Diagnostic relevance of metastatic renal cell carcinoma in the head and neck: An evaluation of 22 cases in 671 patients

ABSTRACT Purpose Renal cell carcinoma (RCC) is a malignant tumor that metastasizes early, and patients often present with metastatic disease at the time of diagnosis. The aim of our evaluation was to assess the diagnostic and differential diagnostic relevance of metastatic renal cell carcinoma (RCC) with particular emphasis on head and neck manifestations in a large patient series. Patients and methods We retrospectively evaluated 671 consecutive patients with RCC who were treated in our urology practice between 2000 and 2013. Results Twenty-four months after diagnosis, 200/671 (30%) of RCC had metastasized. Distant metastases were found in 172 cases, with 22 metastases (3.3%) in the head and neck. Cervical and cranial metastases were located in the lymph nodes (n=13) and in the parotid and the thyroid gland, tongue, the forehead skin, skull, and paranasal sinuses (n=9). All head and neck metastases were treated by surgical excision, with 14 patients receiving adjuvant radiotherapy and 9 patients receiving chemotherapy or targeted therapy at some point during the course of the disease. Five patients (23%) survived. The mean time of survival from diagnosis of a head and neck metastasis was 38 months, the shortest period of observation being 12 months and the longest 83 months. Discussion and conclusion Our findings show that while RCC metastases are rarely found in the neck, their proportion among distantly metastasized RCC amounts to 13%. Therefore, the neck should be included in staging investigations for RCC with distant metastases, and surgical management of neck disease considered in case of resectable metastatic disease. Similarly, in patients presenting with a neck mass with no corresponding tumor of the head and neck, a primary tumor below the clavicle should be considered and the appropriate staging investigations initiated.

Single cutaneous metastasis of colon adenocarcinoma - Case report

Abstract: Skin metastases are relatively rare and occur most often when the cancer is already advanced, invading other organs. As to location, they often seem to elect areas located close to the primary tumor, although distant sites, such as the scalp, may be affected with some frequency. We present a case of a 76-year-old woman with colon adenocarcinoma that had a single metastatic lesion on the scalp.

Incremental (?) role of positron emission tomography/computed tomography in clinically unknown primary patients with neck metastasis.

OBJECTIVE: To study the incremental role of positron emission tomography (PET)/computed tomography (CT) in the detection of primary site in cases of occult primary with neck metastasis. STUDY DESIGN: A prospective study on 79 consecutive patients. SETTING: A tertiary care otolaryngology and head and neck surgery center. MATERIALS AND METHODS: This prospective study compares the results of PET/CT in 79 patients of occult primary with neck metastasis with that of detailed comprehensive head and neck examination including imaging and panendoscopy. This study also attempts to define the incremental role of PET/CT in patients of occult primary. RESULTS: The sensitivity of PET/CT in identifying the primary tumor was 62.4%, the specificity was 64.7%, the positive predictive value was 69.7% and the negative predictive value was 93%. We had a false positive rate of 33.6% and a false negative rate of 2.6%. CONCLUSION: PET/CT is a sensitive investigation for detection of occult primary. However, it has a low specificity rate and a high false positivity rate. Due to a high false positive rate, multiple biopsies from suspicious sites should be taken rather than solely relying on PET/CT. PET/CT guided fine needle aspiration cytology should be utilized more frequently than we did in this study.

