Спасибо за краткий курс по новообразованиям слюнных желёз! В данном случае морфологи написали: миксома (плеоморфная аденома). Хотя для такого возраста более характерны Warthin Tumor, но для них характерно наличие кистозного компонента.

Pleomorphic adenomas (benign mixed tumors) are the most common tumors of the salivary gland and are most often located in the tail of the parotid gland. When found in the minor salivary glands, the hard palate is the site most frequently involved, followed by the upper lip.

These tumors were termed pleomorphic because of the epithelial and connective tissue components that compose them in varying degrees. Their gross appearance is a round, smooth mass with a thin, delicate, incomplete capsule. Of note, pleomorphic adenomas that arise in the minor salivary glands usually lack a capsule. These tumors grow slowly, although they may become larger than other SGTs. The thin, delicate capsule may have projections into the surrounding parotid tissue. This is of particular clinical significance because obtaining clean margins and avoiding spillage are mandatory to minimize recurrence.

Microscopically, benign mixed tumors are characterized by variable, diverse, structural histologic patterns. Frequently, they have growth patterns of sheets, strands, or islands of spindle and stellate cells, with a myxoid configuration occasionally predominating. Treatment of benign neoplasms involves the complete surgical excision of the affected gland. If the parotid gland is involved, superficial parotidectomy with standard facial nerve dissection and preservation is the procedure of choice. Enucleation is contraindicated because of the tendency towards tumor spillage that can lead to tumor recurrence.

Да, пожалуйста! Рад был помочь

А если серьезно, то большое спасибо за поучительный случай. В смысле и информативном и организационном - пример того как нужно "делать диагноз" за часы или даже минуты.
