Secretory breast carcinoma: a report of two cases / Carcinoma secretor de la mama: reporte de dos casos

Secretory breast carcinoma was first described by McDivitt and Stewart in 1966, who reported seven cases of this tumoural strain in children and therefore named it "juvenile carcinoma". However, a couple of decades later, Tavassoli and Norris reported a series of 19 cases and found that most occurred in adults, and therefore they proposed changing its name to "secretory carcinoma." Since then, approximately 100 cases have been reported in the world literature. We present two cases treated with total mastectomy and sentinel node biopsy with excellent outcome. To our knowledge, only a few cases have been reported in Latin American patients

El carcinoma secretor dela mama fue inicialmente descrito por McDivitt y Stewartin en 1966, en su artículo, siete casos de este tipo de tumor se presentaron en niños, por lo tanto, se le asignó el nombre de "carcinoma Juvenil", pero un par de décadas después Tavassoli y Norris encontraron en su serie de 19 casos, que la mayoría eran adultos, y así propusieron cambiar el nombre a Carcinoma secretor. Desde ese momento aproximadamente 100 casos han sido reportados en la literatura. Nosotros presentamos dos casos tratados con mastectomía y ganglio centinela, con excelente pronóstico. Hasta donde sabemos, esta patología se ha reportado escasamente en pacientes latino americanos

Asociación entre telorragia y cáncer de mama en una unidad médica de alta concentración / Association between telorragia and breast cancer in a high concentration medical unit

Resumen OBJETIVO: Determinar la asociación entre telorragia y cáncer de mama en población mexicana atendida en una unidad médica de alta concentración. MATERIALES Y MÉTODOS: Estudio observacional, retrospectivo y analítico efectuado en pacientes con telorragia atendidas entre enero de 2007 y diciembre de 2016 en la Fundación de Cáncer de Mama (FUCAM). Se efectuó el cálculo de proporciones y un subanálisis "tipo nodo" entre telorragia más nódulo versus telorragia sola, mediante χ2, riesgo relativo e intervalo de confianza al 95% con el paquete estadístico SPSS 23.0. RESULTADOS: Se estudiaron 169 pacientes, 42 de ellas con diagnóstico definitivo de cáncer de mama. La telorragia se asoció en 24.8% con cáncer, y cuando estuvo asociada con un nódulo la probabilidad de malignidad fue de 63%. Al comparar los subgrupos: telorragia más nódulo vs telorragia sola, se encontró una razón de momios de 4.2 para el primer grupo (IC95%: 2.5-6.8; p < 0.001). CONCLUSIONES: Este estudio demostró que la probabilidad de malignidad en los casos de telorragia sola en población mexicana, en un hospital de referencia, se encuentra en el límite alto en relación con el histórico mundial, y cuando se asocia con un nódulo la probabilidad es significativamente mayor.

Absract OBJECTIVE: To determine the association between telorragia and breast cancer in a Mexican population in a highly concentrated Medical Unit. MATERIALS AND METHODS: Observational, retrospective, analytical study in patients with telorragia treated at FUCAM from January 2007 to December 2016. Proportion calculation and a "node type" sub-analysis were carried out, between telorragia plus nodule versus telorragia alone, by means of χ2, relative risk, and 95% confidence interval with statistical package SPSS 23.0. RESULTS: 169 patients were studied, 42 of them presented a definitive diagnosis of breast cancer. The telorragia was associated in 24.8% to cancer, and when it was associated with nodule the probability of malignancy was 63%. When comparing the subgroups with more nodule vs telorrhagia alone, an OR of 4.2 was found for the first group (95% CI 2.5-6.8, p <0.001). CONCLUSIONS: This study showed that the probability of malignancy in cases of telorrhagia alone in the Mexican population in a referral hospital is in the high range in relation to the historical world, and is associated with a nodule, the probability is significantly higher.

[Treatment of adamantinoma of femur with limb preservation. A case report and review of the literature]. / Tratamiento de adamantinoma de fémur con preservación de extremidad. Reporte de un caso y revisión de la literatura.

BACKGROUND: Adamantinoma is a rare lesion of low-grade malignancy, and represents 1% of malignant bone tumours of bones, and is mainly located in two regions of the body, jaw (ameloblastoma), and lower extremities. The treatment of choice is surgery due to it being a radio- and chemotherapy-resistant neoplasia. CLINICAL CASE: A 39 year old male with a history of neonatal hydrocephalus with moderate psychomotor retardation. He began with pain in the posterior region of the left thigh for one year before admission, which was managed as posterior radicular syndrome. He had sudden intense pain on walking, that led him to fall over. In the examination, left pelvic limb with deformity in the distal third with increase in volume in the thigh, with pain to palpation, and presence of crackles in the distal third of the femur. A biopsy of the thigh was performed, with subsequent local wide excision + replacement of bone with cadaver bone and a central medullary nail. The final diagnosis was adamantinoma of femur. CONCLUSION: The adamantinomas are rare tumours. It is important to recognise this type of tumor from the beginning, since its prognosis is excellent in initial stages. It is important to have free margins as survival is very high.