O impacto do nível da metástase cervical no prognóstico dos pacientes com carcinoma epidermoide de cavidade oral / Prognostic impact of the level of neck metastasis in oral cancer patients

Em pacientes com carcinoma epidermoide oral, classifica-se o pescoço pelo número, tamanho e lateralidade das metastáses. OBJETIVO: Avaliar fatores de risco para metástase em nível IV/V e seu impacto no prognóstico do carcinoma epidermoide oral. MÉTODO: Estudo retrospectivo. Critérios de inclusão foram: diagnóstico de CEC, sítio primário em andar inferior da boca sem extensão para sítios extraorais, ausência de tratamento prévio, realização de EC e presença de metástases linfáticas. Por regressão logística, definiram-se fatores de risco e por análise de sobrevivência, fatores prognósticos de recorrência. Análise classificatória realizada por particionamento recursivo. RESULTADOS: Foram incluídos 307 pacientes. Em regressão logística univariada, o estágio pN, embolização vascular, e múltiplos linfonodos comprometidos foram fatores de risco para metástases em nível IV/V. Embolização vascular e múltiplos linfonodos comprometidos permaneceram significativos em análise multivariada. A análise de sobrevivência demonstrou os estágios pT e pN, infiltração perineural, embolização vascular, número de linfonodos metastáticos, razão linfonodal e metástases em níveis IV/V como significativos. Na análise multivariada, PT, pN, embolização vascular linfática e metástases em níveis IV/V permaneceram significativas. Na análise classificatória, o estágio pN não foi significativo quando há metástases em níveis IV/V. CONCLUSÃO: A ocorrência de metástases em níveis IV/V foi significativa para sobrevivência doença-específica.

Neck staging in oral cancer depends on the number of compromised nodes, their size and side of occurrence. OBJECTIVE: This paper aims to evaluate risk factors for metastatic nodes in levels IV/V and their prognostic impact on patients with oral carcinoma. METHOD: Retrospective study. Inclusion criteria: pathologist's diagnosis of squamous cell carcinoma, primary tumor in the lower oral cavity, no extension into extraoral sites, no previous treatment, synchronous neck dissection and presence of metastatic nodes. Risk factors for metastasis were evaluated through logistic regression and disease-specific survival and recurrence by survival analysis. Classificatory analysis was performed through recursive partitioning. RESULTS: 307 patients met the inclusion criteria. Univariate logistic regression identified pN stage, vascular invasion, and multiple metastatic nodes as risk factors for metastases in levels IV/V. Multivariate analysis found vascular invasion and multiple metastatic nodes were significant. Survival analysis revealed pT, pN, neural infiltration, vascular invasion, number of metastatic nodes, metastases in levels IV/V, and node ratio were significant factors. In multivariate survival analysis, pT, pN, vascular invasion and metastases in levels IV/V were significant. Classificatory analysis showed that pN is non-significant in patients with level IV/V metastases. CONCLUSION: The occurrence of metastases in levels IV/V was significant for disease-specific survival.

Role of ultrasound in detection of metastatic neck nodes in patients with oral cancer.

Introduction: Head and neck cancer is one of the most physically and emotionally devastating cancers and often leaves the patient disabled and disfigured. The presence of cervical metastasis is one of the factorsthat influence the outcome of the patients. Cervical lymph node metastasis plays an essential role in the treatment and prognosis of head and neck cancer patients. The assessment of the cervical lymph node status still remains an unsolved problem. We conducted a study to compare the diagnostic accuracy of clinical palpation and ultrasonogram (USG) in the detection of metastatic cervical nodes from oral squamous cell carcinoma patients. Materials and Methods: Ten patients (age range, 45-63 years; mean age, 54 years) with squamous cell carcinoma in the head and neck region underwent clinical palpation and USG. The results of each modality were analyzed for sensitivity, specificity, positi ve predictive value, negative predictive value and accuracy. Pathologic analysis of the surgical resection served as the reference standard. Results: USG yielded a sensitivity, specificity, positive, negative predictive value and accuracy as 85.7%, 90%, 92.3%, 81.8% and 87.5% whereas clinical palpation yielded a sensitivity, specificity, positive, negative predictive value and accuracy as 68.7%, 87.5%, 91.6%, 58.3% and 75%. Conclusion: USG is a reliable and valuable tool for metastatic lymph node screening in head and neck cancer patients. It is a cheap, noninvasive, easy-to-handle and cost-effective diagnostic method. USG performed better than clinical palpation in detecting cervical metastatic nodes.

