[Which chemotherapy regimen in patients with metastatic phyllodes tumors of the breast? case report]. / Quelle chimiothérapie dans les tumeurs phyllodes métastatiques du sein? rapport de cas.

Phyllodes tumors (PT) of the breast are rare. They can be benign, borderline or malignant. Malignant forms account for 20-30% of PTs, with distant metastases in 10-26% of cases. Chemotherapy is one of the main therapeutic weapons for metastatic phyllodes tumors (MPTs). We here report four cases of MPTs of the breast managed at The Mohammed VI Center For Cancers Treatment in Casablanca from January 2015 to December 2017. The average age of patients ranged from 25 to 45 years. The mode of revelation was represented, in the majority of cases, by the occurrence of a huge breast mass and in all patients the histological diagnosis was based on the examination of mastectomy specimen. Three patients had lung metastases, two had axillary lymph-node metastases, two had bone metastases and only one had liver metastases. All patients received chemotherapy. Doxorubicin monotherapy and doxorubicin-ifosfamide (AI) were used. Only one patient had a very favorable outcome, with radiologic complete response after 3 AI regimens. MPTs of the breast have a poor prognosis. The role of systemic chemotherapy is to be defined, especially since there are no data available on optimal chemotherapy regimen.

Paraneoplastic dermatomyositis revealing undifferentiated nasopharyngeal carcinoma at early stage: a case report.

CONTEXT: Dermatomyositis is a rare autoimmune disease characterized by noninfectious inflammatory damage of skin and predominant muscles in the belts. It is believed to be associated with about 1 in 1000 cases of nasopharyngeal carcinoma. This association has been described for locally advanced stages II and III nasopharyngeal carcinoma. It has rarely been described in the early stages (stage I). CASE PRESENTATION: A 65-year-old Moroccan patient residing in Casablanca, with no particular history was referred to the Mohamed VI Center for the treatment of cancers of the University Hospital Center IBN ROCHD in Casablanca, for treatment of nasopharyngeal cancer. He was admitted in poor general condition, performance status 3, with erythema on the face, neck, and extremities. The diagnosis of paraneoplastic dermatomyositis was made owing to progressive muscle weakness and elevation of muscle enzymes associated with the typical rash of the face and hands. He received corticosteroid therapy and then radiotherapy to the nasopharynx with good clinical outcome, disappearance of skin lesions, and recovery of muscle strength. CONCLUSIONS: We report this case of dermatomyositis in early-stage nasopharyngeal carcinoma, which is a rarely described entity. Rapid treatment of dermatomyositis improved the patient's quality of life and enabled him to support specific cancer treatments. This can be used as an element of early diagnosis and monitoring after treatment.
