Cystosarcoma phyllodes metastatic to the mandible

Imaging of Pelvic Bone Metastasis from Malignant Phyllodes Breast Tumor

The author reports a patient with a malignant phyllodes breast tumor, who then had a ten-year disease free interval before she developed a left pelvic bone metastasis and soft tissue invasion. Cross-sectional and radionuclide imaging of its musculoskeletal metastasis is presented. Literature concerning bone metastasis from phyllodes tumor is also briefly reviewed and discussed, along with its epidemiology.

Phyllodes tumor metastasis to the tonsil with synchronous undifferentiated carcinoma

INTRODUCTION

Breast tumor metastasis to the tonsil is extremely rare.

PRESENTATION OF CASE

A 54-year-old woman underwent resection of a breast malignant phyllodes tumor and later presented with metastasis to the lung and the left tonsil. She underwent left lower lobectomy and resection of the left tonsillar tumor. She subsequently developed undifferentiated carcinoma of the right tonsil. She underwent resection of the right tonsillar tumor and chemotherapy was started. The central venous catheter became infected with methicillin-resistant Staphylococcus aureus. Finally, she died.

DISCUSSION

To the best of our knowledge, this is the first reported case of a phyllodes tumor metastasizing to the tonsil. Furthermore, morphological and immunohistochemical study revealed that the right tonsillar tumor was irrelevant to the phyllodes tumors.

CONCLUSION

We report a case of phyllodes tumor metastasis to the left tonsil which developed undifferentiated carcinoma in the other side of tonsil later. Breast tumor metastasis to the tonsil is rare but it should be considered as a possible diagnosis.

Temporomandibular region metastasis from cystosarcoma phyllodes: a case report and review of the literature

A rare breast tumour (Cystosarcoma phyllodes) in a 58-year-old female metastasizing to the temporomandibular region and infra-temporal fossa, presenting as temporomandibular pain dysfunction syndrome is reported, along with a literature review.

Cystosarcoma Phyllodes Metastatic to the Mandible: Report of a Rare Case and Literature Review

Cystosarcoma phyllodes is a rare breast tumor with variable malignant potential. Metastasis has been reported in a small percentage of cases. We describe the case of a 52-year-old woman who developed a large facial tumor 1 year after she had undergone a mastectomy fora rapidly enlarging breast neoplasm. The facial lesion was found to be a malignant cystosarcoma phyllodes metastatic to the mandible, and the patient died shortly after diagnosis. To our knowledge, this patient represents only the third reported case of a phyllodes tumor metastatic to the mandible.

Malignant phyllodes tumor metastatic to the forearm: a case report

We describe the cytological features of a malignant phyllodes tumor, in a 40-yr-old female, that metastasized to the forearm, and we correlate these findings with the criteria suggested by other authors for predicting the clinical and metastatic behavior of this tumor. The diagnosis of metastasis was based on fine-needle aspiration (FNA) cytology. One year prior, the patient had undergone mastectomy of the left breast for malignant phyllodes tumor, as proven by histopathology. The patient then presented with right forearm swelling, 1 yr later. FNA cytology was performed, and the diagnosis was metastatic malignant phyllodes tumor. Histologic review of the breast tumor revealed stromal overgrowth, which is the most important histologic criterion for predicting the metastatic behavior of malignant phyllodes tumor as reported by some authors.

Mandibular pain as the leading clinical symptom for metastatic disease: nine cases and review of the literature

BACKGROUND

Metastases to the jaws are a rare phenomenon. Nevertheless, the appearance of non-specific symptoms such as toothache can signal the onset of neoplastic disease in some patients.

PATIENTS

In this article, we present details of a 74-year-old patient with a history of breast cancer to illustrate this point. Retrospectively, covering a time span of one year, we could identify nine patients (1.2%) with metastatic disease to the mandible out of a total of 763 patients referred to our Maxillofacial Surgery department with non-specific jaw pain.

RESULTS

Four patients were subsequently diagnosed as having breast cancer, two had lung cancer, one prostate cancer, one renal cell carcinoma and one adenocarcinoma of unknown primary site. Only three of these patients had documented tumor spread to bones before the onset of jaw pain. In the other patients, the dental symptoms were either the first sign of a generalized neoplastic disease, or indicated relapse of disease after long term disease free interval. However, further work up disclosed generalized tumor spread with additional organ- or bone-lesions in all patients, and the median survival was only six months (range 3.5(-)+22) from diagnosis.

CONCLUSION

Pain of uncertain origin in the jaws should alert clinicians to the potential of metastatic disease in patients with a history of cancer and a bone scintigraphy should be done to rule out metastatic involvement. Although metastatic lesions in this area usually herald generalized neoplastic spread according to our experience, prompt diagnosis nevertheless can lead to useful palliation and an enhanced quality of life.

Metastatic tumors to the jawbones: analysis of 390 cases

A review of the English language literature revealed 390 well-documented cases of metastatic lesions to the jawbones. Most metastatic lesions were diagnosed in patients in their fifth to seventh decade. The primary site differed between the genders: for women, it was the breast followed by the adrenal, colo-rectum, female genital organs and thyroid; for men, it was the lung, followed by the prostate, kidney, bone and adrenal. The most common location of the metastatic tumors was the mandible, with the molar area the most frequent site involved. In about 30% of cases the oral lesion was the first sign of the malignant disease. The present data are compared with those of metastatic tumors to the oral mucosa and a view on the possible pathogenesis is presented.

Central nervous system complications of cystosarcoma phyllodes

BACKGROUND

Cystosarcoma phyllodes (CP) is an uncommon fibroepithelial breast neoplasm that rarely involves the central nervous system (CNS).

METHODS

The authors encountered two patients with CNS metastases and reviewed the literature to identify reports of CP affecting the nervous system. Patients must have been reported in sufficient detail to characterize clinical course, extent of tumor burden, and histologic type of the primary tumor and metastasis to be included in the study.

RESULTS

Eleven cases were identified from the literature, but only six were presented in sufficient detail for analysis. Including the current patients, the mean age of patients with CP metastases was 52 years. The time between initial diagnosis and CNS involvement was 5 years. Parenchymal brain metastases respond poorly to treatment, with a mean survival of 29 days, whereas survival is significantly longer with CNS involvement secondary to epidural extension of tumor from adjacent bony structures. Local recurrence or widespread metastases nearly always were present at the time of CNS involvement.

CONCLUSIONS

Brain metastases from CP are refractory to therapy and carry a dismal prognosis. Patients with CP and brain metastases should undergo brain biopsy to exclude metastases from associated epithelial breast tumors, which have significantly better prognoses. Patients with compressive lesions arising from bone have a better prognosis and may benefit from aggressive management.