Utility of PET in unknown primary with cervical metastasis: A retrospective study.

Background: FDG-PET is recommended as an investigation in unknown primary tumors, but its definitive role and cost effectiveness are yet to be established. Aims: dditional value of FDG-PET over conventional imaging in unknown primary tumors with cervical metastasis. Setting and Design: Retrospective study in a tertiary level oncology centre. Materials and Methods: A total of 112 patients were divided into three groups; 53 with conventional modalities (either computed tomography or magnetic resonance imaging) (group I), 59 with FDG-PET (group II), and group III (subgroup of group II) with both (40 patients). Statistical Analysis: Sensitivity and specificity of both conventional modality and PET were calculated. Association between neck nodes and distant metastasis was analysed using multivariate logistic regression analysis. Results: Sensitivity and specificity for conventional modalities was 92.3% and 50% and sensitivity and specificity of FDG-PET was 92.8% and 71.4%, respectively. FDG-PET detected metastasis in 52.54% of patients. Multivariate logistic regression analysis showed statistically significant association between distant metastasis and multiplicity of nodes (N2b, N2c) (P = 0.007). Among all patients with low neck nodes in group II, FDG-PET detected primaries in 12 patients, 9 of which were infraclavicular (75%). FDG-PET added information to conventional imaging in 32.5% of patients and influenced an overall change in management in 38.9% of patients. Conclusions: FDG-PET is a valuable tool influencing change of management in unknown primary with cervical metastasis. It is recommended especially in the presence of low or multiple neck nodes in view of high incidence of infraclavicular primary and distant metastasis, respectively.

Perioperative anesthetic management of patients with hypertrophic cardiomyopathy for noncardiac surgery: A case series.

Hypertrophic cardiomyopathy with or without left ventricular outflow tract obstruction is characterized by asymmetric hypertrophy of the interventricular septum causing intermittent obstruction of the left ventricular outflow tract. Because Hypertrophic cardiomyopathy is the most common genetic cardiovascular disease, it may present to the anesthesiologist more often than anticipated, sometimes in undiagnosed form during routine preoperative visit. Surgery and anesthesia often complicate the perioperative outcome if adequate monitoring and proper care are not taken. Therefore, a complete understanding of the pathophysiology, hemodynamic changes and anesthetic implications is needed for successful perioperative outcome. We hereby describe the perioperative management of three patients with Hypertrophic cardiomyopathy for different surgical procedures.

Investigação de linfonodos em pacientes em seguimento por carcinoma diferenciado de tiróide / Cervical lymph nodes metastases in patients with differentiated thyroid cancer

Recorrências regionais dos carcinomas diferenciados de tiróide (CDT) são representadas por linfonodos cervicais em 60-75 por cento dos casos. Com a introdução da ultra-sonografia cervical (USC) no seguimento dos pacientes com carcinoma papilífero de tiróide (CPT) tornou-se freqüente o encontro de pequenos linfonodos (LNs) cervicais. Porém, apesar da USC apresentar alta sensibilidade, o estudo citológico obtido por punção aspirativa (PAAF), e nos últimos anos, a dosagem da tiroglobulina (Tg) no lavado da agulha da PAAF (Tg-PAAF), vêm assumindo papel importante no diagnóstico de LNs cervicais. O objetivo deste estudo é revisar a importância do diagnóstico precoce das metástases em linfonodos cervicais no seguimento dos pacientes com carcinoma de tiróide.

Loco-regional recurrences of the differentiated thyroid cancer have been reported to be located in cervical lymph nodes in 60-75 percent of cases. The widespread use of neck ultrasonography (US) during the follow-up of patients with papillary thyroid carcinoma (PTC) has led to the discovery of small cervical lymph nodes (LN). Although US has a high sensitivity for diagnosing LN, fine needle aspiration biopsy (FNA) and measurement of thyroglobulin in fine needle aspirates (FNA-Tg) have proven to be invaluable tools. The aim of this paper is to review the importance of the early diagnosis of lymph node metastases in the follow-up of patients with differentiated thyroid cancer.

