However, soft-tissue involvement is uncommon. It’s an exceptional neonatal tumor of soft tissue. The imaging characteristics of this tumor are not specific. Biopsy allows diagnosis;the histomorphological characteristics of rhabdoid tumors, their immunoreactivity to epithelial markers and vimentin, and the INI-1 loss are important tools for diagnosis. RT tumors are aggressive and have a rapidly fatal clinical course in most cases. Despite multidisciplinary therapy, the survival rate is very low. We report a rare case occurring in a male neonate who presents at birth with a voluminous right axillary mass. A CT scan showed a well-limited tumor mass with lobulated contours. An ultrasound-guided biopsy was performed on day 8, showing the morphology and immunoprofile of RT. The mass showed rapid growth. The child was admitted for respiratory distress at 3 weeks. A thoraco-abdominal CT showed an increase in the size of the mass with the appearance of multiple lymph nodes and pleural, hepatic, and renal metastases. The child died two days later.展开更多

The onset of lymphangiomas is either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. These malformations can occur in any region of the body, Lymphangiomas have marked predilection for the head and neck region (50% - 70%). The most common location in the mouth is the dorsum of tongue. If the positive diagnosis is generally easy, the therapeutic management remains controversial. We report the clinical case of a 23-year-old adult patient with cystic lymphangioma on the floor of the oral cavity extending gradually to the right submandibular region. The clinically suspected tumor was thoroughly explored using tomodensitometry. The treatment consisted of complete resection by a cervicotomy with histological examination confirming the macroscopic diagnosis of cystic lymphangioma. Follow-up at 3 years showed no recurrence.展开更多
