RESUMEN
The sinus pericranii refers to a set of clinical presentations that share a pathological communication between the scalp veins and the underlying cranial venous sinus. The nature of this connection ranges from the simple dilatation of the emissary veins, to wide connections through a calvarial bone loss leaving almost the cranial venous sinus in direct contact with the subcutaneous tissue. The authors present the case of an occipital pericranii sinus of intraoperative discovery. Congenital, post-traumatic or spontaneous, this anomaly is most often frontal and located on or close to the midline. The usual clinical presentation is that of a soft mass that empties to the pressure while standing, while it fills in all situations that increase the intracranial pressure (Valsalva maneuver ). The diagnosis is not always easy to establish, and relies on a bundle of clinical and radiological arguments. Through a review of the literature we propose to focus on the clinical features, diagnostic means and therapeutic options of this rare entity.

INTRODUCTION: Forty percent of non-Hodgkin lymphoma (NHL) are located in extranodal sites. The palatal location of chronic lymphocytic leukemia (CLL) is usually observed at a late stage of the disease. CASE: We report the case of a 62-year-old male patient managed for 8 years for CLL, having presented with a soft palatal tumor in the last 2 years. The diagnosis of CLL was made by immunohistochemistry. The patient was given 6 courses of chemotherapy combining fludarabine, cyclophosphamide, and rituximab. DISCUSSION: The diagnosis of CLL requires immunohistochemistry. Chemotherapy is the first line treatment. The complication may be an aggressive lymphoma (Richter).

INTRODUCTION: Synovial sarcoma is a malignant soft tissue neoplasm which occurs most of the time in teenagers and young adults. Facial, and especially parotid gland localization, is very uncommon. CASE REPORT: A 15-year-old male patient, with no prior history, was hospitalized for swelling in the left parotid area noted 5 months before. The mass was painful and there was no facial paralysis. A CT scan revealed a tumoral process of mixed density in the left parotid gland. The thorax and abdominal CT scan was normal. The patient was initially treated by surgery and adjuvant chemotherapy. He died, 8 months after this multimodal therapy. DISCUSSION: Five percent of salivary gland primitive tumors are of mesenchymatous origin, 0.3 to 1.5% of which are sarcomas. The diagnosis of parotid gland synovial sarcoma is confirmed by immune-histochemistry and cytogenetic tests. Surgery combined to radiotherapy seems to be the best treatment.
