Six cases of the rarely encountered, advanced tumours of the larynx treated in ENT Clinic of Pomeranian Medical Academy in Szczecin are presented: chondroma, rhabdomyosarcoma, neurinoma, cylindroma and 2 cases of granular cell tumour. There were certain diagnostic difficulties in rhabdomyosarcoma and chondroma cases. The immunocytochemical investigations were of decisive significance in differential diagnosis of the larynx sarcoma. In the case of chondroma there were problems with biopsy taking the tense tissue of the tumour was compressing the subglottic space. The radiological examinations turned out to be very helpful in this case. All patients were treated by surgery, two of them with rhabdomyosarcoma and cylindroma were treated by irradiation too. Observation periods were from 0.5 to 10 years. The oncological and functional results in 4 cases after partial laryngectomies turned out to be satisfactory. All larynx activities were preserved. The patient with sarcoma of the larynx died 6 years after diagnosis of neoplasm. Finally author discuss diagnostic problems and methods of treatment.

We report the case of a 43-year-old man who presented with painless proptosis of the right eye of 6 weeks' duration. Examination demonstrated a tense right orbit and decreased vision and extraocular motility bilaterally. Diagnostic evaluation included computed tomographic imaging of the head and orbits, a therapeutic trial of high-dose systemic corticosteroids, and orbital biopsy, which revealed the presence of metastatic adenocarcinoma. The primary tumor was found to be an estrogen-receptor-positive, infiltrating ductal adenocarcinoma of the right breast. Therapy included lumpectomy of the breast mass, orbital irradiation, and hormonal therapy. Metastatic carcinoma of the breast should be considered in the differential diagnosis of orbital neoplastic disease in the male patient.

A 16-year-old boy was submitted to a cardiac examination after an episode of faintness. A transthoracic echocardiogram was performed, which revealed a very mobile multicystic tumor attached to the mitral valve. A small solid mass adherent to the cysts was better defined by transesophageal echocardiography. The patient was submitted to cardiac surgery consisting of tumor resection and a mitral prosthesis implant. The surgery was successful. The tumor consisted of three bright red tense cysts with hematic content, each 1 to 2 cm in diameter. The cysts were coalescent and adherent to a solid mass attached to the posterior papillary muscle head. Histopathologic examination revealed a hamartoma with a cystic part composed of the proliferation of myofibroblast cells in a stroma with vessels, collagen, and elastin fibers. Valvular hamartoma with blood cysts is a very rare cardiac tumor both for its histopathology and its localization.

Reports of angiosarcoma arising in the central nervous system are rare. The authors present the case of a 30-day-old infant with clinical manifestations of projectile vomiting and tense anterior fontanelle resulting from a left frontotemporal tumor. Total excision of this highly vascular, well-circumscribed tumor was performed without incident, and histopathological examination revealed a malignant angiosarcoma. Immunohistochemical reaction of the neoplastic cells was diffusely positive for endothelium-specific antigens including factor VIII-related antigen, CD31, and CD34. The final diagnosis of congenital primary cerebral angiosarcoma was thus confirmed. The patient's postoperative course was uneventful, and he was discharged 2 weeks after the operation. He was in good condition with no sign of recurrence after 11 months; follow-up computerized tomography, magnetic resonance (MR) imaging, and abdominal ultrasonography studies demonstrated no tumor regrowth. The characteristic findings for this tumor on MR imaging, the immunohistochemical findings, and surgical outcome are discussed.

We report an unusual case of T-cell lymphoma presenting as ascites. A 72-year-old HIV-negative woman was admitted to our hospital for abdominal discomfort associated with increasing abdominal girth over the course of 1 month. Physical examination showed a tense and distended abdomen and edema of the lower extremities. There was no hepatosplenomegaly or lymphadenopathy. A computed tomographic scan of the abdomen and chest showed massive ascites and pleural effusions, but there was no evidence of tumor masses or lymph node enlargement. The cytospin prepared from the peritoneal fluid was hypercellular and composed of a population of monotonous, large cells containing fine chromatin. No herpesvirus-8 (HHV-8) DNA was detected by polymerase chain reaction in the cells. Immunohistochemistry showed the neoplastic cells to be CD3+, CD4, CD7+. CD8-, CD34-, CD56, and TCR-alphabeta+. Repeated cytogenetic studies showed common abnormalities of del(1) (p11p22), +i(7)(ql0), and t(11:14)(q23;q11). The morphologic and immunologic findings were suggestive of peripheral T-cell lymphoma (PTCL), unspecified. This case suggests that some PTCLs with clonal chromosomal aberrations can exhibit peculiar serosal spreading in the absence of HHV-8 infection.

