[Mixed tumour of submandibular salivary gland. Case report]

The authors present the case of 14 years male child with tumour located on submandibular salivary glands. It was proceeded the biopsy and tumour excision, the tissue fragments being further processed at paraffin, sectioned and than stained HE, PAS, Alcian-Blue, Van Gieson and Gordon-Sweet. The first biopsy performed from the latero-cervical ganglion revealed the presence of an benign tumour of salivary gland. Totally excision of the tumour emphasized the presence of a salivary gland encapsulated tumour, sized 2.5/2.5/2 cm, nodule shaped, white colored, hard consistency. Histopathologic examination revealed the existence of a proliferating encapsulated tumor, well separated from the normal adjacent tissue. The small sized tumour cells with moderate cytoplasm induce formation of glandular lumens, some of them with cystic dilatation, with mucous content. Other tumour cells form small cords or nests. The tumour stroma forms mucoid areas, some with osteoid appearance. We have presented a case of a 14 years aged child with pleomorphic adenoma with rare location within the submandibular salivary gland. The post biopsy rapid increase of the tumour imposed the totally surgical gland excision.
