Metaplastic breast carcinoma is defined as a heterogeneous group of invasive breast cancercharacterized by differentiation of the neoplastic epithelium into squamous or mesenchymalcells with differentiation into spindle, chondroid, bone or other cells. It is a rare malignanttumor that represents lessthan 1% of breast cancers. It is an aggressive tumor, with a poorprognosis and resistant to chemotherapy.We report a case of metaplastic breast carcinoma, in order to discuss the epidemiological,clinical and histopathological particularities with a review of the literature.This caseconcerned a52-year-old woman with a nodule in the upper outer quadrant of the right breast,with a history of excision of a cystic papilloma on the same site, classified ACR4 onmammography. Histological and immunohistochemical examinationhad concludedametaplastic carcinoma.
Hodgkin disease is a malignant pathology of lymphatic system. It’s rare in children and less common than non Hodgkin lymphoma. We report a case of Hodgkin lymphoma which has highlighted the value of cytological and histological examination in diagnosis. It was a 7 years-old boy with a painless cervical mass that had progressed for 2 years without treatment and increased in volume. The cervical ultrasound suspected a benign cystic mass, while the CT scan showed a tissue nodule, highly vascularized. Fine needle aspiration of this nodule was made. The cytological examination showed an inflammatory granuloma with rare atypical, binucleated cells suspect of Hodgkin lymphoma which was confirmed by histology. In developing countries, cytology is an easier and cheaper test to perform with a quick result which helps to orient the diagnosis towards Hodgkin lymphoma? However, it is necessary to make a histological diagnostic confirmation.
Pseudomyxoma peritonei (PMP) remains difficult to diagnose and has a guarded prognosis. Pseudomyxoma peritonei is a rare entity, of appendicular origin in the majority of cases. Its clinical symptomatology is not specific, the diagnosis is evoked by imaging and surgery, and confirmed by histology.
La grossesse ovarienne représente une entité rare parmi les grossesses ectopiques où l'ovaire est le siège de la nidation. Son diagnostic nécessite une démarche bien codifiée. Les particularités des facteurs déterminant, des caractéristiques histopathologiques et évolutives des grossesses ovariennes nous a conduit à porter un intérêt pour cette forme de grossesse ectopique. Nous rapportons 3 cas de grossesse ovarienne diagnostiqués dans notre service. Les trois femmes ont entre 30 à 42 ans et un terme de 13 à 37 semaines d'aménorrhée. Elles sont toutes révélées par des douleurs abdominales d'intensité variable avec un état de choc. L'examen anatomopathologique de l'annexe droite, siège caractéristique des grossesses ovariennes, a permis de confirmer le diagnostic. Elles sont toutes des grossesses ovariennes primitives juxta-corticales. La grossesse ovarienne est une entité très rare de la grossesse extra-utérine qui présente certaines particularités. Son diagnostic est difficile et se base sur des constations per-opératoires. La présence de la zone de nidation ovarienne à l'examen histopathologique est optimale pour confirmer le diagnostic. Actuellement, on admet que la grossesse ovarienne est la forme de grossesse ectopique qui peut aller à terme ou même jusqu'à une naissance vivante.
