11/344. Benign pleomorphic adenoma arising from the palpebral lobe of the lacrimal gland associated with elevated intraocular pressure.

    A 46-year-old man complained of a painless mass in the left upper eyelid. At age 51 years, the patient complained of dull pain in the left eye and diplopia. His left intraocular pressure had increased to 33 mm Hg. No proptosis was noted. The nontender mass in the eyelid was palpable. Computed tomography showed a mass anterior to the orbital rim compressing the globe. The lesion was removed en bloc by a transconjunctival approach. Histopathologic examination of the excised mass showed myxomatous stroma and highly cellular epithelial areas. Postoperatively, the left intraocular pressure normalized. To our knowledge, benign pleomorphic adenomas arising from the palpebral lobe of the lacrimal gland associated with elevated intraocular pressure, as demonstrated in our patient, may be rare.

12/344. A new observation of the Carney's triad with long follow-Up period and additional tumors.

    The etiology of the Carney's triad (gastrointestinal stromal tumors, pulmonary chondromas, and paragangliomas) is unknown, and only 57 cases have been reported since its identification in 1977. We report the clinical course of a female with the complete triad and some additional tumors. Bilateral vagal paragangliomas were treated surgically and with radiotherapy between the ages of 24 and 26 years. Subsequently she underwent surgery for a gastric leiomyosarcoma (27 years), a pleomorphic adenoma of the parotid gland (49 years) and a multifocal breast cancer with axillary spread (50 years). A calcified lesion was also noticed in the left lung, the radiologic diagnosis of which was consistent with chondroma. A mediastinal paraganglioma, detected at 56 years on a control X-ray of the chest, was partially excised at 63 years. At the last control, performed at 66 years, the patient was alive with residual cervical and mediastinal paraganglioma. Her younger brother was affected by Hirschsprung's disease and died at 54 years of rectal cancer. Her daughter is 33 and has been suffering since birth with severe constipation. In conclusion, this is one of the longest followed-up patients with Carney's triad. Her case illustrates the need for early recognition of the setting in order to detect the component tumors at a stage when surgery may be curative, and careful and life-long follow-up, both because the multicentricity of the classic components tends to manifest metachronously and because of the tendency to develop other tumors, some of which may be malignant. Furthermore, the presence of Hirschsprung's disease in the patient's family, coupled with the alleged common origin of two component lesions from derivatives of the neural crest, open new avenues for the understanding of this disorder.

13/344. Pleomorphic adenoma of the nasal septum.

    Pleomorphic adenoma is the commonest benign tumour of the major salivary glands. It can also occur in minor salivary glands, mainly in the oral cavity, but also in other sites in the head and neck both within and outwith the upper aerodigestive tract. We present a rare case of pleomorphic adenoma of the nasal septum with consideration of the clinical management and a review of the literature.

14/344. An unusually large, solid tumor of the parotid gland.

    Of the parotid gland tumors, benign pleomorphic adenomas are the most commonly encountered. Although occurring relatively frequently in the general population, it is rare for the surgical community to encounter one that weighs more than a few ounces. The authors report a woman who avoided early surgical intervention and eventually presented with an extraordinarily large parotid gland tumor. This is the largest solid (without cystic change), benign pleomorphic adenoma of the parotid gland in the English medical literature, weighing 8.03 kg.

15/344. Familial mixed tumors of the parotid gland.

    BACKGROUND: The most common neoplasm of the parotid gland is the pleomorphic adenoma. The familial occurrence of such tumors arising within the parotid gland is rare, with only 3 previous reports in the literature. Bilateral synchronous pleomorphic adenomas of the parotid gland are also uncommon. We report 2 siblings with pleomorphic adenomas of the parotid gland, 1 of whom had bilateral synchronous mixed tumors. patients and methods Chromosomal analysis of tumor cells from the sibling with bilateral adenomas revealed the translocation t(3;12)(p21;q15). Chromosome 12q breakpoints have previously been identified in a wide variety of solid tumors including pleomorphic adenomas of the parotid gland. CONCLUSIONS: We discuss bilateral mixed tumors, familial parotid tumors, and the potential for a genetic predisposition for the recurrence of such parotid tumors, as suggested by characteristic chromosomal translocations associated with mixed tumors.

16/344. A minor salivary gland tumour presenting with dysphagia.

    A case is reviewed of a giant benign myoepithelioma of the soft palate presenting in an elderly female patient. Due to the large size of the lesion and its mass effect the patient developed dysphagia with subsequent significant weight loss. The clinico-pathological features of this rare tumour are described and the literature reviewed.

17/344. Pleomorphic adenoma (benign "mixed" tumor) of the human female breast. Case report.

    A case of solitary pleomorphic adenoma, ("mixed" tumor of salivary gland type) of the left breast associated with the right breast fibroadenoma in 43-year-old woman is reported. The paper describes clinical, cytological, immunohistological and pathological findings in this case and indicates the importance of separating this benign entity from malignances with stromal metaplasia.

18/344. Benign chondroid syringoma: report of a case clinically mimicking a malignant neoplasm.

    Chondroid syringoma, or mixed tumor of skin, is an uncommon sweat gland tumor most often seen in the head-and-neck region of patients in the sixth or seventh decade. Tumors usually present as asymptomatic, slowly growing masses. Histologically, there are both epithelial and stromal components. The treatment of choice is local excision. Rare malignant examples have been reported, commonly involving the extremities. We present a case of cutaneous chondroid syringoma arising in the thigh of a 28-year-old female. The tumor grew over a 4-year period, increasing rapidly in size over the last few months with fixation and pigmentation of the overlying skin clinically mimicking a malignant neoplasm. Such cutaneous appendage tumors are uncommon, and surgeons may be unfamiliar with them.

20/344. Recurrent malignant chondroid syringoma of the foot: a case report and review of the literature.

    Malignant chondroid syringoma, or mixed tumor of the skin, salivary gland type, is an uncommon neoplasm believed to originate in sweat glands. This neoplasm occurs mostly in women and is typically seen in the extremities and torso. A case of recurrent malignant chondroid syringoma of the right foot in a man aged 34 years is described with a review of pertinent literature. The surgically excised neoplasm was evaluated by routine histology, immunohistochemistry, and transmission electron microscopy. The malignant chondroid syringoma showed microscopic dermal satellite tumor nodules. Immunohistochemical staining was positive for keratin and S100 and negative for actin and p53. Ki-67 showed <10% positive staining. Ultrastructurally, the neoplasm was composed of epithelial cells with tonofilaments, cell junctions, and electron-dense amorphous keratin-like substance in the intercellular spaces. No evidence of myoepithelial differentiation was noted. Given the tumoral size, acral location, and histologic findings, the neoplasm was classified as a malignant chondroid syringoma. After reviewing the literature, it became apparent that wide surgical excision, adjuvant radiation therapy as well as patient education are critical in facilitating long-term survival.
