ABSTRACT
Patients with systemic lupus erythematosus have a higher incidence of neoplasms associated with human papillomavirus infections, such as those that affect the vulva, the vagina, and the cervix; however, little is known about the frequency of anal cancer among these patients. Although there are recommendations for screening for this cancer in immunosuppressed individuals, it is possible that this procedure is not strictly followed. We describe the case of a 47-year-old woman with systemic lupus erythematosus who was treated with immunosuppressants and developed advanced anal squamous cell carcinoma after adequate treatment and healing of a high-grade cervical squamous intraepithelial lesion. Five years after the completion of the anal cancer treatment, the patient presented with cystic hepatic lesions that were histopathologically confirmed to be metastatic squamous cell carcinoma. This report aimed to highlight the need for anal cancer screening in patients with lupus, particularly if there was a history of cervical cytopathological alterations. (AU)
Resumo Pacientes com lúpus eritematoso sistêmico apresentam maior incidência de neoplasias associadas a infecções por HPV, como aquelas que acometem a vulva, a vagina e o colo do útero, mas pouco se sabe sobre a frequência de câncer anal entre essas pacientes. Embora existam recomendações para o rastreamento desse câncer em indivíduos imunossuprimidos, é possível que esse procedimento não esteja sendo rigorosamente seguido. Descrevemos uma mulher de 47 anos com lúpus eritematoso sistêmico, tratada com imunossupressores, que desenvolveu um carcinoma escamocelular anal avançado após tratamento adequado e cicatrização de lesão intraepitelial escamosa cervical de alto grau. Cinco anos após o término do tratamento do câncer anal, a paciente apresentou lesões císticas hepáticas cujo resultado citopatológico confirmou ser carcinoma escamocelular metastático. O presente relato teve como objetivo chamar atenção para a necessidade do rastreamento do câncer anal em pacientes com lúpus, principalmente se houver história prévia de alterações citopatológicas cervicais.

Introdução: A prevalência do câncer de pulmão tem aumentado cerca de 2% ao ano e é considerado um problema de saúde pública mundial, sendo a principal causa de morte por câncer entre homens e mulheres. O Câncer de Pulmão de Células Não Pequenas (CPCNP) representa 85-90% dos cânceres de pulmão. A detecção do rearranjo do gene ROS1, considerada um importante fator preditivo para direcionamento terapêutico, constitui uma etapa crítica no tratamento de CPCNP. Objetivo: Avaliar a prevalência do rearranjo do gene ROS1 em pacientes portadores de CPCNP não escamoso, sem mutação de EGFR ou rearranjo de ALK, diagnosticados na Região da Foz do Rio Itajaí, Estado de Santa Catarina, Brasil, no período de 02/01/2019 a 27/07/2020. Materiais e Métodos: Estudo observacional, retrospectivo e prospectivo, descrito e analítico com 95 pacientes que possuíam material de biópsia suficiente para a realização de novas análises e que não apresentavam mutação de EGFR ou rearranjo de ALK. Os pacientes com imuno-histoquímica positiva para a proteína ROS1 foram testados pelo método de FISH, utilizando-se uma sonda de DNA do tipo break-apart para o gene ROS1. Foi realizada uma análise descritiva da amostra, e os resultados foram apresentados em números absolutos e porcentagens, representados por tabelas. O teste de qui-quadrado (χ2) foi empregado para comparação das frequências entre os grupos analisados. Resultados: 52,6% foram pacientes do sexo masculino; a idade mediana foi de 64 anos; 54,7% declararam-se tabagistas; 40,0% apresentavam doença estágio IV; 29,5% apresentaram tumores com alta expressão de PD-L1. Quanto a expressão de ROS1 por imuno-histoquímica: 89,5% foram identificados como ROS1+ em 0% das células tumorais, 4,2% como ROS1+ em <70% das células, e 6,3% como ROS1+ em ≥70% das células do tumor; portanto, 10,5% apresentaram resultados positivos para expressão de ROS1. Estes pacientes foram submetidos à análise de rearranjo de ROS1 pelo método de FISH e 7 (7,4%) apresentaram resultados positivos. Conclusão: Na população estudada, a análise pelo método de FISH mostrou uma prevalência de 7,4% para rearranjos do gene ROS1
Introduction: Lung cancer prevalence has been increasing at rate of 2% per year and is considered a major public health concern worldwide, being the main cause of cancer death among women and men. Non-small cell lung cancer (NSCLC) represents 85-90% of total lung cancer. Detecting the rearrangement of the ROS1 gene is critical to the treatment of NSCLC. Objective: To assess the prevalence of the ROS1 gene rearrangement in patients diagnosed with non-squamous NSCLC patients diagnosed between January 2019 to July 2020 at Foz do Rio Itajaí, in the state of Santa Catarina, Brazil. Materials and Methods: This is a retrospective and prospective observational study Ninety-five NSCLC whose tumors were negative for EGFR mutation and ALK rearrangement and who had enough tumor tissue to carry out additional molecular analysis. Patients whose tumors were positive for ROS1 by immune-histochemistry were tested using by FISH using a break-apart DNA probe (Abbot Molecular) for the ROS1 gene. A descriptive analysis was performed and results were presented as absolute frequencies and percentages and depicted in charts. Frequencies were compared with the chi-squared test (χ2). Results: 52,6% were male, mean and median age were 65,10 and 64 years, respectively. 54,7% self-declared as smokers; 40,0% had stage IV disease; 29,5% had tumours with high expression of PD-L1. Regarding the expression of ROS1 by immunohistochemistry: 89,5% were identified as ROS1+ in 0% of cells, 4,2% as ROS1+ in <70% of cells, and 6,3% as ROS1+ in ≥70% of the cells; therefore, 10,5% displayed positive results for the expression of ROS1+. These tumors were subjected to the analysis of ROS1 rearrangement by FISH and 7 (7,4%) were positive. Conclusion: We observed 7,4% prevalence for ROS1 gene rearrangements in this pre-selected population

