Aspiration of thoracic masses and fluid collections under guidance of ultrasonography.

Successful ultrasonic detection and fine needle aspiration of pleural effusions, loculated fluid, and peripheral lung masses were done in 115 patients. No complications, eg, pneumothorax or hematoma, were caused by the fine needle aspirations. There was no false-negative or false-positive cytology because of excellent localization by ultrasound and adequate tissue samples. This series shows ultrasonography to be a valid method of evaluating chest lesions seen to be peripheral on chest roentgenograms. The cystic or solid nature of these lesions was determined; however, we experienced difficulty in differentiating small amounts of loculated fluid from pleural thickening in a few cases. Difficulties were also noted with a few small peripheral tumors that appeared to be cystic on ultrasonography but were proven to be solid by fine needle aspiration. These problems can be resolved by an experienced sonographer using equipment with higher resolution, but we did not hesitate to do fine needle aspiration in such circumstances.

Surgical implications of actinomycosis.

We have described two patients with abdominal actinomycosis, one with extensive intra-abdominal and thoracic disease mimicking metastatic carcinoma, and the other having the rarely described clinical entity of retroperitoneal disease without evidence of intra-abdominal involvement. Both patients responded well to appropriate therapy, but had unnecessary surgical procedures. The surgeon's role in cases of actinomycosis should be limited to the provision of a diagnosis when necessary.

The chyloesophageal fistula. A new approach to thoracic duct drainage.

The main reason for the virtual abandonment of external thoracic duct drainage as an immunosuppressive measure is not its lack of efficacy, but the time-consuming technical problems of maintaining cannula patency and replacing the large obligatory losses of fluid and protein. In an effort to overcome these problems we have devised a method of diverting thoracic duct lymph internally into the esophagus of the sheep, our hypothesis being that fluid and protein should be resorbed, but lymphocytes and antibodies destroyed. By isolating that part of the venous system into which the thoracic duct drains and anastomosing this conduit to the cervical esophagus a chyloesophageal fistula was created. A mean patency of 19 days was demonstrated radiologically and there was a reproducible peripheral blood lymphopenia of over 50% of preoperative values at 4 weeks. Although plasma albumin levels fell from 37 g/L to 29 g/L at 1 week, they remained stable thereafter. No parenteral fluid or protein was administered, yet the animals remained well with no significant weight loss or overt signs of dehydration or hypoproteinemia. Skin allograft mean survival time was prolonged from 9 to 11.8 days (P less than 0.01).

Multiple giant disseminated pyogenic granuloma in three patients burned by boiling milk.

BACKGROUND: Pyogenic granuloma is a common benign skin tumor. The multiple disseminated form of the disease is relatively rare. METHODS: We examined three patients who developed giant pyogenic granuloma after burns from boiling milk. The patients were a 1.5-year-old boy, a 5-year-old girl, and a 35-year-old woman, All three patients had second-degree burns over their face and trunk. RESULTS: In these patients, pyogenic granuloma had developed over the previously burned areas 2-3 weeks after exposure. The general condition of the patients remained good and all lesions involuted spontaneously. In a 6-month follow-up period no relapse of the lesions was seen. CONCLUSIONS: The cause for development of multiple giant pyogenic granulomas after burns from milk remains unknown, but milk proteins or other components of milk, microorganisms, or the burn itself may be causative factors.

Multifocal mesenchymal hamartoma of the chest wall.

Chest wall hamartomas are extremely rare. Frequently mesenchymal hamartomas are presented as a single mass and contain some primitive mesenchymal elements such as chondroid and trabecular bone structures. A 60-year-old man presented to hospital with chest pain. Thirteen years earlier, his CXR and thoracic CT showed three masses on the right and two masses on the left, but he had not received any treatment thereafter. His CT showed the same masses present 13 years earlier, but they were bigger and right thoracotomy was undertaken. At thoracotomy, two sections of the mass in the right posterior mediastinum and one section of the mass in the right apex were excised. They had an occasional bloody appearance and contained small cystic areas, and some areas were extremely hard. Microscopic examination showed that the lesions consisted of mature adipose tissue, a large number of veins of different diameters and collagen tissue. Besides, primitive mesenchymal elements, lymphoid cell accumulations and trabecular bone structures were seen focally. Bilateral chest wall hamartomas are extremely rare and may be confused with malignancy.

Bilateral epididymal sarcoidosis presenting without radiographic evidence of intrathoracic lesion: Review of sarcoidosis involving the male reproductive tract.

Sarcoidosis is a multisystem disorder that rarely involves the genitourinary tract. To date, only 59 cases of histologically proven sarcoidosis involving the male reproductive tract have been reported in the literature. We present here a case of bilateral epididymal sarcoidosis without radiographic evidence of intrathoracic lesion. A 46-year-old man presented with a one-week history of painless bilateral scrotal swellings. Physical examination detected multiple elastic firm nodules on both sides of the scrotum which showed no tenderness. The nodules seemed to involve the entire bilateral epididymides. Some irregularly shaped hypoechoic masses in the bilateral epididymides were identified on gray scale ultrasonography. On magnetic resonance images, the bilateral epididymides were seen to be enlarged, heterogeneous and nodular without any signs of testicular involvement. The lesion showed a slightly high signal intensity on the T2-weighted image. Pathological evaluation following bilateral epididymectomy found non-caseating epithelioid cell granulomas with giant cells in epididymal tissue, thus confirming a diagnosis of sarcoidosis. Gallium-67 scanning showed additional small hot spots in the anterior chest wall and extremities. Open biopsy of a superficial papular lesion in the dermis of the right upper arm was performed and pathological findings indicated sarcoid granulomas. This report also includes a review of the literature pertaining to sarcoidosis of the male reproductive tract.

Chest wall actinomycosis in association with the use of an intra-uterine device.

A 31 year old woman presented with a chest wall abscess due to Actinomyces israellii and Porphyromonas asaccharolytica (previously Bacteroides asaccharolyticus). She was a long-term user of an intra-uterine device (IUD) and, although asymptomatic, had radiological evidence of pelvic infection. Actinomyces-like organisms were seen on cervico-vaginal smears. The abscess was surgically drained, the IUD removed, and a prolonged course of amoxycillin/clavulanic acid given.
