[Peutz-Jeghers syndrome. Description of a case and literature review].

The authors describe the case of a 7 year old boy who presented an intestinal intussusception due to a large jejunal hamartomatous jejunal polyp. The preoperative diagnosis of Peutz-Jeghers syndrome was based on typical mucocutaneous pigmentation and confirmed by radiological examination including computerized tomography of the abdomen. Following recent data from the literature, a long-term surveillance is justified after diagnosis of this syndrome, since malignant degeneration may occur within the intestinal polyps as well as in other organs.

Argyrophilic breast carcinoma, single metastasis to the pituitary gland.

Five years ago, a 44 year-old woman presented with an apparently localized cancer of the right breast, initially treated by surgery, adjuvant chemotherapy and radiotherapy. After a 4 year disease-free interval, she developed bi-temporal hemianopsy, due to a suprasellar tumor causing compression of the optic chiasma. The tumor was resected by the transsphenoidal route and histological examination revealed neuroendocrine characteristics described as "argyrophilic breast carcinoma".
