RESUMEN
Phyllodes tumors are rare biphasic fibroepithelial lesions of the breast and account for 0.3%-0.5% of primary breast tumors. Malignant phyllodes tumor has a 10%-26% risk of distant metastasis. The most common site of metastasis is lungs followed by bone and soft tissue. This is a rare case of a 42-year-old female with a previous history of malignant phyllodes tumor breast. She presented after 10 years with metastases to multiple sites including lung, abdominal wall, retroperitoneum, bone, and brain. These tumors have a poor overall survival. Accurate diagnosis and aggressive management of malignant phyllodes tumors can help in effective treatment at diagnosis and for close follow-up of the patients.

Biphasic squamoid alveolar renal cell carcinoma (BSARCC) is a newly emerging distinct and rare morphologic variant of renal cell carcinoma (RCC). Morphological, immunohistochemical, and molecular data have shown that BSARCC is closely related to papillary RCC type 1. We report a case of Biphasic squamoid alveolar renal cell carcinoma with a rare presentation as cutaneous metastases. This variant tends to show an aggressive behavior. Hence, accurate histopathological diagnosis can help in effective treatment and for close follow-up of the patients.
