RESUMEN
Introduction: Ectopic parathyroid glands have been reported with an incidence of 2-22%. Undescended parathyroid glands, defined as glands situated above the carotid bifurcation or > 1 cm cranial to the superior pole of the thyroid gland, comprise 2-7% of all ectopic parathyroid glands. We report a case of incidentally discovered parathyroid gland located in the retropharyngeal space at the level of the oropharynx. Case Presentation: The patient in this report was a 60-year-old female with squamous cell carcinoma of the tonsil T2N0M0 with MRI showing a hyperintense ovoid structure, medial to the carotids at the level of the oropharynx, corresponding to the location of the lateral group of retropharyngeal lymph nodes. Patient underwent transoral ultrasonic radical tonsillectomy along with a retropharyngeal lymph node dissection by the transcervical route. Postoperative histopathology revealed the retropharyngeal node sampled to be a normal parathyroid gland. Discussion: "High" undescended parathyroid gland as reported here along with 4 other cases of infratemporal fossa parathyroid glands reported previously, can be the cause for recurrent missed adenomas. Being extracervical in location, these are likely to be missed if the skull base has not been included in the preoperative Tc-99 sestamibi scan and also during bilateral neck exploration.
RESUMEN
OBJECTIVES: Perimarginal nodes (PMN) lie in close relationship with marginal mandibular nerve (MMN), in the lymphatic drainage pathway of gingivo-buccal cancers (GBC), above the lower border of mandible and remain unaddressed in conventional neck dissection. We have aimed to define the boundaries of perimarginal node dissection, explore incidence of PMN metastasis and its correlation with histopathological characteristics. MATERIALS AND METHODS: A prospective study was conducted on 112 consecutive patients of GB carcinoma. PMN dissection was performed in an anatomically defined quadrangle. Prospective clinical characteristics included subsite, tumor and nodal stage, location of primary and clinical skin involvement. Histopathological characteristics analyzed included grade, size, pathological tumor, nodal stage, skin and/or bone involvement, depth of invasion, Brandwein Gensler histological risk score and lympho-vascular emboli. MMN function was graded at 3 and 6 months post-operatively. RESULTS: The PMN were identified histologically in 75.89 % patients. 15.2 % patients harboured metastasis in PMN. 16.7 % patients had clinically occult metastasis with 11.7 % having isolated PMN metastasis. None of the pre-operative clinical factors was found to be significant in predicting incidence of metastasis. Higher nodal burden (p = 0.01) and pathological skin involvement (p = 0.03) were found statistically significant on multivariable analysis. At 6 months follow-up, none of the patients had any MMN functional deformity at rest. CONCLUSION: There is a high incidence of occult PMN metastasis from gingivo-buccal complex cancer. High nodal stage and pathological skin involvement are independent predictors for PMN metastasis. PMN dissection must be performed in all cases of GB cancer.
RESUMEN
BACKGROUND: Marjolin ulcer (MU) is an aggressive cutaneous malignancy that commonly occurs in those with a chronic wound such as post-burn scar. CASE REPORT: A 20-year-old male who sustained a flame burn over the scalp at 3 months of age developed a nonhealing ulcer over the burn scar 20 years later, which was treated with adequate surgical margins with adjuvant mold brachytherapy. Two months after completion of that treatment, he developed parotid nodal metastasis with positron emission tomography (PET)-positive bilateral cervical, supraclavicular, right suboccipital, and mesenteric lymph nodes that were treated with concurrent chemoradiation. One month later, the patient developed an ulcerative lesion involving the left parotid region with PET showing infiltration of the parotid gland, but with resolution of other previous sites of uptake. The patient was treated surgically with radical parotidectomy with elective neck dissection and reconstruction with locoregional flap. At 6-month follow-up, the patient developed extensive locoregional recurrence and distant metastasis and was started on oral metronomic therapy. The patient was alive with stable disease at 3-month follow-up after initiation of palliative chemotherapy. CONCLUSION: Despite timely multimodality therapy, MU may present with a hostile clinical course with a short disease-free interval and early recurrence.

