Cytophagic and S-100 protein immunoreactive myeloid leukemia cutis.
Myeloid leukemia cutis (LC) is the cutaneous involvement by neoplastic leukocytes of the myeloid series. Myeloid LC may occur de novo or concurrently with acute myeloid leukemias, chronic myeloid leukemias, other myeloproliferative disorders or myelodysplastic syndromes. We describe an unusual case of cytophagic S-100 protein immunoreactive leukemia cutis presenting in an 87-year-old woman with...
متن کاملDistribution of immunoreactive S-100 protein in pediatric brain tumors.
The distribution of S-100 proteins was examined in 98 pediatric brain neoplasms with rabbit antiserum to S-100 protein, utilizing the peroxidase-antiperoxidase (PAP) immunohistochemical technique. Positive cytoplasmic immunoreactivity was present in 22 of 24 astrocytomas, both oligodendrogliomas, eight of 13 ependymomas, all 11 choroid plexus tumors, all nine schwannomas, two of six meningiomas...
متن کاملLeukemia cutis from CD56 positive, myeloperoxidase negative acute myeloid leukemia.
Acute myeloid leukemia (AML) is a clonal expansion of myeloid blasts in peripheral blood, bone marrow, or other tissues. Cutaneous manifestations of leukemia are either specific or nonspecific. Specific lesions result from direct infiltration of the skin by leukemic cells. We present a case of myeloid leukemia cutis manifested by erythematous asymptomatic nodules and plaques distributed on the ...
متن کاملS S 100 Calcium - Binding Protein ▶ S 100 Proteins S 100 Proteins
S100 proteins were first discovered in 1965 by Moore as a major protein fraction (0.6% of total soluble protein) isolated from bovine brain (Moore 1965). The protein was given the name S100 due to its high solubility in saturated ammonium sulfate. Later experiments showed the S100 protein fraction constituted two different dimeric species comprised of two b protomers (S100B) or an a, b heterodi...
متن کاملS 100 P ( S 100 calcium binding protein P )
S100P protein consists of 95 amino acids with a molecular weight of 10.4 kDa. S100P is a Ca binding protein that belongs to S100 family ("Soluble in 100% saturated solution with ammonium sulfate") which was first isolated from human placenta and is therefore designated as "P". S100 family includes at least 26 members, which are thought to be expressed only in vertebrates and are present in a ti...
