Chondroid Syringoma of the Nasal Ala: 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
Chondroid syringoma, also known as mixed tumor of the skin, is a rare benign cutaneous adnexal neoplasm characterized by both epithelial and mesenchymal differentiation. It most commonly occurs in the head and neck region and usually presents as a solitary, slow-growing, painless dermal or subcutaneous nodule. Because of its nonspecific clinical and dermoscopic presentation, the diagnosis is rarely suspected before histopathological examination. We report a case of a 73-year-old male with no significant medical history who presented with a progressively enlarging flesh-colored nodule of the nasal ala evolving over one year. Clinical examination revealed a well-demarcated, firm, painless, round nodule measuring 7 mm in diameter, adherent to the overlying skin, with a smooth surface. Dermoscopic examination revealed a central pigmented structureless area, peripheral white dots, linear vessels, and whitish areas, resulting in a nonspecific dermoscopic pattern. The main clinical differential diagnoses included nodular basal cell carcinoma, epidermal inclusion cyst, amelanotic nevus, neurofibroma, and chondroid syringoma. An excisional biopsy was performed. Histopathological examination showed a benign adnexal tumor composed of numerous ductal and tubular epithelial structures embedded within a myxoid to chondromyxoid stroma, consistent with chondroid syringoma. Surgical margins were free of tumor. No recurrence was observed after two years of follow-up. This case highlights the importance of considering chondroid syringoma in the differential diagnosis of long-standing nodular lesions of the nose and emphasizes the role of complete surgical excision and histopathological confirmation.
