[Hodgkin's lymphoma with nodular sclerosis. A report of a case with an unusual sternal location at the onset]. / Linfoma di Hodgkin a sclerosi nodulare. Descrizione di un caso con insolita localizzazione sternale all'esordio.

The authors report the case of a boy, 9 years old, with a mass in the sternum and the anterior region of the mediastinum. A biopsy of the sternal mass was performed and demonstrated a Hodgkin disease variety nodular sclerosis. The disease was classified as stage III A after that two lymph nodes on the right side of the groin were revealed by lymphography. Therapy consisted of 6 alternate MOPP/ABVD cycles, followed by mantle and inverted Y field radiotherapy for a total of 25 Cg and 5 Cg booster on a sternum. During chemotherapy there was a complete regression of the disease in all sites. At present the patient is healthy and in complete remission and "off therapy", with a follow-up of 32 months. The most interesting aspect of this case is the sternum involvement as the initial manifestation of the nodular sclerosing form of Hodgkin's disease.

[A rare case of choledochocele associated with calculosis of the gallbladder]. / Un raro caso di coledococele associato a calcolosi della colecisti.

The authors report their experience of a case of choledochocele (choledochal cyst) with stones, associated with a gallstone. The exceptional observation diagnosed before the operation node it possible to program total removal of the cyst.

Pulmonary alveolar microlithiasis. A case report with a discussion of differential diagnosis.

The rare disease of pulmonary alveolar microlithiasis is characterized by innumerable microscopic stones, mainly of tribasic calcium phosphate, within the pulmonary alveoli. In a 13-year-old boy an earlier radiological examination showed diffuse lung opacity. The main differential diagnoses taken into consideration were sarcoidosis, idiopathic hemosiderosis, diffuse interstitial fibrosis and alveolar proteinosis. The correct diagnosis was made after a lung biopsy which showed intra-alveolar microliths. The radiological findings are in agreement with the reports in the literature. The specific X-ray features of pulmonary alveolar microlithiasis are calcified opacities, nodules, hilifugal trabeculations and pleural striae. These radiological signs are sufficiently diagnostic to restrict lung biopsy to particularly difficult cases. The disease is resistant to all therapeutic measures.
