Variante "no clásica" o "atípica" del síndrome de Stauffer en paciente con carcinoma renal de células claras: reporte de caso / "Non-classical" or "atypical" variant of Stauffer syndrome in a patient with clear cell renal carcinoma: a case report

La manifestación paraneoplásica conocida como síndrome de Stauffer tiene una presentación atípica, caracterizada por ictericia y colestasis intrahepática. Presentamos el caso de un paciente de 53 años de edad, con antecedente de una masa renal derecha en plan de resección quirúrgica programada, con cuadro de evolución de dolor abdominal en hipocondrio derecho e ictericia. A su ingreso se documentó hepatoesplenomegalia, elevación de bilirrubinas a expensas de la directa, y de fosfatasa alcalina junto con elevación de transaminasas. Se descartaron causas obstructivas a nivel de vía biliar intra y extrahepática. No se documentaron metástasis o lesiones focales a nivel de parénquima, ni lesiones de etiología vascular que explicaran el cuadro. También se descartó hepatitis B, C e infección por VIH, por lo cual se consideró un probable síndrome de Stauffer. Fue llevado a nefrectomía intrahospitalaria, con posterior diagnóstico patológico compatible con carcinoma de células claras. Luego del procedimiento se normalizó la bioquímica hepática y se corrigió la ictericia. Es importante reconocer que la afectación hepática en el contexto de neoplasias, no es solo atribuida a metástasis a distancia, sino también a la existencia de síndromes paraneoplásicos como condicionantes.

The paraneoplastic manifestation known as Stauffer syndrome has an atypical presentation, characterized by jaundice and intrahepatic cholestasis. We present the case of a 53-year-old patient, with a history of a right renal mass with a planned surgical resection, who developed abdominal pain in the right upper quadrant and jaundice. Upon admission, hepatosplenomegaly, elevated bilirubin, at the expense of direct bilirubin, alkaline phosphatase and elevated transaminases were documented. Intra- and extrahepatic bile ducts obstruction were ruled out. There were no documented metastases or focal lesions at the level of the parenchyma, or lesions of vascular etiology that could explain the condition. Hepatitis B, C and HIV infection were also ruled out, and a probable Stauffer syndrome was considered. In-hospital nephrectomy was performed, with subsequent pathology compatible with clear cell carcinoma. After the procedure, liver biochemistry was normalized and jaundice was corrected. It is important to recognize that liver involvement in the context of neoplasms is not only attributed to distant metastases but to the existence of paraneoplastic syndromes as determining factors.

Case for diagnosis. Hyperpigmented and excoriated papules and nodules in a diabetic patient

Abstract Reactive perforating collagenosis is a rare perforating dermatosis clinically characterized by intensely pruritic hyperpigmented papules, plaques, and nodules with a central keratotic plug. Histopathology reveals transepidermal elimination of collagen fibers. Its pathophysiology is still under investigation, but the acquired form has been linked to systemic conditions such as diabetes mellitus and chronic kidney disease. However, it has also been described as a paraneoplastic syndrome. The authors present the case of a 65-year-old diabetic patient in which a myeloproliferative neoplasm was suspected.

Oligoartritis, paniculitis y pioderma gangrenoso como manifestaciones de un Linfoma no Hodgkin / Oligoarthritis, panniculitis and pyoderma gangrenosum associated with non-Hodgkin lymphoma: report of one case

An assortment of clinical and laboratory abnormalities may occur as paraneoplastic syndromes in lymphomas. Rheumatological and dermatological manifestations such as paraneoplastic arthritis and pyoderma gangrenosum must be underscored. We report a 28 years old woman who developed pyoderma gangrenosum and two years later presented with arthritis of knees and ankles associated with panniculitis interpreted as erythema induratum that was pathologically confirmed. She developed a reactivation of pyoderma gangrenosum, that was refractory to treatment. Complementary studies showed a pulmonary nodule and a right paravertebral mass with involvement of the psoas muscle. Biopsies of both masses and a new pathological skin study demonstrated a large B-cell non-Hodgkin's lymphoma.

Síndrome vascular acral secundária à neoplasia de pâncreas. Relato de caso e revisão de literatura / Acral vascular syndrome secondary to pancreatic cancer: case report and literature review

Paciente do sexo feminino, de 65 anos, foi admitida em nossa instituição com síndrome do dedo azul. Durante a investigação diagnóstica para as principais etiologias possíveis, foi evidenciado adenocarcinoma de cabeça de pâncreas, tendo sido elaborada associação como manifestação paraneoplásica. A investigação da etiologia da síndrome do dedo azul é de suma importância para a conduta terapêutica adequada, já que as causas podem ter evolução extremamente grave na ausência de intervenção, como é o caso dos pacientes que apresentam tal síndrome secundária à neoplasias.(AU)

A 65-year-old female patient was admitted to our institution with the blue toe syndrome. During the diagnostic investigation for possible etiologies, pancreatic head carcinoma was evidenced, and an association as a paraneoplastic manifestation was established. The investigation of the etiology of the blue toe syndrome is very important for the proper treatment, since the causes may have extremely serious development in the absence of intervention, as it is the case of patients with this syndrome secondary to cancer.(AU)

