Adult testicular granulosa cell tumors are rare sex cord- stromal tumors of which only 45 have been previously reported. As compared with their ovarian counterparts, these tumors may follow a more aggressive course because the proportion of malignant cases is higher. We report here a unique case of a 78-year Caucasian with a left sided adult type granulosa cell tumor with a heterologous sarcomatous tumor component. A heterologous sarcomatous component has occasionally been observed in ovarian tumors but never in testicular granulosa cell tumors. The sarcomatous component showed a higher number of mitotic figures (1/Hpf) and a marked proliferation rate (up to 50% Ki 67 positive cells) compared with the granulosa type tumor component. CD 99 and the progesterone receptor were positive in both tumor components, inhibin and calretinin only in the granulosa cells, and pancytokeratin only in the sarcomatouse one. Key words: testis - ovary - granulosa cells - sarcoma - inhibin Runing title: testicular sarcomatous granulosa tumor.Virtual SlidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/6959043481207016

A 62-year-old female suffered from therapy-resistant pain in the axilla after lymphadenectomy. The pain ranged from 8-10 on the numeric rating scale (NRS) despite multimodal pain therapy (non-steroid anti-rheumatics, opioids, physiotherapy, acupuncture). A paravertebral trial injection was performed preoperatively on the laminae of the thoracic vertebrae Th 2-Th 4. As the patient responded well, a paravertebral catheter was inserted close to Th 4 directly before the revision operation took place the following day. The case study describes the possibilities of eliminating pain segmentally in the axilla and an alternative technique to a paravertebral block (lamina technique).
