ABSTRACT
BACKGROUND: Breast cancer remains the most commonly diagnosed cancer in women. Breast-conserving surgery (BCS) is the standard approach for small low-risk tumors. If the efficacy of cryoablation is demonstrated, it could provide a minimally invasive alternative to surgery. PURPOSE: To determine the success of ultrasound-guided cryoablation in achieving the absence of Residual Invasive Cancer (RIC) for patients with ER + /HER2- tumors ≤ 2cm and sonographically negative axillary nodes. MATERIALS AND METHODS: This prospective study was carried out from April 2021 to June 2023, and involved 60 preoperative cryoablation procedures on ultrasound-visible, node-negative (cN0) infiltrating ductal carcinomas (IDC). Standard diagnostic imaging included mammography and tomosynthesis, supplemented by ultrasound-guided biopsy. MRI was performed in patients with associated intraductal carcinoma (DCIS) and an invasive component on core needle biopsy (18 out of 22 cases). All tumors were tagged with ferromagnetic seeds. A triple-phase protocol (freezing-thawing-freezing) with Argon was used, with an average procedure duration of 40 min. A logistic regression model was applied to determine significant correlation between RIC and the study variables. RESULTS: Fifty-nine women (mean age 63 ± 8 years) with sixty low-risk unifocal IDC underwent cryoablation prior to surgery. Pathological examination of lumpectomy specimens post-cryoablation revealed RIC in only one of 38 patients with pure IDC and in 4 of 22 mixed IDC/DCIS cases. All treated tumors had clear surgical margins, with no significant procedural complications. CONCLUSIONS: Cryoablation was effective in eradicating 97% of pure infiltrating ER + /HER2-tumors ≤ 2cm, demonstrating its potential as a surgical alternative in selected patients.

BACKGROUND: Primary systemic therapy (PST) has acquired great importance in breast cancer (BC) in the last few years. In this scenario, even if it is accepted to perform SLNB before PST, most of the guidelines remark the advantages of this practice after it, such as avoiding another surgery to the patient, a rapid start of the treatment and no need of axillary dissection in cases of pathologic complete response (pCR). Nevertheless, the lack of knowledge of the initial axillary state and the need to practice axillary dissection with any axillary disease are claimed to be some other disadvantages. There are no randomized studies yet that can conclude the optimal timing of SLNB in PST, so for the moment we may settle for our common practice. PATIENTS AND METHODS: We studied all the cases attended in the Breast Unit that joined the inclusion criteria between 2011 and 2019 in our hospital and we compared the group with SLNB before PST with the group with SLNB after PST in terms of unnecessary axillary dissection and description features. RESULTS: We included 223 female patients diagnosed with BC and without clinical nor radiological axillary disease (cN0), who had received NAC and SLNB performed before or after it. We observed a higher proportion of high-grade histological tumors (G3), tumors with aggressive phenotypes (Basal like and Her 2 enriched), and younger women in the group of SLNB before NAC compared with the SLNB after NAC group (P < .01). Despite this, we did not find any difference in the number of positive SLNBs or in the number of ALND performed between the 2 groups. We found a higher proportion of ALND with all the lymph node (LN) negatives in the SLNB before NAC group. CONCLUSION: Taking into account that in the observation period we did not use ACOSOG Z0011 criteria with all the SLNBs, we figure out what would have been the real results nowadays following these criteria. In this scenario we conclude that patients with luminal phenotype seemed to benefit from practicing SLNB before NAC in terms of avoiding axillary dissections. We could not make any conclusion in the rest of the phenotypes. However, prospective studies are needed to confirm if this affirmation could be proved.

El plasmocitoma mamario es una neoplasia de células plasmáticas extremadamente infrecuente, con menos de cincuenta casos descritos en el último siglo. Por este motivo, apenas se dispone de datos acerca del abordaje, tratamiento y seguimiento más convenientes. Presentamos el caso de una paciente de 70 años que debutó con un plasmocitoma mamario y que un año después fue diagnosticada de un carcinoma mamario lobulillar ipsilateral. La asociación entre plasmocitoma y cáncer de mama no está descrita en la literatura, por lo que es muy complicado establecer un vínculo entre ambas entidades. Sin embargo, el abordaje terapéutico del plasmocitoma podría comprometer el tratamiento ulterior de un cáncer de mama, por lo que el tratamiento idóneo en estos casos sea probablemente la cirugía.
