World Trade Center dyspnea: bronchiolitis obliterans with functional improvement: a case report.

Background: Bronchiolitis obliterans is a severe, often progressive, lung disease characterized by cough, exertional dyspnea, and airflow obstruction. It has been ascribed to specific causes such as lung or bone marrow transplant, medications for rheumatoid disease, and most recently in association with exposure to environmental agents.

Method: A 42-year-old, previously healthy New York City Highway Patrol officer who arrived at the World Trade Center (WTC), "ground zero," early on September 11, 2001 was evaluated.

Sebaceous carcinoma of the lung: histologic and immunohistochemical characterization of an unusual pulmonary neoplasm: report of a case and review of the literature.

Sebaceous neoplasms, including carcinomas, are tumors most often seen around the eye and eyelid. Cases of extraorbital sebaceous tumors associated with skin adnexa are less common. The parotid gland may also be a source for sebaceous neoplasms, and cases associated with minor salivary gland tissue have also been reported.
