ABSTRACT

Granulomatous appendicitis is uncommon and can be caused by Crohn's disease, foreign body reactions, infections or sarcoidosis. We report a 26-year-old female consulting in the emergency room for pain in the right lower abdomen. She was released with analgesics and consulted 14 days later for the same pain. This time she was operated with the preoperative diagnosis of appendicitis. The pathological study of the surgical piece was compatible with a granulomatous appendicitis caused by sarcoidosis.

ABSTRACT

La úlcera genital aguda (UGA) o úlcera de Lipschütz constituye una infrecuente entidad clínica caracterizada por la aparición de úlceras genitales en niñas y adolescentes que no han iniciado su actividad sexual. El cuadro es de inicio agudo, con formación de úlceras dolorosas habitualmente precedidas en su aparición por manifestaciones sistémicas tales como fiebre, cefalea, astenia, adinamia, mialgias y adenopatías inguinales, y donde el estudio microbiológico de la lesión descarta un posible origen infeccioso. A pesar de presentar un cuadro clínico característico, esta enfermedad constituye una entidad poco conocida y por tanto subdiagnosticada, motivo por el cual presentamos el caso de una paciente de 10 años con diagnóstico de UGA realizado en el Departamento de Dermatología de la Pontificia Universidad Católica de Chile.


Acute genital ulcer (AGU) or Lipschütz ulcer is a rare clinical entity characterized by the appearance of genital ulcers in children and adolescents who have not initiated sexual activity. The picture is of acute onset, with formation of painful ulcers on their occurrence usually preceded by systemic manifestations such as fever, headache, fatigue, weakness, muscle pain and inguinal lymphadenopathy, and where the microbiological study of injury rule out a possible infectious origin. Despite presenting a characteristic clinical picture, this disease is a little known entity and under diagnosed, we present the case of a 10 years old girl diagnosed with UGA conducted at the Department of Dermatology, Catholic University of Chile.

ABSTRACT

Background: Perforation is an unusual presentation of gastric cancer. There is disagreement about its prognosis and treatment. Aim: To describe the clinical, morphological, therapeutic and prognostic features of perforated gastric cancer. Material and Methods: Reviewing the registry of a pathology laboratory in a general hospital, 13 patients with perforated gastric cancer, aged 48 to 75 years and operated in a period of 20 years, was identified. The medical records of these patients were reviewed and eventual deaths were identified using death certificates. Results: A gastrectomy was performed in 9 cases and lymph node dissection in six. Seventy eight percent were T4 tumors and all patients in whom a lymph node dissection was done, had lymph node involvement. In 10 cases, the preoperative diagnoses were a perforated peptic ulcer. Mean global survival was six months. The figures for patients subjected or not subjected to gastrectomy were 21.5 and 3.7 months, respectively (p < 0.01). One of five patients subjected to emergency surgery, died. Conclusions: Perforation occurs usually in advanced stages of gastric cancer and older patients. In this report those patients subjected to gastrectomy have a better survival.


Introducción: El cáncer gástrico perforado (CGP) es una infrecuente forma de presentación de la enfermedad. Su pronóstico y manejo quirúrgico son motivo de controversias. El objetivo de este estudio es describir variables clínico-morfológicas de pacientes con CGP junto con valorar el tratamiento e impacto en la supervivencia (SV) de estos pacientes. Material y Método: Estudio de cohorte histórica. Se estudiaron variables clínico-morfológicas, de tratamiento y SV de pacientes con CGP sometidos a cirugía radical o paliativa en el Hospital Hernán Henríquez Aravena de Temuco entre enero de 1986 y diciembre de 2007 (n = 13). Utilizando los paquetes estadísticos Epi-info 6.0 y Stata 9.0, se aplicó estadística descriptiva, analítica y análisis de SV. Resultados: Se constató 13 casos de CGP (1,8 por ciento) con un promedio de edad de 64,2 años (35-75 años). Se efectuó gastrectomía en 9 pacientes (69 por ciento) en 6 de ellos con disección ganglionar. El 78 por ciento correspondió a tumores T4 y todos los casos con disección ganglionar presentaron compromiso de los linfonodos. En 10/13 el diagnóstico pre-operatorio fue úlcera péptica perforada (UPP) permitiendo los hallazgos intra-operatorios sospechar el carácter neoplásico maligno en 10/13 casos. El promedio de SVglobal fue 16 meses, siendo de 21,5 y 3,7 meses (p < 0,001) para el subgrupo sometido a gastrectomía y reparación respectivamente. La mortalidad quirúrgica en sujetos sometidos a gastrectomía de urgencia fue 20 por ciento (1/5). Conclusiones: La perforación gástrica se presenta habitualmente en pacientes mayores y con estadios avanzados de la enfermedad, nuestros pacientes gastrectomizados con intención curativa mostraron mejores resultados de supervivencia.

