Reconstructing Ear Defects Using the Revolving Door Island Flap: A Case Series. / Reconstrucción de defectos auriculares mediante el «colgajo en isla en puerta giratoria¼. Serie de casos.

BACKGROUND AND OBJECTIVES: Defects of the anterior region of the pinna pose a reconstruction challenge owing to the complex topography and difficult access. We report our experience using the revolving door island flap (RDIF) to reconstruct pinna defects and present the surgical results. MATERIAL AND METHODS: Retrospective descriptive study of patients undergoing ear reconstruction using RDIF at different sites of the anterior region after resection of malignant tumors. RESULTS: Seventeen patients underwent surgery between 2011 and 2019 for squamous cell carcinoma (n=7) and basal cell carcinoma (n=10). Conventional histology showed disease-free surgical margins in all the resected tissue specimens. The mean follow-up period was 40 months. One local recurrence of squamous cell carcinoma was observed, which responded well to radiation therapy; all patients were free of disease at the end of follow-up. Only 3 patients presented minor complications (depression of the flap surface in 1 case and retraction of the ear toward the mastoid process in 2 cases). Subjective rating scales were used to evaluate cosmetic and functional outcomes as assessed by both the dermatologist and the patient. The normal contour of the pinna was conserved in all patients and no patients required additional corrective surgery. CONCLUSIONS: Reconstruction of the pinna using RDIF allowed for satisfactory repair following complete resection of the tumors, while conserving structure and functionality. RDIF has been reported to be a very good option for reconstruction of the pinna. It is a simple technique that makes it possible to repair large defects with minimal risk of necrosis. In our series, the cosmetic results were excellent and recurrence rates were very low. RDIF provided optimal results in repairing lesions in the concha and in other regions, such as the antihelix, triangular fossa, and scapha.

Carcinoma en coraza por cáncer de mama 17 años después / Carcinoma en cuirasse from breast cancer 17 years later

Resumen Caso clínico: paciente de 73 años de edad, con diagnóstico de adenocarcinoma ductal infiltrante en la mama izquierda. Se trató con mastectomía total, linfadenectomía axilar y quimioterapia. Diez años después le aparecieron un linfedema en el brazo izquierdo y hombro congelado. El linfedema estaba muy indurado y eritematoso, con numerosas lesiones costrosas y sobreinfectadas. La biopsia cutánea mostró infiltración neoplásica debida al carcinoma mamario y reporte de aumento de Ca 15.3. En el escáner cérvico-tóraco-abdomino-pélvico se observó derrame pleural izquierdo masivo, con atelectasia pulmonar subyacente y múltiples erosiones óseas, compatible con afectación tumoral. Tras recibir quimioterapia paliativa disminuyó temporalmente la infiltración cutánea tumoral. Conclusión: el carcinoma mamario es uno de principales cánceres que afectan a la mujer. Sus metástasis cutáneas son del orden de 37% a 5 años. El carcinoma en coraza es una variedad excepcional (3%), de evolución lenta, sin daño sistémico. Las pacientes con cáncer de mama deben tener un seguimiento estrecho postmastectomía y ante la sospecha de metástasis cutánea, diagnosticarla oportunamente para ofrecerles la opción del tratamiento temprano.

Abstract Clinical case: patient of 73 years of age, with diagnosis of infiltrating ductal adenocarcinoma in the left breast in 2004; it was treated with total mastectomy, axillary lymphadenectomy and chemotherapy; 10 years later, she had induration and erythema in the mastectomy area, with some superficial necrotic lesions and cutaneous infiltration to the right breast. In the left arm: indurated lymphedema, with numerous crusted, superficial and superinfected lesions. The skin biopsy showed neoplastic infiltration due to mammary carcinoma and an increase in Ca 15.3. In the cervico-thoraco-abdominal-pelvic scan, massive left pleural effusion was observed, with underlying pulmonary atelectasis and multiple bone erosions, compatible with tumor involvement. After receiving palliative chemotherapy, the cutaneous infiltration of the tumor decreased temporarily. Conclusion: mammary carcinoma is one of the main cancers that affect women. Their cutaneous metastases are of the order of 37% at 5 years. Cutaneous carcinoma is an exceptional variety (3%), of slow evolution, without systemic damage. Patients with breast cancer should have a close postmastectomy follow-up and, in case of skin metastasis suspicion, diagnose it in a timely manner to offer them the option of early treatment.
