Histological and Immunohistochemical Characterization of a Histiocytic Sarcoma Associated With a Follicular Lymphoma in a Ring-tailed Lemur (Lemur catta).

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
A 20-year-old neutered male ring-tailed lemur (Lemur catta) diagnosed with an intrathoracic mass died during surgical excision. Morphological characteristics of the mass during necropsy were consistent with a mediastinal abscess in the left hemithorax. Histological examination identified a disseminated histiocytic sarcoma involving spleen, kidneys, multiple lymph nodes, diaphragm and parietal pleura, as well as a concurrent follicular lymphoma in a separate lymph node. A mixed metastatic infiltrate composed of both neoplasms was found within the capsule of the intrathoracic abscess. Immunohistochemical analysis (Iba-1, CD3, PAX-5, IRF-4, pancytokeratin AE1/AE3 and Ki-67) confirmed both neoplasms and revealed mild IRF-4 immunoreactivity for histiocytic sarcoma cells. The histomorphologic and immunohistochemical features of the histiocytic sarcoma in this Lemur catta were characteristic of this condition in other species. This report documents the first case of histiocytic sarcoma in Lemur catta, providing novel histopathological and immunohistochemical insights of this condition in prosimians.
