Mucormycosis is an uncommonly encountered fungal infection in solid organ transplantation. The infection is severe and often results in a fatal outcome. The most common presentations are rhino-sino-orbital and pulmonary disease. We describe a rare case of gastric mucormycosis in a patient with a combined liver-kidney transplant affected by glycogen storage disease type Ia. A 42-year-old female patient presented with gastric pain and melena 26 days after transplantation. Evaluation with upper endoscopy showed two bleeding gastric ulcers. Histological examination of gastric specimens revealed fungal hyphae with evidence of Mucormycetes at subsequent molecular analysis. Immunosuppressive therapy was reduced and antifungal therapy consisting of liposomal amphotericin B and posaconazole was promptly introduced. Gastrointestinal side effects of posaconazole and acute T-cell rejection of renal graft complicated management of the case. A prolonged course of daily injections of amphotericin B together with a slight increase of immunosuppression favored successful treatment of mucormycosis as well as of graft rejection. At 2-year follow-up, the woman was found to have maintained normal renal and liver function. We conclude that judicious personalization of antimicrobial and antirejection therapy should be considered to resolve every life-threatening case of mucormycosis in solid organ transplantation.
Eccrine poroma (EP) is a rare benign adnexal tumor that may mimic benign or malignant tumors and differential diagnosis may be difficult under clinical and dermoscopic examination. Reflectance confocal microscopy (RCM) examination may add important information to diagnosis and subsequent management of solitary lesions for which dermoscopy can be challenging. The aim of the present study was to investigate features of EP at RCM in order to detect the characteristics that might aid in the differential diagnosis of EP versus other solitary lesions (benign or malignant). Secondary objective was to correlate the resulting features with histopathological findings. This monocentric retrospective observational case–control study included all EPs registered with RCM between January 2007 and May 2018. Control cases were benign or malignant lesions similar in clinical appearance, morphology, and dermoscopic features to EPs. RCM evaluators were blinded to clinical‐dermoscopic images and to final histopathological diagnoses. Finally, RCM‐histopathological correlation was performed. A total of 11 EPs and 33 controls were included in the present study. Among RCM parameters, “cords without palisading,” “dark holes,” “prominent vascularization” and “abundant stroma” resulted positively associated with EP in univariate analysis. RCM features correspond to the histopathological diagnosis of EP in 97% of cases, as illustrated by the cluster analysis. An excellent correlation between diagnostic features of conventional histopathology and RCM was observed. RCM assists in the differential diagnosis of solitary lesions, allowing to reach a correct diagnosis of EP through the identification of its four characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
