Paraneoplastic vasculitic neuropathy has been recently described. We report the first case of this disorder which responded both clinically and electrophysiologically to cyclophosphamide treatment. A 54-year-old woman with a history of metastatic endometrial carcinoma in remission had asymmetrical polyneuropathy, electrophysiological findings consistent with a diffuse axonal neuropathy, high sedimentation rate and spinal fluid protein, and microvasculitis with axonal degeneration on nerve biopsy. The patient was treated with 150 mg of cyclophosphamide daily with gradual clinical and electrophysiological improvement.

2.1. History and clinical-gynecological investigation including a Pap smear are the first step in the clarification. The history should make sure if there is in fact bleeding from the genital and not from the urological or the intestinal region. Drug intake should be recorded, and risk factors for the development of endometrial carcinoma should be considered. This will not affect further investigation. The clinical-gynecological investigation should prove the source of postmenopausal bleeding according to the anatomical site--uterine, infra-, or suprauterine. The causes of infrauterine bleeding may easily be diagnosed by means of inspection of the external genitalia and further by using a speculum. The causes of uterine bleeding are of major importance. Cytology and colposcopy, supported by bimanual investigation, exclude cervical carcinoma as a cause of bleeding. Atypical endometrial cells on the cytological smear arouse suspicion of endometrial carcinoma. 2.2. Transvaginal sonography (TVS) is the next step if the above-mentioned investigations are negative. Both adnexa should always be investigated and the findings sonographically documented, so that solid cystic masses in the adnexal area can be better identified as suprauterine causes of postmenopausal bleeding. Then the uterus should be investigated. Further procedures are decided from the results of measurement of the longitudinal section of the endometrium at the level of maximum endometrial thickness. If the endometrial thickness is _<4 mm, an observant attitude can be assumed. After 3 months the patient should be controlled against using TVS. If bleeding recurs or the endometrial thickness is >4 mm on TVS, the procedure given in subparagraph 2.3 should be followed. In case the endometrial thickness is >4mm or not measurable, a histomorphological investigation according to subparagraph 2.3 should be performed. In such cases, saline infusion sonohysterography(SIS) is useful as a simple method to supplement TVS. It can aid in the decision making as to which further, more invasive measures should be taken (endometrial biopsy/hysteroscopic resection). Computerized tomography or magnetic resonance imaging are, as a rule, not indicated in patients with postmenopausal bleeding. 2.3. A definite diagnosis is possible only on the basis of a histological investigation. If TVS or SS show evidence of a polypoid state, removal under hysteroscopic control is the diagnostic method of choice. In cases of symmetrical or asymmetrical thickening of the endometrium on SIS, a less invasive biopsy may be sufficient. If the biopsy specimen does not yield representative diagnostic material, one should proceed as described above. A fractionated curettage should as a rule not be performed solely, but in combination with hysteroscopy.

Paraneoplastic syndromes (PNS) are a heterogeneous group of symptoms which are indirectly caused by primary or metastatic tumor. Paraneoplastic polyneuropathy (PNP) is mostly related to small cell lung cancer (5%), prostate, gastric, and breast cancer. Only sporadic cases have been reported to be associated with endometrial cancer. We present a case of a premenopausal woman with severe vasculitic, asymmetric sensorimotor polyneuropathy that developed in conjunction with an endometrial carcinoma responding to surgical therapy of primary tumor combined to steroid therapy. Neurological symptoms such as asymmetrical sensorimotor deficits and painful paresthesias are suspicious when they occur in otherwise healthy women with no medical history. The phenomenon of a paraneoplastic syndrome can point to an underlying malignancy and can be used as marker of progression or regression of the tumor. Due to the rarity of PNP, there is no standard treatment. Recommended therapy is stage-adjusted treatment of the primary tumor.
