The circulating cells arriving at the formation site of the experimentally induced lung granuloma were quantitatively and qualitatively determined during their development by estimation of alkaline phosphatase active free cells. These represent 32 per cent the 2nd day and 27 per cent the 4th, of all
Five out of eight consecutive cases with initial symptoms of a 'midline granuloma' were identified as malignant histiocytosis (histiocytic sarcoma) which within 5 months to 4 years led to generalization and death. The three remaining cases also fulfilled the morphological criteria of this type of
Granuloma annulare is a lymphohistiocytic process of unknown cause characterized by necrobiotic dermal papules. Acetone-fixed frozen sections of eight granuloma annulare lesions were studied for the presence of T-cell subsets, using monoclonal antibodies to T-cell surface antigens. The palisading
A case of giant cell granuloma (GCG) that occurred in the right temporal bone is reported. The lesion showed histologic features identical to GCG. The multinuclear giant cells (MGCs) in the lesion showed strong reactivity with CD68, but patchy staining for myeloid/histiocyte antigen,
Neurofibromatosis type 1 (NF1) is an autosomal dominant inherited disease affecting about 1:3000 humans. Neurofibromas are benign soft tissue tumors. Giant cell granuloma (GCG) is a benign tumor-like lesion that is preferentially located in the jaws. GCG can develop in NF1 patients. A 7-year-old
A 20-year-old man presented with a rare case of germinoma with a large component of epithelioid cell granuloma manifesting as oscillopsia. Magnetic resonance imaging demonstrated a mass in the pineal region with homogeneous enhancement with gadolinium. Craniotomy was performed, ending in biopsy. The
BACKGROUND
Giant cell granulomas of the jaws are lesions that arise either peripherally in periodontal ligament and mucoperiosteum or centrally in the bone. The aim of this study was to evaluate expression of CD68 and tartrate-resistant acid phosphatase (TRAP) proteins in multinucleated giant cells
A 71-yr-old male presented with a 2-month history of fever, malaise, and weight loss. Physical exam revealed chorioretinitis. Laboratory studies were notable for elevated levels of alkaline phosphatase, gamma-glutamyl transpeptidase, aspartate transaminase, and alanine transaminase. Immunoglobulin G
Intraabdominal pseudotumor of the plasma cell granuloma type in a 19-year-old man is reported. The patient presented with fever and weight loss lasting months, and the laboratory findings revealed high sedimentation rate, hypochromic, microcytic anemia, thrombocytosis, elevated alkaline phosphatase,
