Secondary involvement of breasts by follicular lymphoma.

Metastatic lesions involving the breast are exceptional; hematolymphoid neoplasias rank second as per their frequency in case series reported in the literature with a prevalence of 0.04% to 1.6% when considering all malignant breast tumors and reaching an annual incidence of 0.

Dermatofibrosarcoma protuberans with unusual presentation in vulva.

Gynecological sarcomas are rare and their location in the vulva and vagina has an incidence of 5% of all malignant neoplasms in the female genital tract. We present the case of a 54-year-old patient with a diagnosis of dermatofibrosarcoma protuberans in the vulva, an infrequent pathology with less than 60 cases reported worldwide in this anatomical location. Clinically, it is locally aggressive, due to the proliferation of spindle cells with pleomorphism and frequent mitotic figures infiltrating the reticular dermis and subcutaneous cellular tissue, giving rise to variable size tumors with high local recurrence rates.

Renal epidermoid cyst: A case report.

A 56-year-old male patient with no significant clinical history manifested lumbar pain, macroscopic hematuria and dysuria. Radiology images found a renal mass in the upper right pole at the pyelocaliceal level. A partial nephrectomy was performed to resect the tumor, and histology revealed the diagnosis of a renal epidermoid cyst, which is an infrequent lesion with a benign biological behavior.
