The authors report three cases of malignant pheochromocytomas. Metastases occurred in the liver in two cases whereas malignancy was suspected in the third case because of recurrence and local invasion. One case was pregnant at diagnosis of pheochromocytoma. Pheochromocytoma was associated to papillary thyroïd carcinoma in another case. The treatment considered was surgery in all cases.
Acquired central diabetes insipidus (CDI) is a rare disease due to anatomic lesions of the hypothalamo-pituitary system. We discuss the etiologic and therapeutic aspects of CDI. Through 5 cases and a review of the literature. We report: Two cases of Langerhans histiocytosis, a 21 year old man and a 37 year old women. The CDI was the only endocrine manifestation in the man, but it was associated with panhypopituitarism and infiltration of the thyroid gland by histiocytosis cells in the women. One case of suprasellar germinoma, a 18 year old adolescent had hypocorticism, hypothyroidism, and hypogonadism associated with CDI and hyperprolactinemia. One case of pituitary cystic lesion with extension to the suprasellar area, a 36 year old women presenting with hypocorticism, growth hormone deficiency, and hyperprolactinemia. One case of neuro-Behçet's disease in a 47 year old man. He presented with strokes and CDI. When the CDI is isolated Langerhans Histiocytosis should be considered first. The exploration of the hypothalamo-pituitary region using MRI showed different anatomic lesions in patients with CDI. It is very difficult to determine definitive diagnosis before surgery in the cases of cystic lesions.
We report a case of a 22 years old type 1 diabetic man with a history of weight loss, weakness, anorexia, fever and recurrent urinary tract infection since February 2001. In April 2001, he presented anuria due to obstructive acute renal failure. Hepatosplenomegaly and lymphadenopathy were absent at physical examination. Laboratory tests revealed a high level of gamma globulin (53.4 g/l) and anaemia (haemoglobin 7.7 g/100 ml) without leukopenia and thrombocytopenia. CT scan showed multiple retroperitoneal lymphadenopathies causing compression of the two ureters, hydro-ureter associated with hydronephrosis, hepatosplenomegaly and multiple pulmonary nodes. Lymphadenopathies, anaemia, high level of gamma globulin, high titres of anti-leishmanial antibodies and the excellent outcome after treatment with meglumine antimoniate (Glucantime) confirmed visceral leishmaniasis. This report documented an unusual clinical presentation of Visceral leishmaniasis in a diabetic patient.
Vasculitis with central diabetes insipidus is a rare condition which must be recognized for an appropriate management. We report a case of Behçet disease with central diabetes insipidus. A forty seven year old men presented recurring oral and genital ulcers, skin lesions, polyarthralgia. Two years later, he showed right uveitis and central diabetes insipidus without dysfunction of the pituitary gland. Computed tomographic scan showed normal neurohypophysis and pituitary gland. Later on, he presented hemiplegia. The cerebral computed tomographic scan showed hypodense lesions. Central diabetes insipidus should not be systematically searched because it is a rare feature of the Behçet disease.
Diabetic fibrous mastoplasty or diabetic fibrous breast disease is a benign condition rarely observed. First described in 1984, it can lead to misdiagnosis because it simulates breast cancer. Diabetic fibrous mastoplasty usually occurs in patients with autoimmune disorders, particularly in patients with longstanding and complicated insulin-dependent diabetes mellitus. We present a case of fibrous mastoplasty in a patient with insulin-dependent diabetes mellitus known for 17 years. The clinical and radiological features and the clinical course are illustrative. We discuss the different pathogenic theories put forward.
