In addition to echinococcal cysts and mycetomas, a wide variety of disorders can occasionally produce an air meniscus sign on a chest radiograph. A proposed classification follows: I. Infections A. Lung abscess (with or without pulmonary gangrene) B. Fungus ball C. Bacterial ball D. Tuberculoma E. Blood clot in tuberculous cavity, Rasmussen aneurysm F. Echinococcal lung cyst II. Neoplastic A. Bronchogenic carcinoma B. Primary lung sarcoma C. Metastatic carcinoma, sarcoma to lung D. Bronchial adenoma E. Cystic hamartoma III. Developmental A. Bochdalek hernia (pseudocavity) IV. Traumatic A. Pulmonary hematoma V. Hemodynamic A. Congestive heart failure (with or without bullae)

A review of five patients who presented during a 3-year period with sarcoma arising in the inguinal canal demonstrated that the lesion is frequently mistaken for a hernia. In three of the patients incomplete excision of the inguinal mass resulted in spread of the lesion beyond the inguinal canal. The authors suggest that neoplastic lesions discovered in the inguinal canal should be evaluated by a small incisional biopsy followed by wide resection if sarcoma is confirmed on pathological examination. Preoperative irradiation and re-excision should be considered if widespread microscopic disease remains after excisional biopsy.

Two patients with true synovial cysts in atypical sites (internal compartment of knee and inguinal hollow) were investigated by radioarthrography, ultrasound and computed tomography imaging. The cyst in the hip region originated from a dilated serous bursa of the iliopsoas muscle that did not communicate or was no longer in communication with the joint. In contrast, the cyst of the knee appeared to be a lateral synovial capsule hernia. Positive diagnosis in both cases was dependent on combined ultrasound-CT scan imaging, this eliminating a tumor (sarcoma) of soft tissues. However, affirmation of the synovial origin (mesothelial covering of the wall) of the lesion was obtained by histology only, this allowing differentiation from a "capsular" (fibrous wall) cyst, which probably provokes similar ultrasound and CT scan images.

The aim of this study was to evaluate retrospectively the results of pedicled omentoplasty and split skin graft (POSSG) in reconstructing (full thickness) chest wall defects, and to define its role as a palliative procedure for local symptom control. Thirty-four patients with recurrent breast cancer (n = 25), radiation-induced necrosis (n = 5) or sarcoma (n = 4) of the chest wall were selected for the study. All patients underwent curative or palliative chest wall resection with reconstruction by pedicled omentoplasty and split skin graft (POSSG), between 1986 and 1994. Reconstructive outcome, complications, local tumour and symptom control following surgery was measured. The most common complication was shown to be partial necrosis of the omental flap (35%), followed by respiratory problems (26%), facial hernia (26%) and thoracic wound problems (15%), which were mostly treated in a conservative way (68%). The 3-year local tumour-free interval after POSSG in patients curatively treated for breast cancer is 16%. Seventy per cent of the patients who underwent palliative resection had longstanding relief of local pain, bleeding or foetor due to local tumour growth. It can be concluded that large (full thickness) chest wall defects after resection of local recurrence, primary malignancy or osteoradionecrosis of the chest wall can successfully be reconstructed by POSSG. Chest wall resection in patients treated with palliative intention is effective in local symptom control.

Sarcomas are neoplasms originating from connective tissues of any anatomical region; the sarcoma of spermatic cord is a rare neoplasm with only little more than two hundred cases described in the literature. Rhabdomyosarcomas in childhood and leiomyosarcomas in adults are the most frequent histological types. Liposarcomas, fibrosarcomas and osteosarcomas are less frequent. The spermatic cord liposarcoma originates from the spermatic cord fatty tissue and therefore it consist of adipose cells, fibroblasts and myxomatosus cells; such neoplasms are usually very well differentiated. Diagnosis is suggested by the appearance of a progressively enlarging mass and by echotomography which shows a solid or liquid mass of the spermatic cord. Therapy consists of surgical intervention (orchifunicolectomy) which also allows a correct histological diagnosis. The case of a 56 year-old male who underwent left orchifunicolectomy for a sarcoma of spermatic cord occasionally discovered during surgical repair of a left groin hernia is reported. Six months after the intervention the patient is in good condition and there is no evidence of relapse.

A case report is presented of Richter hernia of the stomach, after en bloc excision of multiple organs for sarcoma of the left upper quadrant of the abdomen. To our knowledge this is the first case reported in the literature. The conditions for the development of this hernia are : (1) the freeing of the greater curvature of the stomach (following removal of the spleen and tail of the pancreas); and (2) fascial dehiscence following a left thoracoabdominal incision involving rib resection.

