Cystic hygromas (CHs) are benign congenital malformations of the lymphatic system mainly diagnosed in small children aged less than two years old. They may give a multitude of local, sometimes severe complications. The most used method of treatment is surgical removal. In this paper, we present the case of a CH of a 13-year-old boy, localized in the right lateral region of the neck, diagnosed through magnetic resonance imaging (MRI), with excellent results of the surgical treatment.

Delayed hypersensitivity reactions are inflammatory reactions initiated by mononuclear leukocytes. These reactions are mediated by T cells and monocytes/macrophages rather than by antibodies. We describe a case of 50 years old man with lung type IV hypersensitivity. The case of lung delayed hypersensitivity presented has some particular histopathological and immunohistochemical features. The diagnosis of lung delayed type hypersensitivity requires analysis of correlation between clinic, radiographic, physiologic and pathologic criteria.
