Histiocyte-rich rhabdomyoblastic tumor easily misdiagnosed as rhabdomyosarcoma: a case report.

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
backgroundHistiocyte-rich rhabdomyoblastic tumor (HRRMT) is an extremely rare tumor of uncertain origin. Morphologically, it closely resembles inflammatory leiomyosarcoma (ILMS) without smooth muscle differentiation, making clinical diagnosis particularly challenging. Due to its rarity, HRRMT is often misdiagnosed as rhabdomyosarcoma, leading to unnecessary aggressive treatment. CASE PRESENTATION: A 62-year-old male was admitted to the hospital after an incidental discovery of a mass on his right thigh, first noticed seven days prior. Clinical examination revealed a well-circumscribed, painless mass measuring approximately 5 × 6 cm. Ultrasound and magnetic resonance imaging (MRI) suggested rhabdomyosarcoma in the distal sartorius muscle. However, histopathological analysis following surgical resection confirmed HRRMT. The patient did not undergo postoperative radiotherapy or chemotherapy, and no recurrence was observed during six months of follow-up.
conclusionsHRRMT is a rare tumor with favorable biological behavior. Given its morphological overlap with ILMS and rhabdomyosarcoma, early and accurate diagnosis is essential to prevent overtreatment. Extensive surgical resection remains an effective therapeutic approach. We report a case of HRRMT that is easily misdiagnosed as rhabdomyosarcoma, which will be a valuable case.