Adenosquamous cell carcinoma of tonsil is a rare lesion of head and neck and is often misdiagnosed as squamous cell carcinoma. It has a very aggressive clinical pattern. We encountered a patient with an adenosquamous cell carcinoma of tonsil and performed various treatment modalities including surgical resection, radiation therapy, chemotherapy but the patient expired two years after the first diagnosis. Such case has never been reported earlier in Korea. Herein, we present this rare case with a review of related literature.

IgG4-related disease is a systemic inflammatory disease and is known as IgG4-related lung disease (IgG4-RLD) when it involves the respiratory system. Primary lung cancer arising from a background of IgG4-RLD is very rare. Herein, we report a case of adenosquamous carcinoma arising from the background of IgG4-RLD and presenting as an interstitial lung disease pattern. A 66-year-old man underwent lobectomy under the impression of primary lung cancer. Grossly, the mass was ill-defined and gray-tan colored, and the background lung was fibrotic. Microscopically, tumor cells showed both squamous and glandular differentiation. Dense lymphoplasmacytic infiltration with fibrosis and obliterative phlebitis were seen in the background lung. IgG4 immunohistochemical stain showed diffuse positivity in infiltrating plasma cells. Primary lung adenosquamous carcinoma has not been reported in a background of IgG4-RLD. Due to the rarity of IgG4-RLD, physicians must follow patients with IgG4-RLD over long periods of time to accurately predict the risk of lung cancer.

RESUMO Objetivo: analisar a expressão do Fator de Crescimento do Endotélio Vascular (VEGF), seu receptor (VEGFR-2), idade e tipo histológico de carcinomas avançados de colo uterino com relação à resposta clínica à quimioterapia neoadjuvante. Métodos: foram incluídas 40 pacientes com diagnóstico de carcinoma de colo uterino (IB2 e IVA), com biópsias prévias ao tratamento. Todas as pacientes foram submetidas à quimioterapia neoadjuvante e avaliadas quanto à resposta clínica e à expressão do VEGF. Considerou-se boa resposta clínica uma regressão tumoral total ou maior do que 50%. Resultados: em relação à resposta à quimioterapia, 18 pacientes (45%) apresentaram boa resposta e 22 (55%), má resposta. Quanto à expressão do VEGF, em 16 pacientes foi considerada positiva e em 24, negativa. Quando os casos foram analisados separadamente em relação à resposta à quimioterapia, somente a expressão positiva de VEGF foi associada à boa resposta clínica (p=0,0157). Conclusão: a expressão de VEGF mostrou ser isoladamente, um importante marcador de boa resposta ao tratamento quimioterápico neoadjuvante das pacientes com carcinoma avançado de colo uterino.
ABSTRACT Objective: to analyze the expression of Vascular Endothelial Growth Factor (VEGF), its receptor (VEGFR-2), age and histological type of advanced cervical carcinomas with respect to the clinical response to neoadjuvant chemotherapy. Methods: we studied 40 patients with cervical carcinoma (IB2 and IVA) diagnosed by biopsies prior to treatment. All patients underwent neoadjuvant chemotherapy and evaluation for clinical response and expression of VEGF. We considered a tumor regression greater than 50% as a good clinical response. Results: eighteen patients (45%) had good response to chemotherapy, and 22 (55%), poor response. VEGF expression was positive in 16 patients and negative in 24. When analyzed separately for response to chemotherapy, only the positive expression of VEGF was associated with good clinical response (p=0.0157). Conclusion: VEGF expression alone was an important marker of good response to neoadjuvant chemotherapy in patients with advanced carcinoma of the cervix.

