Tratamiento exitoso de un hemangioma de parótida con propranolol / Successful treatment of parotid hemangioma by using propranolol

Los hemangiomas infantiles son los tumores vasculares benignos más frecuentes en la infancia, que ocurren mayormente en los pacientes pretérmino, en un 80 por ciento afectan cabeza y cuello, y en algunos pacientes provocan serias complicaciones para la vida. El hemangioma de parótida es una forma clínica de presentación en la que suele verse un período proliferativo prolongado con lenta involución. Se presenta el caso clínico de un paciente con diagnóstico de hemangioma de parótida con componente superficial y profundo, tratado con propranolol, con excelente respuesta al tratamiento, involución completa clínica e imaginológica del tumor en 10 semanas(AU)

Infantile hemangiomas are the most common benign vascular tumors in childhood that mostly emerge in preterm patients, affect head and neck in 80 percent of cases and cause serious life-threatening complications for some patients. The parotid hemangioma is a clinical form of presentation that may be seen in a prolonged proliferative period with slow regression. This is the clinical case of a patient diagnosed with parotid hemangioma of superficial and deep component. He was treated with propranolol, showed excellent response to treatment, and complete clinical and imaging regression of tumor in a 10-week period(AU)

Parotid gland metastasis of a breast cancer.

Parotid gland metastases from malignant tumors are extremely rare. A 61-year-old woman was diagnosed with an early breast cancer with no expression of oestrogen and progesterone receptors. Five years later the patient presented a tumour in parotid gland. After total parotidectomy, microscopic analysis of the gland demonstrated an invasive duct carcinoma (IDC) with positive expression of oestrogen receptor. The patient was treated with chemotherapy followed by complementary local radiotherapy. Diagnosis of a metastasic tumour in parotid gland poses a challenge. In our case an immunohistochemical study of oestrogen receptor was fundamental to establish a diagnosis.

Linfomas del tubo digestivo y glándulas anexas en pacientes con SIDA: serie de casos / Non-Hodgkins lymphomas of the digestive tract and anexal glands in AIDS patients

Introducción: el linfoma no Hodgkin (LNH) es la segunda neoplasia más frecuente en pacientes con SIDA. Una de las principales características de los LNH asociados con el SIDA es la alta frecuencia de compromiso extranodal, incluyendo el tracto astrointestinal, como manifestación inicial de la neoplasia. Métodos: se analizaron de manera retrospectiva las características epidemiológicas, clínicas, virológicas, inmunológicas e histopatológicas de 8 pacientes con diagnóstico de linfomas del tracto gastrointestinal y glándulas anexas (hígado y parótida) asistidos en la División de VIH- /SIDA del Hospital de Enfermedades Infecciosas F J Muñiz de Buenos Aires, Argentina, entre enero de 1997 y diciembre de 2004. Todos los pacientes fueron evaluados por tomografía computarizada y examen de la médula ósea, además de los exámenes endoscópicosde diagnóstico. Resultados: todos los pacientes fueron varones; 4 eran heterosexuales, 2 homosexuales, uno hemofílico y uno adicto a drogas endovenosas. Tres pacientes presentaron coinfección por el virus de la hepatitis C. La mediana de edad fue de 42 años y la mediana de linfocitos T CD4 + fue de 87 células/uL al momento del diagnóstico de la neoplasia. Ningún paciente recibía TARGA al momento del diagnóstico del linfoma. La incidencia global de linfomas (primarios del sistema nervioso central, no Hodgkin sistémicos y de Hodgkin) durante el período de estudio fue de 2,9% (54 casos); 17 pacientes (32%) tuvieron diagnóstico de LNH sistémicos; 10 (58,8%) de ellos tuvieron presentación extranodal al momento del inicio de las mani manifestaciones clínicas y 8 (80%) comprometieron el tubo digestivo y las glándulas anexas (parótida, cavum, esófago, estómago, duodeno, colon derecho en 2 casos e hígado en el restante), como LNH primarios, de alto grado y de fenotipo "B". Todos los pacientes presentaronsíntomas "B" al momento del diagnóstico. De acuerdo con los criterios de estadificación de Lugano, 4 se encontraban en el estadio...(AU)

