Breast Metastasis of Extraskeletal Myxoid Chondrosarcoma: A Case Report.
Article in The American journal of case reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundExtraskeletal myxoid chondrosarcoma is a unique and distinct clinicopathological entity in terms of its origin, morphology, and biologic behavior. Despite being a slow-growing tumor, it has a high rate of local recurrences and history of metastases to uncommon sites like the mandible, liver, retroperitoneum, right ventricle, pancreas, and central nervous system. Here, we report a very unique case of extraskeletal myxoid chondrosarcoma that metastasized to the breast, which itself is a very rare site for metastases. CASE REPORT: A 58-year-old woman presented with a large, firm, and tender soft-tissue mass (6.0×7.0 cm) underneath the sole of the left foot. A computerized tomography (CT) scan showed a heterogeneous lobulated mass in the plantar aspect of the forefoot, measuring 8.6×8.0×7.1 cm. Punch biopsies revealed histology consistent with extraskeletal myxoid chondrosarcoma. Metastatic work-up was negative. The mass was fully resected with left below-knee amputation. The histology of the resected mass was consistent with extraskeletal myxoid chondrosarcoma. A follow-up CT showed a new right breast nodule along with metastases to lung and bones. The results of the core needle biopsies of the right breast masses seen on mammogram were morphologically identical to extraskeletal myxoid chondrosarcoma.
conclusionsAlthough rare, metastases to the breast should be considered in the differential diagnosis of a breast mass. A close long-term follow-up is needed due to the unpredictable behavior of extraskeletal myxoid chondrosarcoma and the high frequency of local recurrences, metastases, and death due to disease.