@#A 43-year-old man presented with two-month history of fatigue, weakness, paleness, rectal bleeding, sweating, and weight loss of 10 kg in the past one month. A complete blood count revealed anaemia. The patient underwent a right hemicolectomy. The microscopic examination revealed an adenosquamous carcinoma associated with a mucinous adenocarcinoma in a patient with microsatellite instability due to loss of MLH1 and PMS2 expression and retention of MSH2 and MSH6 expression in both the squamous and glandular components. We also observed an atypical immunohistochemical phenotype in the adenocarcinoma component showing CK7 expression and reduced CK20 and CDX2 expression.

OBJECTIVE@#To analyze the clinical features and prognosis of cervical adenocarcinoma (AC) and adenosquamous carcinoma of cervix (ASC).@*METHODS@#The clinical data of 237 patients, including 201 cases of AC and 36 cases of ASC (FIGO stage ⅠB1-ⅡA), who underwent surgery in Qilu Hospital between September 2007 and September 2016 were reviewed. Clinical features of two groups were compared, and Kaplan-Meier survival analysis was performed to evaluate the prognosis.@*RESULTS@#A larger proportion of ASC patients had lymphovascular space invasion compared with AC patients (0.05). The 5-year overall survival rates of AC and ASC groups were 79.4% and 78.3%, and the 5-year recurrence-free survival rates were 77.4% and 73.0%. Among patients received concurrent chemoradiotherapy, the 5-year overall survival rates were 71.0% and 61.4%, and the 5-year recurrence-free survival rates were 68.8% abd 61.1%, respectively. No significant differences were observed in 5-year overall survival rates and recurrence-free survival rates between AC and ASC patients (all >0.05).@*CONCLUSIONS@#Lymphovascular space invasion was more likely to occur in patients with ASC, but there was no significant difference in the prognosis between AC and ASC patients.

BACKGROUND@#The incidence and the mortality of lung cancer rank first among all malignant tumors and it seriously affects human health. The common types of non-small cell lung cancer (NSCLC) are adenocarcinoma and squamous carcinoma with clinical research and more attention, while adenosquamous carcinoma is a rare pathological subtype of lung cancer, which clinical features and prognostic factors are not yet fully understood. The purpose of this study is to analyze the clinical features and prognosis of lung adenosquamous carcinoma, and construct a nomogram to predict the patients' prognosis.@*METHODS@#We obtained the data of adenosquamous carcinoma patients diagnosed between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database of the United States, and compared their clinical features and prognosis with those of lung adenocarcinoma and lung squamous cell carcinoma patients in the same period. Then we used univariate and multivariate analyses to explore the independent prognostic factors of adenosquamous carcinoma. Finally, we constructed and validated a nomogram to visually predict the outcomes of lung adenosquamous carcinoma.@*RESULTS@#1,453 patients with lung adenosquamous carcinoma were finally included. Compared with patients with lung adenocarcinoma and lung squamous cell carcinoma, the distributions of lung adenocarcinoma patients in most of the variables were medium between lung adenocarcinoma and squamous cell carcinoma. The prognosis of adenosquamous carcinoma was better than that of lung squamous cell carcinoma, but worse than that of lung adenocarcinoma. Multivariate analysis showed that age, differentiation, tumor-node-metastasis (TNM), surgery, and chemotherapy were independent prognostic factors (all P were less than 0.001). We constructed a nomogram with a C-index of 0.783 (0.767-0.799). The distinction test and consistency test showed that the nomogram could predict the patient's prognosis effectively.@*CONCLUSIONS@#Lung adenosquamous carcinoma has unique clinical, pathological, and prognostic characteristics. Age, differentiation, T, N, M, surgery, and chemotherapy status are independent predictors of prognosis in patients with adenosquamous carcinoma. Our nomogram can efficiently predict the prognosis of patients.