ABSTRACT

Background: We report a 74 years old male consulting for multiple painless non pruriginous pink plaques and nodules of truncal distribution that appeared 15 days earlier. A skin biopsy disclosed a blastic plasmocytoid dendritic cell neoplasm. A staging CAT scan showed lymphadenopathies located around the trachea and its bifurcation. A bone marrow biopsy did not show tumor infiltration. The patient has been treated with four cycles of cyclophosphamide-doxorubicin-vincristine-prednisone, obtaining a partial remission of the lesions.

ABSTRACT

El mucocele apendicular (MA) corresponde a una dilatación quística del lumen apendicular rellena por mucus en su interior; secundario a etiologías de naturaleza benigna (hiperplasia mucinosa y cistoadenoma) o maligna (cistoadenocarcinoma).Se trata de una condición infrecuente, reportándose en no más allá del 0,3 por ciento de las apendicectomías. Su tamaño y manifestaciones clínicas son extremadamente variables, permitiendo el estudio anatomo-patológico de la pieza quirúrgica establecer el diagnóstico etiológico. Presentamos el caso de un MA gigante secundario a un cistoadenoma mucinoso, diagnosticado en un hombre de 57 años en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez Aravena de Temuco...


Appendiceal mucocele (AM) is a cystic dilatation of the appendiceal lumen filled by mucus inside, secondary to benign etiologies (hyperplasia and mucinous cystadenoma) or malignant (cystadenocarcinoma). This condition is uncommon, being reported in no more than 0.3 percent of appendectomies. Its size and clinical manifestations are extremely variable, allowing the pathological analysis of the surgical specimen etiologic diagnosis. We report a case of a giant AM secondary to a mucinous cystadenoma diagnosed in a 57-year-old man in the Pathology Unit of Hospital Hernán Henríquez Aravena of Temuco...

ABSTRACT

El hamartoma peribiliar (HPB) o adenoma de conductos biliares corresponde a un tumor hepático benigno, que representa tan solo el 1,3 por ciento de todos los tumores primarios del hígado. Macroscópicamente corresponde a una lesión redondeada bien delimitada, subcapsular, siendo habitualmente diagnosticado como un hallazgo intra-operatorio o de autopsia. Se presentan dos pacientes con diagnóstico incidental de HPB realizado en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez de Temuco.


Peribiliary gland hamartoma (PGH) or bile duct adenoma corresponds to a benign liver tumor, which represents only 1.3 percent of all primary liver tumors. Corresponds to a macroscopically well-defined round lesion, subcapsular, and is usually diagnosed as an intra-operative findings or autopsy. We report two patients with incidental diagnosis of PGH conducted in the Pathology Unit of the Hospital Hernán Henríquez in Temuco.

ABSTRACT

La pericarditis tuberculosa (PT) representa una rara manifestación extrapulmonar de tuberculosis (TBC), que se encuentra en aproximadamente el 1 por ciento de las autopsias por TBC y 1-2 por ciento de casos de TBC pulmonar, estando su presentación estrechamente asociado con la infección por VIH. El compromiso pericárdico ocurre habitualmente por diseminación linfática retrógrada o diseminación hematógena desde un foco pulmonar primario, pudiendo clínicamente manifestarse como derrame pericárdico, pericarditis constrictiva o un patrón mixto. El presente trabajo, describe los hallazgos clínicos y morfológicos de un caso de PT en un sujeto inmunocompetente de 78 años, con diagnóstico de PT constrictiva efectuado en el Hospital Hernán Henríquez Aravena de Temuco.


