[Epidemiological and pathological profile of colorectal cancer: about 36 cases].

Colorectal cancer is classified among the most common cancers in the world (after breast cancer and prostate cancer) and it is the second digestive tract cancer in Morocco after stomach cancer. However, its incidence in our country is lower than that of western countries (2.5 to 3.

An unusual presentation of neurosarcoidosis with progressive hearing loss.

Sarcoidosis is a granulomatous disease of unknown etiology that can involve several organ system. Neurological manifestations are not common and mostly include cranial neuropathies. However, auricular disorders are rare and exceptionally inaugural.

[Primary squamous cell carcinoma of the colon: about a case].

Primary squamous cell carcinoma (SCC) of the colon is an exceptional tumor. Less than 150 cases have been reported in the literature up to the year 2014. In addition to its rarity, it is distinguished by its frequent association with other digestive neoplasias.

[Splenic marginal zone lymphoma].

Splenic marginal zone lymphoma (SMZL) is a rare B-cell lymphoma, well defined according to the 2016 WHO classification of tumors of the hematopoietic tissue, which can raise diagnostic problems. We report the case of a 72-year old patient, hospitalised for exploration of a massive splenomegaly confirmed by computed tomography (CT). Laboratory tests were normal.

[An exceptional association between retroperitoneal dedifferentiated liposarcoma and well differentiated pericolonic liposarcoma: about a case].

Liposarcoma is an extremely rare malignant adipose mesenchymal tumor. World Health Organization classifies liposarcomas into five subtypes: well differentiated, myxoid, pleomorphic, dedifferentiated and mixed. The association between multiple and synchronous location of several subtypes of liposarcomas is exceptional.

[Granulomatous spondylodiscitis: due mainly to tuberculosis but lymphoma cannot be excluded].

Lower back pain is due to multiple etiologies that make diagnosis difficult. Primitive spinal lymphoma is rare and its diagnosis often requires ultrasound-guided biopsy. A 30-year old man hospitalized for inflammatory lumbago evolving within the context of an impaired general condition.

Upper urinary tract lipoma: A case report.

Upper urinary tract (UUT) benign tumours are rare. We present a case of UUT lipoma in a 41-year-old man with left flank pain. A computed tomographic urography scan revealed an irregular thickening of the left renal collecting system wall extending from the upper calices to the renal pelvis.

Adenoid cystic carcinoma of cervix in younger women: report of two new cases.

Adenoid cystic carcinoma is a malignant epithelial neoplasm derived from the salivary glands. Primary adenoid cystic carcinoma of the cervix is extremely rare, accounting for less than 1% of all cervical carcinomas. Its origin is debatable.

Diagnosis and management challenge of a granular cell astrocytoma of the pineal region: case report.

Granular cell astrocytoma (GCA) is a rare type of infiltrative brain tumor with most reported cases occurring in the suprasellar region. A pineal localization is extremely rare, with only 4 previously reported cases in the literature. The authors describe the case of a 16-year-old boy who developed signs of increased intracranial pressure and Parinaud syndrome.

Multiple lytic lesions of the spine: a rare diagnosis of eosinophilic granuloma in an adult: a case report.

Eosinophilic granuloma (EG) is a rare benign osteolytic lesion observed rarely in adults, with only some 18 cases of spinal location reported in the literature. We present an unusual variant of EG in a 23-year-old man with radiological features of multiple spinal lytic lesions which was evocated of metastatic processes. A surgically transpedicular biopsy of the thoracic collapsed vertebrae with posterior stabilization was made.
