Childhood thoracic actinomycosis: case report.

Actinomycosis is a rare bacterial infection. It has a pseudotumoral appearance when localized to the lungs or mediastinum. The diagnosis is often delayed because clinical presentation is nonspecific, bacteriologic diagnosis is difficult, and culture growth is slow.

[Peritoneal hydatidosis in children. Report of a historical case].

Peritoneal hydatidosis is a rare localisation of hydatic disease, most often secondary to a hydatic cyst of the liver. Its primitive form is considered due to a haematogenous diffusion through arterial vessels. We report a historical case of peritoneal hydatidosis concomitant to a hepatic localisation, in a 13-year-old girl.

[Pheochromocytoma in children. Two case reports].

Severe sustained hypertension occurs in only 0.1% of the pediatric population and only about 2% of these patients will have an underlying endocrine cause. Pheochromocytoma as a catecholamine secreting tumour causing severe hypertension is exceedingly rare in children.

[Laryngeal dyspnea caused by cervical hydatidosis: apropos of a case].

Hydatid cysts rarely present as a cervical tumor. We report a case of hydatid cyst of the neck in a child with multiple hydatid cysts in the liver, which was revealed by laryngeal dyspnea. Symptoms occurred in a six year-old country dweller, who presented with progressive laryngeal dyspnea.