Tuberculous pericarditis (TP) is a rare manifestation of extrapulmonary tuberculosis (TBC), found in approximately 1 percent of autopsies by TB and 1-2 percent of cases of pulmonary TB, while his presentation closely associated with the HIV infection. The pericardial involvement usually occurs by retrograde lymphatic spread or hematogenous spread from a primary pulmonary focus, which may clinically manifest as pericardial effusion, constrictive pericarditis or a mixed pattern. This paper describes the clinical and morphological findings of a TP case in an 78-year old immunocompetent patient, with constrictive TP diagnosed made in the Hospital Hernán Henríquez Aravena in Temuco.

ABSTRACT

Pseudolinfoma cutáneo es el término utilizado para indicar un grupo de trastornos linfoproliferativos benignos de la piel, siendo el linfocitoma cutis una forma de seudolinfoma de células B. Clínicamente se manifiesta como nódulos o placas solitarias, generalmente localizados en la cara de mujeres jóvenes. Su etiopatogenia estaría relacionada con una respuesta inmunológica local exagerada ante diversos desencadenantes tales como, picadura de insectos, acupuntura, vacunas, tatuajes, medicamentos e infecciones. Se presentan dos casos de pacientes con diagnóstico de linfocitoma cutis realizado en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez de Temuco.


Cutaneous pseudolymphoma is the term used to indicate a group of benign lymphoproliferative disorders of the skin, being the cutaneous lymphomas a form of B-cell pseudolymphoma. Clinically it manifests as solitary nodules or plaques, usually located on the face of young women. Its pathogenesis could be related to an exaggerated local immune response to various causes such as insect bites, acupuncture, vaccinations, tattoos, drugs and infections. We present two cases of patients diagnosed with skin linfocitoma made in the Pathology Unit in Hernán Henríquez Hospital of Temuco.

ABSTRACT

La tuberculosis gastrointestinal (TB GI) representa el 3-5 por ciento de todos los casos de TB extrapulmonar, reportándose que hasta el 20 por ciento de los sujetos con TB pulmonar presentan manifestaciones extra-pulmonares que incluyen enfermedades intra-abdominales, sin embargo, se desconoce la real incidencia del compromiso intestinal. La región ileocecal representa el sitio anatómico más frecuentemente afectado (85-90 por ciento), siendo actualmente la colonoscopía la herramienta diagnóstica de mayor utilidad. Se presentan los hallazgos morfológicos del examen post-mortem de una paciente en estudio por baja de peso y masa en región cecal. La necropsia realizada en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez Aravena de Temuco concluyó una TB pulmonar bilateral con compromiso secundario intestinal y linfonodal.


Gastrointestinal tuberculosis (TB GI) represents 3-5 percent of all cases of extrapulmonary TB, studies report that up to 20 percent of patients with pulmonary TB have extra-pulmonary manifestations. However, the real incidence of intestinal involvement is unknown. The ileocecal region is the anatomical site most frequently affected (85-90 percent), and colonoscopy is currently the most useful diagnostic tool. Post-mortem morphological elements of the examination of a patient with weight loss and cecal mass are presented. The necropsy performed at the Department of Pathology of the Hospital Hernán Henríquez of Temuco concluded a bilateral pulmonary TB with intestinal and lymph node involvement.

ABSTRACT

In only 2% of all cases of hydatidosis, the cysts are located in the brain. We report a 12-year-old male, a 5-year-old girl and a 19-year-old female consulting for intracranial hypertension and a 13-year-old male consulting for a left hemiparesis. Imaging studies found intra-cerebral cysts with characteristics of hydatidosis in all. All lesions were completely removed surgically and the pathological study of the excised piece confirmed the diagnosis of hydatidosis.

ABSTRACT

Intravascular large B cell lymphoma is a rare subtype of large cell lymphoma that is characterized by the proliferation of lymphoid cells within the lumina of small blood vessels. We report a 61-year-old male presenting paresis of both lower limbs, confusion and a history of weight loss. Magnetic resonance and CAT imaging studies showed multiple images of brain and cerebellar infarctions. Twenty days after admission, the patient died and the postmortem study demonstrated a multisystem intravascular large B cell lymphoma.

