Xanthogranulomatous cholecystitis: Diagnosis and management.

J Visc Surg 2021 Mar 16. Epub 2021 Mar 16.

Department of digestive surgery and liver transplantation, University Hospital Center Croix Rousse, Hospices Civils de Lyon, Claude-Bernard-Lyon-1, 69004 Lyon, France.

Xanthogranulomatous cholecystitis (XGC) is a rare form of cholecystitis, characterized by the presence of xanthogranuloma, prominent yellow structures within the gallbladder wall that is very often lithiasic. When XGC presents in its pseudo-tumoral form with occasional adjacent organ involvement, it can mimic gallbladder carcinoma (GBC). The etiopathogenesis of XGC is inflammatory destruction of Rokitansky-Aschoff sinuses containing biliary and cholesterol pigments within the gallbladder wall; this leads to a florid granulomatous histiocytic inflammatory reaction.

Angiomyolipoma of the kidney: from simple hamartoma to complex tumour.

Pathology 2021 Jan 31;53(1):129-140. Epub 2020 Oct 31.

Department of Diagnostic and Public Health, Section of Pathology, University of Verona, Verona, Italy; Department of Pathology, Pederzoli Hospital, Peschiera, Italy. Electronic address:

Angiomyolipoma is the most common mesenchymal tumour of the kidney, even if for a long time it has been viewed as a hamartoma rather than a neoplasm. It belongs to a family of neoplasms, named PEComa, characterised by the constant presence of perivascular epithelioid cells that co-express smooth muscle and melanogenesis markers. Angiomyolipoma can occur in patients with tuberous sclerosis, a hereditary syndrome due to the alteration of TSC1 or TSC2 genes, or sporadically. Read More

Xanthogranulomatous change in a pleomorphic adenoma: An extremely rare variant/degenerative change. Is it fine needle aspiration induced?

Diagn Cytopathol 2021 Feb 21;49(2):E71-E74. Epub 2020 Aug 21.

Department of Pathology, ESIC Medical College & Hospital, Faridabad, Haryana, India.

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor characterized by morphological diversity, metaplastic changes, degeneration, cystic change, altered differentiation, and rarely malignant transformation, thereby may create a diagnostic dilemma on cytology. Xanthogranulomatous (XG) inflammation within a PA could be due to XG sialadenitis coexistent with PA or preoperative fine-needle aspiration cytology (FNAC) induced histologic alteration. The argument in favor of this hypothesis is that the changes seen in the histopathology would not be present in the cytology, implying that the alterations were most likely due to the traumatic injury of needling rather than spontaneous change of the lesions themselves.

Xanthogranulomatous epithelial tumor: report of 6 cases of a novel, potentially deceptive lesion with a predilection for young women.

Mod Pathol 2020 10 15;33(10):1889-1895. Epub 2020 May 15.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, 55905, USA.

Epithelial marker expression and/or epithelial differentiation, as well as "anomalous" expression of keratins, are features of some soft tissue tumors. Recently, we have encountered an unusual mesenchymal tumor composed of bland, distinctly eosinophilic, keratin-positive epithelial cells, which were almost entirely obscured by xanthogranulomatous inflammation. Six cases were identified (5 F, 1 M; 16-62 years (median 21 years)) arising in soft tissue (n = 4) and bone (n = 2) and ranging in size from 2 to 7 cm. Read More