Diagnóstico de metástases de carcinoma papilífero de tiróide através da dosagem de tiroglobulina no líquido obtido da lavagem da agulha utilizada na punção aspirativa / Diagnosis of metastases in patients with papillary thyroid cancer by the measurement of thyroglobulin in fine needle aspirate

Com a introdução da ultra-sonografia cervical (USC) no seguimento dos pacientes com carcinoma papilífero de tiróide (CPT), tornou-se freqüente o encontro de pequenos linfonodos (LNs) cervicais. Porém, apesar de a USC apresentar alta sensibilidade, o estudo citológico obtido por punção aspirativa (PAAF) e, nos últimos anos, a dosagem da tiroglobulina (Tg) no lavado da agulha da PAAF (Tg-PAAF) vêm assumindo papel importante no diagnóstico de LNs cervicais. O objetivo deste estudo é verificar a acurácia da combinação da USC, citologia e Tg-PAAF em LNs suspeitos. Estudamos 32 pacientes que apresentavam 44 LNs à USC, classificados como "inflamatórios" (19) ou "suspeitos" (25). Dos 25 LNs suspeitos, 15 apresentavam Tg-PAAF elevada (13 com citologia compatível com metástases e 2 com citologia não-diagnóstica). Esses 15 LNs (11 pacientes) foram confirmados como metástase de CP pelo exame histopatológico. Os 19 LNs "inflamatórios" e os 10/25 LNs "suspeitos" apresentaram citologia negativa e Tg-PAAF indetectável. Concluímos que a USC apresenta alta sensibilidade na detecção de linfonodos cervicais, porém citologia e dosagem de Tg-PAAF são fundamentais para o diagnóstico. A associação USC, citologia e Tg-PAAF pode ser considerada a abordagem mais sensível e específica na detecção de LNs metastáticos em pacientes com CPT.

The widespread use of neck ultrasonography (US) during the follow-up of patients with papillary thyroid carcinoma (PTC) has led to the discovery of small cervical lymph nodes (LN). Although US has a high sensitivity for diagnosing LN, fine needle aspiration biopsy (FNA) and measurement of thyroglobulin in fine needle aspirates (FNA-Tg) have proven to be invaluable tools. The aim of this study is to determine the sensitivity of the combined use of neck US, FNA biopsy and FNA-Tg for diagnosis of cervical lymph nodes. We have studied 32 patients with 44 LN detected by US, 19 classified as inflammatory and 25 as suspicious. 15 of those 25 suspicious LN had high FNA-Tg (13 of the 15 had positive cytology and 2 indeterminate). All of these 15 LN (11 patients) were proven to be PTC metastasis by histopathology. All 19 inflammatory LN and those 10/25 suspicious LN, had cytology negative for malignancy and undetectable FNA-Tg. We conclude that fine needle aspiration biopsy and FNA-Tg combined with neck US are essential for detecting positive cervical lymph nodes due to its high sensitivity and specificity and it should be considered the standard for investigating locally recurrent disease in patients with PTC.

Cisto cervical: maligno ou benigno? / Cervical cyst: malignant or benign?

Introdução: o carcinoma papilífero da tireóide pode apresentar-se a partir de uma metástase cervical. A presença de metástase cística cervical pode ser confundida com lesão benigna e postergar o tratamento adequado do carcinoma papilífero. Relato de caso: esse fato ocorreu com o caso apresentado o que nos trouxe ensinamentos. Trata-se de uma paciente jovem com lesão cervical cística há quatro anos, com ultra-sonografia compatível com lesão benigna. O exame histopatológico pós-operatório diagnosticou metástase de carcinoma papilífero de tireóide. Em nova ultrasonografia, duas imagens nodulares menores que 1cm foram observadas na glândula tireóide. Discussão: a dificuldade de diagnóstico clínico, por imagem e por punção aspirativa por agulha fina das lesões císticas pode postergar o diagnóstico e, com isso, o tratamento. O caso aqui apresentado nos alerta de que não devemos aceitar ultra-sonografia cervical que não contenha o estudo da glâdula tireóide, principalmente quando forem formações que possam sifnificar metástases.