ABSTRACT

Los sarcomas uterinos son relativamente raros. El tipo histológico más frecuente es el leiomiosarcoma, seguido por el sarcoma del estroma endometrial. Los rabdomiosarcomas (RMS) son neoplasias malignas con diferenciación muscular esquelética. El rabdomiosarcoma embrionario (RMSE) tipo botrioide es el sarcoma más común de la infancia; con escasos reportes en adultos, afectando la región de cabeza y cuello, tracto genitourinario y extremidades más frecuentemente. En el tracto genitourinario, la vagina es la localización mas frecuente, comprometiendo en raras ocasiones el cuello o fondo uterino. Se presentan las características clínicas y morfológicas de un caso de RMSE uterino tipo botrioide diagnosticado en una paciente de 58 años en la Unidad de Anatomía Patológica del Hospital Hernán Henríquez Aravena de Temuco.


Uterine sarcomas are relatively rare. The most common histological type is leiomyosarcoma, followed by endometrial stromal sarcoma. The rhabdomyosarcoma (RMS) are malignant neoplasms with skeletal muscle differentiation. Embryonal rhabdomyosarcoma (RMSE) type botryoides is the most common in childhood, with few reports in adults, affecting the head and neck region, genitourinary tract and extremities more frequently. In the genitourinary tract, the vagina is the most common location, rarely involving cervix and fundus uterine. Clinical and morphological characteristics are presented of a case of uterine RMSE diagnosed in a 58 year-old woman in the Pathology Unit of the Hernán Henríquez Aravena Hospital in Temuco.

ABSTRACT

Se define como himen complaciente (HC) aquel himen que se distiende sin dañarse durante la penetración al momento de la relación sexual, por lo que no quedan lesiones atribuibles al acto sexual. Su hallazgo al momento de realizar el peritaje médico-legal impide afirmar la existencia de penetración total o parcial en el acto denunciado. El objetivo de este trabajo es determinar la prevalencia de HC junto con analizar variables socio-bio-demográficas en mujeres que denuncian ser víctima de una agresión sexual. Se realizó un estudio retrospectivo-descriptivo, seleccionándose de la Unidad de Sexología Forense del Servicio Médico Legal de Temuco las denuncias por violación realizadas entre Enero/2000­ Diciembre/2003 (n=509). Los datos se registraron en planilla Excel y analizados con el software Winstat para Excel. Se verificó 46 mujeres con HC (9 por ciento). El 74 por ciento de las víctimas con HC pertenecía al área urbana, siendo el promedio de edad 16,7 años. El 51,2 por ciento denunció múltiples violaciones y el 89,2 por ciento de los imputados resultaban ser conocidos de la víctima. Al examen físico se constató lesiones extragenitales y coloproctológicas en el 29,9 por ciento y 4,4 por ciento respectivamente. Dentro de las pruebas biológicas realizadas, en el 8,7 por ciento se evidenció la presencia de espermios. En el 9 por ciento de las mujeres que denuncian ser víctima de violación se constata HC. Al examen físico se encuentra algún tipo de lesión en sólo el 28,3 por ciento, mientras que en el 8,7 por ciento se demuestra la presencia de espermios. Con estos resultados son escasas las evidencias que permiten al médico sugerir la existencia de un atentado sexual con o sin penetración total o parcial.


Dilatable or complacent hymen is defined as that which can be stretched without being damaged during sexual intercourse, and is the reason as to lack of injuries present that are attributable to the sexual act. The findings at the time the legal medical expert work is carried out, cannot confirm the existence of total or partial penetration in the denounced cases. The objective of this study was to identify the prevalence of dilatable or complacent hymens and analyze the social-bio-demographic factors of the victims of sexual assault. A descriptive, retrospective study was carried out selecting the reports of rapes from the Sexology Unit of the Legal Medical Service in the city of Temuco, between January 2000 and December 2003 (n=509). The information was registered with Excel program and analyzed by Winstat Software for Excel program. Dilatable or complacent hymen in 46 cases (9 percent), 74 percent of the victims were from urban areas, with an average of 16.7 years of age. 51.2 percent reported several episodes and 89.2 percent of the aggressors were individuals familiar to the victim. During physical examination extra genital and colorectal injuries were noted in 29.9 percent and 4.4 percent respectively. During biological exams presence of spermatocytes was confirmed in 8.7 percent. Dilatable or complacent hymen was reported in 9 percent of the rapes. During physical examination evidence of injury is reported only in 28.3 percent, while there is evidence of spermatocytes in 8.7 percent of the victims. As result there is little evidence that allows the physician to determine the existence of a sexual assault with or without penetration.

