Treatment Outcomes of Sinonasal Seromucinous Hamartoma: A Single-Center Experience.
Article in Journal of rhinology : official journal of the Korean Rhinologic Society, 2025. 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 AND
objectivesSeromucinous hamartoma is a rare, benign epithelial tumor of the sinonasal tract, most commonly originating from the posterior nasal septum. Accurate diagnosis is essential due to its histopathological resemblance to low-grade sinonasal adenocarcinoma. This study aimed to evaluate the clinical characteristics, diagnostic considerations, and treatment outcomes of patients with seromucinous hamartoma treated at a single tertiary referral center.
methodsWe retrospectively reviewed the medical records of six patients with histologically confirmed seromucinous hamartoma treated between January 2010 and May 2025. Data collected included demographic characteristics, presenting symptoms, imaging findings, histopathological features, and surgical outcomes.
resultsSix patients with a total of seven lesions were identified; one patient presented with bilateral nasal involvement. The mean age at diagnosis was 33.9 years, and four patients were female. The most common presenting symptom was nasal obstruction, followed by epistaxis and rhinorrhea. Lesions were primarily located on the nasal septum, while some involved the inferior turbinate and sphenoid sinus. All patients underwent complete transnasal endoscopic resection. No recurrences were observed over a mean follow-up period of 58.6 months. One patient required medial maxillectomy due to difficulty distinguishing the lesion from adenocarcinoma.
conclusionSeromucinous hamartoma may arise at atypical sites and can mimic malignant tumors. Awareness of its variable presentation, along with complete surgical excision, is essential for optimal management and to avoid unnecessarily aggressive treatment.