Introduction: the thyroi papillary carcinoma can present itself as cervical metastasis. The presence of cystic cervical metastasis can be confused with benign lesions and delay the treatment of papillary carcinoma. Case report: it occurred in the present case. We are reporting a cse of a young female patient with a cystic cervical lesion for four years with ultrasonography (US) diagnostic compatible to a benign lesion. The patient underwent surgical resection and the histopathological analysis diagnosed metastasis of thyroid papillary carcinoma. Another US identified two nodes smaller than 1cm in the thyroid gland. Discussion: the difficulty of clinical and radiological diagnosis and the limitation of fine needle aspiration cytology of the cervical cystic lesions can delay the diagnosis and treatment. The cervical US without study of the thyroid cannot be accepted, specially when there is the possibility of a cervical metasasis.

[ prevalence of occult neck metastasis in patients with N0 neck disease in squamous cell carcinoma of upper aerodigestive tract]

Cancers of head and neck can cause functional, cosmetic, social and economic problems. Neck metastasis from upper aerodigestive tract cancers is a concern in management. The aim of this study is to determine the occult neck metastasis from squamouse cell carcinoma [SCC] of upper aerodigestive tract and its proper management. This is a cross ' sectional study on patients with squamouse cell carcinoma of upper aerodigestive tract that hospitalized in departments of Otolaryngology Head and Neck Surgery and general surgery in Amir-alam referral hospital of Tehran University of Medical Scienses. 33% of patients were involved in occult metastasis in cervical lymph nodes. In 60% of patients more than one lymph node were involved. In the majority of patients tumor was in T2 stage. The occult neck metastasis was 24.6% in SCC of oral cavity, 44.7% in SCC of larynx and 42% in SCC of hypopharynx. There was significant relation between occult neck metastasis and T stage of tumor. When the risk of occult neck metastasis is higher than 20% and the primary site treatment modality is surgery elective neck dissection is indicated. In extracapsular spread or involvment of multiple lymph nodes with microscopic metastsis the postoperative radiation to neck is necessary

Occult metastasis in carcinoma of oral cavity

To determine the frequency of occult neck node metastasis in squamous cell carcinoma of oral cavity, in particular relation to the subsite and histopathological grading, and of involvement of the level of lymph nodes in the neck in oral cavity carcinoma. Descriptive study. Pakistan Institute of Medical Sciences, Islamabad and Wah Medical College, POP Hospital, Wah Cantt. from June 2000 to August 2006. Inclusion criteria were untreated carcinoma of oral cavity, not crossing midline, having NO neck. The tumors size more than T4 were excluded. All patients had ipsilateral type III modified radical [functional] neck dissection and lymph node groups were subjected to histopathology. Occult metastasis were found in 12 out of 37 cases [32.4%]. Metastasis in tongue carcinoma was 5/14, lower afveofar ridge carcinoma metastasized in 5/18, floor of mouth carcinoma was 2/4 and buccal mucosa carcinoma was 0/1.The percentage of occult metastasis in well-differentiated carcinoma [WDSCC], moderately differentiated carcinoma [MDSCC], and poorly differentiated carcinoma [PDSCC] were 22.2, 25% and 54.6% respectively. The levels of lymph nodes involved were level I [16.7%], level II [83.3%], level III [75.5%] and level IV [16.7%]. Oral cavity is a favourable site for metastasis to lymphatics even with small tumors. Occult metastasis is so frequent even with early carcinomas that neck should be treated with primary site. It is also important to remove level IV lymph nodes along with level I, II and III

