Clinics and Pathology

Clinics

rare soft tissue tumour found in children and young adults

Pathology

spindle cell proliferation with myofibroblastic differenciation and an inflammatory infiltrate

Prognosis

low malignant potential and good prognosis

Epidemiology

a very few (four) cases known so far

Clinics

ALK+ ALCL without the t(2;5) (so called cytoplasmic only ALK cases) show clinical features similar to those of classical ALK+ ALCL: young age, male predominance, presentation with advanced disease, systemic symptoms, frequent involvement of extranodal sites, and a good prognosis. Nothing in particular is known concerning t(1;2) cases, as cases are not documented.

Cytogenetics

complex karyotypes and/or hidden translocation in the 2 cases with cytogenetic data; FISH analyses are essential

Genes Involved and Proteins

Gene name

TPM3 (tropomyosin 3)

Location

1q21.3

Protein description

284 amino acids, 33 kDa; coiled coil structure; role in Calcium dependant actin-myosin interaction

Gene name

ALK (anaplastic lymphoma receptor tyrosine kinase)

Location

2p23.2

Protein description

1620 amino acids; 177 kDa; glycoprotein (200 kDa mature protein) ; membrane associated tyrosine kinase receptor

Result of the chromosomal anomaly

Description

5 TPM3 - 3 ALK

Description

104 kDa ; 221 (?) N-term amino acids from TPM3 fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain); homodimerization of the fusion protein.

Expression localisation

cytoplasmic localisation (in contrast with the t(2;5)(p23;q35) with NPM1-ALK, which localizes both in the cytoplasm and in the nucleus).

Oncogenesis

TPM3-ALK is contituvely activated
