Neural fibrolipoma or fibrolipomatous hamartoma is an uncommon benign tumor that usually arises in the median nerve. Fibrofatty tissue proliferates around the nerve and infiltrates the epineurium and perineurium. We report a case of fibrolipomatous hamartoma of the left median nerve in an 18-year-old woman. Our objective was to describe the pathognomonic magnetic resonance imaging features, whose presence obviates the need for a diagnostic biopsy.
Solitary fibrous tumour (SFT), a rare mesenchymal neoplasm usually arising from the pleura, may also occur in many other extra pleural sites. It has exceptionally been described in the pancreas. This report describes the case of a benign SFT of the pancreas occurring in a 41-year-old man who presented with a solid epigastric mass. Pathological and immunohistochemical findings are presented. Imaging features on ultrasonography, CT, MRI, and arteriography are widely detailed. Surgical resection of the tumour was performed, and the patient died from postoperative complications.
A case of colonic perforation complicating percutaneous nephrolithotomy in a 64-year-old woman is reported. Nonoperative management was successful with the creation of a controlled colocutaneous fistula by pulling the nephrostomy tube back from the kidney to the colon and the use of an elemental diet and antibiotics. Internal urinary drainage was not necessary.
Cystic phaeochromocytoma is a rare occurrence. We report a case of a 42-year-old woman who presented with the cardinal symptoms of phaeochromocytoma with elevated serum catecholamine levels. Radiological investigations showed a cystic mass in the right adrenal. Right adrenalectomy through a subcosal incision was performed and pathological examination concluded to a cystic phaeochromocytoma. We discuss the pathophysiology of such cyst formation as well as differential diagnoses.
AIM: To evaluate the epidemiological clinical features and herapeutic results of gastrointestinal stromal tumour (GIST). PATIENTS AND METHOD: This retrospective study concerned 25 cases of gastrointestinal stromal tumour from January 1993 to December 2002. All patients have been operated and the diagnosis of GIST has been confirmed by histological and immunohistochemical study of pieces of resection or biopsies. RESULTS: Population include II men and 13 women with a mean age of 64 years. Symptomatology was dominated by abdominal pain (54% of cases) and the digestive haemorrhage (46% of cases). A palpable mass has been found in 29% of cases. The tumour was gastric in 17 cases, small intestinal in 6 cases, colic in 1 case and rectal in 1 case. A double gastric localization and small intestinal was found in 1 case. The mean tumour size was 8 cm (1 to 30 cm). A tumour resection has been achieved in 23 cases (96%), extended to neighbourhood organs in 2 cases. The morbidity was 12.5% and there was no operative mortality. Histologically, tumour was of low grade in 10 cases, high grade in 10 cases and unclassified in 5 cases. With a median follow up of 27 months (2 to 108), we observed 4 cases of loco-regional recurrence. Overall survival at 2 years was 74% for the whole population and 35% for the high grade. Independent prognostic factors recovered were the degree of malignancy (p = 0.01) and the local recurrence (p = 0.01). CONCLUSION: The treatment of the GIST is surgical. lymphadenectomy is superfluous. The new oral chemotherapies that inhibits Tyrosine Kinase seems to be promising.
We report a case of a supernumerary kidney discovered while investigating an isolated pyuria in a 47-year-old male patient. Embryology and diagnostic difficulties are discussed.