Reatividade linfonodal e densidade microvascular nas metástases cervicais de carcinoma epidermóide com tumor primário oculto / Lymph node reactivity and microvessel density in neck metastases of unknown primary squamous cell carcinoma

INTRODUÇÃO: A neoangiogênese e a resposta imunológica são mecanismos importantes no desenvolvimento das metástases. OBJETIVO: Avaliar a reatividade linfonodal e a densidade microvascular nas metástases cervicais de carcinoma epidermóide com tumor primário oculto, considerando a sua relação com outras variáveis histológicas e clínicas. TIPO DE ESTUDO: Série de casos, retrospectiva. CASUíSTICA E MÉTODO: 19 pacientes submetidos a esvaziamento cervical entre 1983 e 2000. Os linfonodos foram reavaliados quanto ao tipo de reatividade, considerando a área cortical e paracortical. Nas metástases foi avaliado o grau de diferenciação, desmoplasia, necrose, e densidade microvascular (CD34). Foi estabelecida a relação entre as diferentes variáveis histológicas e clínicas, incluindo o estadiamento e a evolução dos pacientes. RESULTADOS: A densidade microvascular apresentou mediana de 91 vasos/mm2, variando de 28 a 145. A reatividade paracortical foi mais freqüente nos pacientes com menos de 55 anos (90 por cento x 44 por cento, p= 0,05). A sobrevida livre de doença foi de 52 por cento em 3 anos, sendo similar entre os pacientes com maior ou menor densidade microvascular tumoral. CONCLUSÕES: A densidade microvascular nas metástases de tumor primário oculto apresenta grande variação individual. Não foi possível estabelecer relação entre a densidade microvascular e as variáveis clínicas e histológicas estudadas.

BACKGROUND: neoangiogenesis and the immune response are important mechanisms in metastasis development. AIM: to evaluate lymph node reactivity and microvessel density in neck metastasis of occult primary squamous cell carcinoma considering their histological and clinical variables. STUDY DESIGN: retrospesctive case-series. METHOD: 19 patients with neck metastasis of occult primary squamous cell carcinoma who underwent neck dissection between 1983 and 2000 were selected. The lymph nodes were reevaluated on the type of reactivity in both the cortical and paracortical areas, and the metastasis were assessed as to grade, desmoplasia, necrosis and microvessel density (CD34). The relationship between histological and clinical variables was evaluated. RESULTS: the median microvessel density was 91 vessels/mm2, varying from 28 to 145. Paracortical hyperplasia was more common in patients below 55 years of age (90 percent x 44 percent, p= 0.05), but there was no relationship between reactivity patterns and microvessel density with prognosis. The disease-free survival was 52 percent in 3 years, being similar in both groups, with higher or lower microvessel densities. CONCLUSION: microvessel density in neck metastasis of occult primary squamous cell carcinoma had a great individual variability. It wasnÆt possible to establish the relationship between microvessel density and the clinical or histological variables studied.

Micrometastasis and recurrent neck node in supraomohyoid neck dissection field.

OBJECTIVES: Supraomohyoid neck dissection (SOHND) is one of the treatment for clinically negative neck disease in carcinoma of the oral cavity when primary is treated with surgery. Neck tumor recurrence in these patients who were treated by SOHND with and without post-operative radiotherapy was evaluated. MATERIAL AND METHOD: Forty-four patients with squamous cell carcinoma of the oral cavity aged between 33-78 years was studied Every case had clinically negative neck and was treated with SOHND. RESULTS: There were 53 supraomohyoid neck dissections. The overall recurrence rate was 11.3% (6/53). The duration of recurrence ranged from six to nine months and was seen in five of pathologically negative neck and one in pathologically positive neck. Five of six of the recurrence cases were in the field of SOHND without post-operative radiotherapy. Histopathological review with immunohistochemistry study of all recurrent cases that was previously reported as negative by H&E stain showed no micrometastasis. The 5-yr survival of neck node metastasis was 64% versus 82% of these with no lymph node metastasis which showed no statistically significant difference. CONCLUSION: The SOHND was useful for treating clinical negative neck of oral cancer with high percentage of occult lymph node. The pathological report influenced the adjuvant treatment. Micrometastasis and other indicators for this pathologically negative neck is still await further study to improve survival of this particular group of patients.

