Metastatic renal cell carcinoma initially presenting as a unilateral breast lump.
Article in Radiology case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers.
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
Breast metastasis from primary renal cell carcinoma is a rare entity and infrequently reported in the literature. We present a case of a 65-year-old lady who presented to breast clinic with a 4-month history of rapidly growing right sided breast lump. She previously had a left mastectomy for breast cancer and a hysterectomy for endometrial cancer. Radiological evaluation with mammography and ultrasound revealed a large heterogeneous right breast lump with prominent vascularity which was biopsied. Histopathological and immunohistochemical features were not supportive of a primary breast carcinoma and favored metastasis from a renal tumor. The patient was unfortunately admitted to hospital due to increasing confusion and neurological symptoms and underwent whole-body cross-sectional CT imaging which demonstrated a giant tumor originating from the right kidney with associated intrathoracic, breast and intracranial metastasis. She was diagnosed with eosinophilic variant metastatic renal cell carcinoma. This case highlights the importance of considering alternative diagnoses to primary breast carcinoma in the context of an initial presentation of a unilateral breast lump.
