[Dermatomyositis and rectal cancer: case study and literature review]. / Dermatomyosite et cancer rectal: à propos d'un cas avec revue de la littérature.

Dermatomyositis is a systemic idiopathic disease characterized by a combination of both muscle and skin symptoms. It is a paraneoplastic dermatosis. Its association with rectal cancer has been rarely described in the literature. We here report the case of a female patient with paraneoplastic dermatomyositis associated with metastatic rectal adenocarcinoma presenting with clinical symptoms commonly found in subjects with paraneoplastic dermatomyositis. Other complementary examinations (CPK test + EMG + skin biopsy) were performed which confirmed this diagnosis. The patient underwent chemotherapy, but after the second cycle, she experienced a rapid worsening of her general condition and died after some days in a state of multisystem organ failure. This study aims to highlight paraneoplastic dermatomyositis' aggressive nature and to update current knowledge on the importance of chemotherapy in the management of neoplastic dermatomyositis.

[Outcome of locally advanced Darier and Ferrand dermatofibrosarcoma: about a case and literature review]. / Une réponse complète d'un dermatofibrosarcome de Darrier et Ferrand localement avancé: à propos d'un cas et revue de la littérature.

Darier and Ferrand dermatofibrosarcoma (DFS) is a rare skin tumor characterized by its local aggressiveness and a high risk of recurrences. Prognosis depends essentially on the quality of treatment. Complete response in Darier and Ferrand dermatofibrosarcoma with healthy margins, initially judged inoperable after 1 year of neoadjuvant imatinib-based treatment, has been rarely described in literature. We here report the case of a young female patient treated in the Department of Medical Oncology in FES for locally advanced DFS with complete response, in order to assess the role of imatinib and of targeted therapies in the treatment of DFS.

[Neuroendocrine carcinoma of the cervix: a case report and review of the literature]. / Carcinome neuroendocrine du col utérin: à propos d'un cas avec revue de la littérature.

Small cell neuroendocrine carcinomas of the gynecologic tract are unusual, accounting for only 2% of the cervical cancers. Given the rarity of these tumors and the absence of randomized trials, their diagnosis and treatment programmes are difficult and are essentially based on those of neuroendocrine tumors of the lung. As in the case of the neuroendocrine tumors of the lung and despite multimodal treatment they are associated with a poor prognosis. We here report a new case of small cell neuroendocrine carcinoma of the cervix and, throught a literature review, we highlight the various aspects of this rare entity.

[Pleural epithelioid sarcoma: about a case and review of the literature]. / Sarcome épithélioide pleural, à propos d'un cas avec revue de la littérature.

Proximal epithelioid sarcoma (PES) originating from the pleura is a clinical entity rarely reported in the literature. We report the case of a young patient with immediately metastatic proximal epithelioid sarcoma (PES) treated at the Department of Medical Oncology, Fes. Treatment consisted of chemotherapy based on doxorubicin and ifosfamide. After the first cycle of chemotherapy, the disease led to a fatal outcome. Our case study highlights the potentially aggressive behaviour of PES which represents a clinical trap and can be life-threatening.
