RESUMO

Keratoacanthoma is an epithelial tumour derived from hair follicles. Clinical and histopathological features of keratoacanthoma can resemble that of squamous cell carcinoma. Different treatment alternatives have been described over the years including intralesional methotrexate injection. We present an interesting case of treatment of solitary keratoacanthoma lesion on the nose with intralesional methotrexate as non-surgical therapy.

RESUMO

In box genioplasty it is possible to advance, retrude, impact, and elongate, as well as to correct asymmetry. The aim of this study was to analyse the stability of box genioplasty as part of orthognathic correction. Twenty-five consecutive patients who had gone through the multidisciplinary pathway were selected. Menton and pogonion positions on radiographs taken just prior to surgery, and actual surgical movement on three-week and 12-month postoperative cephalograms, were compared. A one-sample Wilcoxon test was applied to assess whether the distributional change in advancement and vertical measurements was equal to zero. After treatment, anteroposterior changes in pogonion and vertical changes in menton were statistically insignificant (p>0.05). Our study demonstrated statistically significant stability of menton and pogonion positions after box genioplasty when surgical movement was only in the symphysis.

RESUMO

Orthognathic surgery is a well-recognized method to correct dentofacial deformities. The main goal of orthognathic surgery is to improve soft tissue change. Soft tissue changes to the nose have been well documented. Simultaneous rhinoplasty during orthognathic surgery can be performed to correct existing inherent nasal deformities and also the unfavorable changes that arose from the maxillary surgery. Challenges for concurrent nasal surgery with jaw surgery include preoperative, perioperative, and postoperative which can be overcome with meticulous planning and experience. In complex cases, rhinoplasty can be staged in the last 6 months after the orthognathic surgery.

RESUMO

Signet-ring cell (histocytoid) carcinoma is a rare and aggressive skin neoplasm that most commonly affects elderly men. It typically originates from the upper or lower eyelid, with bilateral involvement only in rare cases, and results in a diffuse and infiltrative appearance clinically, radiologically, and histologically (the "monocle" sign). It is essential to carry out a full investigation to rule out metastasis from an internal origin.

RESUMO

Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer of neuroendocrine origin. As a result, few large studies have been published, and we know of even fewer on disease of the head and neck alone. The most appropriate way to manage patients with early local disease and no sign of metastases neck is controversial. We reviewed management of early cutaneous MCC of the head and neck in 8 hospitals in the United Kingdom over 12 years between 1999 and 2011 (the largest head and neck series in Europe to date), and identified 39 patients (19 men and 20 women) with early disease according to a well recognised classification. A total of 24 patients had stage Ia disease, 11 had stage Ib disease, and 4 were unclassified. Five of those with stage Ia disease developed regional metastases and 7 with stage Ib disease developed regional recurrence. The 2-year overall survival for stage Ia and Ib disease was 62% and 27%, respectively. Our study shows that prognosis is poor after conservative surgical management of stage I disease. Management of the neck is still controversial, and a meta-analysis of all the published data is needed to establish best practice statistically.

RESUMO

Traditional open operations for lateral neck dissection in patients with papillary thyroid carcinoma leave an unsightly scar. We report complete lateral neck dissection and thyroidectomy for papillary thyroid carcinoma using an endoscopically-assisted approach through a small incision, and evaluate its feasibility and safety. Between March 2010 and January 2013, 6 patients with no definite metastases to the lymph nodes at levels II-IV, and 20 with definite metastases to the lymph nodes at levels II-V were selected. Thyroidectomy, dissection of the central compartment (level VI), and ipsilateral level II-IV and II-V neck dissections were done through a small incision in the neck. The steps of endoscopic lateral neck dissection were similar to those of conventional operations. The mean operating time for the whole procedure was 3.57 hours (range 2.5 - 5.0). It was successful in all patients and there were no serious complications or serious blood loss. A total of 21 patients had lymph node metastases in the central and lateral zones. The mean yield of lymph nodes was 38.6 (range 16-61). There was no evidence of residual or recurrent disease at follow-up, and the cosmetic result was excellent. Minimally invasive, video-assisted comprehensive neck dissection for metastatic papillary thyroid carcinoma is feasible and safe, and has excellent cosmetic results. Further studies with a larger number of patients and long-term follow-up are needed to verify its oncological validity.

