We report three cases of male breast myofibroblastoma. This uncommon benign tumor arises from breast mesenchyma and is more frequently seen in adult men. Mammographic findings consist of a well-delimited, round to oval dense mass, variable in size but usually 1-4 cm in diameter. No microcalcifications were observed. Ultrasonography confirms the sol...

Background Melanomas that initially affect lymph nodes, with no identified primary lesion, have traditionally been included within the group of metastatic melanomas of unknown origin (MMUO).There are variations between the various data presented in the literature. Its natural history is not well defined and there are no clear guidelines for treatme...

Historically it has been considered to be the Pap cytology not sensitive for the diagnosis of the glandular neoplasias of cervix uterine. The improvement in the representation of glandular endocervical cells and in the cytological interpretation close to HPV's test it can improve the diagnosis of adenocarcinoma in situ and help to diminish the inci...

Valoración preliminar con CINtecPLUS (tinción dual) en grupos densos hipercromáticos en citología líquida de cuello uterino. Los hallazgos apoyan su posible utilidad para el diagnóstico de lesiones de alto grado. The findings support their potencial usefulness

Primitive neuroectodermal tumor/Ewing ́s sarcoma (PNET/ES) is an uncommon type of small round blue cell tumors; it rarely originates and develops in cutaneous and subcutaneous tissue and this characteristic seems to be linked to a better prognosis. However, there is no consensus on the treatment and combined therapies are the most extended choice,...

We present histopathology images, and molecular data of two cases of superficial Ewing sarcoma (cutaneous / subcutaneous), both with favorable biological behavior after wide surgical resection (follow-up of 13 and 26 years). We comment that the decision of the oncologist doctors not to add a complementary treatment with chemotherapy or radiotherapy...

Background: Although dual staining (p16/Ki-67) (DS) is considered a promising method to identify premalignant and malignant cervix lesions but there is no agreement on its role in the cervix cancer screening protocol. In the present work we share our modest experience using DS as an immunocytochemistry technique more, within the diagnostic routine...

Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm (0.4% of soft tissue sarcomas) originating from fol-licular dendritic cells. On the other hand, Castleman's disease (CD) is a rare lymphoproliferative disorder first described in 1956 by Castleman et al. as a benign, localized enlargement of hyperplastic lymph nodes. Castle-man's disease h...

Las normas sobre el cribado para la prevención del cáncer del cuello uterino han sufrido grandes cambios en los últimos años y se siguen produciendo modificaciones con el fin de establecer la mejor guía que contribuya a su detección precoz en fases pre-cancerosas o iniciales. Presentamos nuestra experiencia con estudio combinado de citología líquid...

8137 cases (of 5817 women) were examined with combined study Pap cytology/hpv in Onkologikoa Hospital during the period 2006-2013. 1404 cases (792 patients) showed test combined hpv-positive and PAP cytology-negative and of them 674 patients did not have precedents of previous CIN. In the review of the clinical history realized in February 2014, of...

Lobular breast carcinoma represents 2-20% of infiltrative carcinomas of the breast. The incidence of extrahepatic gastrointestinal (GI) tract metastases observed in necropsy studies varies from 6% to 18% and the most commonly affected organ is the stomach, followed by colon and rectum [1-4]. Reported herein is the case of a 67-year-old woman who wa...

Case report A 74 year old woman with systemic lupus erithematosus (SLE) and lupus panniculitis had clinical and radiological findings suspicious of malignancy in both breasts. Pathology A mucinous carcinoma was diagnosed in the left breast and histological changes suggestive of lupus mastitis were found in both breasts. Discussion This unusual ca...

Granular cell tumors (GCT) of the breast are uncommon benign neoplasms that are usually indistinguishable from breast cancer with respect to their clinical and radiological presentation. FNAB can be a useful diagnostic tool, but histological examination is essential for the correct diagnosis. This benign tumor should be considered among the diagnos...

Se presenta un caso de condrosarcoma mesenquimal extraesquelético de región pectoral en un paciente de 35 años. El diagnóstico diferencial se basó en la demostración ultraestructural de organelas típicas de células condroides.
