Hemangiopericytoma occurs with increasing frequency in 5th decade of life and has prediction for retroperitoneum and extremities. A case of a local recurrence and metastases of hemangiopericytoma is described.
Case presentation
Recurrence of hemangiopericytoma in the greater omentum and the jejunal mesentery as well as metastases in the retroperitoneal space were diagnosed in a 61-year-old patient who had a hemangiopericytoma of the greater omentum excised 18 years before.
Conclusion
Because of the rarity of this disease and its typical clinical course associated with late recurrence and metastases, the authors decided to present this case emphasizing the necessity of systematic oncological follow-up after the end of treatment.

Background
Hemangiopericytoma is a tumor originating from the vascular pericytes of Zimmermann. Most frequently it occurs in patients aged 40 and above with its main localization in the retroperitoneum, pelvis and lower extremities [1‐3], however, it may occur at any age in almost any part of body [4]. One of the typical features of this tumor is that both metastasis and recurrence could become apparent even after several years in remission [5‐7].
We report the case of a local recurrence and metastases in the retroperitoneum infiltrating the liver and diaphragm in a 61-year-old patient operated on due to a hemangiopericytoma of the greater omentum 18 years before.

Case presentation
A 61-year-old patient was admitted to the Department of Transplantation and General Surgery with a tumor diagnosed in the left lumbar and retroperitoneal space. Eighteen years before he had been operated for a tumor of the greater omentum with histopathological diagnosis haemangiopericytoma omenti maioris, until now with no recurrence nor distant metastases were found.
On admission the patient was in good general condition with left lumbar pain and a mobile tumor in this area. Abdominal ultrasonography (US) and computed tomography (CT) revealed a retroperitoneum space tumor with suspected infiltration of the segment VII of the liver and diaphragm.
Laboratory investigation showed no abnormalities. The patient was qualified for surgical treatment. A tumor of 5 cm in diameter in the greater omentum tightly adjacent to a transverse colon (figure 1), a tumor of 1 cm in diameter in the jejunum mesentery (figure 2, arrow) and a tumor of 12 cm in diameter located in the retroperitoneal space and infiltrating the diaphragm and the segment VII of the liver were found. No other lesions were found in intraoperative US. The tumors of the greater omentum and of the jejunum mesentery were excised whereas the retroperitoneal space tumor was removed en bloc with the infiltrated part of the diaphragm and the segment VII of the liver (figure 3, and 4). The postoperative course proved uneventful. The patient was discharged from the hospital 7 days after the procedure in good general condition with a subsequent surgical follow-up recommended.

Histopathological examination of all the lesions showed haemangiopericytoma malignum. The patient remains under the Oncology Centre and our clinical follow-up and at present, 3 months after the procedure, is in good condition.

Discussion
Hemangiopericytomas represent less than 1% of all vascular neoplasms [8]. They are highly vascular, therefore could be revealed by angio-CT and angiography (for diagnosis, tumor size, relationship to other viscera, source of blood supply) as well as undergo preoperative transarterial embolization if necessary [3, 5]. The tumors' medium size is 6.5 cm and they are encapsulated by a pseudocapsule [1, 3]. There is no grading scale for hemangiopericytoma; its malignant potential is implied by histology and clinical behavior [5]. Hypervascularity is a contraindication to a biopsy, therefore a histopathological diagnosis is established after an excision of the lesion. Potentially malignant tumors are characterized by 1 mitotic figure per 10 high-power field and moderate anaplasia. According to McMaster et al., 25 of 32 (78%) malignant tumors, 6 of 16 (37.5%) borderline lesions and no benign tumors metastasised [6].
Metastases occur by hematogenous and lymphogenous routes affecting mainly the lung, liver, bones and regional lymph nodes [1, 3, 9, 10]. Metastasis to pleura have also been reported [11]. Metastases occurring many years after excision of a primary lesion is typical of hemangiopericytoma: In our case it was 18 years. Multiple hepatic and bone metastases 12 years after an excision of a nose tumor have been reported [12]. McMaster et al., reveal that metastases became apparent in 11% of patients with malignant tumors and 7% with borderline tumors after 5 years' remission [6]. Local recurrence is also common and precedes metastases in more than 2/3 of cases [1, 13]. In two cases presented by Panda et al., it occurred after 4 months in one patient and 22 years in another [7]. Therefore long-term follow-up is essential [6]. Hypercellularity, mitotic activity, anaplasia, necrosis and hemorrhage are reported to be associated with higher malignant potential [13].
Surgical resection with subsequent radiotherapy remains the treatment of choice for hemangiopericytoma. The role of preoperative angiography and tumor embolization is also emphasized in literature [3, 5, 6]. Survival rates vary: In a review of 106 cases of hemangiopericytoma, Enzinger et al., reported 70% 10-year survival, whereas it was 50% 5-year survival according to other authors [1, 10].
Late recurrence is common in other malignancies as well. According to Shen et al., in primary cutaneous melanoma the mean disease-free interval after surgery was 182 months [14] whereas Briele et al., report seven patients in whom local or regional recurrence occured 11 to 23 years after first treatment of melanoma [15]. Another neoplasm after a treatment of which long-term follow-up is essential is medulloblastoma as recurrences after the Collins' risk period (i.e. age of a patient plus 9 months) have been noticed [16, 17]. The average follow-up in case of rectal cancer surgical treatment is 2 years whereas research shows that local recurrence can become evident even after 5.8 years and systemic recurrence after 7.9 years [18]. Continued long-term follow-up in patients treated for above mentioned malignancies proves beneficial [15, 17, 19].
Conclusion
Every patient treated due to a malignant or borderline hemangiopericytoma should be under long-term oncological follow-up as the risk of recurrence and distant metastases even after many years is very high.

Selbstverschuldete Fehler oder unerwartete Komplikationen machen jungen Chirurginnen und Operateuren mit Migrationshintergrund offenbar besonders zu schaffen. Benötigt werden routinemäßige Programme zum Umgang mit Zwischenfällen im OP.
Offenbar muss es nicht immer die bariatrische Chirurgie sein, wenn es darum geht, durch deutlichen Gewichtsverlust auch das Krebsrisiko günstig zu beeinflussen. Eine große Kohortenanalyse zur Behandlung mit GLP-1-Agonisten wurde dazu auf der ASCO-Tagung vorgestellt.
In der Notaufnahme wird die Chance, Opfer von häuslicher Gewalt zu identifizieren, von Orthopäden und Orthopädinnen offenbar zu wenig genutzt. Darauf deuten die Ergebnisse einer Fragebogenstudie an der Sahlgrenska-Universität in Schweden hin.
Darüber reden und aus Fehlern lernen, sollte das Motto in der Medizin lauten. Und zwar nicht nur im Sinne der Patientensicherheit. Eine negative Fehlerkultur kann auch die Behandelnden ernsthaft krank machen, warnt Prof. Dr. Reinhard Strametz. Ein Plädoyer und ein Leitfaden für den offenen Umgang mit kritischen Ereignissen in Medizin und Pflege.

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
