Perineal pseudophallus unmasked: a rare case report of lipomatous hamartoma mimicking an accessory penis in an infant.

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: Rare developmental anomalies, distinct from the primary genitalia, can present as phallic-appearing outgrowths in the perineal region. Case Report: We report the case of a male infant with a perianal outgrowth resembling an accessory penis, about 3.5 cm long and 1 cm in diameter, phallic-like structure, which underwent surgical excision. Histological examination revealed mature adipose tissue (shaft region), admixed with smooth muscle bundles (Desmin-positive), nerve fibers (S100-positive), and blood vessels (CD34-positive) (glans region). Discussion: This case contributes to the limited existing literature by providing comprehensive clinical, radiological, histological, and immunohistochemical correlations, thereby facilitating a deeper understanding and differentiating the lesion from true diphallia or intersex conditions. Our findings underscore the need for multidisciplinary evaluation and thorough histopathological confirmation for accurate diagnosis and management. Conclusions: This case highlights the importance of thorough clinical evaluation and histopathological correlation in distinguishing rare congenital soft tissue lesions that may mimic genital anomalies.
