Unicentric Castleman disease of plasma cell type in the adrenal region: a case report and literature review.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Castleman disease (CD) comprises a heterogeneous group of lymphoproliferative disorders. Unicentric CD (UCD) involving the adrenal region is uncommon and poses diagnostic challenges because it can resemble adrenal neoplasms. Case presentation: A 37-year-old female presented with a 10-year history of intermittent hyperhidrosis and facial flushing, and a one-month history of right chest and abdominal pain. Imaging revealed a 53 mm × 42 mm heterogeneous mass in the left adrenal region with calcification and marked enhancement. Endocrine evaluation showed no hormonal hypersecretion. The patient underwent laparoscopic tumor resection. Histopathology and immunohistochemistry confirmed plasma cell type UCD, with HHV-8 negative on both serology and immunohistochemistry. Postoperative recovery was uneventful. Postoperative PET/CT and PET/MRI showed no evidence of residual or recurrent disease. At the two-year follow-up, the patient remained asymptomatic with no evidence of recurrence. Conclusion: Adrenal-region UCD is an uncommon entity that can mimic nonfunctional adrenal tumors. Complete surgical excision is curative. This case highlights the importance of including UCD in the differential diagnosis of well-defined adrenal masses without endocrine abnormalities.
