Cutaneous metastases presenting as the first sign of cancer are rare. We present two cases of such metastases, one being a so-called sister Mary Joseph's nodule. The histologic findings revealed adenocarcinomas with features suggesting a primary gastrointestinal neoplasm.
Phlegmonous gastritis is a rare bacterial infection of the stomach. Its diagnosis is difficult and has a poor prognosis. The authors report a case of phlegmonous gastritis occurring in a 50 year-old woman in whom the diagnosis was made by microscopic examination after surgery for intestinal occlusion. The patient died a few hours after the operation.
A 54 year old male developed plant thorn synovitis of the knee followed five months later by nonerosive seronegative polyarthritis. The occurrence of chronic inflammatory joint disease shortly after plant thorn synovitis is exceedingly rare. The relationship between the two events remains to be clarified.

We report one case of vaginal leiomyoma revealed by dysuria operated with success. Our observation are discussed with the review of the literature data.
Primary malignant fibrous histiocytoma of the pancreas are rare. To our knowledge only 3 cases have been found in the literature. We report a new case of primary malignant fibrous histiocytoma of the pancreas in a 72 years old man. Various patterns were intermixed in this tumor: storiform, giant-cellular and myxoid patterns. After surgical resection, within one year, there were recurrence of the tumor and metastasis to the liver resulting in the death of the patient.

The authors report two cases of congenital ureteral valves of the upper third of the ureter complicated by renal stone in two children and diagnosed by I.V.P. The two patients underwent a resection of the pathological segment and a pelvic-ureteral anastomosis successfully. The review of the literature data regarding ureteral valves allowed to emphasize the uncommon of the bilateral form complicated by renal stone and the better preoperative diagnosis by ureteroscopy and antegrade pyelogram.
The authors report a case of malignant giant cell soft tissue tumor which appeared as a skin tumor of the thigh in a Tunisian women aged 17 years. Immunohistochemical study showed that the giant cells recognized KP1 antibody, while spindle interstitial cells reacted with anti-factor XIIIa antibody. The patient is alive and well eighteen months after large surgical removal. Two similar cases have been reported in the literature. Differential diagnosis, histogenesis and prognosis of this rare tumor are discussed.

The authors report a case of carcinosarcoma which occurred in the uterus of a 69 year old woman. The survey of literature shows that it is a scarce tumor (1-3% of the uterine cancers). Its definition and its classification are still debated. Its final diagnosis is anatomopathological. Its treatment is generally radio-chirurgical and its prognosis is bad.
Twenty burned patients divided in three groups according to the severity of the lesions were investigated at 1- or 2-day intervals for up to 5 weeks after injury. Plasma elastase levels were elevated during the first day after injury and were correlated with the area of the burns. However, plasma elastase was rapidly bound and inactivated by protease inhibitors. Leucocyte counts, fever and the concentration of alpha-1-proteinase inhibitor were not correlated with the extent of the burn. The rise of plasma elastase was not accompanied by consumption of the elastase inhibitory capacity (EIC) of plasma, which increased to a plateau around day 5. The EIC values were in accord with the rise of alpha-1-proteinase inhibitor, the major anti-elastase agent in plasma. Studies of blister fluid in eight patients showed that the elastase content was higher than that of corresponding plasma, while the concentration of alpha 1-proteinase inhibitor and the EIC were comparable with those of plasma. Measurements of the levels of tumour necrosis factor released by stimulated macrophages in five patients with major burns showed no significant increase compared with controls.

Adult nephroblastoma is a rare tumor. The authors report a new case observed in a 35 year old woman in whom the diagnosis was made by histopathology. The authors study the particular features of this tumor. Its prognosis appeared to be poorer than that of renal adenocarcinoma.
A case of spontaneous subcapsular hematoma of the kidney is reported. CT scan findings and etiologies are examined in the light of previously published data. An etiology-specific therapeutic strategy for subcapsular hematoma of the kidney is proposed.
The authors report a case of infantile embryonal carcinoma of the submandibular gland in a nine months old infant. The diagnosis was based on typical histopathological features, and positive reaction of tumor cells with alpha-foetoprotein. The patient was treated by wide surgical excision and chemotherapy. The clinical course was favourable two years later with normalization of serum alpha-foetoprotein levels and with no abnormality on the thoraco-abdomino-facial CT scan.
