Diagnostic Challenges for Clinicians in Lobular Breast Carcinoma With Peritoneal Carcinomatosis: A Case Report of an Immunocompromised Patient.

Peritoneal carcinomatosis (PC) is a common condition in oncology. The lack of specificity in radiological and clinical characteristics of carcinomatosis makes their etiological diagnosis difficult. Metastatic infiltrating lobular breast cancer with PC is also a common occurrence in daily medical practice. We report the case of a 45-year-old female patient with chronic renal failure undergoing hemodialysis, admitted for lobular breast carcinoma with bone and peritoneal metastases. The surgical exploration including a biopsy revealed peritoneal tuberculosis. The focus of this paper is to discuss the diagnostic traps associated with PC in malignant tumors to highlight the importance of pathological evidence in such cases.

Malignant transformation of hepatocellular adenoma: report of a case.

Hepatocellular adenomas are benign liver tumours that occur mainly but not exclusively in young women taking contraceptives. Their malignant transformation into hepatocellular carcinoma is a rare complication that has been rarely reported in women taking contraceptives. The purpose of our work is to remind the epidemiological and diagnostic features of malignant transformation of hepatic adenomas by reporting the case of a hepatocellular carcinoma developed from a hepatocellular adenoma diagnosed within the Pathology Department of the Mohammed VI university hospital of Oujda.

Primary angiosarcoma of the breast: a case report.

Primary angiosarcoma of the breast is an extremely rare tumour with a difficult diagnosis and poor prognosis. We report a case of primary breast angiosarcoma diagnosed in the pathology department of the University Hospital of Oujda. An analysis of the epidemiological, diagnostic and therapeutic aspects of this type of tumour is made in this manuscript. Mastectomy is the standard treatment; the place of radiotherapy and chemotherapy is not well established. We report a case of a 18- year-old woman having an infectious symptomatology of the right breast for which she received an anti-infectious therapy inducing regression of inflammatory symptoms presented with a quick growing mass. Initial core needle biopsy showed a malignant vascular proliferation. The patient underwent a mastectomy. The tumor histology showed papillary formations and vascular structures lined by atypical cells with hyperchromatic nucleus and eosinophilic cytoplasm. The tumor cells expressed CD34 and CD31 but were negative for cytokeratin. The diagnosis of angiosarcoma grade I was made. The patient is now receiving chemotherapy. She is still alive.
