Pleomorphic adenoma of the auricle

Abstract

Sirs: Pleomorphic adenoma (PA) frequently arises from the salivary gland, but it may also rarely arise from sebaceous glands in the skin. Only a few cases of PA in the auricle have been reported [5,6,9]. In this paper we report a case of PA in the auricle that was successfully resected.A 50-year-old Japanese housewife noticed a grain-sized growth in her right ear, but she left this untreated for 5 years. During this period, the lump grew slowly but was otherwise asymptomatic. When the tumor became as large as a walnut, she came to our clinic for its cosmetic removal. On examination a firm mass was seen in the right auricle. The size was approximately 30 × 20 × 18 mm (Fig. 1). Lymph nodes of the neck were not palpable. Aspiration cytology showed no evidence of malignancy but was suggestive of a PA.Surgical resection of the ear tumor was performed on 22 August 1997. An elliptical skin incision was used that included a 5-mm margin around the base of the tumor. Frozen section histology showed no invasion of the tumor into the cartilage of the auricle. After resection of the tumor and skin with perichondrium, the resultant skin defect was covered with a postauricular skin graft (Fig. 2). Healing was unremarkable and a cosmetically acceptable outcome was obtained.Grossly, tumor was seen to be a grayish-white multilobulated mass. Microscopically, tumor cells were found to be arranged in

Pleomorphic adenoma of the pterygopalatine fossa: a case report

“…Several cases of schwannoma have been reported arising from this area [11,8]. PA of the upper respiratory tract or skin may originate from either sebaceous or ectopic salivary glands [5]. PA in the upper respiratory tract may also represent a metastasis from a salivary gland tumor, although metastasis of PA to the pterygopalatine fossa has never been reported [9].…”

Auricular pleomorphic adenoma: A rare presentation

“…If the tumor is large or arising in the helix wedge resection of auricle, skin, perichondrium, and cartilage may be required. [11] On microscopic examination, salivary gland tissue was present in the background of chondromyxoid area with epithelial and myoepithelial cells. This suggests that pleomorphic adenoma of auricle in this case was arising from ectopic salivary tissue not from sweat or sebaceous glands.…”

“…However, histopathological features of pleomorphic adenoma arising from sebaceous glands and salivary glands are same. [11] conclusIon Pleomorphic adenoma is a rare tumor of auricle. It usually present as slow-growing painless mass with cosmetic deformity.…”

Auricular pleomorphic adenoma: Case report and review of literature

“…However, histologically PAs arising from the sebaceous gland and from the salivary gland are the same. [5] Generally, PAs in the auricle present as small, nontender subcutaneous masses, which are either slowly progressive or static in size. On the auricle, they are generally asymptomatic, and the patient seeks consultation for cosmetic purposes only, as in our case.…”
