. The infection was eventually eradicated with ciprofloxacin. A computed tomographic scan and mediastinal lymph node biopsy demonstrated an underlying small cell bronchogenic carcinoma.

Metaplastic carcinoma of the breast refers to a heterogenous group of mammary carcinomas that contain a mixture of various cell types, including squamous cells, spindle cells and/or a mesenchymal component, such as bone or cartilage. To the best of our knowledge, the clinical course of a tumour that has undergone a transformation from one type of metaplastic carcinoma to another subtype has not...

Forty-six cases of primary bronchogenic carcinoma occurring in patients with other unilateral pleuropulmonary diseases were studied. In 37 cases (80-4%) carcinoma developed in the previously healthy lung. All but one squamous-cell carcinoma and all of five undifferentiated small-cell carcinomas developed in the previously healthy lung while 7 of 15 adenocarcinomas were in the lung with impaired...

BACKGROUND Pancreatic adenosquamous carcinoma (PASC) is a rare subtype of pancreatic cancer characterized by a dual histological component and aggressive behavior. This form is not well known, its histogenesis is uncertain, and there are different opinions on the diagnostic histopathological criteria. The differential diagnosis with more common ductal adenocarcinoma, squamous cell carcinoma, sq...

Background & objective: The histologic distinction of small cell from non-small cell lung carcinoma and correct identification of all subtypes of lung carcinoma are very important in treatment management. The main method for histologic classification of lung tumors is based on morphology. However, in small bronchoscopic biopsies in par...

We report a case of a patient with a previous coronary artery bypass graft who presented with chest pain and was found to have adenosquamous carcinoma encasing the left internal mammary graft to left anterior descending artery – the only viable vessel to his coronary circulation. Adenosquamous carcinoma, a rare lung cancer with a poor prognosis, causing obstruction of a bypass graft has not bee...
