Abstract Background Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial-mesenchymal transition, EMT) results in HO, and the second is that factors secreted by cancer cells lead to the metaplasia of stromal pluripotent cells into osteoblasts. However, the osteogenic mechanisms remain unclear. Case presentation An 83-year-old Japanese woman underwent low anterior rectal resection for rectal cancer before presentation at our institution, in June 2018. The final diagnosis was stage IIB rectal adenocarcinoma (T4aN0M0). Histological examination did not reveal HO in the primary tumor. Thirteen months after the operation, a solitary metastatic lesion in the brain 20 mm in size and a solitary metastatic lesion in a right axillary lymph node 20 mm in size were diagnosed. The patient was treated with gamma-knife therapy for the brain metastasis. One month later, she was referred to our institution. She underwent lymph node resection. Histological examination revealed that most portions of the affected lymph node were occupied by metastatic tumor cells and that central necrosis and four small ossified lesions without an osteoblast-like cell rim were present in the peripheral region. Immunohistochemical analysis showed tumor cells positive for BMP-2, osteonectin, osteocalcin, AE1/AE3, TGF-β1, Gli2, Smad2/3, and CDX2 and negative for nestin, CD56, and CK7. Conclusion This is the first English case report of HO in a metachronous metastatic lymph node after the curative resection of HO-negative rectal cancer. Unlike HO lesions in past reports, the HO lesion did not show peripheral osteoblast-like cells, and the immunohistochemical findings indicated that the present case resulted from the EMT.

SummaryPrimary pulmonary sarcomas (PPS) are rare mesenchymal lung cancers, which do not present clinically or radiological different to lung carcinomas. Definite PPS diagnosis can only be made by histological analysis and detailed staging examinations in order to exclude a secondary pulmonary malignancy such as metastatic soft tissue sarcoma or another solid tumour. Here we present the case of a 66-year-old woman with a pulmonary mass infiltrating the diaphragm and the mediastinal adipose tissue, which was identified as leiomyosarcoma. The patient received curative surgery with complete tumour R0 resection. The prognosis of PPS is defined by tumour size, lymph node status and histological grading. Surgery is the mainstay of therapy and there is no definitive indication for adjuvant therapy for R0-resected and lymph-node-negative patients like in our case. However, multimodal therapy approaches such as (neo)adjuvant chemo- and radiotherapy can contribute to improving locoregional tumour control, which is the most important prognostic factor. With our case report we want to raise awareness for pulmonary sarcomas as a relevant proportion of rare lung cancers which have to be kept in mind during the differential diagnosis. Moreover, we aim to discuss the complex and individual interdisciplinary management.
