Giant hamartoma of the oropharynx.

Giant polypoidal hamartomas of the pharynx and oesophagus are rare benign tumours of unknown origin, exceptionally arising from the oropharynx. We report the case of a 74-year-old man who developed sudden nausea and a foreign body sensation. Shortly afterwards he regurgitated a 25 x 3 x 1.5 cm pedunculated fleshy mass, still attached to the inside of his thorat. The patient was anaesthetised, the mass traced to the right tonsillar fossa and adjacent oropharyngeal wall. The pedicle was clamped and the lesion excised. Histology was consistent with a giant oropharyngeal hamartoma. We discuss the pathogenesis and potential complications of this condition. The literature is reviewed.

Primary malignant localized fibrous tumours of the pleura: clinical, radiological and pathological features.

Localized fibrous tumours of the pleura are rare primary pleural tumours that may exhibit malignant behaviour in approximately 20% of cases. The clinical, radiological and pathological features of five patients with malignant localized fibrous tumours of the pleura are presented. Clinical symptoms included chest pain, breathlessness and cough. Hypertrophic pulmonary osteoarthropathy (HPOA) occurred in one patient. Chest radiographs and thoracic computed tomography (CT) demonstrated large necrotic masses, with focal calcification and compressive atelectasis of the underlying lung. Histological features were variable and resulted in designation of these tumours as localized fibrous tumours of the pleura of low or high grade malignancy. The grading of malignancy did not correlate with final outcome, adequacy of surgical excision being the most important factor. These tumours have been referred to as benign pleural fibromas or localized mesotheliomas, but these names are inaccurate and the term localized fibrous tumour of the pleura is to be preferred. This term should also include tumours such as malignant fibrous histiocytoma of the pleura.

Functional aortic atresia in congenitally corrected transposition.

An infant with congenitally corrected transposition and severe regurgitation through the left atrioventricular valve presented with clinical and Doppler echocardiographic features of aortic atresia. This eventually proved to be functional. This clinical situation had not, to the best of our knowledge been previously reported before.

Persistent 5th aortic arch--a great pretender: three new covert cases.

Although persistence of the embryonic fifth aortic arch is considered a rare congenital malformation, analysis of the records of the cardiopathological collections of the Brompton and Killingbeck Hospitals reveals 6 examples in approximately 2000 specimens, an incidence amongst our material of 1 in 330. Since our review of the literature reveals only a further 13 described cases, we wonder if the condition may go unrecognized rather than being exceedingly rare. This possibility is further supported by the fact that 3 of our cases were incorrectly interpreted when initially described. In this report, we describe the details of 2 of these specimens and one other case that was not included in our earlier descriptions of this malformation. The first case had the persistent fifth arch as a conduit between the pulmonary and systemic circulations in the setting of aortic atresia with interruption of the aortic arch. The second case demonstrated a double lumen aortic arch, the fifth arch in this instance being an accessory systemic-to-systemic conduit. In the final case, the persistent arch was initially considered to represent an aorto-pulmonary window but review revealed an aortic to pulmonary conduit more in keeping with the presence of a fifth arch. We conclude that the powers of mimicry of this enigmatic structure may account for its apparent rarity.
