Mycobacterial pseudotumor of the skin.
Article in Virchows Archiv : an international journal of pathology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Inflammatory pseudotumors have a diverse etiology, mycobacterial pseudotumor (MP) being one of them. MP is a rare entity; it has been reported infrequently in various organs and is extremely rare in the skin. We report a cutaneous MP in an immunosuppressed liver transplant recipient. The lesion consisted mostly of spindle cells, with small numbers of lymphocytes. Conventional acid-fast bacilli (AFB) stain revealed a large number of acid-fast bacilli within spindled histiocytes and the presence of Mycobacterium avium was determined by polymerase chain reaction. Given that the patient had a prior history of cutaneous squamous cell carcinoma resected and reconstructed in the same area, establishing the diagnosis was challenging. Immunohistochemical staining for lysosome-associated membrane protein was strongly positive, suggesting the presence of numerous mature lysosomes within infected spindle cells. Mycobacterial spindle cell pseudotumors can mimic malignant or benign neoplasms and should be considered in differential diagnosis of spindle cell lesions, especially in immunocompromised patients. Further studies are needed to determine mechanisms that permit the survival of mycobacteria within the lesions and that cause this unusual manifestation of infection.
