ABSTRACT
Cases of two 48 and 55 year-old males affected of facial granuloma with eosinophilia are presented. In both cases direct immunofluorescence studies revealed the presence of IgG, IgA and C3 along the basement membrane. A brief comments on clinical and histological appearance, previous immunofluorescence studies, pathogenesis and treatment are made.

Malignant change in some keratinous cysts is a possible but rare condition. It seems acceptable that many publications concerning squamous cell carcinomas arising from previous cysts, actually correspond to the entity which Wilson-Jones called "proliferating epidermoid cyst" and they must be considered as pseudomalignant lesions, despite the presence of some features that may lead to a diagnosis of carcinoma. Although it is rare, which is nowadays called "proliferating Trichilemmal cyst", should be widely acknowledged since its misdiagnosis as squamous cell carcinoma leads to surgical treatment which is more drastic than necessary. Herein is presented an unusually situated case of proliferating Trichilemmal cyst and a review of the principal characteristics that have been pointed out in this tumor.

Juvenile fibromatosis has been largely studied by several authors. Most of them have pointed out the existence of some disorders which are difficult to classify and possess peculiar features. The authors report the case of a girl who presented several tumoral lesions located on the soles and toes from birth. The clinical aspect and the histological study didn't allow us to include this patient in any determinates group. She also presented some associated skeletal alterations.