OBJECTIVE: To determine if systemic administration of low-molecular-weight heparin impacts venous compromise in loco-regional flap reconstruction for head and neck subsites. METHODS: This prospective study was conducted on patients who had developed features of venous compromise of the flap. The case group received low-molecular-weight heparin (dalteparin). RESULTS: Of the 73 patients who developed venous congestion, low-molecular-weight heparin was administered in 47 patients. In the low-molecular-weight heparin subset, 23 patients had either reversal or non-progression of venous compromise (48.9 per cent). Of the patients who had no response to low-molecular-weight heparin rescue, complete necrosis was seen in 4 and partial flap necrosis was observed in 19. The corresponding numbers in the control group were 13 and 12, respectively (odds ratio 23.9, p = 0.002). Additionally, the low-molecular-weight heparin arm had a lower incidence of partial or complete flap necrosis (p = 0.002). CONCLUSION: Low-molecular-weight heparin salvage, when instituted early, is likely to result in a significant reduction in flap-related morbidity.
RESUMEN
Full thickness defects following surgical resection of locally advanced carcinoma buccal mucosa involving oral commissure often require complex microvascular procedures that are technically demanding. We present a novel technique of folded pectoralis major myocutaneous flap for reconstruction of such defects without the need for free flaps or additional sling support.
RESUMEN
BACKGROUND: There exists a lacuna in the structured reporting of swallowing dysfunction and quality of life (QoL) outcome following major glossectomy. METHODS: Prospective cohort study to assess the swallowing dysfunction and QoL following STG (subtotal glossectomy) or NTG (near total glossectomy) over a 6-month period using FEES and PAS scale, MDADI, and FACT-HN. RESULTS: Twenty-four patients were available for analysis. The pre- and post-adjuvant evaluation revealed a statistically significant improvement in the composite MDADI and FACT-HN scores. Subscale analysis of FACT-HN scores revealed maximum deficit in the head and neck cancer-specific score domain followed by functional domain and social well-being domain, with serial improvement noted in the post-adjuvant setting. CONCLUSION: This study showed serial improvement in terms of swallowing dysfunction although social and functional well-being domains related to QoL continued to reveal major deficits. Better outcomes were seen with preservation of bilateral base of tongue and mandible.

Introduction: Gingivo-buccal complex cancers (GBCC) have an aggressive clinical course in the presence of skin and bone involvement.ObjectiveThis study intends to analyze the clinico-pathological factors affecting local control and survival outcomes in GBCC.MethodsThis is a retrospective study conducted on 125 GBCC cases from January 2011 to April 2016.ResultUnivariate analysis revealed lymphovascular invasion (LVI) and skin involvement as predictors of poor overall survival (OS) and disease- free survival (DFS). Multivariate analysis showed skin involvement and LVI to be independent prognostic factors towards poor OS. Corresponding results in case of DFS showed skin involvement to be the single most important prognostic factor. With a median follow up of 24 months, the median survival of patients with skin involvement, skin and mandible invasion and isolated mandible invasion, respectively, were 18 months, 12 months and 22 months.ConclusionGBCC with skin involvement portends poor outcome in terms of survival. In the presence of skin invasion, treatment entails liberal soft tissue and bone margin followed by adjuvant treatment. (AU)
Introducción: Los cánceres del complejo gingivo-bucal (GBCC) tienen un curso clínico agresivo en presencia de afectación de la piel y los huesos.ObjetivoEste estudio pretende analizar los factores clínico-patológicos que afectan al control local y los resultados de supervivencia en GBCC.MétodosEste es un estudio retrospectivo realizado en 125 casos de GBCC desde enero del 2011 hasta abril del 2016.ResultadoEl análisis univariado reveló la invasión linfovascular (LVI) y la afectación de la piel como predictores de una supervivencia general pobre (SG) y una supervivencia libre de enfermedad (SSE). El análisis multivariado mostró que la afectación de la piel y el LVI son factores pronósticos independientes hacia una SG pobre. Los resultados correspondientes en caso de SSE mostraron que la afectación de la piel es el factor pronóstico más importante. Con una mediana de seguimiento de 24 meses, la mediana de supervivencia de pacientes con afectación cutánea, invasión de la piel y la mandíbula e invasión aislada de la mandíbula, respectivamente, fue de 18 meses, 12 meses y 22 meses.ConclusiónEl GBCC con afectación de la piel presagia un mal resultado en términos de supervivencia. En presencia de invasión de la piel, el tratamiento implica unos márgenes de tejidos blandos y oseos amplios seguido de un tratamiento adyuvante. (AU)
