RESUMO
Gastric sarcoidosis is a very rare manifestation of sarcoidosis. Only few case reports have been described in the literature. We present a case of coexisting gastric and pulmonary sarcoidosis in a 56-year-old female, who presented with gastrointestinal symptoms. Gastric mucosal biopsies, transbronchial needle aspiration, and endobronchial mucosal biopsies revealed noncaseating granulomas. This case report emphasizes on early evaluation of other organ system and initiation of treatment.
RESUMO
BACKGROUND: The clinical features of leishmaniasis overlap with that of hemophagocytic lymphohistiocytosis (HLH) and the diagnosis of visceral leishmaniasis (VL) related HLH can be challenging. OBJECTIVES: To review information available on disease course, treatment, adjunctive therapy used and the outcomes of VL related HLH. METHODS: We describe an illustrative case and review all reported cases of VL associated HLH in the English literature till March 2007. RESULTS: VL associated HLH is rare, with 56 cases reported in the English literature. Clinical features lack discriminating value to recognize VL as the inciting etiology. Bone marrow aspiration (BMA) establishes the diagnosis in 78% of cases but is often negative at onset of the syndrome due to the pauci-microbial nature of the disease and patchy involvement. Repeated marrow aspiration, liver biopsy, blood cultures and serology may be required to establish the diagnosis. Liposomal amphotericin is the drug of choice. IVIG may be considered when there is an inadequate response to anti-leishmanial therapy in severe and refractory disease. CONCLUSIONS: VL related HLH is often under-recognized because of overlapping clinical features and negative marrow evaluation at onset, leading to high mortality rates.
