Unilateral paralysis of the diaphragm not due to some obvious cause such as neoplasm or pulmonary tuberculosis has been said to be uncommon (Freedman, 1950). I present 16 such cases found during two years in a chest clinic. My purpose is to show that this is a comparatively common condition and that it may be caused by simple pulmonary inflammation (referred to in this paper as pneumonia). Clin...

Multiple primary or secondary malignancies after anticancer therapy were recently reported to be increasing in frequency. The authors describe a case of metachronous metastatic pulmonary basaloid carcinoma to the central nervous system that was discovered after chemotherapy and radiation therapy for cervical uterine carcinoma. Two different types of cancer developed within some interval. There'...

A 38-year-old non-smoker female with unremarkable history presented with an insidious onset of dry cough. Computed tomography revealed two solid round pulmonary lesions, curiously symmetrically located in the middle lobe and in the lingular segment, respectively (Fig. 1). Trans-bronchial needle biopsy was limited by a profuse bleeding and the diagnosis was inconclusive. The radiological differe...

It is extremely unusual for primary pulmonary lymphoma, an uncommon occurrence in any form, to be of T-cell origin and manifest as endobronchial lesion. Each these characteristics rare individually, so cases that combine them are exceptional. We report a patient whom anaplastic large cell neoplasm, presented with obstruction the left upper lobe bronchus, resulting atelectasis creating radiograp...

Pleuropulmonary blastoma (PPB) is a rare aggressive malignant tumor of infancy and early childhood. The tumor arises in the lung and pleura and is regarded as a pulmonary dysontogenetic or embryonic neoplasm. Four types are defined in literature. Type I PPB is a rare, cystic lung neoplasm in infants characterized by subtle malignant changes and a good prognosis. Recurrences after type I PPB are...

Vascular smooth muscle tumors are very rare. They can be benign or malign. Intravascular leiomyomatosis is a benign neoplasm that extends through the veins and caries significant morbidity. Angioleiomyoma is a benign neoplasm of the extremities that caries minimal morbidity. Vascular leiomyosarcomas are malign neoplasms derived from vascular smooth cells. They are usually localized to the infer...