The coexistence of hypercalcemia and hypoglycemia in a patient with a renal tumor and B cell lymphoma

SUMMARY Paraneoplastic syndromes are a heterogeneous group of malignant diseases caused by events which involve endocrine, immune and metabolic aspects and whose symptoms vary according to the substance produced and the primary tumor. Hypercalcemia is a frequent complication in cancer patients. Prognosis of cancer patients with hypercalcemia is usually poor. A factor called parathyroid hormone related peptide, whose actions are similar to those of the parathyroid hormone, is thought to be the most common cause of malignancy associated hypercalcemia. Non-islet hypoglycemic cell tumor consists of a rare syndrome characterized by the presence of a solid tumor and severe fasting hypoglycemia determined by an insulin-independent pathway. We report a case of a 59-year-old-man with a renal tumor and a T-cell rich large B cell lymphoma who was hospitalized due to severe hypercalcemia and hypoglycemia. The laboratory examination reported hypercalcemia with inhibited PTH and hypoglycemia with inhibited insulin secretion, arriving to the conclusion of tumoral peptide production. He received denosumab and corticoid therapy. The patient died one month later despite initial improvement after medical treatment. While a single paraneoplastic manifestation may be expected in most tumors, the coexistence of two or more of them is rare, except in hepatocellular carcinomas, and it has not yet been described in renal tumors.

Syndrome in question

Abstract: Dermatomyositis is a rare inflammatory disease, autoimmune, with proximal myopathy associated with characteristic dermatological manifestations. In adults, 20-50% of the cases are paraneoplastic manifestation, being mandatory the workup for malignancy Herein we report a case of a woman with classic dermatological presentation of dermatomyositis and newly diagnosed breast cancer. In general, the clinical presentation of paraneoplastic dermatomyositis is more exuberant and manifestations may precede, concur or succeed the diagnosis of neoplasia. The prognosis of cases associated with breast cancer is worse than the idiopathic form. Treatment is based mainly on the resolution of the underlying disease, beyond immunosuppressants.

Dermatomiositis asociada a malignidad / Dermatomyositis associated with malignancy

La dermatomiositis es una enfermedad sistémica que se caracteriza fundamentalmente por la presencia de alteraciones inflamatorias de piel y músculo estriado. En ciertos casos constituye un síndrome paraneoplásico, por lo que su diagnóstico obliga a una exhaustiva búsqueda de la probable asociación con un cáncer. Presentamos tres casos de dermatomiositis asociados a neoplasias, dos mujeres con cáncer ginecológico y un varón con cáncer de estómago. Una de las mujeres también presentaba un síndrome mielodisplásico. En dos casos la dermatomiositis fue posterior al diagnóstico del cáncer y en uno los hallazgos fueron simultáneos.

Dermatomyositis is a systemic disease characterized primarily by the presence of inflammatory skin disorders and striated muscle. In some cases it constitutes a paraneoplastic syndrome, so diagnosis requires a thorough search of the likely association with cancer. We present three cases of dermatomyositis associated with malignancies, two women with gynecologic cancer and a man with stomach cancer. One of the women also had a myelodysplastic syndrome. In two cases dermatomyositis was after the diagnosis of cancer and in one, the findings were simultaneous.

Ataxia e coreia como manifestações de síndrome paraneoplásica / Ataxia and chorea related to paraneoplasic syndrome

Relatamos um caso de ataxia subaguda e coreia em uma paciente adulta. Após extensa investigação, foi estabelecido diagnóstico de neoplasia de mama em associação com síndrome paraneoplásica (SP). SP é rara e pode ser o primeiro sintoma de uma neoplasia oculta. Ataxia é o distúrbio de movimento mais comumente relacionado à SP, no entanto a apresentação de coreia é incomum. A paciente apresentou instalação subaguda de ataxia e coreia. Assim, a SP neurológica deve ser considerada no diagnóstico diferencial de ataxia associada à coreia esporádica a despeito de tal apresentação ser rara.

We report a case of subacute ataxia and chorea in a female adult patient. After an extensive investigation breast cancer was discovered. The final diagnosis was paraneoplastic syndrome (PS). PS is rare and it could be the first symptom of an occult neoplasia. Ataxia is one of the most common movement disorder related to PS although chorea is rare. The patient presented ataxia and chorea, which is not common. Therefore, neurologic PS is important to be considered in the differential diagnosis of sporadic ataxia, as well as chorea.

