chloroacetate esterase

01/01/1996 - "In both cases, the tumors were difficult to recognize histologically because the neoplasms lacked cytological evidence of granulocyte maturation, such as cytoplasmic granulation or eosinophilic myelocytes, and the Leder stains for chloroacetate esterase were negative. "
04/01/1997 - "Tumor cells in both cases were positive with a chloroacetate esterase stain. "
09/01/1995 - "The Leder stain (napthol-ASD-chloroacetate esterase) was positive in 21 (77.7%) of 27 tumors. "
09/01/1988 - "A diagnosis of extramedullary myeloid cell tumors had been made on the basis of routine histology, chloroacetate esterase cytochemical stain, and--in some cases--electron microscopy. "
08/01/1983 - "Histochemical studies showed that the tumor cells were pyroninophilic but did not have cytoplasmic immunoglobulins or activity of chloroacetate esterase and muramidase. "

12/01/2001 - "We report a unique case of aleukemic granulocytic sarcoma of the neck, originally misdiagnosed as non-Hodgkin's lymphoma (NHL), though chloroma was also suspected due to a greenish macroscopic appearance and the presence of myeloid chloroacetate esterase (CAE)+ cells. "
09/01/1996 - "As the tumour showed immunoreactivity for myeloperoxidase and chloroacetate esterase, it was reclassified as a granulocytic sarcoma."
10/15/1987 - "Histologic sections of both lymph node and lung revealed dense infiltration by sheets of cells which were cytochemically positive for chloroacetate esterase and myeloperoxidase, thus suggesting a diagnosis of granulocytic sarcoma. "
07/15/1987 - "In contrast to granulocytic sarcomas, the megakaryoblastic sarcoma did not stain cytochemically for chloroacetate esterase. "
01/01/1982 - "The differential diagnosis between malignant lymphoma and granulocytic sarcoma rests upon a positive naphtol AS-D chloroacetate esterase stain in granulocytic sarcoma. "

05/01/1989 - "Light microscopical and routine immunohistochemical studies of a cervical neoplasm in a 32 year old woman initially suggested a histiocytic lymphoma, but histochemical staining for chloroacetate esterase established the correct diagnosis. "

05/01/1989 - "Light microscopical and routine immunohistochemical studies of a cervical neoplasm in a 32 year old woman initially suggested a histiocytic lymphoma, but histochemical staining for chloroacetate esterase established the correct diagnosis. "

10/01/2004 - "Naphtol-ASD-chloroacetate esterase (NASDCE)-control stainings were performed on every positive sample to distinguish C-KIT-positive lymphoma cells from C-KIT-positive mast cells. "
01/01/1982 - "The differential diagnosis between malignant lymphoma and granulocytic sarcoma rests upon a positive naphtol AS-D chloroacetate esterase stain in granulocytic sarcoma. "
11/01/2002 - "Myelosarcomas were usually regarded by the clinicians as putative malignant lymphomas unless further evaluation, especially involving chloroacetate esterase reactions as well as immunostaining with a panel of antibodies reactive with lysozyme, myeloperoxidase, CD68, CD43, CD56, CD117 and CD34 proved their true nature. "
06/01/1983 - "Forty-seven human leukaemia/lymphoma cell lines belonging to myelocytic, monocytic, non-T/non-B, T-, and B-lineage and representing different levels of maturation as well as fresh cells from normal and leukaemic subjects were examined for immunological markers and cytochemically for acid phosphatase, alkaline phosphatase, alpha-naphthyl acetate esterase (pH 5.8 and 8.0), alpha-naphthyl butyrate esterase (pH 5.8 and 8.0), non-specific esterase, chloroacetate esterase, chymotrypsin-like protease, deoxyribonuclease II, beta-glucuronidase, sudan black, and periodic acid Schiff's staining. "
03/01/1975 - "Lymph nodes were biopsied from seven patients with the presumptive clinical diagnosis of lymphoma and studied for their ability to form spontaneous rosettes with sheep erythrocytes (T cell marker), for surface immunoglobulins (B cell marker), for cytochemical reactivity with peroxidase, alpha-naphthyl acetate and butyrate esterases, naphthol ASD chloroacetate esterase, acid phosphatase, periodic acid-Schiff, Sudan black B, and Wright-Giemsa on touch preparations, as well as in hematoxylin and eosin-stained sections.