Large cell neuroendocrine carcinoma (LCNEC) of the gallbladder is extremely rare and usually combined with other type of malignancy, mostly adenocarcinoma. We report an unusual case of combined adenosquamous carcinoma and LCNEC of the gallbladder in a 54-year-old woman. A radical cholecystectomy specimen revealed a 4.3×4.0 cm polypoid mass in the fundus with infiltration of adjacent liver parenchyma. Microscopically, the tumor consisted of two distinct components. Adenosquamous carcinoma was predominant and abrupt transition from adenocarcinoma to squamous cell carcinoma was observed. LCNEC showed round cells with large, vesicular nuclei, abundant mitotic figures, and occasional pseudorosette formation. The patient received adjuvant chemotherapy. However, multiple liver metastases were identified at 3-month follow-up. Metastatic nodules were composed of LCNEC and squamous cell carcinoma components. Detecting LCNEC component is important in gallbladder cancer, because the tumor may require a different chemotherapy regimen and show early metastasis and poor prognosis.

Pancreatic cancer is the second most common malignancy of the gastrointestinal tract in the US, and adenocarcinoma has been identified as the most common type of pancreatic cancer. Different types of pancreatic cancers have been classified: adenocarcinoma, ductal adenosquamous carcinoma, solid pseudopapillary tumors, endocrine neoplasms, acinar cell carcinoma, squamous cell carcinoma, cystic tumors, primary lymphoma of the pancreas, and metastatic lesions of the pancreas. Adenosquamous carcinoma is extremely rare, behave in a very aggressive way and is responsible for the 1 to 4% of the pancreatic exocrine neoplastic lesions. We describe the case of an 82-years-old African American female, presenting to our institution with quantifiable weight loss (12 kg in 3 months), jaundice and abdominal pain. On admission, laboratory tests were obtained: total bilirubin: 11.07 mg/dl with a direct fraction of 10.32 mg/dl. Cross-sectional abdominal CT scan with contrast, showed a lesion localized in the pancreatic head (hypodense on T1, measuring 3.5 x 3.5 x 2.5 cm), with vascular invasion of the portal vein. EUS showed a solid, hypoechoic, not well-defined lesion (measuring 3.98 x 3.80 cm), localized between the head and neck of the pancreas. EUS-FNA was performed with a 22G needle using the fanning technique. The cytological specimens demonstrated components of both squamous carcinoma and adenocarcinoma. The patient underwent ERCP procedure, and biliary drainage was performed with an entirely covered metallic stent placement. After a month from the procedures, the patient died due to the severity of the disease. Endoscopic ultrasound has proven to be the best method to diagnose solid pancreatic lesions, including rare and aggressive type of tumors like primary adenosquamous cell carcinoma that we described in this very interesting case report
El cáncer de páncreas es la segunda neoplasia maligna más común del tracto gastrointestinal en los EE.UU. y el adenocarcinoma ha sido identificado como el tipo más común de cáncer de páncreas. Se han clasificado diferentes tipos de cáncer de páncreas: adenocarcinoma, carcinoma adenoescamoso ductal, tumores pseudopapilares sólidos, neoplasias endocrinas, carcinoma de células acinares, carcinoma de células escamosas, tumores quísticos, linfoma primario del páncreas y lesiones metastásicas del páncreas. El carcinoma adenoescamoso es extremadamente raro y se comporta de manera muy agresiva, es responsable del 1 al 4% de las lesiones pancreáticas exocrinas neoplásicas. Presentamos el caso de una mujer afroamericana de 82 años de edad, que fue admitida a nuestra institución con pérdida de peso cuantificable (12 kg en 3 meses), ictericia y dolor abdominal. Al momento de la admisión, se obtuvieron pruebas de laboratorio: bilirrubina total: 11,07 mg/dl con una fracción directa de 10,32 mg/dl. La tomografía computarizada abdominal transversal con contraste mostró una lesión localizada en la cabeza pancreática (hipodensa en T1, 5 x 3,5 x 2,5 cm) con invasión vascular de la vena porta. El ultrasonido endoscópico mostró una lesión sólida, hipoecoica, no bien definida de 3,98 x 3,80 cm, localizada entre la cabeza y el cuello del páncreas. La biopsia por aspiración con aguja fina guiada por ultrasonido endoscópico se realizó con una aguja 22G utilizando la técnica de ventilación (Fanning). Los especímenes citológicos demostraron componentes de carcinoma escamoso y adenocarcinoma. El paciente se sometió a CPRE y el drenaje biliar se realizó con una prótesis metálica completamente cubierta. Después de un mes de los procedimientos, el paciente falleció debido a la gravedad de la enfermedad. El ultrasonido endoscópico ha demostrado ser el mejor método para diagnosticar lesiones pancreáticas sólidas, incluyendo tumores raros y agresivos como el carcinoma primario de células adenoescamosas que describimos en este interesante relato de caso

