Diagnostic value of bronchoscopy, CT and transbronchial biopsies in diffuse pulmonary lymphangiomatosis: case report and review of the literature.

The authors present the case of a 48-year-old man with diffuse pulmonary lymphangiomatosis. This rare lymphatic disorder is characterized by proliferation of anastomosing lymphatic vessels varying in size. Clinical presentation and imaging findings are highly suggestive. Bronchoscopic examination of this patient showed, for the first time to our knowledge, vesicles disseminated throughout the bronchial tree. Histopathological examinations are necessary to differentiate lymphangiomatosis from lymphangiectasis. The diagnosis can be made by transbronchial biopsy without performing open lung biopsy which was, until now, considered necessary for diagnosis.

[Black oesophagus, a rare event in intensive care unit].

We report a new case of acute necrotizing oesophagitis, diagnosing on a patient hospitalised in intensive care unit. This pathology is still a rare event; the definition excludes patients with a history of recent caustic ingestion. Oesophageal necrosis can be diagnosed at endoscopy by the presence of black necroting appearing oesophagus. Contrary to the caustic oesophagitis whose treatment is often surgical, treatment of the acute necrotizing oesophagitis is primarily medical. The prognosis for patients who develop acute necrotizing oesophagitis is generally poor, even if one can hope for the cure without after-effect of it.

[Life-threatening cellulitis, or Fournier's gangrene of the perineum].

The global mortality for Fournier's gangrene is one in five. In half the cases, the infection is polymicrobial with either anaerobes or gram negative bacilli. Factors which worsen prognosis include renal insufficiency, streptococcal infection, or need for hospital admission. Diagnosis must be prompt and treatment multidisciplinary involving the surgeon, intensivist, and infectious disease specialist; early and adequate surgical debridement must be accompanied by well-chosen antibiotics and hyperbaric oxygen therapy. Post-debridement therapy requires a long period of dressing changes and skin grafting to achieve final wound closure. This is an aggressive disease with a high mortality, but the depth and extent of invasive infection does not determine prognosis; the first priority is prompt and wide surgical excision/debridement of infected tissues to pre-empt the development of systemic sepsis; this should not be deferred while arranging transfer to a facility with a hyperbaric chamber.

Soft tissue tumors following traumatic injury: two observations of interest for the medicolegal causality.

Two cases of tumors of the soft tissues developing at the site of a previous traumatic injury occurring a few years earlier are reported. One was finally diagnosed as aggressive fibromatosis and the other as low-grade fibrosarcoma. Among the pathogenic mechanisms and the etiologic factors involved in such tumors, the posttraumatic causality is discussed, and in addition to the initial trauma, the role of iterative surgery in the first case and mineral muscular inclusions in the second case are examined. The different therapeutic approaches of such lesions are also reviewed.

[Necrotizing cervico-mediastinal cellulitis. Apropos of 3 cases].

OBJECTIVE: To outline the most appropriate treatment of descending necrotizing mediastinitis. MATERIALS AND METHODS: Three adult patients had mediastinitis occurring from a descending odontogenic infection in one case and oropharynx infection in two cases. All patients underwent extensive surgical debridement and a cervicomediastinal drainage through a cervical incision. All patients survived. DISCUSSION: Soft-tissue infections of the neck with mediastinitis demand early diagnosis aided by CT scan in order to decrease their threat to life. Extensive surgical debridement and a cervico mediastinal drainage through a cervical incision is adequate when mediastinitis is limited to the upper mediastinum. Thoracotomy has to be performed when the process spread below the carina. Patients must be treated initially aggressively with the aid of multidisciplinary support team (intensive care physicians, thoracic and head and neck surgeons). Early surgery must treat both neck and mediastin. While usually associated with greater than 40% mortality, all the patients in this series survived.

[Specific respiratory manifestations associated with hemorrhagic rectocolitis. Analysis of a case and review of the literature].

Respiratory impairments occurring as systemic manifestations of ulcerative colitis are often misinterpreted. We report a case of chronic productive bronchitis associated with ulcerative colitis; symptoms appeared after colectomy. Clinical features distinguished it from common chronic bronchitis: it occurred in a woman without respiratory disease or smoking history, a chronic productive cough without bronchiectasis, negative infectious investigations, severe endoscopic and histologic lesions, and above all remarkable steroid efficacy. Systematic research and early treatment of these manifestations avoids aggravating pulmonary disease, especially secondary bronchiectasis. Though less frequent, other respiratory manifestations of ulcerative colitis have been described, such as asphyxiating tracheal stenosis, pneumonia or interstitial pulmonary diseases, pleurisy or pleuro-pericarditis.

[Low-grade papillary adenocarcinoma of the endolymphatic sac. Report of three cases with immunohistochemical study].

Glandular tumors involving the mastoid and the middle ear are rare, and distinguishing between adenoma and adenocarcinoma remains difficult. Among these latter lesions, two distinct patterns are accepted. One of them, the papillary form takes a more aggressive course with wider regional spread and must be separated from the other type, the middle ear carcinoma. Its microscopic appearance and clinical course have been extensively described by Heffner who considered it as "low-grade adenocarcinoma of probable endolymphatic sac origin". A few cases have been associated with von Hippel-Lindau disease. Three cases of papillary adenocarcinoma of endolymphatic sac origin are reported. One concerned an isolated tumor, the two others were associated with von Hippel-Lindau disease. Their clinical, pathological and immunohistochemical data are presented.

Papillary neoplasm of the endolymphatic sac in a patient with von Hippel-Lindau disease.

Glandular tumours involving the middle ear and the mastoid are rare, and distinguishing between adenoma and adenocarcinoma is difficult. Two distinct histopathological patterns are accepted. While their clinical presentation differs, both require primary surgical treatment and both have a high rate of local recurrence. The papillary form takes a more aggressive course and wider regional spread. This pattern occurs predominantly in women. Its microscopic appearance and clinical course have been extensively described by Heffner who considered it as "low-grade adenocarcinoma of probable endolymphatic sac origin". A few cases have been associated with von Hippel-Lindau disease. The case of a 32 year old black woman is described. It is suggested that papillary adenocarcinoma of the endolymphatic sac should be considered in the spectrum of neoplasms seen in von Hippel-Lindau disease.

[Brain metastasis of a cutaneous neuroendocrine carcinoma. Apropos of a case].

The authors report the case of a 69-year-old woman with a brain metastasis from a cutaneous neuroendocrine carcinoma. The initial lesion was situated on the leg. No other secondary lesion was found. The cutaneous neuroendocrine carcinoma was initially considered to be a locally malignant tumor. In fact, it is frequently complicated by metastases. However, brain secondaries remain rare.

[Endonasal microsurgery of antro-choanal polyps].

Between 1986 and 1991, 33 patients were operated on by the senior author. Neither sex, nor side prevalence has been observed. In 50% of the cases, the patient was a teenager. In 18% of the cases, a cystic oedematous transformation was the cause of the polyp. Its treatment must be surgical. Five cases were operated on by gingival access, the others by median and inferior meatotomy which is recommended by the authors. They found one recurrence out of the recorded 24 cases.

[Papillary--cystic tumor of the pancreas. Apropos of 1 case with histological, immunohistochemistry and ultrastructural study].

The authors report the clinical and histological features of a case of papillary and cystic tumour of the pancreas in a 34 year old man. The solid and papillary tumour architecture associated with pseudocystic areas and a richly vascular stroma gave this tumour an original histological appearance. The study of the immunochemical and ultrastructural features of the tumour cells suggested an acinar differentiation.
