Unlike visceral, lymphonodal or bone metastases, skin metastases are rare and their identification portends of a bad prognosis. They may appear as the first sign revealing the primary tumour, synchronous or developing late in the course of neglected primary cancer. We report a case of 86 year-old women witch belongs to this rare group of patients in whom cutaneous metastasis were identified before the primary cancer. This case showed the interest of biopsy and imaging in the confirmation of the diagnosis.
Coronary artery fistulas are rare congenital anomalies of coronary termination. There are 3 types: (1) cameral coronary fistulas, (2) pulmonary coronary fistulas, and (3) bronchial coronary fistulas. Left circumflex coronary artery to left atrial fistula are exceptional. Imaging, especially the CT angiogram, must establish an anatomical classification of the fistula for therapeutic purposes, by specifying its origin, its path, its size and its termination.
We report a rare case of the left circumflex coronary artery to left atrial fistula in a 31 year old man, which is an uncommon presentation of coronary termination anomalies. The CT coronary angiogram must describe the origin segment of the fistula and the drainage site which have therapeutic consequences.
Osteoblastoma is a rare benign tumor arising predominantly in the vertebrae or long tubular bones. Its naso-sinusian origin is rare and can be responsible for ophthalmological complications [1].
We report the case of 19-yeaold patient admitted to the Ophthalmology department for progressive right exophthalmia and ptosis evolving over 8 months.
The diagnosis of osteoblastoma was suspected on CT and MRI imaging and then confirmed by the anatomopatological studies. Total surgical excision was performed. Clinical and radiological evolution has been favorable.
Ewing's sarcoma is a variety of sarcoma of reticuloendothelial origin. There are atypical forms of Ewing's sarcoma, encountered in 20% of cases, where the tumor grows in the soft tissue without any skeletal connection. The imaging of extra-skeletal Ewing's sarcoma (EES) has been revolutionized by the advent of modern techniques with magnetic resonance imaging (MRI) at the forefront. Magnetic resonance imaging is an essential aid for determining target volumes for radiotherapy and for monitoring patients during chemotherapy to assess its effectiveness and for the diagnosis of local recurrences. The diagnosis is mainly based on cytogenetics and immunohistochemistry. Their prognosis is a priori poor, with the possibility of local recurrence or late metastases. We report a particular case of EES located at the retrorectal space in a 15-year-old girl revealed by gluteal pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
