Inflamed adenolymphoma with cholesterol granuloma

Abstract

Twelve cases of adenolymphoma with inflammation are described. Pre-operatively, three of these patients presented clinical signs of inflammation in the parotid gland. In ten cases purulent exudate could be aspirated from the tumour. Rupture of the cyst may cause an aseptic inflammation in the surrounding tissue. It is concluded that adult patients with clinical or cytological signs of inflammation in the parotid gland must be supervised until the gland is normal in order not to miss an underlying tumour.

Fine Needle Aspiration Cytology and Diagnostic Pitfalls in Warthin’s Tumor with Necrotizing Granulomatous Inflammation and Facial Nerve Paralysis

“…The oncocytic quality of the WT epithelium remains unexplained, but may represent a metaplastic response to tobacco smoke. 4,22,28 Diagnostic cytologic preparations of WT show various-sized sheets of oncocytes and variable numbers of benign lymphocytes on a granular, proteinaceous background. However, determining a definitive diagnosis can be difficult to impossible when the tumor is complicated by degenerative, reactive, inflammatory or metaplastic changes.…”

Mycobacterium tuberculosis infection within Warthin’s tumor: Report of two cases

“…The presence of necrosis or inflammatory changes in Warthin’s tumor is well documented. Among 59 cases of the tumor covered in one series, 12 presented signs of inflammation, with polymorphonuclear leukocytes, macrophages and necrotic debris 5 . Eveson and Cawson reviewed a total of 323 Warthin’s tumors, and found 20 cases (6.2%) with extensive necrosis, fibrosis and inflammation 6 .…”

Inflamed benign tumors of the parotid gland: Diagnostic pitfalls from a potentially misleading entity

“…The main problem in the review of the literature on inflamed benign tumors is caused by the different definitions and names used by different authors for this disease: to the clinical otolaryngologist, an “infected” benign tumor of the parotid gland (a confirmed cystadenolymphoma in all cases described previously) represents a condition with easily recognizable symptoms. Diagnostic suspicion is strengthened by ultrasound findings and confirmed by histopathologic examination . From the clinical point of view, the term “inflamed” is preferred instead of “infected,” as signs of inflammation seem to dominate the clinical picture in the parotid gland.…”
