Nonleukemic Granulocytic Sarcoma of Knee: A Case Report

Granulocytic sarcoma (GS) is a rare extramedullary tumor composed of immature myeloid cells. It is usually associated with leukemia or other myeloproliferative disorders. It occurs very rarely without overt hematologic diseases. A 19-year-old man presented with left knee mass. Biopsy with pathological analysis showed lymphoma aspect. Immunostains yielded the diagnosis of GS with myeloperoxidase and CD43 positivity. There was no systemic manifestation of leukemia, and bone marrow biopsiy was negative for neoplastic infiltration. Chemotherapy by CHOP was efficient, and the patient remaind alive and healthy 40 months after the end of treatment. The case is discussed in the framework of the existing literature about the diagnosis, treatment, and prognosis of this very rare condition

Reduction in HER-2 protein expression in a breast tumor HER-2 positive after only one injection of Trastuzumab: a case report

HER-2 is overexpressed in 20 to 30% of breast cancer. Generally, metastases of a breast tumor have the same HER-2 status, although some discordances were reported

Ovarian cancer revealed by paraneoplastic cerebellar degeneration: a case report

The prevalence of paraneoplastic cerebellar degeneration (PCD) associated with gynecological cancer is rare. Here, we reported the first case of ovarian cancer revealed by PCD in our institute. we describe a 80- year –old  Moroccan female presented with subacute vestibular and cerebellar syndromes, she had an inguinal  lymphadenopathy,with high levels of Anti-YO. Rapid progression and absence of known etiologies point   towards a probable paraneoplastic origin of the syndrome in this patient. The exact incidence of PNS among   those diagnosed with cancer remains uncertain, it is important to report this cases in the literature to help  early diagnosis and appropriate treatment, which are able to stabilize the neurological symptoms.Key words: Paraneoplastic cerebellar degeneration, Paraneoplastic syndromes, ovarian cance

Lipoblastome de la fosse sous temporale

Le lipoblastome est une tumeur bénigne rare, formée d'adypocytes immatures associés à la présence d'une matrice myxoide, de septas fibreux, et d'une architecture lobulaire. Il survient généralement chez le nourrisson et l'enfant. Cette tumeur touche dans la majorité des cas les tissus sous-cutanés des extrémités et du tronc. Elle est extrêmement rare au niveau de la tête et du cou. Un total de moins de 100 cas ont été rapportés précédemment dans la littérature

<p>Abstract</p> <p>Introduction</p> <p>Malignant transformation is a rare complication of mature cystic teratoma with squamous cell carcinoma being the most common type. We report a new case of squamous cell carcinoma in situ.</p> <p>Case presentation</p> <p>A 62 year old woman was admitted for an abdomino-pelvic mass and she underwent a left salpingo-oophorectomy.

Une métastase intra-thyroïdienne révélant un cancer bronchique non à petites cellules

Les métastases thyroïdiennes sont très peu fréquentes. Elles peuvent de façon exceptionnelle révéler le cancer primitif. Nous rapportons le cas d'une patiente qui a présenté une dysphonie secondaire à un gros nodule  thyroïdien lobaire droit. L'examen anatomopathologique de la pièce de l'hémi thyroïdectomie a révélé la  présence d'un adénocarcinome d'origine pulmonaire. Le bilan d'extension a confirmé la présence d'une masse au niveau du Fowler droit ainsi qu'une métastase du trochanter fémoral droit et une récidive au niveau de la loge thyroïdienne. Une chimiothérapie à base de Paclitaxel, Carboplatine et Bevacizumab a été débuté.  L'évaluation après 4 cures est en faveur d'une stabilité radiologique avec amélioration des symptômes.Key words: Métastase intra-thyroïdienne, cancer bronchique, dysphoni

Unusual case of cavitary lung metastasis from squamous cell carcinoma of the uterine cervix

Spontaneous excavation of primary lung cancer is common; however cavitation of metastatic lung lesions is rare and usually confused with benign lesions. In Moroccan context tuberculosis is the first suspected diagnosis of lung excavations. We report a rare case of cavitary lung metastasis of a uterine cervix cancer, treated initially as tuberculosis. A 40-year old non-smoking woman with a known history of squamous cell carcinoma of the uterine cervix since August 2005; presented on September 2008 with right chest pain without fever, hemoptysis or weight loss. CT scan showed a thin walled cavity. Empirical Antibiotic therapy was conducted 15 days with poor outcome. Then antibacillary treatment was started with no proof of mycobacterial infection. A month later, the patient presented with gynecological bleeding and a pneumothorax. Bronchoscopy with transbronchial biopsy of the cavitary mass was performed. Pathology demonstrated a metastatic squamous cell carcinoma. Pelvic examination and MRI showed a subsequent local cervix recurrence. Patient underwent 3 courses of systemic chemotherapy. She died on June 2009 due to progressive disease. Even cavitary lung metastases are rare and benign differential diagnosis are more common, clinician should be careful in neoplastic context and investigation should be done to eliminate a recurrence.Pan African Medical Journal 2013; 14:3

Radiation induced esophageal adenocarcinoma in a woman previously treated for breast cancer and renal cell carcinoma

BACKGROUND: Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. CASE PRESENTATION: A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. CONCLUSION: We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders

Liposarcome dédifférencie du cordon spermatique: difficultés thérapeutiques des grosses tumeurs

Le liposarcome du cordon spermatique est une entité rare : environ 100 cas ont été rapportés dans la littérature. Nous rapportons l’observation d’un homme âgé de 42 ans, chez qui a été décelée une masse tumorale développée aux dépens du cordon spermatique droit. Une orchidectomie droite avec exérèse large de la tumeur a été difficilement réalisée en raison de la taille importante de la masse. En post opératoire, le patient a présenté une progression locale et métastatique pulmonaire. Une mono chimiothérapie a été administrée à base d’anthracycline mais le patient a décédé suite à une progression rapide de la maladie. À travers cette observation, nous rapportons brièvement les données de la littérature de cette entité rare. Une exérèse large avec des marges saines, tant que possible, est indispensable pour le contrôle local de la maladie. Néanmoins, en cas de taille tumoral importante, comme le cas de notre patient, une exérèse complète est souvent difficile. Vu le taux élevé de rechute locale, une stratégie combinée associant chirurgie et radiothérapie adjuvante peut être envisagée. Le rôle de la chimiothérapie, bien qu’incertain, garde son indication dans les cas métastatiques, surtout dans les sous types dédifférenciés