OBJECTIVE: To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. METHODS: The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. RESULTS: The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). CONCLUSION: Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC.

The aim of this study was to explore the correlation of ezrin and galectin-3 expressions with prognosis in cervical cancer. The immunohistochemical method was applied to detect ezrin and galectin-3 expressions in normal cervix tissues (n=30), cervicitis tissues (n=28), cervical intraepithelial neoplasia (CIN) tissues (classified as I-III, n=89), and cervical carcinoma tissues (n=84). Follow-up was conducted for 5 to 78 months to analyze the correlation of protein expressions with prognosis. Ezrin and galectin-3 expressions in cervical cancer were significantly higher than in normal cervix, cervicitis and CIN (all P<0.05), and expressions in CIN were significantly higher than in normal cervix and cervicitis (both P<0.05). The expressions of ezrin and galectin-3 were both related with histological grade, deep myometrial invasion and lymph node metastasis (all P<0.05). Spearman analysis showed that ezrin expression was positively correlated with galectin-3 expression in cervical cancer (r=0.355, P<0.05). The survival rate of patients with high expressions of ezrin and galectin-3 was significantly lower than those with low expressions of proteins (both P<0.05). The expressions of ezrin and galectin-3, histological grade, depth of stromal invasion, and lymph node metastasis are risk factors affecting the survival rate of patients with cervical cancer. The expressions of ezrin and galectin-3 were correlated with the development of cervical cancer, and overexpressions of those proteins were indicative of poor prognosis in patients with cervical cancer.

Abstract Adenosquamous carcinoma is an aggressive variant of squamous cell carcinoma. This report describes a case of adenosquamous carcinoma with clinical features of a benign lesion and discusses the differential diagnoses, especially regarding histopathological and immunohistochemical analyses. A 45-year-old male was referred to our outpatient clinic complaining about a rapid-growing enlargement in hard palate. Clinical examination revealed an erythematous and pedunculated nodule with lobulated non-ulcerated surface. Excisional biopsy was performed following clinical diagnosis of pyogenic granuloma. Histologically, the specimen consisted of areas characterizing both well-differentiated squamous cell carcinoma and true adenocarcinoma. After a broad list of immunohistochemical markers was evaluated (AE1/AE3, CEA, CK5, CK7, CK8/18, p53, p63 and Ki67), the diagnosis of adenosquamous carcinoma was rendered and the patient referred to complementary surgery. Adenosquamous carcinoma represents a challenge in diagnostic routine due to its rarity, diverse range of clinical presentations and histological features. Furthermore, classical clinical benign features may be present in malignant lesions; hence the submission of every surgical specimen to histological analysis is mandatory to provide the patient the adequate treatment.
Resumo O carcinoma adenoescamoso é uma variante agressiva do carcinoma de células escamosas. Este relato descreve um caso de carcinoma adenoescamoso que apresenta características clínicas de uma lesão benigna e discute o diagnóstico diferencial, especialmente em relação à análise histopatológica e imuno-histoquímica. Um homem de 45 anos foi encaminhado ao nosso serviço queixando-se um aumento de volume de rápido crescimento no palato duro. O exame clínico revelou um nódulo eritematoso e pedunculado com superfície lobulada não ulcerada. Foi realizada biópsia excisional seguindo a hipótese clínica de granuloma piogênico. Histologicamente o fragmento consistia em áreas de carcinoma de células escamosas bem diferenciado e áreas de adenocarcinoma verdadeiro. Após a avaliação de uma ampla lista de marcadores imuno-histoquímicos (AE1/AE3, CEA, CK5, CK7, CK8/18, p53, p63 e Ki67), o diagnóstico de carcinoma adenoescamoso foi atribuído e o paciente foi encaminhado à cirurgia complementar. O carcinoma adenoescamoso representa um desafio na rotina de diagnóstico, devido à sua raridade, diversificada gama de apresentações clínicas e características histológicas. Além disso, características clínicas benignas podem estar presentes em lesões malignas, por isto a submissão de todas as peças cirúrgicas à análise histológica é obrigatória para fornecer ao paciente o tratamento adequado.

