RESUMO
Myxoid endometriosis, a rare entity, is part of the histological changes that can occur in endometriosis. Pathologists must know the histological guidelines for the morphological recognition of this entity, as well as the histochemical and immunohistochemical techniques that support diagnosis, and define the morphological characteristics of myxoid endometriosis. In the present work, we propose diagnostic guidelines and primary differential diagnoses using special histochemical techniques and immunohistochemical reactions to recognize this entity.
RESUMO
Tuberculosis (TB) is an opportunistic infection 20 to 74 times more frequent in immunocompromised patients compared to the general population. The prevalence with renal transplant had a 0.5% to 15% incidence. The infection could be pulmonary or extrapulmonary (EPTB). The EPTB accounts for almost 20% of TB cases in immunocompetent people and 50% in positive human immunodeficiency virus cases. In this case report, we present a patient who attended the emergency room because of chronic diarrhea, abdominal pain, loss of weight, nocturne diaphoresis, and intermittent fever. A computed tomography scan showed retroperitoneal ganglionic conglomeration. He got into an exploratory laparotomy for histopathology specimens and paraganglionic fluid culture to a Gene Xpert MTB-RIF Assay G4, positive for rifampicin resistance tuberculosis. After an individualized treatment, trying to protect the graft's remaining function, the patient returned with acute abdominal pain and pancreatic enzymes elevation; the antibiotic management had to be suspended until the return of renal function.
