RESUMEN
OBJECTIVE: Large pressure ulcers are a well know problem occurring frequently on immobilized patients. They can develop rapidly especially over bony prominences on the elderly, ICU patients and on patients after spinal cord injury. Plastic surgical treatment can be challenging if the defects are large and complications occur like affection of anal region or development of a Marjolin's scar ulcer. Large defects of the sacral region are well known in our university hospital. Common local flaps like gluteal rotation or (double) V-Y advancement flap are often used for the treatment of smaller defects. In special cases these therapies are not sufficient. Rarely we use fillet flap of the lower extremity to cover large sacral defects on patients who were unable to walk before. SUBJECTS AND METHOD: In this case report we demonstrate two relatively young paraplegic patients (49 and 57years old) with large sacral defect wounds. One case occurred in 2017, the other in 2019. After spinal cord injury many years ago both of them developed chronic pressure ulcers of the sacral region. In the case of 2017 a Marjolin's scar ulcer developed as a complication. Both patients had previously lost a leg during the surgical treatment. We used the other remaining leg as a fillet flap in combination with interdisciplinary rectum extirpation for sufficient surgical treatment. RESULTS: In both cases adequate coverage of the sacral defect was achieved after interdisciplinary surgical treatment including rectum extirpation. Fillet flaps were safe, even after necessary surgical revisions. In one of the cases a vacuum wound therapy and several debridements were needed. After rehabilitation the patient of the earlier case is able to fully mobilize himself in everyday life and is even able to use public transport. CONCLUSION: Using a fillet flap of the lower extremity to cover large sacral ulcers is often the last possibility of surgical treatment. Though many complications can occur, full rehabilitation and social participation is possible after fillet flap surgery even with loss of both legs. Depending on patient's motivation and availability of orthopedic technology like special electric wheel chairs and other tools full mobility can be achieved.

BACKGROUND: Littoral cell angioma (LCA) is a rare vascular tumor of the spleen. Generally thought to be benign, additional cases of LCA with malignant features have been described. Thus, its malignant potential seems to vary and must be considered uncertain. The etiology remains unclear, but an immune dysregulation for the apparent association with malignancies of visceral organs or immune-mediated diseases has been proposed. CASE PRESENTATION: We report a case of LCA in a 43-year old male patient who presented with a loss of appetite and intermittent upper abdominal pain. Computed tomography showed multiple hypoattenuating splenic lesions which were hyperechogenic on abdominal ultrasound. Lymphoma was presumed and splenectomy was performed. Pathological evaluation revealed LCA. CONCLUSIONS: LCA is a rare, primary vascular neoplasm of the spleen that might etiologically be associated with immune dysregulation. In addition, it shows a striking association with synchronous or prior malignancies. With about one-third of the reported cases to date being co-existent with malignancies of visceral organs or immune-mediated diseases, this advocates for close follow-ups in all patients diagnosed with LCA. To our knowledge, this report is the first one of LCA associated with previous pulmonary sarcoidosis and hypothesizes a TNF-α related pathogenesis of this splenic tumor.
