A muscle mass in a patient with polymyalgia rheumatica.

We report the extremely uncommon case of a 77-year-old woman in whom a tumor found to be a melanotic schwannoma, arising from the right rectus abdominis muscle, was detected during investigation for a rheumatic disorder, finally identified as polymyalgia rheumatica (PMR). Tumors of this type most commonly occur in spinal nerve roots, and their clinical behavior is very difficult to predict. As far as we are aware, this is the first reported case affecting the aforementioned site. The challenging issue in this case concerns the possible link between the 2 clinical conditions, in particular the development of PMR as a paraneoplastic syndrome. Although such an association has not been reported, PMR is included among the rheumatic disorders reported to be associated with malignancies and occasionally with benign tumors. However, given that tumor resection did not result in remission of PMR and symptoms improved rapidly with prednisone, it seems likely that the above disorders might simply coexist.

Large tension bronchogenic cyst in an adult mimicking the Swyer-James syndrome.

A case report of a large tension bronchogenic cyst in an adult that appeared as the Swyer-James/Macleod's syndrome is presented. Despite the thorough preoperative examinations the diagnosis was confirmed only after exploratory thoracotomy and histopathological study.

Intramural bronchogenic cyst of the oesophagus: a rare entity.

Bronchogenic cysts are congenital cystic lesions of foregut origin, usually intra-pulmonary or mediastinal in location. Peri-oesophageal bronchogenic cysts are rare, while intra-oesophageal cysts are almost always considered as enterogenous owing to their location and their composition. We report here an unusual case of a young adult with an intramural bronchogenic cyst causing dysphagia. Despite the fact that the cyst was completely embedded in the oesophageal wall, the pathological findings revealed the respiratory origin of the cyst. An extramucosal excision of the cyst was performed establishing the diagnosis and alleviating all our patient's symptoms.
