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

“…On stretching the overlying skin, the mass showed several facets and irregular angles sues representing all forms of ectodermal differentiation. The second case, described by Ito et al [4] in 1982, was a 50-year-old female with a tumor of 5-year duration arising in the lower helix. The tumor measured 2.5×2.0×1.7 cm, which was the largest among the reported cases.…”

“…The authors postulated that the tumor was derived from the sweat glands or sebaceous glands of the auricle and could be classified as a chondroid syringoma. [4] A case was reported by Yim et al [5] involving a 40-year-old woman with a 3-year history of a 0.5-cm-sized mass on the superior helical rim. The neoplasm was proposed to originate from the apocrine glands due to a positive stain for gross cystic disease fluid protein.…”

“…Of the four cases, two were reported as a mixed tumor of skin [3,5] while the other two were pleomorphic adenomas [4,6] . In 1945, Morehead reported the first case of a 53-yearold female who had a 1-cm-sized tumor with a duration longer than 10 years located on the superior surface of the auricle [3] .…”

“…A chondroid syringoma arising in the helix is extremely rare, and only four cases have been reported in the literature [3][4][5][6] . A case of chondroid syringoma clinically mimicking pilomatricoma with a rare location on the superior helical rim of the left ear is reported, along with a review of the literature.…”

Chondroid syringoma is a rare benign, skin appendageal tumor, also known as mixed tumors of the skin. The clinical presentation of chondroid syringoma is non-specific, and the diagnosis is made histopathologically. A case of a 74-year-old man presented with an asymptomatic 1.3-cmsized, firm, skin-colored, subcutaneous nodule of 8 years' duration on the superior helical rim of the left ear. Stretching of the skin over the tumor showed the "tent sign" with many facets and angles, a pathognomonic sign for pilomatricoma. The nodule was totally excised under the impression of pilomatricoma. The histopathologic findings showed the characteristic features of chondroid syringoma. Chondroid syringoma arising in the helix is extremely rare; only four cases have been reported in the literature. This case represented the fifth documented case of chondroid syringoma occurring in the helix with clinical presentation mimicking pilomatricoma and the first case involving a male patient. A review of the relevant literature is also presented.
