ABSTRACT
In a 45-year-old man with a hypernephroma tumor of the right kidney, a metastasis in the pituitary gland of this neoplasm was diagnosed 9 years after removal of this kidney. He complained of bitemporal hemianopsia and slight impairment of vision. A hypernephroma metastasis in the pituitary gland is very rare and few have been reported to date. In general, these metastases occur in cases with multiple metastasis to many organs, which suggests that the appearance of pituitary metastasis represents extensive disease. Many of these patients present diabetes insipidus. Visual defects are frequently associated. The Goldmann perimeter is important to detect visual field anomalies. MRI is the key radiological exam to localize the tumor. Surgery is the preferred treatment and should be undertaken quickly if visual function is affected. The histological exam should be made to confirm the diagnosis.

Complex choristomas are very rare ocular tumors. We report a case of a 3-month-old infant who was referred to us because of a left congenital conjunctivo-corneal protruding mass. Total excision removing 2/3 of the limbus was performed and replaced simultaneously by a limbal autograft. Histopathological examination of the excised choristoma revealed many pilosebaceous follicules in the conjunctival tissue, keratinized epithelium, lacrimal glands, and differentiated cartilage.

A 6-year-old boy with aphagia presented with a radiolucent foreign body, esophageal perforation, mediastinitis, and a C6-C7 spondylodiscitis. A rigid plastic gear wheel was removed via thoracotomy, and the mediastinal abscess was drained through the esophagomediastinal fistula. Treatment included antibiotics as well as nonsurgical orthopedic management of the spondylodiscitis. The recovery period was uneventful, and the patient has remained asymptomatic for 2 years. Physicians must be aware of radiolucent foreign bodies. Computed tomography is very helpful in establishing the diagnosis of radiolucent foreign body, mediastinal abscess, and spondylodiscitis.

Portal hypertension was observed in a 17-year-old girl with urticaria pigmentosa since 2 months of age. Liver biopsies showed portal and sinusoidal infiltration with mast cells although spleen biopsies showed only fibrosis. CONCLUSION. Portal hypertension is a complication of systemic mastocytosis that can lead to death. Treatment with interferon alpha might be effective.
