ABSTRACT
One of the typical complaints in the pediatric population is umbilical discharge. Among the congenital causes, remnants of omphalomesenteric duct or patent urachus are often detected. On a few occasions, multiple types of ectopic tissue are present. We describe histopathologic findings of two cases reported recently at our center as pediatric umbilical lesions with associated ectopic tissue. Histopathology of the excised mass confirmed the patent omphalomesenteric duct with ectopic gastric, duodenal, and colonic mucosa and pancreatic tissue in two patients with the clinical presentation of umbilical discharge. There were no associated congenital anomalies in these patients. The presence of multiple ectopic gastrointestinal mucosa and pancreas in the umbilical mass is unusual. Herein, we report these cases because of its rarity, multiple ectopic tissues, and reviewing the literature of the reported cases of multiple ectopic tissues.
ABSTRACT
La tiroides ectópica lingual es una patología muy poco frecuente, producida por la detención en el descenso normal de la glándula durante el desarrollo embrio-nario. La localización lingual de tejido tiroideo es la más común entre las tiroides ectópicas o aberrantes. Esta enfermedad puede ser asintomática pero, cuan-do los signos y síntomas están presentes, guardan estrecha correlación con la localización de la lesión y son proporcionales a su tamaño. El diagnóstico debe realizarse clínicamente y con el complemento de es-tudios por imágenes y endocrinológicos. En los aná-lisis de laboratorio se debe incluir dosaje de las hor-monas TSH, T4 libre y T3, vinculadas con la función tiroidea. Las biopsias deben evitarse ya que causan desequilibrio en la producción hormonal de la glándu-la y peligro de profusas hemorragias. En este artículo se desarrolla una descripción de las generalidades de la tiroides ectópica lingual, y se presenta un caso clínico de un niño con un tumor lingual, que fue deri-vado por su médica pediatra a cirugía para realizar una biopsia. Asimismo, se comenta la importancia que tiene para el odontólogo conocer esta patología a fin de poder evitar sus posibles complicaciones (AU)
Lingual thyroid is a rare disorder produced by a failure in the descent of thyroid gland to its normal position during embryological development. Lingual localization of thyroid tissue is the most common among the ectopic or aberrant thyroids. This condition can be asymptomatic, although when symptoms take place, they are connected to the lesion location and depend on its size. Diagnosis should be made clinically and complemented with imaging and endocrine studies. Laboratory analysis must include dosage of TSH, free T4 and T3, thyroid function-linked hormones. Due to the possible imbalance in the gland hormone production and the risk of massive bleeding, biopsy should be avoided. In this article, a brief description of lingual ectopic thyroid generalities is developed and a clinical case of a 7-years old child is provided. Additionally, dentistry importance of knowing this condition is commented, in order to prevent its possible complications (AU)

Objetivo: reportar el caso de una paciente con diagnóstico de tejido mamario ectópico en vulva, y realizar una revisión de la literatura acerca del diagnóstico, tratamiento y pronóstico de esta condición en esta localización. Materiales y métodos: paciente de 49 años consulta por masa vulvar dolorosa a un centro privado de nivel medio de complejidad ubicado en Bogotá, Colombia. Se realizó ecografía de la lesión y posteriormente escisión quirúrgica; la histopatología mostró tejido mamario ectópico sin malignidad. Se realizó una búsqueda en las bases de datos PubMed, Embase, Cochrane, LILACS y Scielo, con las palabras clave "Vulva", "Glándulas mamarias", "ectópico", "Vulva", "Breast" y "Ectopic", y se incluyeron reportes y series de caso de mujeres con tejido mamario en vulva confirmado por histopatología. Resultados: se identificaron 184 títulos, de los cuales 94 fueron finalmente incluidos para un total de 126 casos. El 57,9% eran tumores benignos, con un 95% en mujeres menores de 50 años; y el 42,06% eran tumores malignos, el 92 % en mujeres mayores de 50 años. El diagnóstico se realizó por clínica, con imágenes diagnósticas complementarias, marcadores tumorales e inmunohistoquímica en algunos casos. Se realizó escisión local en el 91% de los casos de patología benigna y 43% de patología maligna, siendo el método diagnóstico y terapéutico. Conclusión: el tejido mamario ectópico en vulva debe ser considerado como parte del diagnóstico diferencial de masas a nivel vulvar con diferente pronóstico en mujeres pre y posmenopáusicas. Se requieren más estudios para una mejor caracterización de la patología y definir el tratamiento ideal en términos de recaída y supervivencia.
Objective: To report the case of a patient diagnosed with ectopic mammary tissue in the vulva, and to conduct a literature review of the diagnosis, treatment and prognosis of this condition in that location. Material and methods: A 49-year-old patient who presented with a painful vulvar mass to a private intermediate complexity center in Bogotá, Colombia. The lesion was assessed on ultrasound and then surgically excised; histopathology showed ectopic mammary tissue with absence of malignancy. A search was conducted in the PubMed, Embase, Cochrane, LILACS and Scielo databases using the keywords "Vulva," "Breast" and "Ectopic." Case reports and case series of women with histopathology-confirmed mammary tissue in the vulva were included. Results: Overall, 184 titles were identified and, of these, 94 were ultimately included, for a total of 126 cases, with 57.9% being benign tumors, 95% in women under 50 years of age, and 42.06% being malignant tumors, 92% in women over 50 years of age. Diagnosis was made on the basis of the clinical findings, with ancillary diagnostic imaging, tumor markers and immunohistochemistry in some cases. Local excision was performed in 91% of cases with benign pathology and in 43% of cases with malignant pathology, with the diagnostic method being therapeutic. Conclusion: Ectopic mammary tissue in the vulva must be considered as part of the differential diagnosis of vulvar masses, prognosis being different in pre and postmenopausal women. Further studies are needed to enhance the characterization of this condition and define the ideal course of treatment in terms of relapse and survival.

