Osteophytes may be a rare cause of recurrent pleural effusions.

We report a rare case of a 59 year-old female, who was admitted to the hospital because of a recurrent right-sided pleural effusion. The initial work-up was non-diagnostic. The diagnosis was finally confirmed following medical thoracoscopy, where an osteophyte of a rib was found to protrude sharply into the thoracic cavity. Chronic inflammatory changes of the pleura suggested mechanical irritation due to long lasting friction between this bony structure and the underlying lung. This is the first report where an osteophyte seems to be implicated in pleural pathology. A brief review of the available data from the literature is presented to further support our results.

Primary pulmonary melanoma diagnosis: the role of immunohistochemistry and immunocytochemistry.

We report a rare case of a primary melanoma of the lung initially presenting with haemoptysis, which was diagnosed using 2 new immunohistochemistry markers and cytology with immunocytochemistry. A 67-year-old male underwent repeated major lung resections and died because of early recurrences of a primary pulmonary melanoma as detailed study excluded other primary foci. The diagnosis of the patient's last recurrence was achieved on a fine needle aspiration (FNA) specimen with immunocytochemistry. To the best of our knowledge this is the first case of primary pulmonary melanoma diagnosed by immunocytochemistry on FNA material.

The prevalence of congenital bronchial atresia in males.

BACKGROUND: Congenital bronchial atresia is a rare anomaly, which usually occurs in adulthood as an incidental finding on routine chest radiograph. METHODS: The purpose of the study was to retrospectively evaluate the cases that were diagnosed in our hospital, from January 1995 to March 2003, to estimate the prevalence of this disorder and to determine the diagnostic studies of choice, according to the existing literature. Since the main portion of the male population of our country is referred to our hospital for screening soon after their enrollment in the army, epidemiological data can be easily estimated for many congenital anomalies occuring in adulthood, such as bronchial atresia. RESULTS: We found seven patients with Congenital Bronchial Atresia and the prevalence of this disorder was estimated at 1.2 cases per 100,000 in males. The chosen diagnostic procedure is computed tomography of the chest with high-resolution scans. Bronchoscopy would only exclude serious alternative diagnosis and prevent unnecessary surgical interventions. CONCLUSIONS: Congenital bronchial atresia is a rare anomaly, with a mild clinical course. The diagnosis is made radiologically, the HRCT of the chest being the procedure of choice. Bronchoscopy should be performed to exclude any endobronchial lesion due to a different disease entity and to prevent unnecessary surgical intervention in an otherwise asymptomatic individual.

The varied manifestation of pulmonary artery agenesis in adulthood.

OBJECTIVE: Unilateral pulmonary artery agenesis (UPAA), a rare congenital anomaly that is frequently associated with other cardiovascular abnormalities, is usually diagnosed in childhood. Most patients who have no associated cardiac anomalies have only minor or absent symptoms and survive into adulthood. The conditions of such patients are frequently misdiagnosed in adulthood. In this report, we describe six patients with UPAA in whom the diagnosis was first established in adulthood. The varied clinical presentation of these patients is reviewed and the relative effectiveness of a variety of diagnostic tests is compared. SUBJECTS AND METHODS: During the period January 1987 through December 1990, six male patients, aged 17 to 20 years, were found to have UPAA at the time of their medical screening for enrollment into the armed forces. The diagnosis was based on history, clinical and imaging examinations, including chest radiography, ventilation-perfusion lung scan, digital subtraction angiography (DSA), computed tomography (CT), and magnetic resonance imaging (MRI). RESULTS: In four of the patients, the UPAA was on the left side and in two it was on the right. A right aortic arch was present in three patients and other cardiovascular anomalies were found in three. Pulmonary function studies showed a mild restrictive pattern in four. In contrast to previous reports, the ventilation scan showed a diminished "wash in" and "equilibrium" phase without a delayed "wash out" phase on the affected side in all patients. Selective bronchography through the fiberoptic bronchoscope revealed ipsilateral mixed-type bronchiectasis in two of four patients studied, a finding of clinical significance that has not been described previously. In all cases, the diagnosis was made by DSA. CT of the thorax (n = 6) and MRI (n = 4) were diagnostic in all cases in which they were performed, but added no significant information. CONCLUSION: UPAA is frequently misdiagnosed in adulthood and is often not considered in the differential diagnosis of the unilateral hyperlucent lung. Clinicians and radiologists should be aware of the possibility of undiagnosed cases in adults, with many atypical characteristics.