Clinical and epidemiological features of oral cancer in a medical school teaching hospital from 1994 to 2002: increasing incidence in women, predominance of advanced local disease, and low incidence of neck metastases

OBJETIVO: Caracterizar epidemiológica e clinicamente a população atendida por câncer de boca em hospital-escola de atenção terciária e quaternária e verificar variações em relação a outras casuísticas e períodos. MÉTODO: Procedeu-se à revisão dos prontuários dos operados por câncer oral de 1994 a 2002. As características clínicas e epidemiológicas foram colocadas em planilhas e analisadas. RESULTADOS: Foram identificados 374 portadores de câncer da boca que foram submetidos a 406 operações. A idade dos doentes variou de 14 a 94 anos (média = 57,4 anos). Duzentos e cinqüenta e cinco eram do gênero masculino (68,2%). Duzentos e noventa e cinco entre 366 doentes eram caucasianos (80,6%). A maioria era portadora de tumores da língua e/ou do soalho da boca (194 entre 349 doentes; 55,6%), e 71 (20,3%) tinham tumores dos lábios. O carcinoma epidermóide foi encontrado em 90,3% e carcinomas glandulares em 4%. Os tumores T4 estavam presentes em 39,6% dos doentes; 15,2% tinham lesões Tis ou T1. Quase 62% dos pacientes não tinham metástases cervicais. A incidência relativa em jovens (com até 40 anos de idade) atingiu 8,6%. CONCLUSÃO: Apesar dos achados freqüentemente referidos na literatura terem se confirmado (como o predomínio de lesões avançadas localmente), a maioria dos doentes não apresentava metástases cervicais. Acima do observado em outras casuísticas, os 31,8% de mulheres na presente casuística indica a preocupante e crescente incidência no gênero feminino.

Renal cell carcinoma presenting as a cervical mass

The authors report a case of a 60-year-old woman presenting with a renal cell carcinoma in which the first sign leading to its diagnosis was a cervical metastasis, an uncommon site of distant disease in renal neoplasms. The patient had an 18-month history of a progressively enlarging cervical mass at the anterior aspect of the neck. After laboratory and radiological evaluation, the cervical mass was excised, and the microscopic and immunohistochemical patterns suggested the possibility of a metastatic renal cell carcinoma. Computerized tomography of the abdomen showed a solid, 4 cm left renal mass. A radical left nephrectomy was performed, and the histology confirmed the suspected diagnosis. The patient received immunotherapy, and in a follow-up period of 9 months, there was no evidence of recurrent disease. It seems that head and neck metastasis of renal cell carcinoma should preferentially be treated with surgical excision because of the associated morbidity and quality-of-life issues.

A Case of Primary Hepatic Leiomyosarcoma Presenting with Multiple Subcutaneous Scalp Mass / 대한소화기학회지

Leiomyosarcoma is an uncommon tumor which arises from various sites including uterus, stomach, retroperitoneum, superficial soft tissues, bladder, kidney, and lung. Primary hepatic leiomyosarcoma is a very rare tumor and fewer than 70 cases of primary hepatic leiomyosarcoma have been reported since the first publication in Japan. And there was only one case report of cutaneous metastasis from hepatic leiomyosarcoma. We recently experienced a case of primary hepatic leiomyosarcoma presenting as subcutaneous palpable mass. Herein we report this case with a review of literatures.

Melanoma ganglionic metastasis 30 years after treatment the primary tumor: a case report

The recurrence of melanoma in patients is well-documented, and is dependent on a number of factors. We report a case in which a patient had a case of galglionar metastasis in the neck after a 30-year disease-free interval following primary treatment.