Breast plasmocytoma is an extremely rare plasma cell neoplasm, with less than 50 cases reported in the last century. This is the reason why we barely have data about optimal management, treatment and follow-up. We hereby report the case of a 70 year old woman diagnosed with breast plasmocytoma that developed lobular breast cancer a year later. The link between plasmocytoma and breast cancer has not been previously established. However, breast plasmocytoma treatment could compromise latter breast cancer approach, so probably the most suitable strategy in these cases should be breast surgery.Conclusions: There are clinical characteristics associated with complications in women with surgical management abortion in our center, such as admission diagnosis, unplanned pregnancy, previous abortion and type of evacuation. There are limitations regarding the quantity and quality of information, however, our results allow us to know the profile of patients treated for abortion in our center.

RESUMEN Introducción y objetivos: La fibromatosis produce tumores benignos pero localmente agresivos, que afectan a los tejidos blandos. A nivel mamario, representa tan sólo el 0.2% de las neoplasias de la mama. Nuestro objetivo con el presente artículo es profundizar en el conocimiento de la fibromatosis mamaria, a través del estudio de dos casos clínicos, mostrando sus características clínico-radiológicas e histológicas, e intentar establecer un protocolo de actuación adecuado. Métodos: Estudio retrospectivo de dos casos clínicos de fibromatosis mamaria diagnosticados en el Hospital Universitario La Paz entre los años 2018 y 2019. Resultados: Presentaremos dos pacientes con diagnóstico de fibromatosis mamaria, ambas debutaron con la autopalpación de un nódulo mamario. Al realizarles una ecografía, se visualizó un nódulo sólido, mal definido y axila ecográficamente negativa, que precisó de biopsia-aspiración con aguja gruesa. En los dos casos, se decidió resección quirúrgica de la lesión. Seguimiento mediante exploración mamaria y pruebas de imagen periódicas. Conclusiones: Aunque se trata de una entidad benigna, la fibromatosis mamaria puede simular un proceso maligno, tanto clínica como radiológicamente, por lo que precisa de un estudio histológico. A pesar de que la diseminación metastásica es muy poco frecuente, no se debe olvidar el carácter agresivo a nivel local de esta patología, y sus altas tasas de recurrencia. Como tratamiento, se debe realizar una resección quirúrgica, aunque recientemente se ha contemplado la opción de vigilancia estrecha sin tratamiento. No existe evidencia científica que justifique la utilización de otros tratamientos como la radioterapia o el tratamiento hormonal.
ABSTRACT Introduction and objectives: Fibromatosis produces benign but locally aggressive tumours that affect soft tissues. At breast level, it represents only 0.2% of breast neoplasms. Our goal with this article is to increase knowledge on breast fibromatosis, through the study of two clinical cases; explaining their clinical-radiologic and histological characteristics. Additionally, try to establish an adequate protocol, for the management of the disease and for its subsequent monitoring. Methods: A retrospective study about two clinical cases of breast fibromatosis diagnosed in La Paz Hospital between 2018-2019. Results: both patients presented with clinical manifestations, autopalpation of a breast nodule. A breast ultrasound was performed and a solid nodule was visualized, with poorly defined edges and ecographically negative armpit. A core needle biopsy was performed to confirm the histological diagnosis. In both clinical cases, the treatment was surgical resection of the lesion. Periodic revisions are being performed in order to exclude recurrence. Conclusions: Although it is a benign disease, breast fibromatosis can simulate a malignancy, both in a clinical and radiological way, so histological study is mandatory in order to achieve an accurate diagnosis. Even metastatic dissemination is extremely rare, the local aggressive nature and high rates of recurrence for fibromatosis makes surgical excision, with wide free margins, the most important tool in treatment, although the possibility of close surveillance without treatment is recently being contemplated. There is no scientific evidence to justify the use of other treatments such as radiotherapy or hormonal treatment.

