Chronic Myelogenous Leukemia (CML) is a myeloproliferative neoplasm characterized by proliferation of Philadelphia positive clonal pluripotent hematopoietic cells. Bleeding is a rare presentation of CML that can occur due to platelet dysfunction. Both pre-treatment and post-treatment platelet function abnormalities in CML have been described in the literature. We describe a rare case of childhood CML who presented with mucocutateous bleeding manifestations. On laboratory workup, a Glanzmann Thrombasthenia (GT) like platelet phenotype was demonstrated along with confirmation of diagnosis of CML in chronic phase. The acquired nature of platelet function defect was confirmed by demonstrating recovery of platelet antigens glycoprotein IIb/IIIa after achieving complete hematological response with Imatinib. Due to presenting complaint of bleeding diathesis and absence of hepatosplenomegaly, the case was undiagnosed for CML until the patient reported to us. Careful evaluation of complete blood counts, peripheral blood picture and detailed laboratory workup was the window to proper diagnosis and treatment in this case.
Spindle cell rhabdomyosarcoma is a rare variant of embryonal rhabdomyosarcoma that affects young males and most commonly involves the paratesticular region. We report a case of paratesticular spindle cell rhabdomyosarcoma in a 14-year-old boy, who presented with a painless scrotal mass. Left inguinal orchidectomy was performed. Histopathological and immunohistochemical examination of the mass revealed spindle cell rhabdomyosarcoma of the paratesticular region.
Anti-neutrophil cytoplasmic antibody (ANCA)-associated crescentic glomerulonephritis is an important cause for rapidly progressing glomerulonephritis. It is generally classified under pauci-immune glomerulonephritis. However, 12%-18% of ANCA-associated crescentic glomerulonephritis show immune-complex deposits causing a diagnostic dilemma. We report 2 cases of ANCA-mediated glomerulonephritis with associated immune-complex deposits. First case is a 19-year-old female patient presented with fever and bilateral lower limb purpura since one day. Immunologic work-up was normal except positivity for cytoplasmic or c-ANCA by indirect immunofluorescence (IF). Kidney biopsy showed presence of segmental cellular crescent with fibrinoid necrosis. IF showed strong fine granular positivity for IgG, IgA, C3, C1q, kappa and lambda along the glomerular capillary walls. Second case is a 20-year-old male presented with low grade fever for last one month and vomiting for last two days. Immunologic work-up was unremarkable except positivity for cytoplasmic or c-ANCA by indirect IF. Kidney biopsy showed 14 glomeruli of which 8 glomeruli showed cellular crescents. IF for IgG, IgA, C3, kappa and lambda was done, which showed strong fine granular positivity along the glomerular capillary walls. Both the cases were treated with intravenous methylprednisolone and oral prednisone on a weaning regimen, and monthly therapy of intravenous cyclophosphamide. The maintenance phase consisted of mycophenolate mofetil and oral prednisone administrated in alternate-day low-dose regimen. Both the patients are on regular follow-up and are doing well.These immunecomplexes act synergistically with ANCA to cause more severe damage to the kidneys with a poorer outcome. Thus a prompt diagnosis and management of these patients is crucial.
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.