El adenoma pleomórfico es una de las neoplasias más frecuentes que puede originarse en la glándula lagrimal, pero su origen en tejido ectópico subconjuntival, palpebral e intraocular ha sido escasamente reportado. Se presentó el caso de una paciente femenina de 60 años con tumor en órbita anterior de 4 meses de evolución, localizado por encima del párpado superior, dolorosa, firme, de 8 mm de superficie lisa, con Tomografía Axial Computarizada que informa proceso quístico V/S neoformativo. Se realizó biopsia excisional donde se encuentra nódulo tumoral bien delimitado de composición bifásica con abundante matriz cartilaginosa y mixoide, elementos mioepiteliales, epiteliales ductales y escamosos lo que establece el diagnóstico definitivo de adenoma pleomórfico. El tejido lagrimal ectópico constituye un dilema y una neoplasia originada en ellos constituye mayor problema aun. Los avances en la cirugía oftalmológica han permitido el diagnóstico y cirugía temprano de lesiones tumorales de esta localización para beneficio de los pacientes.
The pleomorphic adenoma is one of the most frequent neoplasia that could be originated in the tear gland, but its origin in subconjunctival, palpebral and intraocular tissue has been scarcely reported. We present the case of a female patient aged 60 years with a hard, painful tumor in anterior orbit of fourth months’ evolution, located over the higher eyelid, of 8 mm plain surface; the computerized axial tomography shows a neoformative cystic V/S process. We carried out scissional biopsy finding a well-delimitated, biphasic-composition tumoral nodule with large amount of cartilaginous and mixed, myoepithelial, ductal epithelial and squamous elements, helping to establish the definite diagnosis of pleomorphic adenoma. The ectopic lacrimal tissue is a dilemma and neoplasia originated in them is still a bigger problem. The advances in ophthalmologic surgery have allowed the early diagnosis and surgery of the tumoral lesions in this location for the patients’ sake.
ABSTRACT
Scintigraphy (CGF) is a diagnostic imaging tool utilizing specific radiopharmaceuticals to assess the anatomical and functional status for each organ or tissue. This technology allows the veterinarian to anticipate, supplement or complete the diagnosis, and also to monitor the treatment. Unfortunately, this diagnostic method is little known, and its lack of dissemination among clinical veterinarians prevents its optimal use. In order to understand the benefits of CGF as an effective imaging tool in the city of Buenos Aires during the years 2004-2006, we analyzed the studies that utilized CGF in canine and cats during this period. From a total of 142 studies, it was found that 38.6% of the assessments corresponded to thyroid disorders, while 61.4% of the remaining studies that involved CGF included, in descending order, pathologies associated with liver, bone, kidneys, parathyroid gland and lungs. The main findings in this paper highlight the use of CGF in the diagnosis of functional thyroid carcinoma followed by portosystemic shunt, bone neoplasms, evaluation of individual kidney function, parathyroid hyperplasia, parathyroid adenoma and pulmonary embolism.
La centellografía (CGF) es una ayuda diagnóstica a través de imágenes, que permite evaluar el estado anatómico-funcional por medio del empleo de radiofármacos específicos para cada órgano o tejido en los animales de compañía, permitiendo anticipar, complementar o concluir un diagnóstico, al igual que permite hacer el seguimiento al tratamiento instaurado. Lamentablemente es un método diagnóstico muy poco conocido y difundido entre los clínicos veterinarios, llegando a omitirse su realización. Con el propósito de conocer los diferentes tipos de estudios, aportes e indicaciones que se obtuvieron mediante el uso de la cámara gamma en la ciudad de Buenos Aires durante los años 2004-2006, se analizaron los informes de los estudios CGF que fueron realizados a caninos y felinos durante este periodo. Al finalizar el estudio se logro determinar que el 38.6% del total de los 142 estudios correspondía a evaluaciones de la glándula tiroides, mientras el 61.37% estaba constituido por cinco diferentes estudios entre los que se mencionan en orden decreciente, CGF hepática, ósea, renal, paratiroidea y pulmonar. Las principales indicaciones encontradas en el presente trabajo se destacó el diagnóstico de carcinoma de glándula tiroides funcional seguido por el shunt porto sistémico, neoplasias de tejido óseo, evaluación de la función renal individual, hiperplasia paratiroidea, adenoma paratiroides y embolismo pulmonar.

