Enfermedad de Kimura en paciente no asiática / Kimura’s disease in a non-asian patient

La enfermedad de Kimura es un trastorno inflamatorio benigno poco frecuente, de etiología desconocida y que afecta principalmente a sujetos de origen asiático. Clínicamente se manifiesta como masas subcutáneas, indoloras, sobre todo en la zona de cabeza y el cuello. Suele acompañarse de linfadenopatías, y aumento de los niveles de eosinófilos e IgE en sangre periférica. Se presenta un caso de enfermedad de Kimura, diagnosticado en una mujer caucásica tras la exéresis-biopsia de una masa mandibular de gran tamaño. Describir esta patología ayudará a incluir la misma en el diagnóstico diferencial de masas, sobre todo a nivel cervico-facial, favoreciendo así su adecuado manejo diagnóstico-terapéutico. (AU)

Kimura’s disease is a rare benign inflammatory disorder of unknown etiology that mainly affects individuals of Asian origin. Clinically it manifests as subcutaneous, painless masses, especially in the head and neck area. It is usually accompanied by lymphadenopathies and an increase in eosinophil and IgE levels in peripheral blood. A case of Kimura’s disease is presented, diagnosed in a Caucasian woman after the excision-biopsy of a large mandibular mass. Describing this pathology will help to include it in the differential diagnosis of masses, especially at the cervico-facial area, thus favoring its adequate diagnostic-therapeutic management. (AU)

Oncological outcomes of lipofilling in breast reconstruction: a matched cohort study with 250 patients.

BACKGROUND: Fat grafting is a procedure commonly used in breast reconstruction nowadays. Nevertheless, its oncological safety remains controversial. The potential risk that progenitor cells included in fat graft tissue may contribute to disease progression in patients with breast cancer is still debatable. We have designed a matching-cohort study with 250 patients with history of breast cancer trying to elucidate an answer for this question. METHODS: We selected 250 patients with a history of breast cancer in our hospital, between 2011 and 2019. A total of 125 patients (cases) had a history of breast cancer reconstructed with fat grafting. The additional 125 patients are matched controls. We analyzed the distribution of eight different variables within the cases and their matched controls: date of first oncological surgery, age, type of oncological surgery, histological subtype, Her-2 status, pN, smoking habit and diabetes mellitus. The objective of this study was to analyze the influence of fat grafting over breast cancer recurrence. RESULTS: There are not statistically significant differences in breast cancer locoregional recurrences (P=0.183), distant metastases (P=0.200) or total recurrences (P=0.065) amongst the two groups (cancer cases and matched controls). CONCLUSIONS: Our study adds more information over the oncological safety of fat grafting. These findings should encourage long-term prospective trials to provide surgeons with accurate information regarding the role of lipofilling on breast neoplasms.
