Tumor antigens in neoplasms of the human parotid gland

Journal of Oral Pathology & Medicine, 1982
In a collection of parotid gland tumors the presence of different antigens was studied by immuno‐histochemical methods. The series was composed of different tumors: adeno‐ and cystadenocarcinomas, adenoid‐cystic carcinomas, salivary duct carcinomas, mucoepidermoid tumors, squamous cell carcinomas and anaplastic carcinomas.The following substances were ...

Blastic Plasmacytoid Dendritic Cell Neoplasm Expressing the CD13 Myeloid Antigen

Acta Haematologica, 2011
Blastic plasmacytoid dendritic cell neoplasm (BPDCN), currently considered to originate from immature plasmacytoid dendritic cells (DC), is a rare and aggressive CD4+CD56+ neoplasm that frequently involves the skin and bone marrow.

Squamomelanocytic tumor: a new case of a unique biphenotypic neoplasm of uncertain biological potential

Journal of cutaneous pathology, 2009
Squamomelanocytic tumor is an uncommon cutaneous neoplasm composed of an admixture of melanocytic and squamous cellular phenotypes. We describe a case of this tumor in a 94‐year‐old man who presented with a nodule on the back.

Colonic Neoplasms

Archives of Surgery, 1977
Estrogen receptor protein was found in 24% of colonic neoplasms. Presence of estrogen receptor activity was independent of age or sex of the patient, state of differentiation or spread of the tumor, and concentration of carcinoembryonic antigen in the tumor.

CD5+ extranodal marginal zone B-cell (MALT) lymphoma. A low grade neoplasm with a propensity for bone marrow involvement and relapse.

American Journal of Clinical Pathology, 1996
Three cases of extranodal marginal zone B-cell lymphoma (low grade B-cell lymphoma of mucosa-associated lymphoid tissue [MALT] type) in which the neoplastic B cells expressed the CD5 antigen are reported. The patients included 2 men and 1 woman, aged 44,

Staining of Melanocytic Neoplasms by Melanoma Antigen Recognized by T Cells

The American Journal of Dermatopathology, 2000
We stained benign melanocytic nevi and malignant melanoma with antibodies to melanoma antigen recognized by T cells (Mart-1) to determine if this was useful in differentiating benign from malignant melanocytic neoplasms. Forty-five primary malignant melanomas and 71 benign melanocytic nevi were stained with antibodies to Mart-1.

Carcinoembryonic antigen: its role in malignant extraintestinal neoplasms

Journal of Chemotherapy, 1997
Carcinoembryonic radioimmunological research has attracted the attention of researchers, clinicians and oncologists for a number of years 1. However, its validity in the early diagnosis and the follow-up of a variety of cancers is still a subject of controversy.

Five novel cell surface antigens of CNS neoplasms

Journal of the Neurological Sciences, 1989
Optimal monoclonal antibody-mediated immunotherapy requires the identification of tumor-restricted cell surface antigens. We have identified and partially characterized 5 new monoclonal antibodies generated against malignant astrocytoma, medulloblastoma, neuroblastoma and melanoma which were used to define 5 neuroectodermal tumor antigenic systems.

Paraneoplastic temporal lobe epilepsy with testicular neoplasm and atypical amnesia

Neurology, 1994
We report a patient who, at age 38, presented with temporal lobe seizures and an atypical memory disorder 3 years before the discovery of a testicular tumor. Detailed neuropsychological testing revealed a relatively isolated amnestic syndrome.

Preferentially Expressed Antigen in Melanoma Immunostaining in a Series of Melanocytic Neoplasms

The American Journal of Dermatopathology, 2021
Abstract: In their 2018 article, Lezcano et al [AJSP 2018(11):1456] show that diffuse tumor cell nuclear reactivity for Preferentially expressed Antigen in Melanoma (PRAME) is a feature of melanoma and that benign and atypical melanocytic tumors are PRAME negative or show only focal positivity for PRAME.