ABSTRACT

Background: The frequency of appendicular presence of Enterobius vermicularis varies from 0.2 to 41.8 percent. It is generally a pathological finding. The luminal obstruction by the parasite may unveil an acute appendicitis. Aim: To study the frequency of Enterobius vermicularis presence in surgical pieces of appendectomies. Material and Methods: Analysis of surgical pieces of appendectomies processed at the pathology laboratory of a general hospital, between 1993 and 2010. Results: In 21.038 surgical pieces, the presence of Enterobius vermicularis was found in 322 (1.5 percent). Fifty nine percent were women and 71 percent were younger than 18 years. Acute inflammation was confirmed in 71 percent. A history of previous abdominal pain was present in 40 and 70 percent of patients with and without acute inflammation in the surgical piece. Conclusions: In this series, the frequency of Enterobius vermicularis presence in surgical pieces of appendectomy was 1.5 percent.


Introducción: La frecuencia de Enterobius vermicularis (EB) apendicular varía entre 0,2-41,8 por ciento, siendo generalmente su diagnóstico un hallazgo al estudio histopatológico. La obstrución luminal puede desencadenar un cólico apendicular o evolucionar a una apendicitis aguda, siendo por tanto una causa frecuente de apendicectomía. El objetivo del estudio es determinar la prevalencia de EB en piezas quirúrgicas de apendicectomía junto con describir características clínico-morfológicas. Material y Método: Cohorte retrospectiva de pacientes con oxiuriasis apendicular diagnosticados en el Hospital Hernán Henríquez Aravena entre 1993-2010. Se estudiaron variables clínico-morfológicas, utilizándose estadística descriptiva y analítica, aplicando Chi-cuadrado y test exacto de Fisher para variables categóricas y T-student para variables continuas con un IC de 95 por ciento. Resultados: En 21.038 apendicectomías se verificaron EB en 322 casos (1,53 por ciento). El 59 por ciento eran mujeres y 71 por ciento menor de 18 años. Inflamación aguda fue confirmada en 71 por ciento. En casos con inflamación aguda la temperatura rectal y recuento leucocitario promedio fue 380 C y 12.975 mm³ respectivamente, mientras que en casos sin inflamación 37,80 C y 10.984 mm³ (p = N.S). En el grupo apendicectomizado por sospecha de apendicitis el 40 por ciento tenía historia de dolor abdominal previo, mientras que en aquellos sin inflamación aguda asociada el 72 por ciento (p = 0,005). Conclusiones: La prevalencia de EB apendicular fue 1,53 por ciento, afectando fundamentalmente a niños-jóvenes del sexo femenino. La oxiuriasis apendicular representa una causa de dolor abdominal interpretado como apendicitis aguda, sin asociarse a inflamación en el examen anatomopatológico. La historia de dolor abdominal previo resultó una variable útil para discriminar cólico apendicular de apendicitis aguda.

ABSTRACT

Sertoli Cell Tumors are less than 1 percent of all testicular tumors. We report a 14-year-old male presenting with a left testicular mass. Orchiectomy was carried out and the pathological study informed a large cell calcifying Sertoli cell tumor (LCCSCT). Its association with the Carney complex and Peutz-Jeghers Syndrome was subsequently discarded. Surgical excision was completed with a radical orchiectomy. After eight months of follow up, there is no evidence of tumor relapse.

ABSTRACT

We report a 54-year-old male that, after working in a rural zone of Rio de Janeiro, Brazil, presented with an itching cutaneous lesion in the wrist with a black small central zone. The patient extracted from the lesion a on of 0.5 mm diameter. The pathological study of the insect recognized its body segments. The epidemiological background and the characteristics of the lesion led to the diagnosis of tungiasis.