RESUMO

Paralysis of the hypoglossal nerve, the twelfth (XII) cranial nerve, leads to atrophy, deviation of the tongue to the affected side, and varying degrees of fasciculation. The injury to the nerve can occur from its origin to the tongue itself. The causes of hypoglossal nerve palsy are well documented, but idiopathic, isolated nerve palsy that does not recover, is rare. To our knowledge we describe the first case that failed to resolve, and discuss the importance of meticulous investigation to make a diagnosis and rule out sinister disease.

RESUMO

PURPOSE: Atypical fibroxanthoma is a cutaneous dermal malignancy that presents on the sun-damaged skin of elderly people. It requires a definitive diagnosis, from a high-grade sarcoma to a nonmesenchymal neoplasm. The recommended treatment protocol differs from similar histologically related tumors; thus, a diagnosis of atypical fibroxanthoma should fulfill strict histologic and immunohistochemical stain criteria. The use of these standards will exclude other skin malignancies, including malignant fibrous histiocytoma, angiosarcoma, malignant melanoma, and squamous cell carcinoma. This study was performed with the aim of identifying key immunostains to develop diagnostic criteria. MATERIALS AND METHODS: Forty-two cases were studied retrospectively over a 10-year period using a panel of immunostains. RESULTS: The average age at presentation was 78 years, with a male predominance. The scalp was found to be the most common site of occurrence, although other investigators have found the forehead, cheeks, nose, and ears as the prevailing sites of presentation. CONCLUSIONS: An extensive panel of immunohistochemical stains can be used to prove a diagnosis of atypical fibroxanthoma.

RESUMO

Orthognathic surgery is a recognised way of correcting dentofacial deformities and it is common practice to treat problems that affect the chin simultaneously, while deferring or not treating nasal deformities. There is inadequate published information about the prevalence of nasal deformities in such patients, and our aim was to remedy this. We retrospectively studied 75 patients with dentofacial deformities to find out if there was an association between nasal and dentofacial abnormalities. Forty-six of the 75 patients (61%) had mild to prominent cosmetic nasal problems, of whom 27 had deformities of the nasal bridge, 22 of the lobule of the nasal tip, 20 of nasal width, 14 in the width of the alar base, and 11 of the columella; 8 presented with deviation of the nose, and 6 with abnormal nasal length. Skeletal classes II and III had only slightly varied emphasis on nasal deformities. In comparison 14 patients (19%) had problems with the chin that required, or had already had, genioplasty. We also studied 9 patients who had had corrective bimaxillary surgery with simultaneous rhinoplasty. We set no formal questionnaire, but all patients expressed satisfaction with the postoperative results.

RESUMO

The lateral brow generally becomes ptotic earlier than the medial brow, and many techniques have been described to raise it. We describe a simple technique, which does not require expensive equipment such as an endoscope or fixation devices and reduces the risks that arise from large incisions and extensive dissection.

RESUMO

Trends in the incidence and the sites of primary malignant melanoma on the skin of head and neck in Dorset as well as the outcome of treated cases were overviewed for the first time. Increase in incidence rate of cutaneous head and neck melanoma from 1.3 per 100,000 in 2004 to 3.1 per 100,000 in 2007 was recorded. The most prevalent histogenetic type of cutaneous malignant melanoma on head and neck in our study was melanoma of superficial spreading type 35.1% (n=20) of all registered cases. Superficial spreading melanoma apart from being the most common type of malignant melanoma of the head and neck in Dorset also showed increase in the number of diagnosed cases of the reviewed years. It increased from 2 (22.2%) of all head and neck melanoma cases in 2004 to 7 (30.4%) in 2007. The average age at the time of diagnosis the cutaneous malignant melanoma of head and neck for both men and women was 73.5 years. Breslow thickness, Clark's level of invasion, tumour ulceration and anatomical site remained the most important prognostic factors. Correlation between Breslow thickness and Clark's level of invasion found to be stronger in men.

RESUMO

Granulocytic sarcoma (GS) is a rare localized, extramedullary tumor composed of immature cells of granulocyte series. It is capable of marked local tissue destruction. This condition can be a precursor of acute myeloid leukaemia by months or years making its diagnosis critical. Its occurrence has been described in multiple sites including skin, lymph nodes, bone, and visceral organs. It is extremely rare in the oral cavity and only 30 cases have been reported in the literature to date and often as a lump in the gingiva, palate, and extraction sockets. We describe the first reported case of GS presenting as a solitary lump in the lip and review the pertinent literature.
