Imaging appearance of isolated diffuse neurofibroma of nipple areolar area: a case report.

Sporadic neurofibromas of the nipple-areolar complexes are exceptional even in patients with neurofibromatosis. Diffuse neurofibroma is an uncommon subtype of neurofibroma that has received little attention in the imaging literature. As are most superficial lesions, it is often evaluated clinically and if biopsy is needed, it is usually performed without imaging. However the imaging data is quite characteristic with the aim of evaluating the extension in depth and detecting an underlying cancer. We report a case of women without a history of neurofibromatosis presenting a skin thickening disfiguring her left breast, related to diffuse neurofibroma of the nipple-areolar complexes confirmed histologically. We study echo-mammography and breast magnetic resonance imaging (MRI) findings in order to highlight its radiographics features.

Mixed ovarian germ cell tumor in a child: A case report of a rare association.

INTRODUCTION AND IMPORTANCE: ovarian tumors and especially mixed ovarian germ cell tumors are rarely seen in the paediatric population. CASE PRESENTATION: we report the case of a 13-year-old girl which was successfully treated for a mixed ovarian germ cell tumor with a favorable evolution. CLINICAL DISCUSSION: the incidence of mixed ovarian germ cell tumors, clinical manifestations, histologic distribution and prognosis are predominentely distinct in children and adolescents as compared to adult population. The diagnosis should be suspected in young girls with chronic abdominal pain and palpable swelling of the lower abdomen. Conservative surgery is the first therapeutic procedure that consists of a total resection of the mass with preservation of the reproductive function. Circulating tumor markers have the potential in diagnosis, prognostic stratification and for follow-up. CONCLUSION: mixed ovarian germ cell tumors are uncommen in children. Their management must be multidisciplinary and conservative surgery by laparotomy represent the standard of care.

Rare synovium pseudotumor of the knee.

It is a rare synovium pseudotumor that mainly concerns the male adult, of unknown etiology, espe-cially observed in the knee, especially in the suprapatellar recess. The arboreal lipoma consists of hypertrophic synovial villi and contains fat in very large quantities, so that the mass has a lipoma-tous appearance. The diagnosis is based on an MRI that shows hypertrophy of synovial villi appear-ing as a fatty signal on all sequences. However the diagnosis is established after synovial biopsy.
