Tumoral calcinosis of unusual location in a chronic hemodialysis patient.

Tumoral calcinosis is a rare cause of intratissular calcifications in hemodialysis patients with chronic renal failure. Its frequency is estimated between 0.5 and 7% of patients. We illustrate through a case of unusual localization diagnosed in Ibn Rochd University Hospital, Casablanca, Morocco, the radiographic and scannographic aspect of this little known entity. A 40-year-old man, followed for hypertensive cardiopathy, in chronic renal failure for 12 years under hemodialysis, consulted for bilateral inguinal swellings evolving in a progressive and painless way. Biological investigations revealed hyperparathyroidism with increased phosphocalcic product. He was referred to us for radiological evaluation which revealed lesions in favor of bilateral puboinguinal tumor calcinosis. Tumoral calcinosis is a rare cause of intratissular calcifications in chronic renal failure patients undergoing hemodialysis. Pubic localization with infiltration and osteolysis of the symphysis pubis is very rare. Its main risk factors are the existence of hyperparathyroidism, an increase in phosphocalcic product and probably local traumatic factors. Tumoral calcinosis has a typical appearance on radiographs: amorphous, cystic and multilobulated calcifications of periarticular distribution. The CT scan allows a better delineation of the calcified mass. Its treatment remains controversial. The knowledge of osteoarticular manifestations of chronic hemodialysis patients, especially tumoral calcinosis by radiologists, allows to easily make the diagnosis and thus avoid invasive complementary explorations for the patient and to quickly institute an effective treatment.

Diagnostic imaging of foot mycetomas: A report on two cases.

Mycetomas caused by aerobic actinomycetes are called actinomycetomas. It is primarily localized in subcutaneous tissue but it can spread to different tissue planes including the skin, deep tissues and structures and eventually the bones. We report the cases of 2 patients referred for evaluation of soft tissue masses involving the foot. A 40-year-old male and a 25-year-old male, in both cases MRI was performed to assess the extension, which was later completed by a CT scan. MRI revealed a low intensity matrix that represents fibrosis containing multiple high intensity lesions corresponding to the mycetoma grains. Within some of the lesions a low-intensity focus was identified. This "dot-in-circle sign" on an MRI is a pathognomonic feature of mycetoma. The purpose of this work is to describe the characteristic MRI appearance of foot mycetoma.

Giant fibrous polyp issuing from the uterine cervix: A case report.

Fibrous uterine polyps are very common in women during or after menopause, and less often seen in women of child-bearing age, with a maximum of frequency between 40, and 49 years. They can have various locations in the uterus depending on the patient's age, mostly the body, and fundus. We report a rare case of cervical localization of a pedicled fibrous polyp issuing from the cervix, in a 44-year-old female patient with 3 living children and a history of miscarriage, who had been presenting breakthrough bleeding, and pelvic pain for 3 months. It is essential to remind young radiologists of the different presentations of fibrous polyps, how to explore them better and when to fear malignancy and thus insist in a histologic study, in order to help clinicians to choose the most adequate treatment option.

Eccrine porocarcinoma: an extremely rare cutaneous tumor from a radiological point of view - case report and review of the literature.

Eccrine porocarcinoma is a rare type of skin neoplasm. It represents less than 0.01% of all epithelial cutaneous tumors. Early diagnosis is the only way to minimize the mortality rate, given its aggressive nature and the high rate of local recurrence and metastasis. Clinical diagnosis is challenging and the confirmation is histological. Few studies have been published about the radiological features of eccrine porocarcinoma. We report a case of a localized eccrine porocarcinoma along with ultrasound, MRI features, and a review of the literature to highlight the role of imaging in the diagnosis and treatment plan.

[Leriche syndrome in a 20-year-old young woman: a case report]. / Syndrome de Leriche chez une jeune femme de 20 ans: à propos d'un cas.

Leriche syndrome or aortoiliac occlusive disease is a particular obliterative arterial disease of the lower limbs, consisting of thrombotic occlusion of the aortoiliac junction. We here report the case of a 20-year-old female patient with no particular past medical history, presenting with acute lower limb ischemia. Lower extremity echo Doppler showed overall decrease in arterial blood flow without visualization of endoluminal material. Lower limb angioscaner showed arterial thrombosis of the abdominal aorta extended to bilateral external iliac arteries. The patient subsequently underwent aortic-bi-iliac bypass surgery with good evolution as well as assessments for possible thrombogenic mechanism.

[Primary colonic extranasal NK/T-cell lymphoma: about a case]. / Lymphome T/NK extra-nasal à localisation colique primitif: à propos d'un cas.

To better understand this cancer, we here report the case of a 43-year old patient diagnosed with localized and isolated primary colonic NK/T-cell lymphoma without associated enteropathy, treated wih 3 cycles of AspaMetDex with a poor response who died during treatment with a clinical picture of acute abdomen. Primary intestinal NK/T-cell lymphoma most commonly affects the young subject with poor prognosis. It is difficult to distinguish between intestinal NK/T-cell lymphoma and inflammatory or infectious intestinal disorders because of its non-specific clinical and endoscopic features. The histopathological and immunohistochemical data as well as the study of DNA allow to adjust the diagnosis and to classify this lymphoma according the European Enteropathy type T-cell lymphoma (ETL).

[Primary hodgkin lymphoma of thyroid: case report]. / Lymphome de hodgkin primitif de la thyroïde: à propos d'un cas.

Primary thyroid lymphoma is a rare clinical entity, which does not exceed 5% of the diagnosed lymphomas, occur more frequently in women than in men, with a peak incidence in the sixth decade of life. The relationship with chronic thyroiditis is well known. The Hodgkin subtype even rarer; little described in the literature; Posing a diagnostic problem. Diagnostic confirmation is usually carried out on the surgical specimen. To better understand this entity, we report the case of a 64-year-old patient, with no notion of chronic thyroiditis, admitted for Hodgkin's lymphoma of the thyroid, diagnosed on an anterior cervical mass. Thyroidectomy with histopathological and immunohistochemical studies confirmed the diagnosis. The patient had received chemotherapy type ABVD (Adriblastin-Bleomycin-Vinblastine-Dacarbazine) and programmed for radiotherapy.
