[SEAP-IAP recommendations for the collection, storage and use of biological materials of human origin and related data intended for research. Generic biobank consideration and ethical-legal review (Part II)].

The working group set up by the SEAP-IAP addresses in this Part II some general considerations and five particular considerations to be taken into account when a biological sample of human origin, coming from our archives, acquires a different destination from the usual one, in this case for research. From this moment on, we must follow mandatory legal and ethical rules, and the different recitals provide us with guidelines to ensure good practice, both for biological material and its associated data. The traditional task of custody given to the Pathological Anatomy is approached, as always, from the point of view of responsibility and, in this article, adjusted to its time.

Expression of so-called adhesion proteins and DNA cytometric analysis in malignant parotid tumours as predictors of clinical outcome.

Tumours of the salivary glands are rare, and account for only 0.5-1% of all tumours. We have analysed the cytoarchitectural structure of such tumours by studying 3 binding proteins that act on different parts of the glandular epithelial architecture: e-cadherin, laminin, and CD44.

[Lipoma arborescens of the bicipital bursa].

Lipoma arborescens is a rare benign entity characterized by proliferation of villous fat tissue in subsynovial layer that usually affects the knee joint. We report a case of lipoma arborescens in bicipitoradial bursa of the elbow in a 44 year-old female patient. In spite of this rare location, radiographic findings by ultrasonography and magnetic resonance imaging made diagnosis possible.

Fibroblast growth factor receptor 3 mutations in epidermal nevi and associated low grade bladder tumors.

Epidermal nevi (EN) are benign lesions presenting at birth or in childhood. Based on the occurrence of fibroblast growth factor receptor 3 (FGFR3) mutations in seborrheic keratosis and urothelial carcinomas (UC), and the identification of two young patients with EN and UC, we hypothesized that mutations might occur in EN. The R248C mutation was found in 6/23 (26.
