1/118. Middle ear adenocarcinoma with intracranial extension. Case report.

    Middle ear adenocarcinoma is a very rare, locally invasive neoplasm assumed to arise from the middle ear mucosa. Although endolymphatic sac tumor (aggressive papillary middle ear tumor) and jugulotympanic paraganglioma may show brain invasion, intracranial extension of histologically confirmed middle ear adenocarcinoma has not been previously reported. The authors describe a 53-year-old man who suffered from otalgia and tinnitus for more than 10 years and from neurological deficits for 1 year due to a large temporal bone tumor that invaded the temporal lobe. A combined neurosurgical and otolaryngological resection was performed. Pathological analysis revealed a low-grade adenocarcinoma of a mixed epithelial-neuroendocrine phenotype, which showed a close histological similarity to, and topographical relationship with, middle ear epithelium. The authors conclude that middle ear adenocarcinoma belongs to the spectrum of extracranial tumors that have possible local extension to the brain.

2/118. Helical advancement with a posterior auricular pull-through flap: A technique for reconstruction of combined helical and scaphal defects.

    ear reconstruction after skin cancer resection has traditionally challenged the reconstructive surgeon and many techniques of reconstruction have been published as a testament to this. With the widespread use of Moh's technique for resection, more tissues are now available after resection, and this has created a new challenge for the reconstructive surgeon-to use creatively all the remaining tissues and maximize the aesthetics of the ear reconstruction. This paper demonstrates a one-stage technique for reconstruction of a combined helical and scaphal Moh's defect which utilizes helical advancement with a posterior auricular skin flap.

3/118. Primary pleomorphic adenoma of the external auditory canal diagnosed by fine needle aspiration cytology. A case report.

    BACKGROUND: Pleomorphic adenoma (PA) arising in the external auditory canal (EAC) is a very rare neoplasm, thought to be derived from ceruminous glands. CASE: A 43-year-old male presented with a slowly growing mass in the right EAC. Clinical and radiologic examinations showed a well-circumscribed tumor limited to the EAC, without a connection to the parotid gland. Fine needle aspiration cytology (FNAC) revealed the typical cytologic findings of PA. The diagnosis was confirmed by histologic examination. CONCLUSION: This case illustrates that together with clinical and radiologic findings, primary PA of the EAC can confidently be diagnosed by FNAC.

4/118. Solitary adult myofibroma of the pinna.

    Solitary myofibroma is a recently described benign neoplasm of the skin or superficial soft tissue and it represents the adult counterpart of infantile myofibromatosis. This new clinicopathological entity is being recognized increasingly. A case of solitary myofibroma occurring in the pinna of a 50-year-old woman is presented. Such a lesion occurring in the pinna of an adult has not been reported in the literature.

5/118. Primary extraosseous cemento-ossifying fibroma of the auricle.

    BACKGROUND: A mass of the auricle is uncommon. An enlarging lesion may be the result of a reactive process, or a benign or malignant neoplasm. The literature is reviewed, and a case of extraosseous cemento-ossifying fibroma of the auricle is presented. methods: A 22-year-old white man presented with a 3-month history of an enlarging 2 cm mass in the right concha cavum. An incisional biopsy demonstrated cemento-ossifying fibroma. The lesion was resected en bloc, and the patient did well. There is no evidence of recurrence. RESULTS: Pathological examination of the excised mass revealed a well-circumscribed but unencapsulated spindle cell lesion with foci of osteoid and cementum deposition. It did not involve the auricular cartilage, and there was no connection with the overlying epidermis. CONCLUSIONS: This is a case report of an extraosseous cemento-ossifying fibroma of the auricle. This benign tumor should be completely excised because local recurrence may otherwise result.

6/118. Malignant eccrine poroma in an elderly African-American woman.

    BACKGROUND: eccrine porocarcinoma is a rare, slow-growing malignant tumor arising from the eccrine sweat gland. OBJECTIVE: We present a case of eccrine porocarcinoma of the ear in an elderly African-American woman. Cases of eccrine porocarcinoma have been reported in the literature occurring in facial, extremity, scalp, and genital sites and primarily in Caucasian patients. Rarely are cases described in African-American patients or on the ear. methods: We describe the history of the lesion, discuss the current cancer statistics for skin cancer in african americans, and histology and treatment choices are compared with previously reported cases. RESULTS: We present a case of malignant eccrine poroma of the ear in a 71 year old African-American woman. The tumor was completely excised by mohs surgery. Transposition flap repair of the Mohs surgical defect was performed. CONCLUSIONS: While african americans are at low risk of developing skin cancers, it is important to remember that skin cancers can affect patients of any ethnicity and skin tone. Treatment regimens for skin cancers in African-American patients must be chosen appropriately by site of tumor, size of tumor and extent of disease as would be expected for any skin cancer.