Resumen ANTECEDENTES: Los tumores vaginales benignos son excepcionales: papilomas, hemangiomas, pólipos y leiomiomas. Estos últimos son los más raros (4-5% de todas las neoplasias vaginales) pues solo se han reportado alrededor de 300 casos. CASO CLÍNICO: Paciente de 47 años, acudió a la consulta ginecológica con una tumoración vaginal de dos meses de evolución, sin manifestaciones clínicas adicionales. En la exploración física se observó una tumoración elástica, en la cara posterolateral derecha de la vagina. La ecografía transvaginal no mostró la alteración. Después del tratamiento expectante inicial, en la siguiente revisión se comprobó el rápido crecimiento de la lesión y la manifestación de los síntomas vaginales. Se decidió la extirpación quirúrgica de la lesión. El estudio anatomopatológico reportó un leiomioma vaginal, con células con núcleos atípicos. Durante el seguimiento la paciente permaneció asintomática, sin signos de recidiva local. CONCLUSIÓN: Si bien los leiomiomas son los tumores benignos más frecuentes en mujeres en edad reproductiva, su manifestación vaginal es excepcional. El diagnóstico definitivo se establece en el estudio anatomopatológico y el tratamiento de elección es la extirpación quirúrgica completa. Los tumores con elevada celularidad, alta concentración de células atípicas y actividad mitótica incrementada pueden tener un comportamiento benigno. Las recidivas también son excepcionales.
Abstract BACKGROUND: Benign vaginal tumors are a very rare entity which includes papillomas, hemangiomas, polyps and leiomyomas. Leiomyomas are especially infrequent, constituting only 4-5% of all vaginal tumors. In literature, about 300 cases have been reported. CLINICAL CASE: 47-year-old patient, who attended a gynecological consultation with a vaginal tumor of two months evolution, without additional clinical manifestations. Physical examination refers to an elastic tumor on the right posterolateral aspect of the vagina. The transvaginal ultrasound did not show the alteration. After the initial expected treatment, in the following review the rapid growth of the lesion was observed, in addition to the manifestation of vaginal symptoms. Surgical removal of the lesion will be applied. The anatomopathological study reported a vaginal leiomyoma, and cells with bizarre nuclei. During the follow-up, the asymptomatic patient was observed, without signs of local recurrence. CONCLUSION: Although leiomyomas represent the most frequent benign tumors in women of reproductive age, their vaginal manifestation is exceptional. The gold treatment is complete surgical extirpation and the definitive diagnosis is established by anatomopathological study. Tumors with high cellularity, high concentration of bizarre cells and increased mitotic activity appear to have a benign behavior. Although it is rare, there are cases of recurrence.
ABSTRACT
This article examines the clinical presentation of ocular metastasis from an infiltrating lobular breast carcinoma. We examined a conjunctival biopsy from a 69-year-old woman who developed unilateral conjunctival inflammation together with a neurotrophic corneal ulcer and proptosis. Infiltrating lobular breast carcinoma (ILBC) was diagnosed using routine histology and immunohistochemistry. She had a past history of a hormone receptor-positive infiltrating ILBC 11 years ago with cutaneous and diffuse osteoblastic metastases, and she was kept under treatment with lezotrol. Treatment was initiated with systemic corticosteroids but an annular conjunctival perilimbal infiltration was found to have spread, which did not respond either to local radiotherapy (total dose 60 Gy, 2 Gy per day). A new extensive corneal epithelial defect recurred, and because it had not responded to matrix therapy agent (RGTA, Cacicol®) eye drops, autologous serum eye drops and a therapeutic contact lens, a permanent total tarsorrhaphy was performed. Progression of the diffuse bone metastases was detected and the treatment with lezotrol was replaced by fulvestrant.Infiltrating lobular breast carcinoma is a rare cause of conjunctival metastasis. This aggressive malignancy did not respond to external beam radiotherapy.
