11/2475. Camouflage in head and neck region--a non-invasive option for skin lesions.

    The technique of camouflage, a non-invasive procedure to correct flaws in the texture and colour of the facial skin, is presented. The acceptance and use of camouflaging by 52 patients with different diagnoses are presented. The advantages of camouflaging are discussed in comparison to medical tattooing. ( info)

12/2475. Cervical teratoma.

    Cervical teratomas are rare tumors in an unusual location. A neck mass in a newborn was excised when it enlarged disproportionately; histologically, it was a teratoma. Teratomas may occur because of an alteration in sterol chemistry; conception in this case occurred while the mother was ingesting estrogens. Retinal tissue, an unusual finding, was present in this teratoma. Symptoms in cervical teratomas are secondary to interference with deglutition and respiration. Treatment is surgical excision.

13/2475. The sternomastoid "tumor" of infancy.

    The sternomastoid "tumor" of infancy is a firm, fibrous mass, appearing at two to three weeks of age. It may or may not be associated with torticollis. Generally, the "tumor" initially grows, then stabilizes, and in about half the cases recedes spontaneously after a few months. It may leave a residual torticollis or may be associated with a facial or cranial asymmetry of a delayed torticollis. The etiology is unknown, a direct cause and effect relationship to birth trauma has been largely disproved although approximately half these children are products of breech deliveries. The treatment is controversial. Approximately half of these "tumors" will resolve spontaneously without sequelae. Progressive torticollis or development of facial asymmetry are considered indications for surgery. The purpose of this report is to acquaint the head and neck surgeon with this entity which may confront him for diagnosis and treatment. ( info)

14/2475. MRI and ultrasound guided interstitial Nd:YAG laser phototherapy for palliative treatment of advanced head and neck tumors: clinical experience.

    Interstitial laser phototherapy (ILP) is a technique whereby laser energy is directly applied into tumors at variable depths. This technique is attractive, since it is minimally invasive and carries a low morbidity. It may allow treatment of deep and difficult to reach tumors in the head and neck and other areas when improved noninvasive monitoring techniques of laser-tissue interactions are developed. Recent studies demonstrate, respectively, the efficiency of ultrasound (UTZ) and magnetic resonance imaging (MRI) for real time interstitial needle placement in tumors, identification of vessels, monitoring and quantifying laser-induced tissue damages. We present a case in which a patient with recurrent, metastatic base of skull carcinoma has managed successfully with repeat ILP using MRI and UTZ guidance. Under heavy sedation, needles were placed in the tumor using MRI or UTZ guidance. Tumors were treated with a 600 mum flexible Nd:YAG laser fiberoptic passed through the needles. Laser-induced tissue photoablation was monitored using real time color flow Doppler UTZ or near real time fast spin-echo T2-weighted MRI. Posttreatment fine needle aspiration cytologic study demonstrated the presence of cellular debris and no viable cancer cells. Posttreatment follow-up MRI scans showed significant reduction of tumor size, and positron emission tomography (PET) revealed interval decrease in tumor metabolism. Treatments were accompanied by pain relief and improved functional abilities. ILP has now evolved into minimally invasive outpatient surgical procedure.(ABSTRACT TRUNCATED AT 250 WORDS) ( info)

15/2475. Removal of catecholamine-secreting chemodectoma. The use of neuroleptanaesthesia, adrenergic blockade and sodium nitroprusside.

    A case of catecholamine-secreting chemodectoma of the neck in a 47-year-old male who also had temporal lobe epilepsy is described. Details of presentation, diagnosis and successful treatment are given. He was fully alpha blocked with phenoxybenzamine and given neuroleptic drugs but his blood pressure rose to dangerous levels when the tumour was handled and did not respond to intravenous phentolamine. sodium nitroprusside was successfully used to achieve blood pressure control.

16/2475. Vascular lesion of the masseter presenting with phlebolith.

    When evaluating an intramuscular soft tissue mass, a large differential diagnosis including both benign and malignant lesions must be considered. Because the treatment of these masses can range from simple observation to radical surgical excision, a minimally invasive but accurate method of diagnosis is desired. The workup should include radiographic imaging. MRI is the modality of choice for differentiating soft tissue lesions, although CT may be helpful in identifying calcifications such as a phlebolith. Although usually unnecessary, a sialogram can verify that a calcification lies within or outside the salivary ductal system. In most cases a biopsy specimen is required to confirm the diagnosis. However, if the imaging studies show characteristics consistent with a vascular soft tissue mass, the finding of a phlebolith is pathognomonic for a benign vascular lesion. If such a lesion is not causing significant cosmetic or functional disability, it can be observed without the need for invasive biopsy or treatment. ( info)

17/2475. HPV 18-induced pigmented bowenoid papulosis of the neck.

    We describe the case of a 53-year-old man in whom pigmented bowenoid papulosis developed on the skin of the neck. By polymerase chain reaction with general primers for genital human papillomaviruses (HPV) and subsequent restriction enzyme cleavage we could demonstrate HPV 18-related dna in two biopsy specimens of the pigmented papules. To our knowledge, this report represents the first case of HPV 18-induced extragenital bowenoid papulosis of the neck. ( info)

18/2475. Possible branchiogenic carcinoma coinciding with metastatic papillary thyroid carcinoma.

    We report the discovery of a cystic lesion of flat lining epithelium with areas of squamous carcinoma, associated with metastatic cervical nodes of a papillary thyroid cancer, and discuss the diagnostic possibilities. ( info)

19/2475. Metastatic basal cell carcinoma to the lung.

    Basal cell carcinoma is a relatively common tumor with an increasing incidence. Despite this, metastatic disease is an extremely rare event. A review of metastatic basal cell carcinoma is presented. ( info)

20/2475. Unusual presentation of a salivary pleomorphic adenoma: a case report and review of the literature.

    Although pleomorphic adenomas are the most common neoplasms of salivary gland origin, our knowledge of the etiology, growth, and recurrence patterns, and significance of the varying histologic features of these tumors, remains limited. We present the case of a 66-year-old man with an unusual presentation of a pleomorphic adenoma, and review the important clinical and pathologic features of this entity. ( info)