Neonatal brain tumor is a rare clinical entity. The initial presentation in affected newborn infants is often subtle, nonspecific, and rarely includes focal neurologic signs. We report a 2-day-old male infant with congenital oligodendroglioma with initial manifestations of hyperbilirubinemia. Phototherapy was started immediately after admission. Because of a tense anterior fontanel and irritable crying, head ultrasonography, computed tomography, and magnetic resonance imaging were performed and revealed a heterogenous brain tumor in the left temporoparietal lobe. Craniotomy and tumor evacuation was performed, and WHO grade III anaplastic oligodendroglioma was confirmed by the pathologic studies. The patient was discharged 3 weeks later, and outpatient follow-up examination revealed a normally developed infant at 6 months of age. The cause of jaundice was thought to be secondary to tumor hemorrhage, which was not infrequent in neonatal brain tumor.

Compartment syndrome is classically considered a complication of a musculoskeletal injury. Recent research has confirmed the abdomen as a potential compartment with the capability to cause life-threatening local and systemic manifestations. Abdominal compartment syndrome (ACS) is precipitated by an acute increase in abdominal contents volume with resulting intraabdominal hypertension. Presenting signs of ACS include a firm tense abdomen, increased peak inspiratory pressures, and oliguria, all of which improve after abdominal decompression. Patients at risk for ACS include trauma (blunt or open), retroperitoneal hemorrhage, massive fluid resuscitation, pancreatitis, pneumoperitoneum, and neoplasm. Surgical decompression is the treatment of choice. The perianesthesia nurse plays a critical role in the team managing a patient at risk for abdominal compartment syndrome through intraabdominal pressure monitoring, wound care, and end organ perfusion support.

Our study compares deglutition between a group who had undergone total esophagopharyngolaryngectomy and a group who had esophagectomy and partial pharyngectomy with preserved larynx, after reconstruction of the upper digestive tract with pedicled colon interposition. In four patients the laryngeal structures could be preserved (three caustic burns and one proximal esophageal tumor). Six patients underwent a total laryngopharyngectomy for large pharyngeal tumors. Swallowing was assessed by a questionnaire, clinical examination, and videofluoroscopy. All patients had normal intake of semisolid foods and fluids. All patients but three experienced some feeling of "narrowing" of the tract: four at the level of the hypopharynx, two at the oropharyngeal level, one at the oral level. In the laryngectomy group, solid food caused some degree of delayed swallowing in three patients. Dumping occurred in one case out of the nonlaryngectomy group. On clinical examination a tense motility in all laryngectomy patients appeared, food remnants in five and repeated swallowing movements in four. The videofluoroscopy confirmed repeated swallowing movements and presence of residual food in the oral cavity. Temporal stagnation occurred at the anastomosis site in all patients and in two patients at a place of colon redundancy. Colon interposition is a reliable reconstruction and gives the possibility of a good functional outcome. Although preservation of the larynx facilitates swallowing even in this reconstructive procedure, it may be better to perform a total laryngopharyngectomy and colon interposition in oncological cases where the pharyngeal remnant is borderline for primary closure.

Posterior fossa tumors are commonly associated with obstructive hydrocephalus. Relieving the raised intracranial pressure by draining the cerebrospinal fluid presents the possibility of reverse herniation of the brain. A 5-year-old male child with a diagnosis of posterior fossa space-occupying lesion and hydrocephalus was scheduled for craniectomy in the prone position. After craniectomy, the surgeons placed an intraventricular shunt catheter to drain out cerebrospinal fluid in an attempt to reduce the tense brain so as to facilitate easy dissection of the tumor. The patient had sudden and severe bradycardia followed by asystole. A diagnosis of reverse coning was made. Immediately, the surgeon injected 10-15 mL normal saline into the ventricles. There was a spontaneous return of the sinus rhythm and the rest of the course of surgery was uneventful. We present this case showing a rare phenomenon and its successful management.

The abdominal compartment syndrome has received considerable attention only recently. It may be defined as adverse physiologic consequences that occur as a result of an acute increase in the intraabdominal pressure. The most common causes of ACS are haemorrhage, visceral oedema, pancreatitis, bowel distension, venous mesenterial obstruction, abdominal packs, tense ascites, peritonitis, tumor. The mostly affected organ systems include cardiovascular, pulmonary, renal, central nervous and splanchnic. The diagnosis depends on the recognition of the clinical syndrome followed by an objective measurement of intraabdominal pressure, preferably that of the urinary bladder. The treatment consists of adequate fluid resuscitation and surgical decompression when necessary. (Tab. 1, Ref. 29.).
