[Polymorphous low-grade adenocarcinoma of the accessory salivary glands--a case report]. / Adénocarcinome polymorphe de faible malignité des glandes salivaires accessoires--une observation.

A case of polymorphous low-grade adenocarcinoma of minor salivary gland is reported. This tumor was first described in two clinical case series in 1983. Before that time most of these neoplasms were diagnosed as benign salivary gland neoplasms (pleomorphic adenomas) or salivary malignant conditions (malignant pleomorphic adenomas, adenoid cystic carcinomas, papillary adenocarcinomas and adenocarcinoma not otherwise stated). This neoplasm, with few exceptions, originates in minor salivary gland tissues of the palates or buccal mucosa. It is characteristically slow to enlarge. Clinical reports show the neoplasm present for many years before diagnosis. The tumor have a variety of morphological patterns, a cytological uniformity and an infiltration into adjacent structures. The treatment is a wide local excision. Recurrences and lymph node metastases are rare.

[Angiolymphoid hyperplasia with eosinophilia]. / Hyperplasie angiolymphoïde avec éosinophilie.

INTRODUCTION: Angiolymphoid hyperplasia with eosinophilia (HALE) is a rare, benign proliferative vascular disorder of unknown etiology which typically presents as tumor-like nodules of the skin or subcutaneous tissue. It concerns mostly young female adults. We report a case of HALE located on the ear auricle diagnosed by biopsy. The outcome was total regression. OBSERVATION: An 81-year-old male patient presented with a lesion of the whole ear auricle. A diagnosis of HALE was confirmed histologically on biopsy. The evolution was marked by spontaneous and complete regression in 2 months. There was no recurrence after 1 year of follow-up. DISCUSSION: The etiology of this disease remains hypothetical. It poses real diagnostic problems with other types of proliferation, but its main differential diagnosis is Kimura disease. Its treatment has not been codified yet. Spontaneous regression is possible and justifies following the patient from 3 to 6 months, before a possible surgery.