Background: Non-Hodgkins lymphoma (NHL) is the second most common neoplasm among patients with AIDS. One of the major clinical characteristics of AIDS-associated NHL is the high frequency of extranodal involvement, including the gastrointestinaltract, at initial presentation. Methods: From January 1997 to December 2004, 8 cases of NHL of the digestive tract and anexal glands (liver and parotid gland) were observed at the HIV/AIDS division of the Infectious Diseases F J Muñiz Hospital from Buenos Aires,Argentina. All patients were staged by computed tomography scanning and bone marrow examination, in addition to the endoscopic evaluation. Results: All patients were males; 4 were heterosexual, 2 homosexual, and 1 were a hemophilic and an intravenous drug abuser. The median age was 42 years and the median CD4 T cell count was 87 cells/uL at the time of the diagnosis of neoplasm. No patient was receiving highly active antiretroviral therapy (HAART) at lymphoma diagnosis. The global incidence of AIDS-associated lymphomas (central nervous system lymphomas, non-Hodgkin lymphomas and Hodgkin lymphoma) during the time of study was 2,9% (54 cases); 17 patients(32%) had diagnosis of systemic NHL; 10 (58,8%) of them were extranodal at the onset of clinical symptoms and 8 (80%) involvement the digestive tract and anexal glands (parotid gland, cavum, esophagus, stomach, duodenum, the right colon in 2 patients and the liver), as primary NHL of high grade and "B" phenotype. All patients presented "B" symptoms at the time of diagnosis. Primary duodenal lymphoma was the only Burkittlymphoma of this serie and we detected the Epstein-Barr virus genome in the biopsy smears of this tumor and in the hepatic lymphoma. Four patients were treated with systemic chemotherapy with granulocytic growth factor support plus highly active antiretroviral therapy (HAART); 2 of them (cavum and one of the colon) had a prolonged survival with immune reconstitution during 5 and 6...

[Non-Hodgkin's lymphomas of the digestive tract and anexal glands in AIDS patients]. / Linfomas del tubo digestivo y glándulas anexas en pacientes con SIDA. Serie de casos.

BACKGROUND: Non-Hodgkin's lymphoma (NHL) is the second most common neoplasm among patients with AIDS. One of the major clinical characteristics of AIDS-associated NHL is the high frequency of extra-nodal involvement, including the gastrointestinal tract, at initial presentation. METHODS: From January 1997 to December 2004, 8 cases of NHL of the digestive tract and anexal glands (liver and parotid gland) were observed at the HIV/AIDS division of the Infectious Diseases FJ Muñiz Hospital from Buenos Aires, Argentina. All patients were staged by computed tomography scanning and bone marrow examination, in addition to the endoscopic evaluation. RESULTS: All patients were males; 4 were heterosexual, 2 homosexual, and 1 were a hemophilic and an intravenous drug abuser. The median age was 42 years and the median CD4 T cell count was 87 cells/uL at the time of the diagnosis of neoplasm. No patient was receiving highly active antiretroviral therapy (HAART) at lymphoma diagnosis. The global incidence of AIDS-associated lymphomas (central nervous system lymphomas, non-Hodgkin lymphomas and Hodgkin lymphoma) during the time of study was 2,9% (54 cases); 17 patients (32%) had diagnosis of systemic NHL; 10 (58,8%) of them were extranodal at the onset of clinical symptoms and 8 (80%) involvement the digestive tract and anexal glands (parotid gland, cavum, esophagus, stomach, duodenum, the right colon in 2 patients and the liver), as primary NHL of high grade and "B" phenotype. All patients presented "B" symptoms at the time of diagnosis. Primary duodenal lymphoma was the only Burkitt lymphoma of this serie and we detected the Epstein-Barr virus genome in the biopsy smears of this tumor and in the hepatic lymphoma. Four patients were treated with systemic chemotherapy with granulocitic growth factor support plus highly active antiretroviral therapy (HAART); 2 of them (cavum and one of the colon) had a prolonged survival with immune reconstitution during 5 and 6 years, respectively, after the diagnosis. The median survival of the patients, which received HAART plus chemotherapy, was 33 months. The median survival of the others patients was 90 days. CONCLUSION: NHL of the gastrointestinal tract is a severe complication of advanced HIV/AIDS disease. Early diagnosis followed by chemotherapy plus HAART are necessary to improve the prognosis and the survival of these patients.

Endodermal sinus tumor of the parotid gland in a child.

We report a case of a 16-month-old girl with a primary endodermal sinus tumor (EST) of the parotid gland. The girl was admitted to the hospital with a left side cervical tumor with a quick growth (within 3 wk). The tumor was surgically resected. The gross examination showed a 7.0-cm hemorrhagic and fragmentized mass. Diagnosis of an EST was established on the hematoxylin and eosin-stained slides from the resected material. Elevated serum alpha-fetoprotein (AFP) levels were detected and follow-up examinations of the patient did not show ESTs in other locations or other manifestations due to the tumor. The patient received chemotherapy after the surgery and remained alive without evidence of disease at the time of this writing (2 years after the diagnosis). As far as we know, this is the second report in the literature of a parotid gland's EST.
