Polymorphous low-grade adenocarcinoma of the parotid gland.

PubMed (1998)

Roberto Puxeddu P Puxeddu G Parodo Gavino Faa

Polymorphous low-grade adenocarcinoma of the salivary glands is a well-defined clinico-pathological entity which occurs almost exclusively in the oral cavity. Only few reports have documented it in the parotid gland. The authors report an additional case of de novo polymorphous low-grade adenocarcinoma of the parotid and describe the histological and immunocytochemical features of the neoplasm. The current literature is also reviewed.

Secretory mechanisms of human ceruminous glands: A transmission and scanning electron microscopic study

The Anatomical Record (1980)

F Testa-Riva P Puxeddu

Two secretory mechanisms (eccrine and apocrine) were observed by transmission and scanning electron microscopy in the same secretory cells of the human ceruminous glands. The eccrine secretion occurs as a typical exocytosis by fusion of the limiting membrane of the secretory granule with the apical plasmalemma. The apocrine secretion is more complex and takes place by sequential steps: bulging of the cellular apex into the lumen, constriction of the projection, and detachment of it from the cell. This mechanism generally causes the removal of the entire projection all at once by decapitation at its base; some variations of this process have been found, however, and are described in the present work. A double membrane, apparently separating the apical protrusion from the rest of the cell, is noticeable in our photographs. Nevertheless, even if this membrane is very similar to a demarcation layer, we consider it as an intercellular double membrane separating two obliquely sectioned cells.

Histological and Ultrastructural Findings on Mucocele of Maxillary Sinus

ORL (1986)

E Proto Santa Cruz P Puxeddu

The authors describe a rare case of mucocele of maxillary sinus and, on the basis of the histological and namely of the ultrastructural findings, they maintain that the mucocele has in all probability a multiple pathogenesis being dependent not only on the inflammatory processes, but also on other local predisposing factors and namely the active participation of the mucosa in the formation of the cavity of mucocele.