7/118. Squamous cell carcinoma of the external auditory canal: two cases treated with high dose rate 192Ir remote afterloading system (RALS).

    We report two cases of early-stage external auditory canal cancer treated by intracavitary irradiation with a high dose rate (HDR) 192Ir remote afterloading system (RALS) for preoperative treatment. A 6-Fr catheter for the HDR 192Ir remote afterloader, fixed by a plastic earplug, was inserted into the external auditory canal in two cases (case 1, T2N0M0; case 2, T1N0M0). The total intracavitary radiation dosages were 50 Gy (10 Gy/2 Fr/wk for 5 wks) for case 1, and 42 Gy (15 Gy/5 Fr/wk for 3 wks) for case 2. No external irradiation was given in either case. Surgical resection was performed in both cases, three to four weeks after irradiation. Histopathological examination confirmed the post-irradiation changes of necrosis, hyalinosis, and calcification, although vivid cancer cells remained. In preoperative irradiation of external auditory cancer, this method, although limited to treating early-stage cancers, may be a modality of choice for its efficacy and less severe side effects.

8/118. Malignant melanoma with liver and spleen metastases: case report.

    CONTEXT: The diagnosis of primary melanoma is easily confirmed after histological analysis of the lesion, whereas it is rarely diagnosed when the patient even has distant metastases. DESIGN: Case report CASE REPORT: Malignant melanoma is responsible for about 1% of all deaths caused by cancer in the USA and only 3% of all malignant skin diseases. Malignant melanoma is a rare disease, although it corresponds to 65% of all deaths caused by skin cancer. The liver and spleen are rarely the first sites of melanoma metastases. This paper reports on the clinical picture of a patient with fatal malignant melanoma and hepatic and spleen metastases. As this was an un-usual presentation, the melanoma diagnosis could only be made after pathological analysis of the skin and hepatic lesions.

9/118. Mature teratoma of the middle ear.

    OBJECTIVE: The authors report a case of mature teratoma of the middle ear in a 3-year-old girl with a 1-year history of otitis media. methods AND RESULTS: Radiologic investigation revealed a partially cystic lesion of the petrous portion of the right temporal bone. It produced opacification of the middle ear as well as destruction of septal air cells. The patient underwent a subtotal petrosectomy. Histologically, the tumor was composed of an intimate admixture of mature tissues representing all three germ layers, including brain, myelinated nerve trunks, skeletal muscle, bone, immature cartilage, seromucinous glands, and respiratory epithelium. Of note within the brain tissue was choroid plexus within an ependyma-lined rudimentary ventricle. Immunohistochemical studies were also performed. Twenty months after surgery, the patient was well, with complete recovery from symptoms. CONCLUSION: Teratomas of the middle ear are rare neoplasms. Only a few examples have been reported. As a rule, they are cured by resection and do not require adjuvant therapy.

10/118. Aspiration cytopathology of middle-ear neuroendocrine carcinoma.

    Primary neuroendocrine carcinoma (carcinoid tumor) is among the rarest of middle-ear (ME) neoplasms, with only a rare case of metastatic disease having been reported. Fine-needle aspiration biopsy (FNAB) was performed in a 51-yr-old male with a two-decade history of multiple local recurrences from a right middle-ear neoplasm, with the most recent surgical excision 2 yr ago. He currently presented with an enlarged right parotid gland, and a right infratemporal mass. Aspirate smears showed a monotonous population of cytologically bland cells with a small to moderate amount of pale granular cytoplasm, round to oval nuclei, inconspicuous nucleoli, and finely granular chromatin. Rare, isolated large cells were occasionally seen. Immunohistochemical staining of the cell block made from the aspirated material showed strong cytoplasmic positivity for chromogranin, synaptophysin, neuron-specific enolase (NSE), serotonin, and cytokeratin cocktail, and negative staining for S100 protein. review of tissue slides from the patient's prior middle-ear tumor showed an identical immunoprofile and morphology, and led to a revision of the original diagnosis of paraganglioma. Middle-ear neuroendocrine carcinoma has a low but definite metastatic potential, which can be diagnosed using FNAB if ancillary immunohistochemical studies are available.