A rectal carcinoma, including primary an adenosquamous and a squamous cell carcinoma (SCC), is a very rare disease, accounting for 0.025% to 0.20% of all large-bowel malignant tumors. Because SCCs have a higher mortality than adenosquamous carcinomas, determining whether the primary rectal cancer exhibits an adenomatous component or a squamous component is important. While differentiating between these 2 components, especially in poorly differentiated rectal cancer, is difficult, specific immunohistochemical stains enable accurate diagnoses. Here, we report the use of immunohistochemical stains to distinguish between the adenomatous and the squamous components in 2 patients with low rectal cancer, a 58-year-old man and a 73-year-old woman, who were initially diagnosed using the histopathologic results for a poorly differentiated carcinoma. These data suggest that using these immunohistochemical stains will help to accurately diagnose the type of rectal cancer, especially for poorly differentiated carcinomas, and will provide important information to determine the proper treatment for the patient.

We experienced a case of carcinoma ex pleomorphic adenoma arising in the submandibular gland of a 47-year-old male patient. The patient underwent submandibular gland ressection and supraomohyoid neck dissection. Histologic examination revealed that the malignant component of carcinoma ex pleomorphic adenoma was adenosquamous carcinoma. The patient refused postoperative radiation therapy and tumor recurred at the neck and lung about 18 month later. Modified radical neck dissection was carried out, and additional postoperative radiotherapy and palliative chemotherapy were initiated. To the best of our knowledge, this is the first case of carcinoma ex pleomorphic adenoma, of which the malignant component is adenosquamous carcinoma in the submandibular gland. Therefore the authors report this rare case with a literature review.

Adenosquamous carcinoma of the liver is a rare variant of cholangiocarcinoma. It is known to be a highly aggressive tumor with a poor prognosis, but its pathogenesis remains unclear owing to limited data in the literature. We report a case of 56-year-old woman who presented with a 1-week history of epigastric pain. Magnetic resonance imaging revealed a 6.5-cm ill-defined mass with low signal intensity in the left lobe of the liver, which was suspicious of cholangiocarcinoma. The patient underwent left hemihepatectomy. Microscopically, the tumor consisted of malignant glandular and squamous components and staged as pT2aN1. Despite postoperative chemoradiation, the patient had recurrence 8 months after surgery.

El carcinoma adenoescamoso primario de la vesícula biliar es una variante poco conocida e infrecuente de este tipo de neoplasias, cuya etiología y comportamiento siguen constituyendo un enigma. Se trata de una paciente de 45 años de edad con un carcinoma adenoescamoso primario de vesícula biliar; se presenta este caso por ser un reto diagnóstico debido a lo poco que se conoce sobre esta entidad, la cual es considerada más agresiva y de peor pronóstico que el adenocarcinoma en su presentación clásica.
Adenosquamous carcinoma of the gallbladder is a little-known and infrequent variant of carcinoma, and its etiology and behavior are not completely known. In this review we present a patient of 45 years with a primary adenosquamous carcinoma of the gallbladder, a case that is reported for being a diagnostic challenge for an uncommon entity, which is considered more aggressive and of worse prognosis than the adenocarcinoma in its classical presentation.
