cholecystitis is a rare variant of chronic cholecystitis, which can involve adjacent organs including liver, colon and duodenum mimicking gallbladder cancer.
It predisposes some serious complications with other diseases such as xanthogranulomatous
pyelonephritis, perinephric abscess, emphysematous, renal abscess and UTI.3,4 Delayed diagnosis can be seen due to the atypical symptoms.5
Foreign-body giant cells and xanthogranulomatous
inflammation were also detected on the serosal surface (Figure 4).
Others included adenomyoma (9.09%, n = 1), papillary hyperplasia (9.09%, n = 1), cholesterolosis (9.09%, n = 1) and xanthogranulomatous
cholecystitis (9.09%, n = 1) (Table 5).
They include early-stage cancer and advanced cancer that has advanced to the SS stage or further, in addition to nonneoplastic lesions of the adenomyomatosis (ADM) and xanthogranulomatous
cholecystitis (XGC) (Figures 1(c) and 1(d)).
Tumors or conditions rated as intermediate include inflammatory myofibroblastic tumors (IMT) [297-300], a solitary fibrous tumor (SFT) , desmoid fibromatoses [302, 303], a hemangiopericytoma , and a Castleman's disease , while benign tumors and conditions include dermoid cysts [301, 306], teratomas [307, 308], leiomyomas [309, 310], (fibrous) hamartomas [311, 312], a hemangioma , a fibroadenoma , malakoplakia , abscesses [316-318], a xanthogranulomatous
urachitis , a urachal tuberculosis , actinomycosis [321-323], an endometriosis , a perforated colonic diverticulitis , and even a fishbone within an urachal cyst .
pyelonephritis (XGP) is a chronic inflammatory renal condition .
pyelonephritis (XGP) is an uncommon but distinct form of chronic infective pyelonephritis that typically presents in a woman in her fifth or sixth decade of life with abdominal pain, fever, palpable mass, anorexia, weight loss, hematuria, dysuria, and a persistent urinary tract infection that is resistant to antimicrobial therapy.
prostatitis is a rare form of nonspecific granulomatous prostatitis distinguished by presence of xanthoma cells.