ABSTRACT
Ectopic liver is a rare entity that has been previously identified during abdominal exploration for other surgery and this has usually been described in the vicinity of the liver such as on the gallbladder, hepatic ligaments, diaphragm, thoracic cavity, adrenal glands, pancreas, omentum, spleen, esophagus and umbilical cord. Most cases of ectopic liver reported in the literature were located in the gallbladder. We report here on a case of ectopic liver related to the gallbladder, and this was encountered during an elective laparoscopic cholecystectomy.
ABSTRACT
Although intrathoracic liver in association with a congenital diaphragmatic hernia has been well documented, the finding of intrathoracic ectopic liver tissue in the presence of an intact diaphragm is an extremely rare congenital anomaly. We have experienced a case of intrathoracic ectopic liver without any diaphragmatic hernia. A 37-year-old woman was admitted for the treatment of an incidentally detected right lung mass. A chest computed tomography scan revealed a right lower lobe lung mass close to the diaphragm, and this was suspicious for bronchial carcinoid tumor. Upon surgery, 2 round solid masses 3.5x3.5 cm and a 2.0x2.0 cm in size were noted, with their bottoms attached to the diaphragm dome. The masses were completely resected. Histologically, they were confirmed to be intrathoracic ectopic livers. The patient had an uncomplicated postoperative course.

There are few reports of the endoscopic and histological features of ectopic sebaceous glands in the esophagus. Recently we observed a 2 mm whitish flat elevated nodule in the lower esophagus. A biopsy was taken under the clinical impression of a papilloma or ulcer scar. Histology revealed normal esophageal mucosa with mature ectopic sebaceous glands located in the lamina propria with no visible hair follicles. We report this case with a brief review of the literature related to the histological findings and histogenesis of esophageal ectopic sebaceous glands.

Ectopic cervical thymus is an extremely uncommon etiology of neck mass in infants. We report a case of ectopic thymus in five months old male baby, presenting as a submandibular mass. Ultrasonography and CT scan revealed a 5.2 x 1.6 x 1.5 cm-sized solid mass in the left suprahyoid neck between parotid and submandibular gland, which was regarded as malignant lesion though it was soft, non-tender on examination. For differential diagnosis of malignant lymphoma and soft tissue sarcoma, an incisional biopsy was performed to confirm ectopic cervical thymus. He is under our observation without having gone through surgical excision because the thymus will involute spontaneously and he has no symptoms.

Ectopic thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue in sites other than in its usual pretracheal region. Lingual thyroid, although it is the most common manifestation of benign ectopic thyroid tissue, is still a rare clinical entity. Thyroid hemiagenesis is also a very rare abnormality, in which one thyroid lobe fails to develop. We report a case of left thyroid hemiagenesis and goiter in the right lobe of a 26-year-old female patient with ectopic lingual thyroid.

A single dysplastic ectopic kidney associated with ectopic ureter or ureterocele defies detection even with repeated examinations using conventional imaging modalities and cystovaginoscopy under anesthesia, thus leading to significant delay in diagnosis and appropriate treatment. Laparoscopy can be a useful modality for the diagnosis, and also the treatment, of small ectopic kidney not found with conventional diagnostic method. We report three cases of transperitoneal laparoscopic nephrectomy for ectopic dysplastic kidney.