Extratesticular lesions are common incidental findings at ultrasonography (US) among men and boys. Most lesions originate from or depend on the tunica vaginalis, a mesothelium-lined sac with a visceral layer and a parietal layer. The tunica vaginalis is formed when the superior portion of the processus vaginalis closes during embryologic development. Abnormal closure of the processus vaginalis leads to congenital anomalies of the tunica vaginalis, such as complete or partial patency of the processus vaginalis, spermatic cord hydrocele, and inguinoscrotal hernia. The proximity of the visceral layer to the testis explains the reactive involvement seen in epididymo-orchitis, with resultant pyocele or abscess formation. The tunica vaginalis also may be affected by inflammatory and traumatic disorders such as scrotal calculi, fibrous pseudotumor, or hematocele. These lesions manifest as solid or heterogeneous tumorlike masses. Lesions of mesothelial origin, such as adenomatoid tumor, tunica cyst, and mesothelioma, may involve the tunica vaginalis. Entrapped mesenchymal cells can lead to lipoma, leiomyoma, or sarcoma, although these tumors are uncommon in the tunica vaginalis. US is not useful for differentiating between benign and malignant tumors; however, some characteristic findings may help in planning the best surgical approach. Knowledge of the embryologic development, anatomic relationships, and pathologic disorders of the tunica vaginalis is essential to narrow the differential diagnosis of an extratesticular lesion. In most cases, US findings in combination with clinical assessment can indicate whether nonsurgical management or testis-sparing surgery is warranted.

Rhabdomyosarcoma (RMS) is a rare type of soft tissue sarcoma that mainly affects children. RMS in childhood commonly occurs in the head and neck, followed by the genitourinary tract. Primary pulmonary rhabdomyosarcoma (PPR) is extremely rare. We report a 31-month-old girl who had PPR with brain metastasis. The girl with wheezing and cough of 3 weeks and vomiting of 1 day was referred to a county hospital. At 9:00 a.m., a chest X-ray showed an abnormal shadow on a chest radiogram. Four hours later, in the process of computed tomography (CT) scan her condition deteriorated dramatically, while resuscitation efforts were unsuccessful. CT showed a solid mass in the right middle lung lobe. Subsequent autopsy revealed a large tumour located in the right middle lung lobe. Surprisingly, a mass of haematoma appearance was found in the left occipital lobe. Histological and immunohistochemical investigations of the masses established the diagnosis of PPR with brain metastasis. Herniation of brain, caused by the brain metastasis, was ascertained as the cause of death. The morphological and pathological findings are presented; the difficulty to diagnose PPR and the medico-legal implications are discussed.

Pelvic soft tissue sarcomas are rare tumors often presenting larger than other soft tissue sarcomas and can extend into the thigh through various anatomic routes. Surgical resection is the main modality of curative treatment. En bloc tumor excision with wide, negative margins may reduce the risk of local recurrence. Soft tissue sarcomas extending through the obturator foramen create unique challenges to operative management. This case report describes 2 cases of lipomatous lesions that extend through the obturator foramen, presenting as dumbbell-shaped lesions with large intra- and extrapelvis portions. One possible surgical approach performed in both patients is detailed with long-term follow-up. Postoperatively, 1 incidence of infection was reported. Functional outcomes were acceptable, with full restoration of ambulation without assistive devices in both cases and no hernia observed. Oncologic outcomes included locoregional recurrence in 1 patient at 24 months outside the radiation field. The ideal primary treatment for all localized soft tissue sarcomas, including those extending through the obturator foramen, is resection. However, the unique subgroup of obturator ring soft tissue sarcomas has undefined outcomes and complications. The authors' goal was to achieve en bloc resection with wide negative margins while preserving ipsilateral limb function. The surgical approach described in this case study offers a description of feasibility and discussion of theoretical and observed complications.

Malignant fibrous histiocytoma (MFH) is a common soft tissue sarcoma usually involving limbs and retroperitoneum. MFH of the rectus abdominis muscle is extremely rare. Surgery in similar cases leads to large abdominal wall defects needing reconstruction. Biological and synthetic laminar absorbable prostheses are available for the repair of hernia defects in the abdominal wall. They share the important feature of being gradually degraded in the host, resulting the formation of a neotissue. We herein report the case of an 84-year-old man with MFH of the rectus abdominis muscle which was resected and the large abdominal wall defect was successfully repaired with a biological mesh.
