ABSTRACT
Se realizó un estudio descriptivo, retrospectivo y transversal de 87 pacientes con tumores cutáneos no melanoma, atendidos en el Servicio de Dermatología del Hospital Clinicoquirúrgico Docente Dr Joaquín Castillo Duany de Santiago de Cuba, desde enero de 2012 hasta igual mes de 2014 con el objetivo de caracterizarles según variables clínicas y epidemiológicas de interés para la investigación. La información se recogió de las historias clínicas y de los informes de anatomía patológica. Como medidas de resumen para variables cuantitativas y cualitativas se utilizaron la media, la frecuencia absoluta y la relativa. En la serie predominaron el carcinoma basocelular (60,0 por ciento), el sexo masculino, los pacientes de piel blanca y los mayores de 50 años de edad; asimismo, la cabeza resultó ser la región topográfica más afectada y la forma clínica nodular la más frecuente. Según la ocupación, los agricultores y los albañiles estuvieron mayormente relacionados con este tipo de cáncer de piel.
A descriptive, retrospective and cross-sectional study of 87 patients with non melanoma cutaneous tumors, assisted in the Dermatology Service of Dr Joaquín Castillo Duany Clinical Surgical Hospital in Santiago de Cuba was carried out from January, 2012 to the same month of 2014 with the objective of characterizing them according to clinical and epidemiological variables of interest for the investigation. The information was collected from the medical records and from the pathology reports. For quantitative and qualitative variables, means, absolute frequency and the relative frequency were used as summary measures. In the series, the basocelular carcinoma (60,0 percent), male sex, the white skin patients and those older than 50 years prevailed; also, the head turned to be the most affected topographical region and the most frequent nodular clinical type. According to the occupation, farmers and bricklayers were mostly related to this type of skin cancer.

El tumor odontogénico epitelial calcificante o tumor de Pindborg es una neoplasia odontogénica benigna y poco frecuente que afecta predominantemente la mandíbula. El objetivo de este trabajo fue reportar y discutir un caso clínico de una mujer de 65 años de edad que presentaba un tumor de Pindborg en la zona de sínfisis mentoniana. El diagnóstico presuntivo se realizó según los hallazgos clínicos y radiográficos. Se efectuó una biopsia incisional que confirmó el diagnóstico. El tratamiento se basó en la resección completa de la masa tumoral con legrado óseo quirúrgico periférico. Para la prevención de la fractura patológica, se colocó una placa de reconstrucción y relleno óseo en la lodge posquirúrgica. A pesar del porcentaje de recidiva en casos reportados en la literatura, el tratamiento fue conservador y el control a distancia después de 6 años fue favorable (AU)
The calcifying epithelial odontogenic tumor (CEOT) or Pindborg tumor, is a rare benign but locally aggressive odontogenic neoplasm that affects the jaw. We report and discuss a case of a 65-year-old woman who presented a Pindborg tumor located in the mandibular symphysis region. The presumptive diagnosis was carried out by means of clinical and radiologic findings. The diagnosis was confirmed by the histological examination. Then, a resection of the entire mass was done, with osseous curettage. Reconstruction was achieved using a reconstruction plate system and bone void filler. Because of the risk of recurrence, the patient was followed closely. At the last follow-up examination 6 years after treatment the panoramic radiograph demonstrated that the cavity was almost completely ossified without any sign of CEOT recurrence (AU)

Undifferentiated carcinoma of the pancreas is a malignant neoplasm that is uncommon among domestic species, especially cockatiels (Nymphicus hollandicus), one of the most popular birds kept as a pet throughout the world. The aim of this study was to describe the occurrence of an undifferentiated carcinoma in the pancreas of a cockatiel. A bird, an adult male that died naturally with swelling in the abdominal region, was referred to necropsy. Macroscopic examination showed poor body condition, the coelomic cavity filled with liquid and a white mass attached to the pancreas and other smaller masses attached to the duodenum. Tissue samples and organs were harvested and fixed in 10% buffered formalin, then routinely processed for histopathology and stained with hematoxylin and eosin. Microscopic analysis demonstrated an epithelial neoplasia with a predominantly solid pattern, lymphatic invasion and involvement of the intestinal serous membrane. These findings indicate the occurrence of an undifferentiated pancreatic carcinoma in a cockatiel that was diagnosed by histopathology.(AU)
O carcinoma indiferenciado de pâncreas é uma neoplasia maligna, incomum entre as espécies domésticas, especialmente em calopsitas (Nymphicus hollandicus), uma das aves mais populares como animal de companhia no mundo. O objetivo deste trabalho foi descrever a ocorrência de carcinoma indiferenciado de pâncreas em Nymphicus hollandicus. Uma ave, macho adulto, com morte natural e com aumento de volume em região abdominal, foi encaminhada para necropsia. Ao exame macroscópico foram observados mau estado corporal, cavidade celômica repleta de líquido e massa esbranquiçada aderida ao pâncreas e outra menor aderida ao duodeno. Amostras de tecidos e órgãos foram colhidas em formol 10% tamponado, processadas rotineiramente para histopatologia e coradas por hematoxilina e eosina. Na microscopia foi observada neoplasia epitelial com padrão predominantemente sólido, com invasão linfática e implantação na serosa intestinal. Com esses achados, comprovou-se a ocorrência de carcinoma indiferenciado de pâncreas em Nymphicus hollandicus, o qual pode ser diagnosticado por meio de histopatologia.(AU)
