  • Case report Spontaneous fistulization of a Caseous calcification of the mitral annulus: an exceptional cause of stroke
    2020
    Co-Authors: Benjamin Chevalier, Patricia Reant, Stephane Laffite, Laurent Barandon
    Abstract:

    We present the case of a Caseous calcification of the mitral annulus, responsible for two strokes, in a 72-year-old female patient. The brain computed tomography (CT) scan confirmed the presence of a calcific embolus. The echocardiography showed a liquidy, pseudotumoral mass combined with numerous calcifications located in the posterior part of the mitral annulus and extending toward the inferior surface of the left ventricle. During surgery, we found a direct communication between the Caseous Necrosis and the lumen of the left ventricle at the level of its inferior wall. We performed a valve repair procedure and excision of the Caseous Necrosis, combined with injection of bioglue W into the cavity, to avoid recurrence. Six months after the procedure, the patient was in good health, and had no recurrence of stroke with a satisfactory echocardiography.

  • Caseous Necrosis in cutaneous leishmaniasis
    Journal of Clinical Pathology, 1996
    Co-Authors: E Peltier, P Wolkenstein, M Deniau, E S Zafrani, J Wechsler
    Abstract:

    A case of late stage cutaneous leishmaniasis with focal Caseous Necrosis is reported. The patient, a 30 year old Tunisian man, presented with idiopathic bone marrow aplasia. Microscopically, minimal changes were observed in the epidermis: slight hyperkeratosis and moderate acanthosis. Lesions predominated in the dermis. Epithelioid granulomas were found in the lower dermis. Some of these lesions were clearly surrounded by a ring of lymphocytes and were rarely confluent. A peculiar histological feature was the presence of focal acidophilic and slightly granular Necrosis at the centre of some the tuberculoid lesions. Focal fibrinoid Necrosis was found in the upper dermis, outside granulomas. A mild to moderate infiltrate of histiocytes, lymphocytes and plasma cells, with scanty neutrophils, was observed mainly in the upper dermis. No intracellular or extracellular Leishman-Donovan bodies were observed. Acid fast mycobacteria, however, were not detected. Leishmaniasis was diagnosed on culture of skin biopsy specimens. The presence of Caseous Necrosis could lead to diagnostic confusion and result in an erroneous diagnosis of, for example, tuberculosis, syphilis, acne agminata, and sarcoidosis with fibrinoid Necrosis. This is especially the case when parasites are scanty or absent.
