[The sphenoid: tumoral pathology].

The interest and difficulty of sphenoid tumor imaging relate mainly to its great diversity. Detection may be difficult due to variable tumor size and often misleading clinical data. Because the sphenoid is located at the center of the skull base, tumor extension may be quite variable and difficult to assess, requiring sufficient knowledge of anatomy and imaging features to detect tumor spread, especially retrograde perineural spread, since this has a negative impact on prognosis.

A new type of connective tissue nevus: isolated exophytic elastoma.

An unusual case of isolated exophytic elastic tissue nevi in the scrotal region of a 64-year-old man is described. The histological and ultrastructural findings were those of abundant abnormal elastic fibers and increased reticulin in the dermis. This hamartomatous lesion possesses clinical and histological features previously undescribed in connective tissue nevi.