Dermatomyositis associated with hepatitis B virus-related hepatocellular carcinoma

Dermatomyositis is an idiopathic inflammatory myopathy with typical cutaneous manifestations. It has been proposed that dermatomyositis may be caused by autoimmune responses to viral infections. Previous studies have shown an association between dermatomyositis and malignant tumors such as ovarian cancer, lung cancer, and colorectal cancer. However, a chronic hepatitis B virus (HBV) infection associated with dermatomyositis and hepatocellular carcinoma (HCC) has been very rarely reported. Here, we report a rare case of dermatomyositis coinciding with HBV-associated HCC. A 55-year-old male was confirmed to have HCC and dermatomyositis based on proximal muscle weakness, typical skin manifestations, elevated muscle enzyme levels, and muscle biopsy findings. This case suggests that HCC and/or a chronic HBV infection may be factors in the pathogenesis of dermatomyositis through a paraneoplastic mechanism.

A case of Paraneoplastic Pemphigus associated with Castleman's disease / Um caso de Penfigo Paraneoplastico (PNP) associado a doenca de Castleman

We present a case of PNP associated with Castleman's Disease. We have also reviewed the literature and described the characteristics of the two associated diseases. Gene clonal rearrangement was done to help diagnosis. We used, in addition, stereotactic radiosurgery which, as far as we know, has never before been employed to treat PNP associated with Castleman's Disease. This produced a good response, suggesting that it might be a good alternative treatment for PNP associated with Castleman's Disease when it is too difficult to operate.

Apresentamos um caso de PNP associada à doença de Castleman.Também revisamos a literatura, e referenciamos as características das duas doenças associadas. Um rearranjo genético clonal foi feito para ajudar o diagnóstico. Além disso, usamos a radiocirurgia que até então nunca havia sido utilizada para tratar PNP associada à doença de Castleman. Esta produziu uma boa resposta, sugerindo que pode ser uma boa alternativa para o tratamento de PNP associada com a doença de Castleman quando é muito difícil fazer uma cirugia convencional.

Manifestaciones cutáneas de enfermedades sistémicas / Cutaneous manifestations of systematic diseases

Un gran número de enfermedades sistémicas durante su evolución pueden presentar manifestaciones cutáneas, enocasiones propias de la dolencia, aunque en otras pueden ser el único indicador de la presencia de una enfermedadinterna asintomática, por ello es fundamental su reconocimiento. Su aparición debe alertar al médico sobre el probableinicio de ciertos desórdenes sistémicos, lo que permitirá realizar un diagnóstico precoz, con las implicanciasclínicas y terapéuticas de intervención a corto y largo plazo. El propósito de este trabajo es describir las lesionescutáneas que con mayor frecuencia se asocian a enfermedades internas, lo cual puede ser de gran utilidad para elejercicio de médicos generalistas, internistas y dermatólogos.

Skin signs of systemic diseases occur frequently, and sometimes constitute the first symptoms of an internal disease; furthermore,these manifestations may be the sole expressions of otherwise asymptomatic systemic disorders, so it is neecessary tobecome acquainted with them. Their appearance should alert us of the likely onset of a systemic disorder, which allows anearly diagnosis, with clinical and therapeutic implications both in the short and the long term. We describe the clinicalfeatures of skin lesions observed in several internal diseases which will be useful to general practitioners, internists anddermatologists in the diagnosis of systemic diseases.

Síndromes paraneoplásicas: o que o cirurgião-dentista precisa saber?: [revisão] / Paraneoplastic syndromes: what does the surgeon-dentist needs to know?: [review]

Introdução: o termo paraneoplasia é um conjunto de distúrbios clínicos, bioquímicos, hormonais, neurológicos e/ou hematológicos associados com neoplasias malignas, mas não diretamente relacionados com invasão tumoral primária ou metástase. As síndromes paraneoplásicas podem ser o primeiro sinal de uma malignidade. Revisão de literatura: as síndromes que estão mais comumente relacionadas com a prática odontológica são: de Lambertt-Eaton, de Gardner, de Cowden, de Peutz-Jeghers, de Sjõgren, a neoplasia endócrina múltipla, a neurofibromatose múltipla de Von Recklinghausen, o carcinoma nevóide de células basais, a acantose nigrans e o pênfigo paraneoplásico. Conclusão: o diagnóstico precoce das neoplasias malignas favorece o seu prognóstico e as síndromes paraneoplásicas auxiliam neste diagnóstico. É de suma importância que os Cirurgiões-dentistas conheçam tais síndromes de modo a diagnosticá-las o mais rápido possível e encaminhar os pacientes ao tratamento especializado.

Introduction: the term paraneoplastic is a clinical, biochemical, hormonal, neurological and/or associated disorder with hematologic malignancies, but not directly related to primary tumor invasion and metastasis. Paraneoplatic syndromes may be the first sign of a malignancy. Review of literature: the syndromes that are most commonly related to dentistry are of lambertt-Eaton, Gardner, Cowden disease, Peutz-Jeghers, Sjõgren, multiple endocrine neoplasic, multiple neurofibromatosis of Von Recklinghausen, nevoid basal cell carcinoma, acanthosis nigrans and pemphigus paraneoplastic. Conclusion: early diagnosis of malignant neoplasms favors prognosis and paraneoplastic syndromes assist in diagnosis. It is important that surgeons-dentists know these events in order to diagnose them as soon as possible and refer these patients to specialized treatment.
