RESUMO
Resumen ANTECEDENTES: La afectación mamaria por un linfoma es poco frecuente; casi siempre se trata de linfomas tipo B que se caracterizan por falta de especificidad clínica y radiológica, lo que dificulta el diagnóstico diferencial con tumoraciones mamarias de otro origen. CASO CLÍNICO: Paciente de 72 años de edad, con antecedentes de hipercolesterolemia, hipertensión arterial, artrosis y depresión, con dos partos y menopausia a los 55 años. Madre con antecedente de cáncer de mama posmenopáusico. En la mamografía de la mama derecha se encontró una masa retroareolar de 8 cm, de contornos mal definidos y una adenopatía axilar con engrosamiento cortical. La biopsia reportó un linfoma no Hodgkin B de alto grado. Se administraron 8 ciclos de quimioterapia con el esquema R-CHOP. Luego de este esquema el PET-TC mostró una lesión mamaria derecha residual, metabólicamente inactiva, sin enfermedad nodal ni extramamaria supra ni infradiafragmática. CONCLUSIONES: Una neoplasia maligna mamaria no siempre se trata de un carcinoma ductal o lobulillar. Es necesario valorar la posibilidad de otras estirpes histológicas o, incluso, de una afectación metastásica. La entrevista y exploración adecuadas son fundamentales para una buena orientación diagnóstica.
Abstract BACKGROUND: The mammary affectation by a lymphoma is not frequent; it almost always involves type B lymphomas. It is characterized by a lack of clinical and radiological specificity, which makes differential diagnosis difficult with mammary tumors of another origin. CLINICAL CASE: A 72-year-old patient with a history of hypercholesterolemia, hypertension, osteoarthritis and depression, with two deliveries and menopause at 55 years of age. Mother with a history of postmenopausal breast cancer. The mammography of the right breast reported the existence of a retroareolar mass of 8 cm, of ill-defined contours and an axillary adenopathy with cortical thickening. The biopsy reported a high-grade non-Hodgkin B lymphoma. 8 cycles of chemotherapy were administered with the R-CHOP scheme. After this procedure, the PET-CT showed a residual, metabolically inactive right mammary lesion, with nodal or extramammary supra or infradiaphragmatic disease. CONCLUSIONS: A malignant mammary neoplasm is not always a ductal or lobular carcinoma. It is necessary to evaluate the possibility of other histological strains or, even, of a metastatic affectation. The adequate interview and exploration are fundamental for a good diagnostic orientation.
RESUMO
Cervical cancer in virgin women is extremely rare. We present the case of a 36-year-old patient without any type of sexual contact with sensa- tion of lump in external genitalia referring only irregular bleeding in the previous two months, finding in vaginal examination an indurated mass in vaginal introitus with result in the biopsy of adenosquamous adenocarcinoma. The evolution of the tumor was very aggressive in spite of trying palliative chemotherapy, and patient died two months after of diagnosis with lung, liver and brain metastases. Cervical human papil- lomavirus testing was negative. What unusual of these cases does not justify the cytology as the only method of screening for cervical cancer.
