“…2 Studies show that a malignant course may be seen in 15-30% of the cases, with metastatic spread occurring in about 5%. 3 Most distant metastases develop without evidence of local recurrence. The commonest sites for distant metastases are the lung, bone, and abdominal viscera.…”

Cystosarcoma phyllodes was described first in 1838 and originally was considered to be a benign tumor. It was not until 1931 that metastasis from a cystosarcoma phyllodes was reported. The incidence of cystosarcoma phyllodes is estimated to be 0.3% to 0.9% of all breast tumors. Sites most commonly affected by metastases are the lungs and bones. We present a case report 29-year old female patient presented with a voluminous breast mass at both of them which was completely resected. The right side presented of malignant phyllodes and the left side is borderline phyllodes. Six months later, both of her legs became paralyzed and accompanied by swelling over her right upper arm. Biopsy was performed, and the diagnosis was metastatic malignant phyllodes tumor. Histologic review of the breast tumor revealed stromal overgrowth.

Breast lesions with a significant spindle cell or mesenchymal component are not commonly encountered in fine-needle aspiration (FNA) cytologic material and include a heterologous variety of benign and malignant conditions, with phyllodes tumors (PTs) being the foremost differential diagnostic consideration. This study comprises 28 tumors diagnosed histologically as PT in which FNAC material was available for review. Histological sections and cytological smears from these cases were retrieved and subjected to detailed morphological review. Cytological parameters assessed included ratio of stroma to epithelium, pattern characteristics and cytological characteristics of the stromal, and epithelial components and the background cells. Large and hypercellular stroma fragments, dissociated spindle and plump stromal cells, often accompanied by large, folded sheets of epithelium were cytological features that characterized PT. Smears from malignant PT showed predominantly or solely mesenchymal components. FNAC was a highly reliable procedure for the diagnosis of PT, giving an accuracy rate of 92.8%.

Metastases from infraclavicular neoplasms to the oral cavity are rare, and the anatomical structures most frequently affected are the maxillae. The primary sites that develop metastases to head and neck include lung, breast, liver, thyroid gland, kidney and melanomas, among others. The breast is one of the usual primary regions that can present them. In the literature, most metastases to these regions correspond to squamous cell carcinomas and adenocarcinomas; few studies report other type of neoplasms such as phyllodes tumour (PT) that present this behaviour. The importance of identifying metastatic disease to the oral cavity, be it as the first manifestation of a neoplasm from unknown origin or as a development in the course of the disease, is that it allows determination of adequate treatment, which has an effect on the patient's prognosis. The usual behaviour of PT is frequent recurrence and, when metastases are present, these are to lungs and bone. Two cases of malignant PT metastasising to tongue and lip are presented, as well as a review of the literature.
