Only 9 cases of xanthoma or cholesterol granuloma were recorded in the literature prior to the report of 20 cases of xanthoma of the choroid plexus by Wolf, Cowen, and Graham (26), of which 1 (their case 8) was published separately (25). Cholesterol granuloma in the ventricular system of man was first described by Blumer (2) under the term "cholestomatous endothelioma." Other terms employed wer...

Very few cases other organs have been reported, to our knowledge none reported larynx. The main pu...

Cholesterol granuloma is a well-characterized entity comprised of a foreign-body giant cell-reaction that forms in response to the presence of cholesterol crystals. It is usually found in the middle-ear or mastoid process in patients with diseases associated with chronic inflammation such as cholesteatoma and otitis media. They are rarely seen in the mediastinum. Osseous metaplasia is an exceed...

Granulomatous disorders include a wide variety of infectious and non-infectious conditions with heterogeneous clinical courses considerable constraints affected organs. We take cutaneous sarcoidosis as model disease to acquire new insights into the pathomechanisms granulomas. combined single-cell high-dimensional spatial transcriptomics fluorescently labeled antibody detection for protein expre...

Cholesterol granuloma (CG) is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, and highly uncommon in the paranasal sinuses. This article reports a case of a 30 year-old man, with complaints of postnasal discharge, cough and itching in bilateral ears. CT imaging showed polypoidal mass in left maxillary sinus. Endosco...
