RESUMO
O carcinoma rico em glicogênio da mama é uma variante rara de carcinoma ductal infiltrativo. Clinicamente, não difere de outros tipos de carcinoma mamário. Relatamos um caso de paciente de 56 anos, com nódulo não-palpável de mama direita, cujo diagnóstico por biópsia foi de carcinoma de células claras da mama. Posteriormente, a paciente foi submetida a setorectomia com biópsia do linfonodo sentinela. Como apresentava receptores de estrógeno e progesterona positivos, optou-se por radioterapia e hormonoterapia como tratamento adjuvante. De história pregressa, há cinco anos, a paciente havia sido submetida a nefrectomia por carcinoma renal, diagnosticado à época como carcinoma de células claras, sugerindo que o tumor mamário atual fosse de natureza metastática, hipótese afastada por estudo imunoistoquímico. A revisão do tumor renal, no entanto, mostrou tratar-se de carcinoma de células cromófobas do rim, variante de prognóstico favorável e sem potencial metastático.
ABSTRACT
The glycogen-rich carcinoma of the breast is an uncommon type of ductal invasive carcinoma. Its clinical presentation does not differ from other types of invasive carcinoma of the breast. Herein, we report a case of a 56-year old woman presenting with a nonpalpable nodule in the right breast whose biopsy diagnosis was glicogen-rich clear-cell carcinoma. A lumpectomy was performed later on with sentinel lymph node biopsy. As it expressed estrogen and progesterone receptors, radiotherapy and hormoniotherapy were given as adjuvant treatment. Of interest, 5 years ago, the patient had been underwent a nephrectomy due to a renal carcinoma diagnosed as clear-cell carcinoma of the kidney raising the suspect that the breast tumor might be a metastase. This hypothesis, however, was eliminated by immunohistochemistry. Moreover, the review of the slides of the renal tumor showed a cromophobe-cell carcinoma, a variant associated with favorable prognosis and no metastatic potential.
